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:Can red bricks be burned in tunnel kiln which used to burn refractory brick?

Of course. But the temperature to burn refractory brick is very high, the average temperature is above 1500 degrees. And the temperature to burn brick is not so high, about 1200 degrees. So you should control the temperature, the tunnel kiln to burn firebrick and the tunnel kiln to burn red brick are the same, there is just a little bit difference in the materials used to build the stove!

Q:The matching ratio of masonrying refractory bricks cement

When building refractory bricks, use matching chamotte, do not use cement

Q:Where are clay bricks or cement bricks?

Cement brick is the use of fly ash, cinder, coal gangue, slag, chemical residue or natural sand, sea mud etc. (more than one or several kinds of raw materials) as the main raw material, made of cement coagulant, a kind of new wall materials by high temperature calcination made called cement brick.

Q:What are the properties of clay bricks?

Clay brick is very important. It can make clay brick not only with high refractoriness, but also can be used in many high temperature thermal equipment. The brick brick has better resistance to hot and cold, and the water cooling can reach 10~25 times at 850 centigrade. Clay brick can resist weak acid slag corrosion, the resistance to alkaline slag is slightly worse, increasing the content of Al2O3, can improve the ability of alkali resistance slag.

Q:Do refractory bricks need to be sent to the lab to test after arriving the site?

Yes, need to test physical and chemical indicators

Q:MU10 what are the non clay solid bricks?

Clay solid brick with clay and is needed by adding admixture as raw materials, solid bricks by water mixing, molding, high temperature calcination made, mainly used for masonry bearing and non bearing wall, wall materials is a kind of widely used.

Q:What types of refractory bricks are divided into?

Chimney and flue are places that high temperature gas of sulfur gathers, it should use acid material. Refractory material is divided into three major parts: acid, neutral and alkaline.

Q:What are required for high temperature refractory bricks?

good thermal shock resistance:

Q:What is light brick and what are the characteristics of light brick?

The design uses the light brick to use the solid clay brick, because the block is big, and the sound insulation effect is good, shape up through the high pressure, reducing the labor intensity! Strength of the products use high quality tabular corundum and practical mullite as aggregate, the use of air conditioning: The use of lightweight brick can increase the usable area, indoor temperature decreases by 2-3 DEG C compared to the use of solid clay brick, reduce the frame section, high alumina high strength bead brick, shorten the construction period, the economical efficiency, with sillimanite as matrix composite lightweight brick generally refers to foam brick, high temperature sintering, will not increase the weight of the floor, low iron mullite, good thermal insulation effect: Can reduce the cost of foundation. The production materials for ordinary light heat insulating refractory brick including clay, diatomite insulation refractory brick. The characteristics of light brick: 1, construction is convenient and simple. 2: The lightweight brick has good workability, saving reinforced concrete can significantly save the comprehensive cost for building, comprehensive cost can be reduced by more than 5%, at the same time, as aerated concrete has thermal insulation, in hot summer, light weight, lower power consumption, high aluminum light insulating refractory brick, improve construction efficiency, normal indoor partition is built by this kind of brick, add special additives and a small amount of rare earth oxides refining.
