Q:The renewal of refractory brick internal the lime kiln belongs to overhaul. In the absence of production, are the replacement of valve and sporadic projects also considered overhauls? Or routine maintenance!

The replacement of refractory brick for lime kiln is definitely a major overhaul, and the replacement of the valve and sporadic items can only be regarded as routine maintenance.

Q:Do refractory bricks resist corrosion and sulfur?

There are anticorrosion and acid proof refractory bricks

Q:How are shale porous bricks and clay porous bricks distinguished?

Dimensional deviation is less than clay brickBecause the plastic index is better than that of clay shale itself, although the requirements of the national standard for the size deviation of sintered brick is the same, but the size deviation of shale in actual production is generally less than the clay brick.

Q:the refractory brick in glass furnace burner was burning, the bricks on both sides of the fire hole were burning the blocked it, what will cause brick burning?

The firebrick in glass melting furnace is mainly consisted of zircon brick, other ordinary refractory materials can not effectively prevent the erosion of glass solution. Because the glass melting liquid is eutectic mixture compared to the refractory bricks, it penetrates into the refractory brick and reduces its original performance, simply speaking, the glass melting liquid dissolves the refractory bricks as eutectic mixture .

Q:Do refractory bricks insulate heat?

It can not be generalized, generally, the insulation performance of clay is not good, but the hollow is good, such as light mullite bricks have good insulation. it depends on what kind of refractory brick

Q:Solid brick and clay brick which is expensive

Because the sintered clay brick belongs to the material which destroys the cultivated land, the national policy restricts the use and is forbidden to use the standard brick. But it can be used in the base part.

Q:What is the life of an old fashioned refractory brick kiln transformed into a flat topped tunnel kiln? what material should be used to transform the old fashioned refractory bricks vault kiln to flat tunnel kiln, and how long is the service life?

Hanger plate

Q:What is the sintering of non clay bricks?

Many kinds of brick, according to the raw materials used for clay brick, shale, coal gangue brick, fly ash brick, lime sand bricks and slag brick; according to the production process can be divided into sintered brick and non sintered brick, which can be divided into non sintered brick brick, autoclaved bricks and autoclaved brick etc.; according to whether the holes can be divided into ordinary bricks, porous brick, hollow brick.

Q:What material does tile tunnel kiln use to replace the refractory brick to have better insulation effect and save the maintenance and prolong the service life?

The price is high, but the the service life is not longer than the clay brick, some use high aluminia brick. Currently, there are no refractory products that can replace refractory bricks. The effect is good of choosing fireclay brick with high strength dense, low porosity clay brick. We have maken several lines of refractory bricks. Actually, if you choose good refractory brick, the service life will be very long. The kiln temperature is not high.

Q:What matters should be noticed when using clay refractory bricks in a glass kiln?

There are a variety of products for the production of shaped and unshaped refractory clay, such as blast furnace insulation and high alumina bricks. Brick products include refractory clay bricks, plastic materials for overload, refractory clay and high alumina casting materials, etc.. In the amorphous part, if to support the horizontal induction furnace and the straight induction furnace lining, such as refractory clay and high alumina plastic
