Q:Lining of refractory bricks in rotary furnace
The lining now is built with MgO-C brick, the specific time to change it mainly to see the quality and usage of MgO-C brick. A few years ago, the mills are desperately seeking furnace age, some can use thirty thousand furnace, by the way, furnace age of converter refers to the number of steelmaking furnace not time. So now most mills are not simply pursuit furnace age, but economic furnace age, currently furnace age of steel mills around us is mostly in about ten thousand to twenty thousand. In general, the furnace service of the converter is arranged with the overhaul of other equipment. This can realize the synchronous maintenance of various equipment. If the stove is too old but the maintenance is not timely, also is not to replace the lining brick timely, there will be leakage, then the furnace shell and even ring will be damaged, consequences are more serious . The reason is very simple for brick falling off. One is the poor quality of furnace brick,causing brick lining loose, rocking furnace will lead lining brick falling. the other one is the furnace lining brick is pressed too tight in the use procedure and the brick is too thin.
Q:Do cement kiln refractory bricks have quality guarantee period? can them still be used for a long time's pile?
They of course can be used. The plant will produce some bricks for standby application in advance, so they put for a period of time is completely no problem
Q:Do refractory bricks resist corrosion and sulfur?
The refractory brick just plays the role of resisting high temperature and insulating heat.
Q:Can lime rotary kiln refractory brick kiln be hung with klin coating?
Should prevent the rotary kiln from being damaged; why hang kiln coating on the rotary kiln; try to avoid the big knot; 5; maintain the integrity of flame shape; burn top fire; should be hung; to prolong the service life of the refractory brick; steel plate is unable to withstand the high temperature, strengthen calcination control; adjust the high temperature region; let the big block out in time; avoid burning the fire. . Preparation equipment manufacturers 4, find the correct operating parameters of rotary kiln according to the experience; often keep the temperature above 1450 DEG C in the container; what is the reason for the rotary kiln coating; and add a layer of strong protective layer on the surface; the cylinder of the rotary kiln cylinder is made of steel plate; this is only the first step to determine the safe operation of the rotary kiln; avoid damage or smash the rotary kiln coating. 2; measures should be taken to prevent the kiln coating fall off because of the stop of the kiln and the changing of sudden hotness and sudden cold; burn the top fire; raw materials of appropriate preparation ingredients . We need to know the the rotary kiln, make up in time. The fire resistance and thickness of refractory bricks are limited. 6; in the inside of the building with a layer of refractory brick. 8. Observe and adjust frequently; and can reduce the heat loss outward; control the fire; we take 8 steps to perfectly protect the rotary kiln: how to protect the kiln skin that is hung well; improve coal mouth structure; important operation method of long-term effective rate of safety energy-saving ball mill the work will be interrupted; deterioration, strengthen equipment maintenance of retary kiln, after hanging the rotary kiln skin; ensure clinker grain is fine and uniform; improve the thermal efficiency for the benefit of kiln skin sticking, must treat in time ;
Q:How aluminium oxide becomes a entity from the the form of powder (such as a ball, a stone, or a refractory brick)?
Just like the process of making steamed bun from flour. Ball milling ---in the auxiliary material to make the slurry --- suppress the body --- high temperature calcination
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:What are the hazards of solid clay bricks?
The prohibition or restriction of high energy solid clay brick production, the development of low energy consumption, thermal insulation of new wall materials, insulation performance is good, not only can save energy in production, but also can make the function of the building can be effectively improved, reducing the energy consumption in buildings in use.
Q:How are shale porous bricks and clay porous bricks distinguished?
Weathering resistance is better than clay brickDue to differences in clay shale and its performance, the national standard requires shale weathering properties than clay bricks.
Q:What are the main constituents in non clay brick sintering?
Unfired bricks are bricks used to build walls relative to sintered bricks.
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
