Q:Can red bricks be burned in tunnel kiln which used to burn refractory brick?

The raw material determines the production process; the output determines the kiln type; the technology determines the quality and quantity.

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:In tunnel kiln, what is the meaning of refractory proportion 2.0?

The proportion of refractory bricks is related to the density.

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:What is the clay used to make the refractory brick?

Lining brick of teeming ladle; refractory clay used in building materials industry to produce high alumina bricks for cement kilns and glass furnaces, as well as anti sliding, high alumina lining bricks and high alumina refractory clay. The hard clay in refractory clay is used for making blast furnace refractory material, which is used in agriculture as a fertilizer promoting agent and, and electron. High alumina clay is also used in the oil well, generally does not disperse in water. In metallurgy, accounts for 2/3 of abrasive products, and so on. Hard clay and semi hard clay can be used to manufacture daily-use ceramics. High alumina clay after calcination, which has high temperature resistance! Refractory clay refers to the degree of fire resistance is greater than 1580, the hardness and proportion is relatively big, the refractoriness is good. They except has relatively high refractoriness. Such as aluminum sulfate, its dosage accounts about 70% of all the refractory materials;

Q:How to wipe off the white paint on the refractory brick (red).

Wallpaper knife should be ok

Q:The state's policy on clay bricks

Also known as clay brick brick, is a man-made small bulk building, clay brick clay (including shale, coal gangue powder) as the main raw material, through mud processing, molding, drying and roasting, solid and hollow.

Q:what is the ratio of refractory mortar and refractory bricks, such as how much refractory mortar is needed for a ton of refractory bricks?

Go to the refractory factory to buy some refractory clay that is of the same material as refractory bricks, generally boiler uses clay refractory mortar.

Q:can the red brick be used as refractory brick?

1200---1750 of the refractory bricks, below 1000 degrees of red brick brick is ok.

Q:cement concrete What kind of cement should be used to manufacture high temperature resistant Kang cement?

1, Portland cement should be. Should use aluminate cement CA625. 2, and high alumina fragment yellow sand limestone should be mixed with high temperature solution 3, add some area of reinforced steel and steel can be thin or thick, but 6mm's diameter and 50mm's spacing of steel are suggested 4, according to the situation, add CA625 about 15%, brickbat about 60% and brick powder about 25%; 5, mixing with water to cement mortar until it is slightly thicker
