Calcium Metal wire is a deoxidizing and dephosphorizing agent for refined high-quality steel. According to the standard, calcium will be rapidly oxidized to form a thin and dense basic zinc carbonate film on the surface. Calcium fluidity is strong, copper is a purplish red glossy metal, increase the fluidity of molten steel, before touching the deposited metal calcium on the cathode, metal calcium is easy to react with oxygen in the air. Calcium Metal wire is the deoxidation and dephosphorization agent for refining high-quality steel, and the calcium core should be kept dry and in a standard state. Calcium metal for desulfurization, melting point 419.5. Its compounds can also be used as building materials.
The use of Calcium Metal wire:
Calcium Metal wire is mainly used in steelmaking, which can purify the form of steel inclusions, play a role in purifying liquid steel and partially changing the properties and forms of inclusions, improve the quality of molten steel, improve the casting state, improve the castability of molten steel, improve the service performance of steel, and significantly improve the yield of alloy, reduce alloy consumption, and reduce the cost of steelmaking. Because it is beneficial to adjust and control the content of easily oxidized elements and trace elements, it can greatly improve the yield of alloy, reduce the smelting cost, shorten the smelting time and control the composition.
Design and functional requirements of Calcium Metal wire:
(1) Using self-made pure calcium wire with specifications of 7.5-7.8mm as the core material for the core wire.
(2) Using cold rolled bright steel strip, compared to calcium iron cored wire, the thickness of the steel strip is thicker, and the pure calcium cored wire is covered. The diameter of the solid pure calcium cored wire is less than 9.5 ± 0.5mm.
(3) The cored wire has uniform wire diameter, high tensile strength, good toughness, and is not easy to break, which is more conducive to accurate control of wire feeding amount.
(4) It can be applied to steel grades refined by silicon calcium cored wire and calcium iron cored wire, and the yield of calcium can be increased by more than 52%.
(5) By using existing wire feeding equipment, deeper steel feeding depth can be achieved at lower wire feeding speeds, with easy and accurate control of wire feeding amount and stable wire feeding process.
(6) The core wire is dense and tightly wrapped, which can be stored for longer periods of time and ensure effective use.
