    摘要： The invention relates to a method for producing continuous chopped, coarse, staple inorganic fibers from such natural minerals and rocks as sand, quartz, reduced quartz sand stone and quartzite. The inventive method consists in melting silicon-based stone, which is used in the form of a raw material, at a temperature of 1750-1850° C., the melt being homogenated and stabilized at said temperature, in forming a decompression zone on the path of the melt flow to the discharge orifice die, in which the melt flow is shaped in the form of a strip with a thickness of 3-20 mm, and in passing said strip through the decompression zone at a speed V=(7 . . . 9)10−4 m/s. The air pressure in the decompression zone above the melt flow is maintained within a range of 0.10-0.30 Pa. The inventive device comprises a furnace for producing melt, a feeder, at the output of which a transfer chamber is mounted, a discharge orifice, a stream feeder assembly and a fiber producing mechanism. A homogenizer in the form of two cylinders, which are vertically and coaxially arranged with a gap one inside the other, is situated between the furnace and the feeder. A vertical baffle for producing a melt flow in the form of a strip is placed in the external cylinder. A clarifying chamber is provided with a unit for forming vacuum in the cavity thereof. Said invention makes it possible to increase the strength and chemical resistance of produced fibers by providing conditions for reducing the number of foreign, in particular, gaseous inclusions.

    摘要： A glass melting furnace with a tank and a superstructure with a furnace crown and a total internal length (“Lg”), with a preheating zone for charging material and a combustion zone with burners. A single radiation wall is located between the preheating zone and the combustion zone such that the length of the preheating zone is between 15 and 35% of the total internal length and the length of the combustion zone is between 65 and 85% of the total internal length. The preheating zone is designed for use solely with preheating of the charging material within the furnace. The oxidation gas supply contains at least 85 volume percent oxygen and at least one outlet for the waste gases from the preheating zone is connected to the atmosphere without a heat exchanger.
