Q:How to judge the quality of brick, clay brick, high alumina brick furnace from the appearance?

Mainly depends on the color and density of brick. Another black clay brick and brick with iron oxide formation and how much the size of bricks

Q:Glass kiln brick for physical and chemical indicators?

Glass kiln with high quality silica brick products according to the standard JC/T615-1996, the single brick is divided into 3 grades: XBG-96, ZBG-96, DBG-96.

Q:Why is the highest brick coke oven temperature measuring point temperature not exceeding 1450

That is because the brick load softening point the maximum temperature is 1450 degrees.

Q:How much is the highest melting point of silicon?

. True density 2.35g/cm3. With acid resistance, slag erosion performance. Higher high temperature strength. The softening start temperature is 1620~1670 degrees. Long term use at high temperature without deformation. The thermal shock resistance is low (the heat exchange in water is 1~4 times). The natural silica is used as the raw material, and a proper amount of mineralizer is used to promote the transformation of quartz into quartz in the body. Slowly sintered at 1350~1430 DEG C in the reducing atmosphere. The total volume of heating to 1450 DEG about 1.5~2.2% expansion, the residual expansion will make cutting seam sealing, ensure masonry tightness and good structure strength, so that the brick load softening temperature will reach 1750 degrees Celsius above 1620 degrees in the case of the highest melting point.

Q:Why is the new trend of the high thermal conductivity of silica brick

The high thermal conductivity of silica brick all inherits the advantages of traditional coke oven silica brick, on the basis of further highlight the characteristics of high thermal conductivity.

Q:The specific content is what gb/t2608-2012 brick

Quality assessment procedures, packaging, marking, transport, storage, and quality certificates. Suitable for siliceous refractory bricks.

Q:Brick

An acid refractory consisting mainly of quartz and square quartz and a small amount of residual quartz and glass.More than 94% silica content. True density 2.35g/cm3. With acid resistance, slag erosion performance. Higher high temperature strength. The softening start temperature is 1620~1670 degrees. Long term use at high temperature without deformation. The thermal shock resistance is low (the heat exchange in water is 1~4 times). The natural silica is used as the raw material, and a proper amount of mineralizer is used to promote the transformation of quartz into quartz in the body. Slowly sintered at 1350~1430 DEG C in the reducing atmosphere. When heating up to 1450 degrees, the total volume of 1.5~2.2% expands, and the residual expansion can close the kerf and ensure the airtight and structural strength of the masonry.

Q:How to improve the thermal conductivity of the coke silicabrick rate?

To improve the thermal conductivity of silica brick for coke oven rate method:Manufacture of high density and high thermal conductivity of silica brick, adding additives such as CuO, Cu2O, TiO2, Fe2O3, (FeO), can improve the thermal conductivity of silica brick.

Q:Why in the production of the brick to detect the volume density

Density is the property of material, different density of materials, density of the same kind of material is not up to standard, affecting performance.

Q:The introduction of silica brick

The characteristics of silica brick:Brick belongs to refractory materials, with strong resistance to acid slag or acid solution erosion ability, high load softening temperature are excellent properties of silica brick, usually 1640-1680 C.The use of silica brick:Mainly used for masonry brick oven carbonization chamber, a combustion chamber and a partition wall, glass furnace and kiln roof, pool wall, high temperature hot blast furnace, glass furnace, load-bearing pool wall, hot blast stove, baking furnace of carbon bearing part of high temperature furnaces etc..
