Were starting off a high note so were. Here at the fps Group Checking out an engine block that is almost complete and im here with mehdi the Vice President of fps group and hes going to tell me about why this uh engine block this v16 beast of an engine block is so exclusive to uh countries that you can actually count with the fingers in one hand and whats so special about making of this that not very many countries are able to make it so maybe please thank you so much for the time uh actually we are the First Company that do the maintenance of the locomotives in iranian railway, since 10 years ago we start the major overhall of the engines in our factory impar and industrial zone, right . Uh, after some years we face to a problem that we have a problem with engine blocks, this is the main parts of the engines that we have, right . So we are going to start to how to manufacture these engine block in our country, before that the. Are importing these engine blocks from foreign countries, and because of the sheer size and weight, this is five ton beast, its going to be pretty expensive to import, really unmanable, its unbelievable, thats its because its uh something that um under embargo and its very hard to find the uh countries, yeah right manufacturer to important, forget about this, we are doing the um drying. Make drawing, this is specially kind of engine blocks in all over the world, because what makes this special . All the engine blocks in the normal or general types of engines are casting, but this is fabricated engine blocks, mean we have the separate parts of the engines and we do the assemble of these, so you dont cast these different parts, no, there is no casting parts in all the. These are forged and these parts separately forged and then assemble together, so how does forging work and how is it different from casting and what kind of properties does it have that casting parts dont . Forging is um different from casting, casting you have mold and you put the melt like melted metal melted metal into the mold and after cooling the process you to have the final uh parts, but in in uh forging you have to do the you dont have the melt, metal, its goes the temperature to higher, it almost melts, almost melt, yeah, its not quite melt, and after that you put the pressure, its under the um press device, so its like you have mold, but instead of pouring metal in it, you put the pressure from both sides or like from whichever direction into this. You pressed it into the mold, because of that the characteristy of the final uh parts its different, how is it different and why is it better to use forging instead of casting . Most of the time the hardness is very important for us, the toughness is very important to us and whats the difference between hardness and toughness . Hardness is uh something that it shows the uh being put pressure or impact, it doesnt in, yeah, but in troftness you you have the bending, its how brittle. Okay, so this is tougher and harder, harder, yeah, in uh forged parts. We have the hardness and uh toughness increased increased yes okay after we do the assembling all the parts of the engine block after that we should go to the other parts mean we put the crank shaft right the liners power packs head cylinder and all together i think thats the those are the power packs yeah these are the power packs this is the v type engines its not the line one the v type engines eight cylinders on one side the other eight on the other yeah we have both sides uh we have whats the advantage of v type engines compared to the uh the space, its much smaller than the other lines one and the power of these engines are increased and we have 16 cylinder in this space, if you have one to line once the length should be five meters or so, more than five meters, now it is four, okay so when can we expect to actually see this being uh finished and then installed onto an actual train, this is the fine parts we do the test of these uh engine blocks, hope in three months we have the final engine blocks and then assemble the other parts, because we do the maintenance of the Major Overhaul of the engines before for imported engines, for imported engine blocks, no the engine the engines are working over the locomotives and when the time is ready we have to do the major or we have. We have the test device for doing the uh test and we can measure we can measure uh some parameters for the uh what we do in the major over right because of that hope in three months we have the complete engine okay heres hoping well be able to see the first train with domestically made engine block and engine as a whole uh sooner than later thank you very much for the information right along. Not all cables are built the same and so were here at the yahoot Cable Manufacturing Company where theyve where they make uh cables that are for heavy industries and in particular rail and Transportation Industry it comes to uh subway trains that are powered by electricity uh so different cables obviously have. Different levels of resistance to heat. When you think of cables, you probably think of the charging cable of your phone or your laptop or other uh home appliances. The thing with those cables is that they they are based off of thermal plastic substances and uh those thermoplastic substances are based on oil, so they have little to no resistance to heat, and when currents uh even flow into these cables uh heat is generated and the live and neutral wires. Within the cable uh can actually melt, the shielding can melt and theyre all based on oil, so they can melt and the cable itself can melt, and uh the the orking