Application of hot repair technology of hanging zero-expansion silica bricksA domestic glass production enterprise has large fire holes on the top of the first and second lines, the top of the heat storage chamber, and the upper part of the partition wall after pourin··· ...

1. Cause analysisThe characteristics of fused zirconium corundum bricks are narrow crystallization temperature range and low thermal conductivity. Therefore, its hardening process is actually continuous.Under such continuous hardening conditions, the melt of large fus··· ...

The bottom bubbling technology is to set up one or two rows of bubbling points at the bottom of the tank between the melting zone and the clarification zone of the glass melting furnace, thereby blowing a certain pressure of gas into the kiln without destroying the no··· ...

1. Refractory material structure of the melting part of flat glass melting furnace① The bottom bricks are made of large clay bricks, arranged with vertical and horizontal straight seams, and the thickness is generally 300mm. An expansion joint is concentrated every 4··· ...

In industrial production, the masonry of electric fused zirconium corundum is a very complicated task, and in the process of masonry, it will also be classified according to different types and styles. For specific classification, please see the following introduction··· ...

The selection of refractory materials for the melting pool of horseshoe flame furnace sodium calcium (bottles, utensils, light bulbs, fluorescent lamps) glass tank furnace is as followsMelting pool:Pool wall: use temperature 1400~1600℃, select AZS-33 brick TC. Select··· ...

Sintered AZS bricks are made of zircon and alumina as the main raw materials and pre-synthesized materials as aggregates. Since the blank is a barren material, it is not effective to increase the density of the product by simply increasing the molding pressure. Increa··· ...

In glass melting furnace, in addition to the contact with flame as we mentioned before, the entire furnace pool from melting part, cooling part to forming part is in contact with high-temperature glass liquid. The temperature of glass liquid ranges from 1200-1600℃, i··· ...

Fused rebonded zirconium corundum bricks are made of AZS frit or fused AZS waste bricks as raw materials, with a small amount of kaolin or titania added as a binder. When heated to a certain temperature, the fused AZS aggregate seeps out the glass phase and forms mull··· ...

The automated production line is designed according to the process flow, which meets the requirements of automated production of equipment according to the process flow, improves product quality and production efficiency, saves a lot of manpower, and the successful op··· ...
