- Q: does furnace use refractory cement to make refractory bricks?
- consistence Mainly concern about the strength, generally masonry mortar does not consider the degree of fire resistance
- Q: How to repair the boiler?
- use refractory bricks and plastic refractory
- Q: What is the meaning of special shaped refractory brick material n-2b?
- In fact, there are many kinds of refractory bricks, titanium, high alumina refractory brick, after drying. The mineral composition of the clay brick is mainly kaolinite (Al2O3·2SiO2·2H2O) and 6% ~ 7% impurities (K, etc.). Clay refractory bricks are iron oxide sintered by 50% soft clay and 50% hard clay clinker ingredients according to a certain granularity requirements under the high temperature of 1300 ~ 1400 degrees), perlite
- Q: How many degrees of refractory brick if its surface turns red, how to test the temperature of refractory brick after it is burnt to red.
- If the raw materials are different, then the redness is different under different temperatures.
- Q: 90 porous brick and ordinary shale brick, clay brick difference
- Porous brick is the original clay brick (now don't let in) and shale increased by a certain gap, but it is also the porosity, thickness is 90, not 53 of the original, there are also some differences in the use of solid brick and. Not for underground use.
- Q: What can be applied to the burned refractory brick to resist heat shock?
- Acidic refractory material use monox as the main component, among which cilica brick and clay brick are commonly used. Silica brick is silicious product containing monox more than 93%, whose raw materials include silica, waste silica brick scrap and etc. The acid resistance of slag erosion ability is good, and the softening temperature under a fixed load is high. The volume won't shrink after repeated burning, but even a slight expand; but it is vulnerable to the erosion of basic slag, and has low thermal shock resistance. The silica brick is mainly used for coke oven, glass melting furnace, acid hearth furnace and other thermal equipments. Clay brick uses refractory clay as the main raw material, containing 30% to 46% of aluminuum oxide, belong to weakly acidic refractories. It has good heat shock resistance and corrosion stability to acid slag, and it's widely used. Neutral refractory materials use aluminum oxides, chromium hemitrioxides or carbons as the main components. Corundum products containing more than 95% of alumina is a kind of high quality refractory material with wide application.
- Q: The difference between clay bricks and clay bricks?
- Solid bricks and porous bricks are mostly used for load-bearing structural walls. Hollow bricks are mostly used in non load bearing structures.
- 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;
