There are 2 type of silicon recarb, one is with Carbon content above 15%. The other type with carbon around 8%. Those two are conventional models but silicon recarb is also available of customized specifications. The regular size is 10-50mm, sometime with 10-100mm. Lumps or briquette are all provided. Lumps were crushed from alloyed natural blocks, then selected into required standard size. Silicon recarb briquette are made from Si-C powder by briquette machines, the briquette machine provide high pressure to make powder into briquette form.
And binder will be added into raw materials to help it get better hardness. After that, drying process is the last step. Usually manufacturer can dry it under the sun by air, or into a oven which with high temperature from natural gas heat.
The applications of silicon recarb: metallurgical deoxidizer for steelmaking. With Silicon and carbon it can deoxidize the liquid iron. And the reaction of Si, C with oxygen can provide large quantity of heat, which also helps to speed-up other allying process. Carbon of silicon recarb helps to raise C percentage, save cost for increase carbon. And, silicon recarb is dust free, there will be less slag and less air pollution. It’s very important for current manufacturers. And most importantly, it is cheap. It is also known as Silicon Carbon Alloy However, with those advantages, it is still a new type product. Not many factory can produce and not many users tried. If you are interested, welcome to contact us.
