Background

The information in this background section is only for enhancement of understanding of the general background of the invention and is not necessarily to be construed as an admission or any form of suggestion that this information forms the prior art that is already known to a person of ordinary skill in the art.

Rock wool is widely applied to industries such as petroleum, electric power, metallurgy and building, especially along with popularization and application of an external wall heat insulation technology, organic materials are limited to use, and rock wool heat insulation boards meet the opportunity and present a prosperous development situation. According to different raw materials, the main process of rock wool production comprises the following steps: 1) the cupola process which adopts natural rocks such as basalt and diabase as main raw materials is severely restricted in development due to the characteristics of policy and process; 2) the 'electric furnace' process which adopts natural rocks or tailings and tailings as main raw materials wastes a large amount of sensible heat of the tailings and consumes too much energy. The rear parts of the hot melting slag produced by the smelting furnace in the metallurgical industry and the high-temperature melting furnace taking the tailings as the raw materials are connected with the rock wool production line to produce the rock wool, so that the additional values of byproducts of the smelting furnace and the tailings are improved again, the sensible heat is fully utilized, and the environment-friendly rock wool production line is more and more concerned.

The hot slag rock wool production line consists of production units such as a hot melting furnace, a temperature regulating tempering furnace, rock wool and the like, a large number of continuous and discrete process variables are involved in the production flow, and the production units have more variable factors and have external variable factors such as uncertain time, temperature fluctuation, equipment conditions and the like, so that the process is very complicated. The slag is extremely easy to solidify as a bridge-hot melting slag in the production process of a series hot melting furnace and a rock wool workshop, and the reduction of the temperature drop of the hot melting slag is particularly important.

The inventor believes that as a byproduct, rock wool production lines are far away from smelting furnaces, existing hot slag transportation modes all adopt trains or automobiles, the transportation distance is too long, and therefore the hot slag is largely solidified and weighing is unstable; however, how the high-temperature melting furnace with tailings as raw materials is connected with the rock wool production line has not been reported.
