Problems solved by technology

The composition in the furnace must be continuously adjusted, and the adjustment time is long, the efficiency is low, and the waste is large when producing products with different composition requirements.
Moreover, it is difficult for the temperature of the melt to exceed 1500°C, the melt in the furnace cannot be stirred, and the uniformity of the composition is poor
Melting ore and other raw materials will also cause a lot of energy consumption and serious environmental pollution

Abstract

The invention discloses a preparation technology for melt for production of mineral wool, rock wool and cast stone products. The preparation technology comprises: collecting hot slag in a blast furnace or a converter, adding into an electromagnetic induction furnace; mixing with the following raw materials: basalt, quartzite, dolomite / quartz sand, and a nucleation agent; adjusting the acidity coefficient and the pH value of the slag; and heating and stirring the slag in the electromagnetic induction furnace until the fluidity, the superheat temperature and the component uniformity of the slag reach the standards, supplying the slag for a material molding apparatus by a melt flow control apparatus. According to the preparation technology, the electrothermal efficiency and the power factor of the electromagnetic induction furnace are high; raw materials and energy are subjected no extra waste; and the preparation technology helps to guarantee the product quality and improve the production efficiency and energy utilization rate.

Description

technical field [0001] The invention belongs to the technical field of inorganic material production technology. Specifically, the invention relates to a melt preparation process for the production of slag wool, rock wool and cast stone products. Background technique [0002] At present, in the production process of domestic slag wool and rock wool, most manufacturers use cupolas as melting equipment, melt basalt, slag, dolomite, etc. with coke in the cupola and supply them to fiber-forming equipment to make fibers. Melting ore and other raw materials will cause a lot of energy consumption and serious environmental pollution. [0003] The composition of the cupola furnace is controlled by the amount of charge into the furnace, and the reaction cycle is long; the control of the melt temperature and supply is adjusted by the coke ratio and the tuyere. There is a direct relationship between temperature and supply. When the temperature rises, the supply is reduced or the supply...
