Q:Is the waste of the fire resistant hazardous waste?
Can be recycled and reused.
Q:How to calculate the pressure of hydraulic machine pressures refractory brick?
If it is a plunger type cylinder, the pressure of a cylinder is the cross-sectional area of the piston multiplied by the pressure of the hydraulic system; if it is piston cylinder, that is the inner diameter of the hydraulic cylinder multiplied by the pressure of the hydraulic system. Adopt cm as diameter's unit, a unit of pressure is kilogram force per square centimeter, the calculated result is kilogram which divided by one thousand is ton.
Q:Do refractory bricks need to be sent to the lab to test after arriving the site?
Other is nothing, generally it does not need, whether single weight meets the requirements, whether the appearance is regular, usually only to see whether the size is standard, it is set in the procurement
Q:MU10 what are the non clay solid bricks?
Mu10 is the strength grade of bricks, divided into grades MU7.5, 10, 15, 20, 25, 30 and so on. Non clay brick "non sintered clay bricks, such as sand brick, shale brick, cement brick, fly ash brick etc..
Q:What are the differences between diatomite brick and ordinary refractory bricks?
The volume density of diatomite brick is 3.9 * 10-6, good compressive strength, belongs to the small outer insulation, spinel brick.
Q:Which is more useful, aerated concrete block or clay brick?
How to evaluate the porous brick right (aerated concrete block), the practicability of the clay brick, brick which is first aerated concrete block, aerated concrete block and clay brick is the coexistence of wall materials, only the current use rate than the aerated concrete block of clay solid brick.
Q:Are sintered brick concrete bricks?
Fired bricks are not concrete bricks.According to the different production process of bricks into sintered brick and non sintered brick. Sintered brick in China has more than two thousand years of history, is still a very wide range of wall materials.
Q:what is application of high alumina refractory brick?
reverberatory furnace 1, close to the neutral refractory, but because mullite crystallization has not formed the network organization, so the load softening temperature is not higher than silica brick. the refractoriness of high alumina brick is higher than fireclay brick and semi-silica brick, mainly used in blast furnace, nozzle brick,etc. it is up to 1790 C~ 1750, can resistance to acid slag and alkaline slag erosion. hot blast furnace, blast furnace, high alumina brick are widely used for producing open-hearth furnace regenerative bricks, because it contains SiO2, low impurity content, which belongs to high-grade refractory materials, electric furnace. 2, plug head used in pouring system . In addition. 3, because high aluminum products contains more Al2O3, forming less fusible vitreous body, so the high load softening temperature is higher than clay brick. because rotary kiln lining, slag resistance of high alumina refractory brick contain more Al2O3, so the ability of anti alkaline slag is weaker than anti acid slag. so it has a wide range of application. high alumina refractory brick due to the following performances
Q:Why should the clay bricks be watered first when they are building masonry walls?
Sintered clay brick because there are a lot of capillary, in the dry state water absorption ability is very strong, if you don't use water, water in the mortar will soon be sucked out of the brick, mortar workability is reduced, operation is difficult to spread the real tile.
Q:Mainly use the raw materials inside refractory bricks,
Go to the refractory factory to buy some refractory mortar that has the same texture of refractory bricks, the general boiler use clay refractory mortar.
