Abstract

The invention relates to the production mineral wool products from basalt-bearing rock ( basalt, andesite-basalt, andesite, gabbro etc) which can be used in the building industry, in medicine, for manufacturing furniture, in chemical industry for insulating high temperature equipment. The inventive method for producing mineral wool products consists in loading a fine basalt-bearing rock in to a melting furnace, melting, cooling the melt to a temperature of production of a fiber, discharging said melt from the furnace, forming and deposing said fiber by means of the separation thereof followed by the production of the material. The basalt-bearing rock is pre-heated before it is loaded into the furnace. The melting is carried out in a bottom-electrode arc furnace fitted with carbon electrodes. Before cooling, the melt is heated to the temperature exceeding the fusion temperature and ranging between 50 °C and 250 °C in addition to being conditioned in a stabilizing chamber of the furnace in order to obtain an average composition of a glass mass and an iron melt. Afterwards, the iron melt is evacuated. The inventive production line for producing mineral wool is provided with a heat exchanger connected to the dosing mechanism and to the inside of the furnace. The melting furnace is embodied in the form of a bottom-electrode arc furnace fitted with the carbon electrodes and with the chamber stabilizing the average composition of the glass mass and mounted on the lower part of the furnace. Said stabilizing chamber is also used for cooling the melt to the temperature of production of the fibers and is fitted, in a bottom part thereof with a drawhole for evacuating the iron melt and the drawhole for melted glass mass.

The furnace’s productivity is increasing, and the consumption of fuel or electricity is decreasing. Basalt smelting is carried out in an electric furnace of a type with carbon elec- trons. As shown by the experiments, most basalts contain 1 ... 7% iron oxide less than 2 s and ... 16%> iron oxide. When smelting basalts in conventional stationary furnaces (gas or electric), a significant oxidation of iron oxide and an increase in the share of iron oxide in the alloy are produced, i.e. The ratio of 2 0 / s is significantly increased in comparison with the correlation of them in the initial stage. By adjusting the rate of oxidation of Hein in Hebrews, you can get the most out of the ordinary and better quality. In this case, the speed of oxidation is desirable to have the smallest, and the ratio is less than 0 / more than 0 is the largest.
