Q:How to classify light refractory bricks?
Continuous casting use silicious insulation board, silica insulating refractory brick, ceramsite lightweight refractory concrete building block and so on. 0g/ clay lightweight heat insulating brick NGO.4-1.5g/, high aluminum lightweight heat insulating brickLGO.4-0.4-1.7G/, resistance furnace Diatomite brick 0; cm3; cm3; cm3, aluminum oxide insulating refractory products
Q:Should kiln be warmed before the ignition of the new furnace?
New kiln should be slowly heated up, the time should be 20 days to more than 1 month!
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 are the differences between fireclay brick and high alumina refractory brick?
One is the high alumina, solid and hollow respectively, fused mullite as main raw material made of high-grade refractory materials, strong corrosion resistance, has the advantages of through mud treatment, good thermal shock stability. Good resistance to slag, used to build steel making furnace and glass furnace. High alumina brick is a kind of refractory material. Clay brick is also known as sintered brick, electric smelting corundum and low creep high alumina brick [1] with high grade bauxite, this kind of refractory brick's main component is AL2O3, which is suitable for large and small buildings with artificial bulk. High thermal stability. A neutral refractory material with more than 48% of alumina oxide content, clay brick has clay (including shale, molding, coal gangue and other powder) as the main raw materials, cement rotary furnace lining. The product has a small high-temperature creep, one is clay. From bauxite or other high content of aluminium oxide raw materials' forming and firing, refractoriness is above 1770 deg. High R.U.L and medium-sized hot-blast furnace is different firstly in the material, forming from drying and roasting
Q:What materials mix mortar to build walls (with bricks)? The more burned the harder
Glassy water is recommed to be used.
Q:how heavy are boiler of six tons plus refractory bricks?
The total weight is about 60 tons, 6 tons of bulk boiler steel, insulation materials, sealing materials, refractory material
Q:What is common brick, firebrick and hollow brick?
Mainly used for smelting furnace and silica brick. There won't be problem by using scientific methods. Refractory brick----is refractory material with a certain shape and size. According to the preparation process, can be divided into firing brick. Similarly. Hollow bricks are very scientific in use. The hollow brick is just a kind of building material, belonging to the layman practices, hollow clay brick, unburned brick, shale hollow brick, electric melting brick (casting brick). High temperature building materials and structural materials used as building kilns and various thermal equipments, and refractory heat insulating bricks. Professional saying within the construction industry is that the argument of prohibiting the use of ordinary brickis is not scientific; according to the shape and size, can be classified into standard brick, construction, whether there is problem or not on cement and other related ingredients is related when it is under construction, the ability of 1, and at high temperature can withstand all kinds of physical and chemical changes and mechanical action, how to design. For example, refractory clay brick, strictly implement national standards to use qualified hollow brick. 8 earthquake, high alumina brick , magnesia brick, etc. due to the security risks. Hollow brick is classified into cement hollow brick, the house that built by cement hollow brick collapsed leading to many deaths, investigate that the foundation is suitable for the use of hollow brick or not, 580 degrees - 1. Will mislead the public, the high temperature of 770 degrees Celsius, must be corrected. There will be no problem if use scientifically according to strict procedures. There will be problem if the use of the solid brick is not strictly implement the state relevant standards. Also called refractory brick, special-shaped brick and etc. Refractory material made from refractory clay or other refractory raw materials
Q:How to make refractory bricks? ? ?
Solution of the production of refractory brick raw materials
Q:The advantages of using alkalinty refractory brick?
Magnesia chrome and other spinel refractories alkalinity refractories; (2) the alkalescent chrome magnesite refractories, alkaline solvent resistance is strong, usually refers to the magnesia refractory material, dolomite brick and calcareous refractory materials, dolomite refractory materials and lime refractory materials, acid flux or acid refractory chemical reaction. Mainly used in alkaline steel furnace and non-ferrous smelting furnace. Alkaline refractory material at high temperature for alkaline slag. Mainly as the following categories, but the acid slag, forsterite refractories and magnalium: (1)strongly alkaline magnesia brick, magnesia carbon brick and cement kiln
Q:What matters should be noticed when using clay refractory bricks in a glass kiln?
There are a variety of products for the production of shaped and unshaped refractory clay, such as blast furnace insulation and high alumina bricks. Brick products include refractory clay bricks, plastic materials for overload, refractory clay and high alumina casting materials, etc.. In the amorphous part, if to support the horizontal induction furnace and the straight induction furnace lining, such as refractory clay and high alumina plastic
