Welcome to visit our factory.
- 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.
- Q: Should kiln be warmed before the ignition of the new furnace?
- If you don't have to heat up the furnace. The new furnace must be heated up, and the temperature should be increased according to the heating-up furnace curve, so the current situation you meet is appeared
- Q: Where the refractory bricks rider bricks that are used for building arch and vault should be put?
- Arch and vault shall be built simultaneously from both sides of the arch of the foot to the center of symmetry, when masonry, inverting concentric reducer of arch brick is prohibited; the lock should be driven into the brick arch from the side, if the last rider brick can't be driven from the side, you can process the first 1-2 brick to make the size of the lock and the lock buckle equal, and then drive suitable rider brick from top, and use steel plate to jam-pack the side; dismantling arch tire must be performed after all rider bricks are driven and lock brick arch foot ditch masonry is completed and the final tightening nut for skeleton retractor rear.
- Q: Do refractory bricks need to be sent to the lab to test after arriving the site?
- Generally speaking, as long as the use of temperature is not higher than 1500 degrees, it is not required to do the test, even if the ordinary refractory brick temperature is about 1500. If the temperature is high, then you do test to determine what kind of texture of refractory brick you need
- Q: What is the sintering of non clay bricks?
- Unfired bricks are bricks used to build walls relative to sintered bricks.
- 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: What are the type, location and the physical and chemical effects of the refractory brick used in the cement rotary kiln?
- But most people use high alumina brick or clay brick, G6 refractory brick. The specific masonry location, such as G4 refractory brick, standard brick, T38, OD, T39, according to the length of your rotary kiln, many kinds of refractory bricks are used in cement rotary kiln, the specific size of the inner diameter should be calculated in detail
- Q: How to count the number of loading refractory bricks?
- Use one meter by one meter wooden raft-towing: use one meter raft-towing to count: Known your brick is T-3 standard bricks, each four layers lies down 15 and sidewards is 4 =64; according to 3.4kg, 47 clay bricks can hold 10 to 12 layers. According to the upper limit, each raft-towing can hold 2.3 tons
- Q: Blend 12% fireclay and 88% refractory cement. Moderate water and mud are used to pile up firebricks?
- Refractory bricks can irectly be liner. Lightweight mullite brick can be used for relatively longer time. If there is no mullite brick, use mud said above for some time, then continue to use by patching up.
- Q: What is the clay used to make the refractory brick?
- Lining brick of teeming ladle; refractory clay used in building materials industry to produce high alumina bricks for cement kilns and glass furnaces, as well as anti sliding, high alumina lining bricks and high alumina refractory clay. The hard clay in refractory clay is used for making blast furnace refractory material, which is used in agriculture as a fertilizer promoting agent and, and electron. High alumina clay is also used in the oil well, generally does not disperse in water. In metallurgy, accounts for 2/3 of abrasive products, and so on. Hard clay and semi hard clay can be used to manufacture daily-use ceramics. High alumina clay after calcination, which has high temperature resistance! Refractory clay refers to the degree of fire resistance is greater than 1580, the hardness and proportion is relatively big, the refractoriness is good. They except has relatively high refractoriness. Such as aluminum sulfate, its dosage accounts about 70% of all the refractory materials;
