Fireclay Insulating Bricks for Hot Blast Stove


 


Q:nan
General use clay bricks, but the silica?brick is better, the price is expensive.
Q:Are sintered brick concrete 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 fired brick, in which non fired brick can be divided into compressed brick, steam brick and autoclaved brick;With or without holes, ordinary bricks, porous bricks and hollow bricks can be divided into ordinary bricks.
Q:nan
there is no problem if it can be dismantled. And refractory brick material of every place is not the same, life is not the same. Buy some for backup , and change it once it is broken, there is no standard, the lining can be hit, as long as the induction coil can be fixed
Q:nan
The ordinary generally use clay high alumious fireclay brick. GB/T 3994-2005 insulating refractory brick. What with good material is high-grade thermal insulation refractory brick. GB/T 3995-2006, high alumina thermal insulation refractory brick , model A13, is made of aluminium oxide, A13 50U, senior heat insulatio brick B5
Q:nan
Capacitance magnesite, seawater magnesite, should be the alkaline refractory brick, magnesia-alumina spinel can absorb hydrogen fluoride, generally are magnesia brick, magnesium iron ore, forsterite, dolomite, magnesium dolomite, magnesium silica sand, magnesia-chorme spinel and magnesia chrome sand: Magnesia mineral, magnesium calcium sand, magnesite, magnesium dolomite sand, dolomite, mainly is cordierite
Q:nan
The effect of adding andalusite is better
Q:nan
Alkalinity, the production process of alkaline, acid and alkali resistant transparent instant thickening powder, you can adjust the proportion according to the cost and needs of quality, environmental protection: One: Add the preservative into water to mix, after soaking one hour, then mixing evenly the production ratio, and then add the super core release agent into water to mix, add flavor pigment masterbatch into water to mix with water mixing, ensure completely dissolved, then add the waste oil, falvor is appropriate amount= release agent. Two, the newest recipe of release agent super core release agent masterbatch, waste engine oil, water, instant acidproof and alkaliproof transparent thickening powder, wire drawing powder, preservative, flavor and pigment= release agent super core wire drawing powder with water mixing, it is the most newly developed special core masterbatch and engine oil of Chengdu Hengfeng Hongye detergent factory, and it doesn't contain toxic solvents, especially 1, it has the following features, after thickening more than half an hour or so, mix evenly is ok, in a few seconds will waste oil and alkali: 10% of waste engine oil, 20% of release agent core masterbatch, 88% of water, 500g instant acidproof alkaliproof transparent thickening powder, 80g wire drawing powder, 1g pigment and preservative and lubricating oil and industrial grease, these integrate with water.
Q:Why do some people say that clay brick insulation effect is good, and some people say that bad, in the end what is right?
Now is the best thermal insulation hollow powder briquette, because it is hollow, blocking the heat transfer, plus foam insulation on the outside, good insulation effect,
Q:Which is more useful, aerated concrete block or clay brick?
In the same basic block and brick aerated concrete price, size and clay brick is basically the same, but the aerated concrete block and more environmental protection, thermal insulation, light weight, high strength and high efficiency in construction is more prominent, so the aerated concrete block soon replace clay bricks as the main material of wall.
Q:nan
The wedge brick should contain the brick surface distortion, decrease scrap rate high temperature refractory brick is refractory with a certain shape and size, the error of symmetry and concentric reducer's size differences. The correctness of shape of the straight refractory brick should include the straight of the intersection and the distortion of brick's face. Under the premise of ensuring the service life, the key to improve the efficiency of manufacturers, and have the correct shape and precise size. This is to ensure that the product is qualified, refractory brick in addition to planning a reasonable scale, that is, the scale of the allowable error.
