Continue ReadingThe traditional smelting method is similar to cupola smelting, which uses pig iron, recycled materials, scrap steel, ferroalloy, etc. as metal furnace materials
Continue ReadingIn order to avoid the slow melting and heating time of graphite carburizer, scrap steel and carburizer are added in batches during the batching process
Continue ReadingReduce the amount of scrap steel to reduce the amount of nitrogen brought in. In addition, increasing the carbon equivalent will also reduce the equilibrium nitrogen content.
Continue ReadingCarburizer is an indispensable additive in steel smelting. Its use can save a lot of iron ore, increase the use of scrap steel and iron, reduce production costs, and save non renewable resources.
Continue ReadingAlthough sometimes graphite powder does not form bright carbon when pouring molten iron, the wetting angle of graphite to molten iron is far greater than 90 °, that is, the sand mold is not wetted by molten iron.
Continue ReadingA certain amount of graphitized carburizing agent is added in the smelting process to improve the carbon content in molten iron and improve the mechanical properties of metal castings.
Continue ReadingThe high-quality carburizing agent determines the quality of the carburized molten iron and also affects the nucleation ability of the molten iron in the crystallization process.
Continue ReadingThere are many kinds of carburizers for steel casting (steelmaking). Generally, large steel mills will choose a variety of carburizers according to different steel types
