Recarburizer

Recarburizer points steelmaking recarburizer (People's Republic of China black metallurgy industry standard, YB / T 192-2001 steelmaking recarburizer) and cast iron recarburizer, and other materials may also be useful to add recarburiser , such as brake pads additive for friction materials. Recarburizer belong extra steel, iron by carbon materials. High-quality carbon additive is essential for the production of high-quality steel auxiliary additives. Recarburiser There are a variety of raw materials, production processes are different, there are a carbon-based wood, coal carbon, cokes, graphite, etc., of which there are many small species under various categories. Quality generally refers recarburizer after graphitized carbon agent, at high temperatures, carbon atoms arranged in graphite morphology was, so called graphitized. Graphite can reduce the amount of impurities in recarburiser improve recarburiser carbon content, reduced sulfur content. Recarburizer during casting use, can significantly increase the amount of scrap, or not to reduce the amount of iron. At present, most recarburizer are suitable for melting furnace, a small portion absorbed very fast recarburiser for the cupola. Furnace of feeding mode, should increase by carbon agent with the scrap charge inside put together, add a small dose can choose to add the hot metal surface. However, to avoid large quantities of iron in the water to feed, to prevent excessive oxidation occurs by carbon ineffective and casting carbon content would not be enough. Recarburiser added in an amount, based on the ratio of carbon content and other raw materials to be. Different types of cast iron, according to the needs of different types of carbon agent. Recarburizer characteristic itself choose pure carbon graphite substance, reduce iron impurities in excess, recarburiser choose the right casting production costs can be reduced.
