Abstract

The present invention discloses a glass kiln unfired magnesite brick production method, and belongs to the field of production of refractories; a glass kiln unfired magnesite brick is prepared from the following raw materials by weight: 45-50% of sintered magnesite stone, 15-20% of waste magnesite brick , 5% of iron oxide, 20% of clay, 10% of sulphite pulp and balance of water by crushing, rolling, molding, drying and other processes, the method has the advantages of use of common equipment, simple process, high production efficiency, good product quality, environmental friendliness and suitability for industrial production, and a product is mainly used for glass kiln thermal storage room checker bricks and the like.

Description

A kind of glass furnace production method not burning magnesia brick

Technical field:

The invention belongs to refractory materials production field, particularly relate to a kind of glass furnace production method not burning magnesia brick.

Background technology:

Glass is mainly made raw material with quartz sand and soda ash and is made through high temperature melting, glass furnace is exactly the equipment of fusion cast glass, glass furnace kind is more, such as tank furnace, crucible kiln etc., the most general a kind of kiln type applied in glass industry by tank furnace, it is built into by refractory brick, the damage of glass furnace kiln lining is mainly based on chemical erosion, and have the effect of thermal stresses, the degree of chemical erosion, speed and use position, kiln temperature, molten glass kind is closely related, certainly the quality of lining body itself is also most important, select glass melter refractory brick, kiln type should be considered, use position and Wear mechanism thereof, the kind of melting glass and the kind etc. of fuel, the pool wall that cell furnace contacts with glass metal and Di Deng position, pond, at present generally with containing zirconium laying fireproof bricks, in order to reduce costs, can with different laying fireproof bricks at other position of glass furnace. magnesia brick content of magnesia is more than 90%, and belonging to take periclasite as the basic refractory of principal crystalline phase, generally can be divided into sintered magnesia brick and not burn the big class of magnesia brick two, magnesia brick has higher refractoriness, good alkali resistance slag performance, loading softening starts temperature height, but thermal shock resistance is poor. not burning magnesia brick take periclasite as raw material, obtained finished product after pulverizing, batching, kneading, compression moulding, oven dry, main as regenerator chamber of glass kiln checker brick etc. China is the country that magnesium ore resources reserves enrich, and ore is fine quality, and wide shoreline and salt lake also have the fine prospect extracting magnesium oxide, and for development, magnesia fire-protecting wall provides advantageous condition. the present invention is a kind of glass furnace production method not burning magnesia brick, this device produces glass furnace with not burning magnesia brick taking pulverizer, proportioning machine, wheel roller, muller, press-forming machine, drying machine as equipment, the method have use general-purpose equipment, simple to operate, production efficiency height, good product quality, environmental protection, be applicable to suitability for industrialized production etc. series of advantages.

Summary of the invention:

The problem that the present invention mainly solves is, provide a kind of glass furnace production method not burning magnesia brick, this device is taking pulverizer, proportioning machine, wheel roller, muller, press-forming machine, drying machine as equipment, it may also be useful to raw material comprise by weight ratio: sintering magnesium stone 45-50%, useless magnesia brick 15-20%, ferric oxide 5%, clay 20%, sulfite pulp 10%, water are in right amount for raw material is to produce glass furnace with not burning magnesia brick.

The technical solution used in the present invention is:

1, the sintering magnesium stone of formula ratio, useless magnesia brick, ferric oxide, clay are sent into pulverizer and pulverized as powder, then proportioning machine is sent into, add the sulfite pulp of formula ratio and appropriate water, then by all material even blend in proportioning machine, then after all materials feeding wheel roller in proportioning machine being rolled 10-12 minute, then mixing roll is sent into.

2, the temperature in mixing roll is brought up to 135-145 DEG C, stop mixing after mixing 16-18 minute, send into press-forming machine extrusion forming with by the material in mixing roll, be down to until temperature and slough mould after normal temperature and obtain solid brick.

3. send sloughing the solid brick that mould obtains into drying machine, first adjust the temperature in drying machine to be 100-120 DEG C, after 1-1.5 hour, be adjusted to 50-60 DEG C, maintain this after temperature 1.5-2 hour drying terminate, obtain finished product after magnesia brick is progressively cooled to normal temperature.

The further technical scheme of the present invention is:

Wheel roller described in step (1) is Wet wheel roller.

Muller described in step (2) is open mixing roll, and melting temperature is 140 DEG C, and mixing time is 17 minutes.

Drying machine described in step (3) is absorption drier.

The invention has the beneficial effects as follows: provide a kind of glass furnace production method not burning magnesia brick, the method uses general-purpose equipment, have that technique is simple, production efficiency height, good product quality, environmental protection and be suitable for the advantage of suitability for industrialized production, product is mainly used as regenerator chamber of glass kiln checker brick etc.
