Problems solved by technology

The following problems exist in the production of high-performance alkali-free glass fiber: 1) If a unit kiln is used for melting, the corrosion rate of the refractory material in the kiln is 5 to 10 times higher than that of zirconium corundum bricks, and the melting temperature must reach 1650°C. Requirements, the large wall of the kiln will collapse rapidly, and even cannot be produced normally due to refractory material stones; Electric melting furnace is difficult to achieve production

Embodiment Construction

[0023] In order to facilitate readers to better understand the present invention, to facilitate users to maintain and repair the products of the present invention, and to provide references for maintenance and repair researchers, mature embodiments are described below in conjunction with the accompanying drawings.

[0024] A process for producing glass with an alkali metal content of less than 0.5%, comprising the following steps in sequence: (1) burning oxygen to preheat glass raw materials to 600°C to 900°C to form a eutectic sinter; (2) electrically heating the low Eutectic sintering to above 1650°C to form molten glass; (3) electric heating to keep the temperature of molten glass above 1450°C; (4) clarification of molten glass; (5) molding of the clarified molten glass through a platinum bushing to produce glass Fibrous strands. The above step (3) can be omitted as appropriate.

[0025] The high-performance alkali-free glass furnace of the present invention includes a mel...

Abstract

The invention discloses a process and a kiln for producing high-performance alkali-free glass. The process for producing the glass is characterized by sequentially comprising the followings steps: (1), preheating a glass material to 600 DEG C-900 DEG C to form eutectic sinter; (2), heating the sinter to over 1650 DEG C to form molten glass; (3), clearing the molten glass; (4), forming glass.

Description

technical field [0001] The invention relates to a process for producing high-performance non-alkali glass fiber, basalt fiber and special new glass fiber, and a special kiln for producing high-performance non-alkali glass. The high performance generally refers to high strength and high modulus and the like. Background technique [0002] The electrical properties of glass, such as electrical conductivity, etc. are determined by the alkali metal content in the glass components. At present, the furnaces for glass production mainly include unit kilns and electric melting furnaces. Electric melting furnaces are characterized by high melting rate, simple implementation, and flexible adjustment of melting temperature. The following problems exist in the production of high-performance alkali-free glass fiber: 1) If a unit kiln is used for melting, the corrosion rate of the refractory material in the kiln is 5 to 10 times higher than that of zirconium corundum bricks, and the meltin...
