Q:application of phosphate refractory bricks
The 4 properties of phosphate refractory bricks: (1) high strength wear resistance (2) and chemical erosion (its alkali resistant ability is better than that of clay brick and high alumina brick) (3) and good thermal shock resistance (4) high load softening temperature in rotary kiln, kilneye, kiln Zone door cover, cooling machine and lining refractory brick falling parts easy to loose
Q:How much refractory material is required for 1 million tons of coke oven
This depends on the number of specific cubic, different factory designs different boiler, we need volume to caculate.
Q:How to classify light refractory bricks?
It should be classified based on the production materials of refractory brick! In addition to ordinary light brick (cenosphere material), mullite poly light ball, there is lightweight high aluminum brick, lightweight clay brick, diatomite brick etc.!
Q:does the furnace wall use refractory bricks to keep the heat? Or use the insulation material to keep heat ?
generally is refractory insulation materials, casting materials.
Q:can the red brick be used as refractory brick?
1200---1750 of the refractory bricks, below 1000 degrees of red brick brick is ok.
Q:What is the material of refractory brick used in the high temperature zone of the kiln?
The ordinary generally use clay high alumious fireclay brick. GB/T 3994-2005 insulating refractory brick. What with good material is high-grade thermal insulation refractory brick. GB/T 3995-2006, high alumina thermal insulation refractory brick , model A13, is made of aluminium oxide, A13 50U, senior heat insulatio brick B5
Q:How to adjust the temperature in the 160 meter tunnel kiln?
Tunnel kiln can be attemperated by burning products, this will not affect the firing of different products, and can burn back processing products.
Q:how to distinguish the quality of high alumina refractory brick when you buy it ?
see the gap between the bricks and between kiln roof and kiln wall, etc.. 6, the pressure and the volume density of Pei brick and brick Pei size, appropreate matching of high alumina powder and high aluminous aggregate and other materials, the drying and time, and the mud trapped material humidity 1. 7, to reach the requirements of production. 4, the order of loading Pei brick into kiln . should prevent the lack of a scene , the requirement , mixing time, different procedure and the order of the adding of raw materials of high alumina brick. 3, drawing plan and lack of edge of high alumina brick . 5
Q:How much fireclay is needed per cube refractory bricks?
Normal refractory bricks need to use 70-80kg refractory mud each cubic . In fact, this can be calculated, because the volume of refractory bricks and refractory mud density can be measured. Of course, here is an important point, that is the size of the brick seam, 1mm brick seam and 3mm is significantly different. Sichuan brand refractory mud has many kinds, like high aluminum, clay, corundum, magnesia, insulation and so on, the dosage is different.
Q:How many pieces of porous brick is equal to one ton?
Refractory bricks are generally classified into two types, that is, shapeless refractory materials and shaped refractory materials. Shapeless refractory material: Also known as castable refractory, is hybrid power material composed of a variety of aggregate or a kind of aggregate and one or more kinds of the mixture of adhesive particles, it should be used evenly mixed with one or more kinds of the liquid, which has strong liquidity. Shaped refractory material: The general making of firebrick, there are standard rules for the shape, can also temporarily process according to need of building and cutting. The following are the specifications. fireclay bricks 230*114*65 each block 3.0 - 3.6 kg; special-shaped fireclay brick 230*65/55*114 each block 2.8 - 3.3 kg; the reason for the weight's ranges is that because the quality is different, in general, heavy density, good quality!
