The overall heat treatment is the penetration heating of the entire workpiece. Commonly used methods are annealing, normalizing, quenching and tempering....

Silicon metal is produced by smelting silica, charcoal, etc. as raw materials. The reaction equation is SiO2+2CSi+2CO. This is also the conventional method used by most suppliers of silicon metal. The silicon content of the initially obtaine...

In the smelting process, due to improper ingredients or charging, excessive decarburization and other reasons, sometimes the carbon content in the steel does not meet the expected requirements. At this time, it is necessary to add carbon to...

Influencing factors of graphite floating:Carbon equivalent,Silicon,RE,Spheroidizing and inoculation temperature,Pouring temperature,Residence time...

In order to get high quality cast iron will need high quality raw materials, there will related to several different raw materials for casting (foundry). Firstly, about the recarburizer, because of different raw materials.........

Graphite briquette were made from graphite, which with diamond, carbon 60, carbon nanotubes, graphene and so on are carbon elements of the single matter, they are each other isomorphic. Graphite because of its special structure, graphite pro...

Ductile cast iron is obtained by spheroidization and inoculation treatment to obtain spheroidal graphite, which effectively improves the mechanical properties of cast iron, especially the plasticity and toughness.........

In order to product high quality ductile cast iron, there are some problems will meet in the production, generally three types, today lets know more details about one of them shrinkage. ...

silicon carbide granule always be used for steel-making as deoxidizer, can also increase the content of silicon and carbon, the silicon carbide powder always be used for the abrasive, refractory and rubber or coating....

Ferrophosphorus has a very high value. It is manufactured by professional ferroalloy grinding machines. The quality and chemical composition of ferrophosphorus are within a certain standard range. Therefore, the effect of uniform particle s...

Ferrophosphorus for steelmaking mainly increases the content of phosphorus in molten steel, and the resulting steel has good cutting performance. The method of obtaining ferrophosphorus is mainly obtained from the phosphorus-making electric...

The use method of silicon-barium-iron alloy is the same as that of calcium, but the reaction of the barium element in silicon-barium with oxygen occurs after the reaction of calcium and oxygen. The advantage of adding barium is that the act...
