Pure calcium cored wire is a new type of steel-based ferroalloy material. It can be used as a metallurgical treatment during the process of steelmaking, particularly in order to alter the inclusion structure and improve the casting ability of molten steel. Additionally, it could also reduce the operation cost for steelmaking. It is extensively used in the de-oxidation, desulphurization and inclusion modifications of molten steel. It is superior in performance to that of the calcium silicon wire.
The calcium-rich wire is superior to silicon calcium wire due to the fact that it has a less melting point, an increased tension force and significant reduction in water loss in the course of manufacturing. This can boost steel production and quality, as well as increase the rate of calcium recovery. In the past pure calcium wire was utilized primarily to treat calcium, but it's now used in a wide range of treatment options for steel. This includes melting-steel desulphurization and oxidation, as well as inclusion modifications.
It is a low-cost, high-quality product. The product can be used as a direct method of steelmaking (BOS) as well as the arc-furnace process of remelting. During the calcium treatment process, it is directly introduced into the steel that is molten without the need for any intermediate storage or heating. This can save a lot of time, labor and energy for the calcium treatment process. It can easily be fitted onto existing equipment.
Conventional cored wire is made by wrapping cold-rolled steel strips with low carbon to the outside before by filling it up with the metal calcium powder or aluminum alloy calcium granules on the inside. There is a gap between calcium particles which causes the addition of calcium in the metal to become in no way controlled. In order to prevent the leakage of calcium as well as its oxidation the cored wire must be sealed tightly. In order to achieve this, it is necessary to hermetically seal the steel's outer sheath using the cored metal calcium wire.
The pure, solid calcium-cored wire is a special product developed by AnYang TieFa Metallurgy Co., Ltd. This is a tight-sealed device that makes it a stable calcium feed system for melting iron. The equipment is straightforward to operate and will improve the efficacy of calcium treatment during the steelmaking process. The cored wire must be inserted vertically, stably in the steel that is molten the feeding operation to avoid it reacting with air or slag. Additionally, it is essential to observe the feeding depth as well as speed in order to achieve a good reaction between the steel and the cored wire. The feeding depth of the cored wire should be about four times as deep as the normal calcium wire. This will help to make the feeding process more smooth and cut down on threading times, which will increase the effectiveness of the treatment with calcium.
