Use Of calcium silicon Cored Wire

Date: 04-08-2021
cored wire is the alloy cored wire,it is a composite material which is to crush various additives (deoxidizer, desulfurizer, modifier, alloy, etc) to be added into molten steel into a certain particle size, and then use a cold rolled low carbon steel strip to include it as an arbitrary length. According to the different additives, it can be divided into: silicon calcium cored wire, silicon barium calcium wore, calcium iron sire, pure calcium wire and etc.





Core-wrapping technology is a king of refining method that has been developed in recent years. It is widely used in the modern wire-feeding technology of steelmaking, the usage of cored wire is roughly as follows: Through the wire feeder, made a specified number of cored wire pass through the slag layer at a certain speed and reach the bottom of the ladle filled with molten steel, as the core of the cored wire continues to melt there, the additives wrapped in it will be continuously released into the molten steel,through the interaction of additive and the surrounding molten steel, can achieve the deodidation, desulfurization, microalloying, fine-tuning and inoculanting treatment of the treated solution outside the furnace, thereby can improve the cleanliness of the molten iron and improve the performance. Since the reaction of the additive with the molten steel is carried out in the depth of the molten steel in a certain static pressure, the oxidation and burning of the alloying elements by the air and the slag can be avoided; and can also made the additive or its vapor and treated solution have large contact area and long action time.


The alloy cored wire used for steelmaking can purify molten steel, change the shape of inclusions, improve the castability and mechanical properties of molten steel, and significantly increase the yield of ferroalloys, reduce the cost of steelmaking, and have less environmental pollution, the economic effect is remarkable.

Henan star Metallurgy Co.,Ltd.was established in 2001. The company has two 6300KW submerged arc furnaces, three modern core-conductor units, and four automatic non-floor crushing production lines. The alloy cored wire produced by our factory are in 13mm diameter and 0.4mm in the steel thickness, now has passed industrial tests in many steel enterprises in domestic, with the advantage of uniform feeding, regular geometrical size and low wire breaking rate.
