Q:how to test the high alumina refractory brick mixed alumina?
The first thing before producing bricks is to test whether the aluminum content reaches the standards, general testing on raw materials. Second: the shaped high aluminum brick will be tested in some professional equipment, you can know it from the professional inspection departments.
Q:What are the differences between high alumina brick and high alumina refractory brick?
High alumina brick is generally the national standard T-3 models, high alumina refractory brick is brick with more than 55% of aluminum content including special-shaped brick.
Q:why the color of refractory brick is white after high temperature firing when the meteorite is black after the burning?
There are different reasons. Meteorolites can mainly be divided into three types, iron meteorites (iron nickel alloy): Stone meteorites (the main component is silicate), and stony iron meteorites(the mixture of iron and silicate)
Q:How good is the hardness of corundum refractory brick?
The basic materials of corundum refractories are fused corundum or sintered corundum. the refractory brick containing more than 90% of Al2O3 is called corundum refractory brick. so, corundum refractory brick. Corundum has a high hardness (9 level of Mohs hardness) such as zirconium corundum refractory brick. Corundum refractory brick is resistant to acid well and melting point is also high, also known as pure alumina refractory brick products, , it has a good effect. These are closely related with the structure of the Al - 0 key, titanium corundum refractory brick, and other basic slag. It is used in high temperature oxidizing atmosphere or in reducing atmosphere. the metal and glass solution have good stability. a-Al2O3 is the main material of high temperature refractory brick and high temperature electrical insulating material .
Q:What is the refractory brick of the electric furnace?
there is no problem if it can be dismantled. And refractory brick material of every place is not the same, life is not the same. Buy some for backup , and change it once it is broken, there is no standard, the lining can be hit, as long as the induction coil can be fixed
Q:can Methanol burn refractory brick?
The upper part of the radiation chamber of the methanol oven is made of ceramic fiber, and the lower part is generally used refractory brick.
Q:can diatomite brick be used as thermal insulation refractory brick?
yes, it has good thermal insulation the raw material is cheap, diatomite brick is a kind of thermal insulation refractory brick with good performance.
Q:several refractory brick of rotary kiln several is damaged, how many refractory bricks should be replaced?
In general, if the brick inside the kiln break or loose core, the bricks of whole circle should be replaced, if only mend by replacing a damage part is also ok, but the service life is shorter.
Q:How many squares of a ton refractory bricks?
About 2 tons , general one square clay brick is about 2 tons, from 2, one square corundum brick or magnesia bricks can reach 3 tons, it should say one square is how many tons. if it is high aluminum, then see the content of aluminum. It mainly sees what refractory bricks, because the volume and density of refractory bricks are relatively large.2 tons to 2
Q:Do refractory bricks insulate heat?
Refractory bricks have a certain ability of heat insulation, but its thermal insulation is far less than that of glass fiber and wool.
