Pure Calcium Cored Wire For Steel Making
The main reason why pure calcium cored wire is used in steel making is related to its important role in steel making. steel mills usually use pure calcium cored wire as a deoxidizer to use, mainly because in the steel making process in order to make the furnace temperature rise rapidly and maintain a certain high temperature environment, which requires the addition of oxygen, and in the late stages of steel making, too much oxygen becomes a bigger problem, will produce a large number of oxides and impurities in the steel, if not use pure calcium cored wire for deoxidation treatment, it will affect the quality of steel.
The use of pure calcium cored wire requires a matching wire feeding machine, so when purchasing pure calcium cored wire, pay attention to the specifications of the pure calcium cored wire matched by the wire feeding machine, which slowly inserts the pure calcium cored wire into the molten steel and melts it after reaching a predetermined depth. The rich calcium in the pure calcium cored wire reacts chemically with the oxygen in the steel to produce silica gas, thus reducing the residual oxygen in the molten steel. At the same time, the pure calcium cored wire can also change the form of impurities in the molten steel, making it float on the surface of the molten steel for easy handling. Overall, the use of pure calcium cored wire in steel making has effectively improved the purity of the molten steel, enabling the mills to produce many high quality grades of steel.
