Q:There are various refractory materials inside many kilns such as refractory brick, what is the role of masonry of these refractory materials?
High temperature prevention, warmth keeping and heat insulation.
Q:Would you please tell me how to use the simple method to identify shale brick, clay brick?
Is the shale as raw material for high temperature baked bricks using shale and coal gangue, clay brick not dense surface, general clay brick for load-bearing structure, relatively thick, single shape; shale brick shapes, shapes with holes, in non bearing structure.
Q:How to use the firebrick to build crucible furnace? How to calculate its furnace's width and depth?
1, classify according to the smelting method : Open-hearth furnace steel: Including carbon and low-alloy steel. According to the different lining material, there are acidic and basic open hearth steel two types. Converter steel: Including carbon and low-alloy steel. According to different positions of blowing oxygen, there are bottom blowing, side blowing and BOF steel three types. Electric furnace steel: Mainly alloy steel. According to the different types of electric furnace and electric arc nail fixed Li modified cool boat to raise spending whale steel, induction furnace...
Q:What materials mix mortar to build walls (with bricks)? The more burned the harder
Refractory mortar
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: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:The stove which made of refractory bricks and fireclays will produce cracks after being used. How to solve this problem?
The use of low expansion materials will be better. But as for the stove, the appearance of crack is attributed to the selected materials or the environment. And when the temperature is not high, there still seems to be crack, so through expansion joint reservation, not allowing itself to crack
Q:What is the heating temperature in the test method of thermal shock resistance of refractory bricks
1, quenching (air cooling or water cooling), after the completion of the specified number of times. 2, maintain 20min, introduce the following types briefly. 3, repeated testing and record the times of the material produces macro cracks. The thermal shock resistance is shown by the times of thermal cycle of damaging half of the heated end face, quenching(air cooling or water cooling ) there are many expressions and testing methods of the thermal shock resistance, and then dry. Put the heating end surface of standard size brick((200~230mm) X (100~150 m K (50~100mm) claw)into the preheated to 1100 DEG C 50mm in furnace, quenching (air or water), then quenching in room temperature water for 3min, measured the maximum temperature of sample surface produces cracks. After the temperature of the material rises to a predetermined temperature, the ratio of residual anti-bending strength and anti-bending strength at room temperature before heat shock, after the material rises to various temperatures, measure its strength retention rate.
Q:What is the color of the refractory brick to repair the same color as the 1400
Smash the same brick into fine powder
Q:Expansion ratio of light corundum fireproofing brick
And then the appropriate drying, the using temperature 1500~1700 degrees of light corundum brick, the porosity is 70% to 80% Now, use foaming method to produce light corundum brick, 3g/, shaped idiosome with mould dry for 4 days in 60 degree to 70 degree oast, it will demoulding, foaming method and evaporating method produce light corundum brick, the thermal conductivity is 0. the containing of AL203 has difference, the corundum brick that use corundum hollow sphere to produce contain the highest AL203 Finished light corundum brick don't have accurate shape and size after firing.8 1, so products need mechanical or manual cutting after the kiln, finally, firing in 1300 degree and 1550 degree, basically still meters with water forming, just add to burn: 50~60h, because its production methods and the introduction of additives are different, the total sintering time.17W/, light corundum fireproofing brick can be made into density is 0, withstand voltage strength is 4MPa, the containing of A1203 is no more than 99%.
