Effect of adding method and time of Carburizing Agent on Foundry smelting


Graphitized petroleum coke factory

Carburizing agent plays an important role in foundry smelting. Carburizing agent has stable chemical properties, high thermal conductivity, low thermal expansion coefficient and good wear resistance, which can greatly increase the amount of scrap steel, reduce the amount of pig iron or not. 

The addition of carburizing agent in casting smelting has great influence, and the adding time and method of carburizing agent also have influence on casting smelting. 

Effect of adding method of Carburizing Agent on Foundry smelting. 

Dispersion addition method: according to the ratio or carbon content requirements, with the furnace charge added to the lower part of the electric furnace, a layer of metal charge, a layer of carburizer, carburizer melting without slag. 

Centralized addition method: the furnace charge only melts part, in the case of melting molten iron temperature is low, all the carburizing agent is added to the molten iron at one time, and the solid charge is pressed into the molten iron at the same time. 

In-package inkjet toner: inkjet toner carburizer, generally using nitrogen as carrier, but under industrial production conditions, CO, chemical reaction heat produced by oxygen combustion in compressed air can partially compensate for cooling. 

Moreover, the reduction atmosphere of CO is beneficial to improve the carburization effect.

When tapping, add: the particle size of 0.5-1mm carburizer is put into the bag or rushed in with the current from the iron trough, and the molten iron is fully stirred after it is out of the molten iron. 

Carburizing agent is generally packed in woven bags or paper bags, storage must be moisture-proof.
