Pure Calcium Wire for Sale
Use self-made ￠7.0-￠7.8mm pure calcium wire as the core material of the cored wire.
Using cold-rolled steel strip, the strip thickness is more reasonable, diameter ∮9-10mm, uniform wire diameter, high tensile strength, good toughness, not easy to break, etc., which is more conducive to accurate control of wire feeding.
This product can be applied to steel grades refined by calcium-iron cored wire and silicon- calcium cored wire, and the yield of calcium is increased by more than 50%.
Using the existing wire feeding equipment, a deeper feeding depth of molten steel can be achieved at a lower wire feeding speed, the amount of wire feeding is easy to accurately control, and the wire feeding process is stable.
The core wire is dense and tightly wrapped, which can be stored for a longer period of time and can also guarantee the use effect.
The Specification of Solid Calcium Cored Wire
|Product||Ca||Calcium wire weight|
|Calcium cored wire||98%||60-70 g/m|
Advantages of solid calcium metal cored wire:
1) The recovery rate of calcium element is increased. After feeding the solid core pure calcium cored wire developed by our factory, the average recovery rate of calcium for low-carbon and low-silicon steel represented by SPHC reaches more than 15%, and the use efficiency of calcium Compared with calcium-silicon cored wire, it is about 52% higher.
2) Cost reduction is obvious. The feeding weight of solid pure calcium cored wire per ton of steel is only about 38% of that of silicon calcium cored wire.
3) It is more conducive to the production of pure steel.
4) Reduce and eliminate nozzle blockage of continuous casting steel.
5) Reduced work intensity.
The Production Process of Calcium Wire
Pure Calcium Wire Development
Pure calcium wire (Solid metal calcium cored wire) solid pure calcium core wire was used by foreign steel mills for the treatment of molten steel in the 1970s. So far it has been widely used in the world, especially in the rise and rapid development of thin plate continuous casting technology in the 1990s, the advantages of solid pure calcium core wire have been recognized by most famous steel mills. At present, the market share of solid pure calcium core wire in North America has exceeded 70%, and the European market has reached 40%. In recent years, many steel mills have imported solid pure calcium core wire in my country, and achieved good economic and social benefits. .
The cored wire can be more conveniently put metallurgical materials into the molten steel during the steelmaking process of the manufacturer. The method of use is to insert the cored wire vertically into the molten iron or steel through the wire feeding machine of the manufacturer. The metallurgical materials such as the cored wire will be fully melted and chemically reacted, effectively avoiding the reaction of the added elements with air and slag, and improving the absorption rate of the manufacturer’s metallurgical materials. The cored wire also has the functions of refining and precision casting to change inclusions, alloy and purify molten steel, which has a significant effect on manufacturers to improve the quality of cast iron and cast steel, reduce the cost of casting steelmaking, and improve the economic benefits of cast iron and cast steel.
