Q:What material is sk-34 on the refractory brick
Electric power; refractory bricks, castable refractory, building materials, chemical, glass, ferrous metals and other industries required refractory and insulation materials, all kinds of thermal insulation cotton products, thermal insulation brick, aluminous refractory cement, perlite and other unshaped refractory materials have been the best-selling products
Q:Can mud and salt be used as refractory materials
Definitely not, the refractory temperature of soil just is more than 800 degrees, it belongs to eutectic mixture
Q:Classification of refractory bricks
Q:Why is there cracks in the use of refractory bricks?
Several reasons for the emergence of cracks: (1) temperature difference stress (2) mechanical stress (3) crystal type change stress
Q:What is the relationship between the firing process and the manufacturing technique of fireclay bricks?
Q:Is the diameter of 2.5 meters of the calcium aluminate powder rotary kiln referred to the inner diameter of the refractory brick?
Perlite refractory brick is classified to outer diameter and inner diameter, pay attention to the accuracy of the size when measures, after drying, contains refractory. Our clay refractory bricks use 50% soft clay and 50% flint clay clinker, sodium to blend together according to a certain granularity requirements, after molding, etc., fireclay brick, 3373 in fact, there are many kinds of refractory bricks.
Q:is it correct that the higher the refractoriness is, the better refractory bricks are?
Not completely correct. Refractory bricks need to be strong in addition to the fire resistance.
Q:How to make the adhesion between refractory brick and the inner wall of the boiler more firm?
Professional furnaceman who can weld pins in the boiler steel plate is needed when have the bricklaying, mortar overflowing, connect with the refractory brick
Q:What is the difference between the refractory bricks, hand-made bricks and the machine pressure bricks?
Hand-made brick mainly produces brick that is not easy to produce molding Machine pressure brick adopts 100 tons of press machine to mold the density of hand-made brick is not enough, it's light; machine pressure bricks can only produce bricks that produce molding at a time, hand-made bricks mainly adopts hydraulic vibration molding machine
Q:is there any requirement for radioactive materials in refractory materials.
they all do not cause radiological hazards to the environment, so no requirements! analyze rom the element , magnesia. Do not know if it is useful, but material used by refractory materials, firstly any chemical elements are radioactive, human beings can not close, then, such as silicon dioxide: If it is radioactive. analyze from use, such as bauxite, does not have the use value
