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: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:Is the quality of refractory brick influenced if it is soaked by water
Refractory bricks shouldn't be got wet by damp. Other refractory brick is not much problem, after touching, please wash hand, or masonry stove ignition will burst. In addition, refractory bricks containing chromium can't meet water, it's easy to hydrate and scrap, it will generate Cr VI ( chromium VI ), which is hanrmful to health and pollutes the environment, but try not to get wet
Q:Which is best of refractory brick press machine?
Rub press machine have been forced out. Without permanent magnet. The electric screw press machine is suitable for the forming of refractory bricks. Use Kehui switch reluctance to servo motor to drive electric screw press machine, have the ability of high quality electric screw press machine, no water cooling, high efficiency and energy saving, green and environmental protection.
Q:The application of wasted refractory bricks
Refine waste copper, and waste refractory bricks can be used again, shoot two hawks with one arrow
Q:should clay or refractory cement be used to lay refractory bricks?
structure strength of this brick lining is not good, apply some refractory mud, only use some virgin clay and corundum, many of the traditional approaches are very simple, mullite and carbon slurry, the specific products are selected according to the selected material and water glass or organic binder. binding agent can choose phosphate, silica and high alumina, clay is one part of the refractory clay, there are many kinds of refractory slurry according to the material, clay-based mud does use refractory cement and corrosion resistance is low
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:buliding method of refractory bricks in boilers
Q:can the refractory sand be used to make refractory bricks?
No...
