Q:What is the perservation method for refractory bricks used for cement kiln?
The place should be dry and ventilated. Remember that the packaging can't be damaged. If is not used for a long time, put desiccant next to the bricks. Then have thermoplastic packaging again, it won't get damp. Under normal circumstances, it can be stored for 3-5 years and won't be hairy
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:Why can earth make bricks?
Brick is a common masonry material. Brick and tile production and use in China has a long history, "Qin Zhuanhan tile". The raw material for brick making is easy to obtain, the production process is simple, the price is low, the volume of urine is in the combination, and the clay brick also has the advantages of fire protection, heat insulation, sound insulation, moisture absorption, etc..
Q:What kinds of annealing furnace refractory bricks there are?
But the energy saving effect is good, but also can use lightwight heat insulating brick, but the price is higher than that of clay brick
Q:How many squares of a ton refractory bricks?
About 2 tons , general one square clay brick is about 2 tons, from 2, one square corundum brick or magnesia bricks can reach 3 tons, it should say one square is how many tons. if it is high aluminum, then see the content of aluminum. It mainly sees what refractory bricks, because the volume and density of refractory bricks are relatively large.2 tons to 2
Q:Should refractory cement hang inner core when use carbon steel pipe make water heating hearth by self?
I think it shouldn't. There is no refractories used for circulation pipe inside the boiler, and there is how long distance between pipe and coal fire
Q:What kind of refractory material is used in the furnace when the boiler reaches more than 1200 degrees?
except refractory brick, refractories include refractory concrete (refractory cement+aggregate), fire-resistant insulating layer (refractory cement+vermiculite powder or refractory cement + diatomaceous earth) and so on.
Q:What can be applied to the burned refractory brick to resist heat shock?
Acidic refractory material use monox as the main component, among which cilica brick and clay brick are commonly used. Silica brick is silicious product containing monox more than 93%, whose raw materials include silica, waste silica brick scrap and etc. The acid resistance of slag erosion ability is good, and the softening temperature under a fixed load is high. The volume won't shrink after repeated burning, but even a slight expand; but it is vulnerable to the erosion of basic slag, and has low thermal shock resistance. The silica brick is mainly used for coke oven, glass melting furnace, acid hearth furnace and other thermal equipments. Clay brick uses refractory clay as the main raw material, containing 30% to 46% of aluminuum oxide, belong to weakly acidic refractories. It has good heat shock resistance and corrosion stability to acid slag, and it's widely used. Neutral refractory materials use aluminum oxides, chromium hemitrioxides or carbons as the main components. Corundum products containing more than 95% of alumina is a kind of high quality refractory material with wide application.
Q:What are the sizes and sizes of clay bricks?
According to the compressive strength (Newton / square millimeter, N/mm2) the size is divided into MU30, MU25, MU20, MU15, MU10, MU7.5, these 6 intensity levels.The bigger the size, the stronger the compressive strength.
Q:What are the ingredients of brick?
Artificial small bulk building, divided brick (clay brick) and non sintered brick (sand lime brick, fly ash brick etc.), commonly known as brick. Clay to clay (including shale, coal gangue powder) as the main raw material, through mud processing, molding, drying and roasting and. Chinese in the spring and Autumn period has created a square and brick, Qin and Han Dynasties brick technology and production scale, quality and variety have significant development, known as "Qin Zhuanhan tile".
