Background
Alloy is required to be added in the process of smelting molten steel, so that steel has certain characteristics or meets certain requirements. Alloys are commonly used as: deoxidizing agent: oxygen in molten steel is removed in the steel making process, and other impurities such as sulfur, nitrogen and the like in steel can be removed by certain alloys. Alloy additive: according to the component requirements of steel grades, alloy elements are added into the steel to improve the performance of the steel. Inoculant: adding into molten iron before casting to improve the crystal structure of the cast.
In the process of transporting and storing the alloy, due to the change of climate and factory conditions, partial free water is attached to the surface of the alloy and gradually forms crystal water along with the time, the crystal water exists in the form of hydrate and can be reduced into the free water under the high-temperature condition, uncontrollable influence is caused on the steel smelting process, and the quality of the steel tapping material is damaged. Therefore, before the alloy is added, drying treatment is carried out to bake and evaporate the moisture of the alloy so as to reduce the influence of element components except the alloy on the quality of molten steel.
