4. If I need your offer, what information do you need?

In order to choose suitable products, it will be appreciated to provide us the information, such us specification, technical data, order quantity, products application etc.
If any question, please contact us freely.

Q: Is the diameter of 2.5 meters of the calcium aluminate powder rotary kiln referred to the inner diameter of the refractory brick?: No, it should be outer diameter.

Q: What kind of refractory brick is suitable for 24*28m rotary kiln of 5,000 tons?: 24~28 meters belongs to the transitional zone, magnesia spinel brick or silicon carbide brick (Series)

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: What refractory mortar is better if masonrying 4 meters height and 114 mm width of refractory brick: The selection of refractory mud should keep the principle of homogeneous phase with refractory bricks, that is to maintain the same material, according to the suitable temperature, choose appropriate binding agent compensation measuring forging Yao tic surprised boxing super man (phosphate, sodium silicate, or other organic combination), composite high performance admixture, it can be combined better in high temperature.

Q: What is the use of refractory bricks: Refractory bricks are mostly used as furnace lining in high temperature industry. Such as the iron and steel industry blast furnace, hot blast furnace, converter; colored reverberatory furnace

Q: What is the difference between clay brick, glazed tile and brick?: The whole brick is made of rock debris and is pressed by high pressure. After the surface is polished, the hardness can be compared with the stone, the water absorption rate is lower, and the abrasion resistance is good. The surface of the brick is not glazed, and the material of the front and the back is consistent with the color and lustre, hence the name. Although there are seepage flower, brick and other species, but relatively speaking, its color than non glazed tile. Most of the antiskid bricks are all kinds of bricks.

Q: The harm of wet bricks used in refractory bricks: Increase the natural protection time, increase the baking time, or water can not discharge, this will cause swelling deformation of furnace wall.

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: 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: 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
