Briefly talk about the role of carburizing agent in casting and the main points of use!

The key carburizer is used to make iron, forging and other manufacturing industries, accompanied by the melting of metal material liquid in the smelter, the internal carbon element has also obtained the attenuation coefficient and consumption, at this time if the relative carburization strategy is not carried out, then the production and manufacturing of goods will greatly harm the quality of goods, Carburizer is a non-ferrous metal commodity developed and designed to deal with this problem.

Sales market carburizing agent manufacturers good or bad doping manufacturers to buy difficult to choose

With the improvement of steelmaking process, carburizing agent is gradually applied by many steel mills rolling mills, carburizing agent sales market is also slowly raised temperature, now the sales market carburizing agent manufacturers are good or bad doping to promote carburizing agent purchase manufacturers in the selection of carburizing agent on the difficulty, Carburant manufacturers on the sales market are good or bad doping purchasing manufacturers difficult to choose this problem is not part of the situation is just a common shortage, how to choose a good carburant manufacturers has become the most important problem! Carburizing agent is an indispensable raw material for rolling mills and smelters. It can be seen that the effect of carburizing agent in forging is unusual. It can not only promote the flow performance of steel furnaces, but also immediately harm the quality of casting parts

Classification of carburizing agent and its production technology

Carburizing agent is divided into steel carburizing agent and cast iron carburizing agent, and some other added materials are also useful to carburizing agent, such as brake pad with additives, as friction materials. Carburizing agent belongs to the addition of steel, iron carburizing raw materials. High quality carburizing agent is an indispensable auxiliary additive in the production of high quality steel.

Carburizing agent has many kinds of raw materials, the production process is also different. It is not said that the use of graphite powder by pressing molding on the market, this production mode needs to add too much binder molding, carbon content generally can not meet the requirements of high quality carburizing agent. Pressed graphite powder, because it is a solid block, there is no porous structure, so the absorption rate and absorption rate is not as good as calcined, calcined carburizing agent. High quality carburizing agent generally refers to the carburizing agent after graphitization. Under high temperature conditions, the arrangement of carbon atoms is the microscopic form of graphite, so it is called graphitization. Graphitization can reduce the content of magazines in carburizing agent, increase the carbon content of carburizing agent and reduce the sulfur content.

Carburizing agent used in casting, can greatly increase the amount of scrap steel, reduce the amount of pig iron or do not use pig iron. At present, most of the carburizing agents are suitable for electric furnace melting, and there are a few carburizing agents with particularly fast absorption speed used in cupola. The feeding method of electric furnace smelting, should be carburizing agent with scrap and other charges together into the, small dose of addition can choose to add on the surface of hot metal. But to avoid large quantities to the molten iron feeding, in order to prevent excessive oxidation and carburization effect is not obvious and the casting carbon content is not enough. The addition of carburizing agent, according to the ratio of other raw materials and carbon content to determine. Different kinds of cast iron, according to the need to choose different models of carburizing agent. Carburizing agent characteristics itself choose pure carbon graphitization material, reduce excessive impurities in pig iron, carburizing agent selection can reduce the production cost of casting.
