Q:How much is one ton of high alumina refractory brick?
Three high aluminum refractory brick Zhengzhou Kuwait is generally around 800. 32 years of experience, good.
Q:What refractory material does cupola lining use?
Materials defined as physical and chemical properties that allow them to be used in a high temperature environment are called refractory materials. Refractory materials are widely used in metallurgy, chemical, petroleum, machinery manufacturing, silicate, power and other industrial fields, the largest amount of metallurgical industry, accounting for 50% ~ 60% of the total output.
Q:What causes breakage of refractory bricks?
There are many factors that lead to the damage of refractory brick, can be divided into: the chemical loss (e.g. salt penetration, redox phenomenon), heat loss (burning, thermal shock), mechanical loss (kiln deformation, thrust, brick masonry quality etc.).
Q:Which is better, the soft core or the hard core?
The use of each of the single core copper wire with low line, 1.5 square with cap line home, socket 2.5 square, air conditioning to walk alone line 4 square can, when the terminal box into a socket with leakage protection switch, prevent overload and short circuit.
Q:What does refractory consist of
According to the chemical characteristics of refractory raw materials can be divided into acidic refractory materials, such as silica, zircon etc.; neutral refractory raw material, such as corundum, bauxite, mullite (acidic) (acidic), Ge (alkaline) iron and graphite; alkaline refractory materials, such as magnesite, dolomite, magnesium sand calcium sand.
Q:How to reduce the harm caused by two times mullite in high alumina refractory material
Two times mullite refers to the content of aluminum is about 70%, in high temperature sintering, the expansion coefficient is large, the thermal expansion rate is high.
Q:Which is faster for heat transfer between corundum bricks or high alumina bricks?
75 high aluminum and 43 clay bricks, 75 single weight 4.5kg or more. 43 3.65kg or so, the use of temperature 75, high aluminum in about 1520, 43 of brick 1430 or so, the color of 75 pan white, 43 of the Loess color. In short, the difference is great.
Q:What are the requirements for Rubble backfill height?
Backfill should be filled with large stones, big face, small face upward, the decoration is stable, and then use small stones leveling, the gap between the stones can be swept into the slag, gravel, so that the gap filled.
Q:The difference between ordinary and diatomite brick refractory brick
To say the difference, the material is the biggest difference. There are diatomite brick density, compressive strength of small brick kiln belongs to the outer thermal insulation, and heavy refractory brick kilns for multi village in direct contact with the flame, high temperature resistance, good compressive strength, but no insulation. Hope to help you.
Q:Use of high alumina refractory bricks?
High alumina brick refractory than clay refractory bricks and brick refractory degree are higher, up to 1750~1790 DEG C, which belongs to high-grade refractory materials.
