Nice Performance Material CaFe Cored Wire

CaFe cored wire is made of a mixture of 25-35% metallic calcium particles and the rest of iron powder as the core material and then covered with strip steel. This structure allows the cafe cored wire to be easily added during the steelmaking process and play its unique role. CaFe cored wire can effectively deoxidize and desulfurize during the steelmaking process, improving the purity of molten steel. By adding cafe cored wire, the shape of inclusions in the molten steel can be changed, and the floating and removal of inclusions can be promoted, thereby purifying the molten steel. The use of cafe cored wire can significantly improve the pourability of molten steel, reduce problems such as nozzle nodules during continuous casting, and improve the overall quality of molten steel.

The production process of cafe cored wire requires strict control of factors such as the quality of raw materials, the particle size of powders, and the thickness of steel strips to ensure the stability and consistency of the product. During the production process, some advanced manufacturers use automated production lines and precision batching and feeding systems to improve the accuracy and efficiency of the product. During the steelmaking process, the cafe cored wire is inserted into the molten steel through professional wire feeding equipment. When the cored wire skin is dissolved, the calcium iron alloy powder inside dissolves deep in the molten steel and reacts chemically with the molten steel to play its role in deoxidation, desulfurization and changing the morphology of inclusions.

With the development of the steelmaking industry and the improvement of the quality requirements for steel products, the market demand for cafe cored wire as an efficient refining technology continues to grow. Domestic and foreign steel companies generally use cafe cored wire when calcium treating low-carbon, ultra-low-carbon, low-silicon steels and pure steels with strict requirements on the morphology and quantity of inclusions. In addition, with the continuous advancement of technology and the continuous expansion of the market, the application prospects of cafe cored wire in the steelmaking industry will be broader. 

In the production process of cafe cored wire, the quality and technical requirements of each link need to be strictly controlled. For example, the process performance of the cored wire should be good, and meet the requirements of high-speed wire feeding, no wire breakage and no winding; the content of silicon, hydrogen and nitrogen should not increase; the Als content in the steel can be stably controlled, the inclusions are denatured, and the mechanical properties of the steel can be improved. In addition, the purity of metal calcium particles is also one of the important factors affecting the quality of cafe cored wire, so it is necessary to use accurate and reliable measurement methods for detection and control.
