calcium iron cored wire

Coat the calcium metal individually to make a cored wire to become a pure calcium wire, mixed calcium metal with a certain proportion of iron powder to become calcium iron cored wire. At present, the domestic and foreign steel companies are main use calcium iron cored wire for calcium treatment for low carbon, ultra low carbon, low silicon steel and pure steel with strict requirements on appearance and quantity of inclusions.

The use of calcium iron cored wire for calcium treatment is an efficient and final refining technology. It can meet the purposes of deoxidizing and desulfurizing molten steel, changing the shape of inclusions, promoting the floating of inclusions, purifying molten steel, and improving the cast-ability of molten steel. In addition, it also does not increase the content of silicon in molten steel. At the same time, it has outstanding advantages in terms of stable production operations, improving product quality, reducing production costs, improving economic efficiency and environmental protection.

Following is functional requirements of calcium iron cored wire:

(1)The cored wire has good process performance, the requirement of using high-speed wire feeding,continuous wire, not entangled.

(2)It plays the role of deoxidation, desulfurization and de-inclusion, and after treatment, the silicon, hydrogen and nitrogen content of molten steel does not increase.

(3)It can stably control the content of aluminum and sulfur in steel, modify the inclusions, improve the mechanical properties of steel, and significantly improve the transverse impact toughness, plasticity and hot work-ability of steel.

(4)The recovery rate of alloy elements is improved and stable, and the recovery rate of calcium is 12%~19%.

(5) Reducing the clogging of the nozzle, which is beneficial for continuous casting.

(6)Small temperature loss of molten steel.

 

Huatuo has in the calcium iron cored wire for more than 10 years, now owned five production lines of cored wire, three lines for powder wrapped such as calcium silicon cored wire, calcium iron cored wire, carbon cored wire,ferro silicon magnesium cored wire etc, and two lines for solid cored wire such as solid calcium, can accept custom diameter of 13mm or 9mm, trustful cored wire manufacturer waiting for your contact.
