Abstract
This The invention of a new method for smelting silicon-aluminum alloy using ore in a submerged arc furnace belongs to the technical field of silicon-aluminum alloy smelting. The characteristic of the invention is that raw materials such as bauxite quartz stone, carbonaceous reducing agent, steel scraps, etc. are mixed evenly, and added to the submerged arc furnace as required to refine the silicon-aluminum alloy product in one go. The product contains 10-55% aluminum, Containing 10-50% silicon and 10-40% iron, it is an ideal additive for metallurgical processes such as steelmaking and thermal magnesium smelting.
Claims
The present invention is a new method for smelting silicon-aluminum alloy using ore in a submerged arc furnace. It belongs to the technical field of silicon-aluminum alloy smelting and is characterized by using bauxite or quartz. The stone, carbonaceous reducing agent, and steel scraps are crushed, screened, and weighed separately to obtain a certain proportion of the formula, and mix well before sending it to the ore furnace. The mixture is added to the furnace in a timely manner according to the changes in the furnace. After careful work by the furnace front workers, the mixture is added into the furnace. When the temperature reaches the appropriate temperature, ideal physical and chemical reactions can occur to form the required silicon-aluminum alloy.
