Abstract

The invention provides a magnesium smelting raw material pellet capable of improving transverse tank magnesium smelting efficiency. Raw materials of the magnesium smelting raw material pellet comprise the following components in percentage by weight: 80% of calcined dolomite powder, 5-10% of ferrosilicon powder, 2-4.8% of fluorite powder and 5.2-13% of pulverized coal, wherein the total weight of the raw materials is 100%. Calcined dolomite, ferrosilicon ores, fluorite and coal ores are used as raw materials, and are respectively ground into fine powder by virtue of a ball mill so as to ensure that the particle size of the calcined dolomite powder is less than 100 meshes, the particle size of the ferrosilicon powder is less than 200 meshes, the particle size of the fluorite powder is less than 200 meshes, and the particle size of the pulverized coal is less than 200 meshes; the obtained calcined dolomite powder, ferrosilicon powder, fluorite powder and pulverized coal are sequentially mixed uniformly, then are added into a two-roller ball press machine without adding any binding agent, and are directly pressed to obtain the magnesium smelting raw material pellet. The magnesium smelting raw material pellet provided by the invention can be used for effectively improving the magnesium recovery ratio, saving the recovery time, improving the production efficiency of the magnesium industry, reducing the cost, and providing a larger space for the development of the industry.

Description

technical field [0001] The invention belongs to the field of magnesium smelting, and relates to pellets for magnesium smelting, in particular to a magnesium smelting raw material pellet capable of improving the efficiency of magnesium smelting in a horizontal tank and a preparation method thereof. Background technique [0002] Magnesium is the third largest metal engineering material after steel and aluminum. It has many excellent properties and has a very wide application prospect. With the breakthrough of the two bottlenecks of technology and price, the global consumption of magnesium is increasing rapidly at an annual rate of 20%, which is unprecedented in the application of modern engineering metal materials. As the lightest engineering metal materials, magnesium and its alloys have a series of advantages such as light specific gravity, high specific strength, good damping and machinability, good thermal conductivity, strong electromagnetic shielding ability, good vibrat...
