Steel industry core wires inject metal molten or add-ons in a bath of metallurgical fluid. It is particularly useful when the element being used has a lower density than liquid metal or has a higher affinity for oxygen.
The cored wire injector is a proven technology with many applications. The purification of molten metal and modifying the inclusion properties in the cast state are some of these applications. This treatment is also important in the process of oxy-combustion, which reduces the sulfur content of the iron melting. The calcium treatment has a significant impact on the castability and the carbon content of steels that are low in silicon.
There are several benefits to using a wire cored with a calcium-based core over the powdered core wires that have been used in the past.
1. It's made out of a calcium-based material with high density that is easily distinguishable from the steel. Injection mass does not evaporate in molten metal during the welding procedure.
2. It is hermetically sealed in the outer sheath. It prevents oxide inclusions in the core from contaminating the molten metal. In addition, it allows the core to enter the molten material at temperatures much lower than for conventional powdered cores.
3. This thicker sheath reduces the loss of powder during insertion. The cored wire can reach the depth of the bath that generates enough ferrostatic force to maintain the liquid calcium at the steel-making temperature.
4. It is then welded onto the strip of steel so it does not open up during the passage. The calcium passivation is not required, saving time and cost.
5. Sheaths are resistant to corrosion, and they can be used multiple times before becoming damaged or contaminated. The sheath is resistant to corrosion and can be used many times without being damaged or contaminated.
Anyang Huatuo Metallurgy Co., Ltd., which has been in business for years, can manufacture cored wires of a number of different sizes and core materials. We can supply a variety of cored wires, including the classic calcium silicate. A newer product, called Hi-Cal is also available, with a solid sheath made from pure calcium and a core containing a large amount of silicon. The sheath of this product is much stronger and more resistant to corrosion than the cored wires used in conventional steel-making. Hi-Cal has a wide range of specifications that can meet the specific needs of every steelmaker. Contact us to learn more about our services and products. Looking forward to working together!