that will happen because of the live and neutral wires coming into contact with each other, can actually create a spark and actually uh you know put the whole thing up in flames, that is very unsafe kind of cable and can run through lot of. Apartments and houses, so the solution is to switch to Something Like this, or other cables that are based on silicium, the the mineral silicium, so these are not thermoplastic based substances, they are thermotets which have much higher resistance to heat, lets take a look at the the substance itself in the paste form, so this is what a silicium paste or silicon looks like, and out of these. We get these heavy duty cables, which are actually used in railway and transportation, so this red bit is made of silicium, and theres another layer of insulation that is made up of fiberglass, so the silicium layer has a resistance of up to 200 degrees celsius and the fiberglass insulation adds another 600 degrees of resistance up to 800 degrees, so uh stuff like this that you actually see here, Something Like it, this flame has actually been. Running for the past two or three days since the beginning of this exhibition and you can see that uh this uh thermals thermoset material once it is uh coming into contact with heat and flame it actually turns into ceramic and creates another better layer of insulation than silicium itself so it becomes a more insulating material and you can actually see here that the temperature is at around 800 degrees so there are different tests that need to be run. Uh to get the certificates of these cables uh to be able to use them in railway and uh the power trains uh within the subway system uh so this is a pretty good uh demonstration of how resist how resilient these cables are and this lamp has been on for this entire time uh the circuits, the the flow of electricity has not been cut for this whole time. Lets talk about another subject that is outside of a train but still with the confines of uh railway and transportation, we have the laser profilemeter and to explain more about it, i have ali salehpur, the ceo of uh kahraq fanaari to tell me about how it works and how it applies to. Hello, this device is used laser for measurement the z area and move in x and y and then have point clot and in here we can show the point clot, shows us map of whatever 3d object that is underneath it, yeah yeah yeah, we can scan everywhere, for example we can scan centimeter to centimeter, for example this one is 10 millimeter into 4 mm, whats the smallest diameter that we can actually scan in the in z1 micro . So how do we analyze this data and where do we use it . Uh and after we take a point clothe we use the software for show the topography and then uh we can put for example we can put the line like this and see the profile and see the roughness average so how much the so this is the profile so this is the scan itself the the black line and we can measure how much this line diverges from the wave that is the average of this uh this this profile and that will give us the roughness number so the the smaller this range is we can understand that the smoother the surface is correct this this uh green line yes and independ on the product we wants to scan some product is less than micro micrometer and some products is more and choose the laser and choose the device for how to scan, how to small scan of the area so this green is the difference between the the red which is the average and right so and uh the roughness so how do we use it in the Railway Industry whats the application the railway for example we wants to scan the rail and understand whats the damage on the rail we can put this device for example on the train and train moving on the rail and scan the rail and after the scan we can understand which area def deformity right and another using and we can using on the wheel when we wil using on the train they have deformation and we can scan the wheel and understand what the roughness and whats the damage on it uh thats going to be it for this particular product uh to some closing thoughts in the 10th railway and transportation expo i got see firsthand just how thorough and diverse this industry is in iran. I saw Companies Making everything from train cars, wheels, engine blocks and power inverters and lot of things in between with very few missing links, so heres hoping in the 11th, 12th or 13th version of this expo, i see less missing links and less of a way between us and making a uh a train from start to finish all by ourselves, heres hoping that happens sooner rather than later. I hope youve all enjoyed it and uh. I will see you in the next week. Ian puddick found himself controversially charged with harassment by city of London Police. This relatively minor charge resulted in raids on his home, office and accountant. You think about the allegations against din. There was overkill in the Police Approach to this, in the raids and his home, the rais on his business. It didnt seem necessary. Police interviews went unrecorded. Accusations were made against ian without any justification. If what he was saying was true, what he has done is left huge quantity of class a drugs to be sold . Is that sort of thing that a policeman would really . Really do, and worst of all, there is evidence that city of London Police were influenced by outside voices. We live in england, things are transparent, things are white than white, well theyre not, this is case of somebody standing up and not allowing themselves to be bullied by by these thugs. This headlines draw attack a Military College in central syria has left scores of people dead. Media
