Rare earth ferrosilicon is in the form of a block, has a metallic luster, is hard and brittle, and is easily crushed. The rare earth ferrosilicon alloy is silvery gray. The rare earth silicon iron magnesium alloy flashes a blue luster in a silver-gray matrix.
Rare earth ferrosilicon alloys are very effective as denaturants in steel. China is one of the earliest areas for the development, production and application of rare earth ferrosilicon. However, a single electrothermal method has been used to this day. The total energy consumption of the method is relatively high; in the smelting process, in order to shape good reducing conditions, it is necessary to add a large amount of lime slag and adjust the alkalinity of the slag. The amount of smelting slag is relatively large, and the yield of rare earth is low; the content of Ca and A1 in the product is high. In foreign countries, rare earth iron alloys and alkaline earth iron alloys are basically smelted by the carbon thermal method. This method can greatly reduce the cost of the product by utilizing cheap ore raw materials and directly preparing the alloy in a large-capacity submerged arc furnace. However, it is usually encountered due to the formation of slag or carbide furnace in the furnace. Difficulties. This has led to a serious deterioration in the quality of the alloy and the technical and economic indicators of all production. Our country has also made useful attempts.
