The calcium treatment in secondary refining steel is one of most important processes. This step is essential for deoxidation and desulphurisation, as well as inclusion modification. It can also increase casting rates. Injection of the calcium alloy allows for a high recovery rate and is also a cost-effective process. However, a high recovery is only possible if the filling material is completely consumed by the melt during the injection process.
In the early days of metal melting, many different methods were used. But these technologies were not without some disadvantages. Among others, they required a very high injection speed to reach the optimum depth in the ladle and, due to this, had a negative effect on the calcium recovery. The solid cored wire, developed by Anyang Huatuo Metallurgy in contrast, produces an excellent result for calcium treatment. This also results in a significant increase of the utilization of calcium.
During the production of this new type of cored wire, special attention is given to the composition of both the core and the coating. This ensures the purity of the resulting powder and improves the adhesion to the steel strip. In this way, the cored wire is extremely resistant to wear and can be used for a very long time without losing its properties. The coated core is also effective in preventing the calcium from escaping the molten metal, and therefore reducing the amount if fumes that are generated during welding.
The metallurgical benefits are therefore comparable to those achieved by conventional cored-wires but at a fractional amount of the price. The new cored-wire also emits less fumes to meet the strictest environmental regulations.
Furthermore, the new cored wire has a slag penetration capacity which is considerably better than that of conventional cored wire. The steel can now be cast with higher temperatures, and a quicker solidification. It is therefore ideal for the high-speed casters.
A new type of cored steel wire is also able to produce a very low level of oxygen in molten iron, which increases casting yields. The new wire core is perfect for applications where steel must always be free of oxides or other impurities.
