Cored wire is to be adding various additives or liquid steel in liquid iron (deoxidizer, desulfurization agent, modifier, alloy etc.) broken into a certain size, and then wrapped into a composite material with arbitrary length of cold rolled low carbon steel strip.
Uses: deoxidation, desulphurization and alloying agent for steel, nodular cast iron spheroidization agent and inoculant.
Characteristic:
1.when dealing with molten iron, the reaction is smooth and uniform, so as to avoid the two oxidation;
2.Automation and precision can be realized. The composition of molten iron can be effectively controlled so as to stabilize the alloy elements in steel;
3.high absorption rate, reduce alloy consumption, thereby reducing costs, while improving the working environment.
