The calcium metal cored wire equipment mainly wraps the calcium wire with strip steel, adopts high-frequency anhydrous welding process, undergoes fine shaping, intermediate frequency annealing, and wire take-up machine to finally produce metal calcium cored wire. This equipment can not only Coated with calcium silk, not yet coated with powdery particles. At present, our production technology has reached the international advanced level.
Core-spun wire has been widely used in modern steel-making ground feeding wire technology. It uses extra-furnace refining as a means to purify steel inclusions, improve the performance of molten steel, improve the performance of steel ground, reduce steel-making costs, and improve economic benefits. Core-spun wire The unit is mainly used to produce alloy cored wire.
There is a wide space for the development of cored wire products. Most of the various furnace materials added in iron and steel smelting can be made into cored wires, so that the variety of cored wires is very rich. However, the composition and specific gravity of various alloys are different. , The state of existence is also different, which requires different standards and production processes in terms of mixing ratio and core powder quality to meet the requirements of different steel types.
In recent years, the types of alloy cored wires produced by various domestic factories are mainly the types of furnace materials that were directly added to the ladle, such as Si-Ca alloy powder cores, titanium-iron alloy powder cores, etc. At present, we are based on the increase in steel types and the continuous improvement of metallurgical quality. To improve the needs, make full use of the feature that the powder core can be arbitrarily selected, and develop a batch of new varieties of cored wire, which are suitable for different steel types and steel manufacturers. Some varieties have passed the identification of relevant enterprise users and are used for production.
