    • A glass manufacturing system and a method are described herein for reducing gaseous inclusions in high melting temperature or high strain point glasses, such as those that are used as glass substrates in flat panel display devices. In one embodiment, the method including the steps of: (a) heating a batch material within a melting vessel to form molten glass at a melting temperature TM, the molten glass comprising a multivalent oxide material; (b) heating the molten glass within a fining vessel to a fining temperature TF = TM; and (c) cooling the molten glass within a refractory tube after the first heating step or after the second heating step to a cooling temperature TC less than TM, where the molten glass remains within the refractory tube for a predetermined resident time to reduce a volume of the gaseous inclusions in the molten glass and cause gas species to migrate out of the gaseous inclusions into the molten glass such that at least a portion of the gaseous inclusions collapse into the molten glass.

    • 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 DEG C and 250 DEG 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.
