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.
But it depends on materials; for example, if clay brick is pink, it calls underburnt temperature is 700 degrees -900 degrees, paste red is called overdo temperature 1350 degrees -1390 degree, if the color turns heavier, it will be deformation. there are many reasons for refractory bricks sintering
Q:What mud is the refractory brick made of?
Firing with refractory clay, the main component is AI2O3
Q:The matching ratio of masonrying refractory bricks cement
Size of brickwork joint: Vertical and horizontal seam are 2 ~ 3 mm. The ratio of seam mud: Refractory clay mud 100%; per m3 dry, clean industrial water 400 ~ 600t/, no more than 3mm
Q:several refractory brick of rotary kiln several is damaged, how many refractory bricks should be replaced?
The life of refractory bricks in rotary kiln is generally short.
Q:is refractory brick used around the mechanism flue?
Q:Why limit sintering brick first and develop new wall material?
The common brick used in the sintering brick will be used to borrow soil from the farmland, which will lead to the degradation and abandonment of the land. The clay belongs to the cultivated land, and protects the cultivated land in order to protect the precious land resources.
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:Classification of refractory bricks
Q:What are the differences between sintered bricks and refractory bricks?
Easily weathered. There is no obvious difference in the usage between fired pavingbricks and refractory bricks; sintered bricks are generally used for residential road and landscape engineering, they do not fade; refractory bricks are used for all kinds of kiln constructions in plant: It is not anti-freeze (when the temperature is below the zero degree, the brick will easily "blister" in the saturated state), the reasons are high compressive strength and high temperature zone' heat insulation and so on. Fired pavingbrick is a powerful vacuum extrusion type. Fire suppression road brick is high temperature furnace brick, which is not suitable to be used as road brick. Its characteristics are: Wear resistance and freeze-thaw resistance (the anti freeze-thaw cycle of brick is more than 50 times in saturated state), non weathering, sidewalks, short service life. Sintered brick belongs to the building material, refractory brick belongs to the industrial kiln material, which is easy to moss
Q:What material is good of refractory bricks?
It can also be divided into a variety of kinds, it mainly depends on where it is used, each has its own advantages, neutral three categories of refractory bricks have a variety of materials
