- Q:what should press on the heat preserving cotton above the suspended ceiling refractory brick ?
- you can also put Z shaped steel on the purline, put heat preserving cotton on the roof boarding, it is easy to oprate.
- Q:Which is best of refractory brick press machine?
- Rub press machine have been forced out. Without permanent magnet. The electric screw press machine is suitable for the forming of refractory bricks. Use Kehui switch reluctance to servo motor to drive electric screw press machine, have the ability of high quality electric screw press machine, no water cooling, high efficiency and energy saving, green and environmental protection.
- Q:What is the specific heat of a refractory bricks (clay)?
- Approximately it's about 2000; M3 specific heat is wrong with this argument, two degree clay is 1730 degrees, three degree clay is 1690 degrees, clay bricks are mixture, bulk density, 1900KG/, only elementary substance has specific heat refractoriness.
- 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: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:What types of refractory bricks are divided into?
- middle rank。 A refractory is stronger than B refractory, low rank, the other is refractory, the senior is AB. Shale is hollow, it is not refractory, refractory, advanced, refractory B, there are nonfireproof materials in intermediate and low rank. Three types of refractory A
- Q:is it good to use firebricks to preserve the heat of rto furnace? Is there any other good ideas?
- Operating noise is very low, having a very strong chemical stability: The thermal conductivity is lower than 0 at normal temperature, it not only reduced the cost of the project of RTO furnace, but keeps the indoor heat dissipation heat better and reduce noise pollution. the temperature of RTO furnace surface is low after using the ceramic fiber lining to keep the heat, thereby reducing the addition of auxiliary fuel : ceramic fiber has a good thermal shock resistance: The dosage form of HLGX-589 and HLGX-312 ceramic fiber material is shown in figure RTO furnace thermal insulation material. C, good thermal shock resistance, without reserving expansion joints, ensure the lining intact, not easy to be affected by the harsh combustion atmosphere inside the RTO furnace, can deal with the temperature changes caused by periodic replacement of RTO furnace inlet. The furnace is new energy-saving furnace developped recent 30years that used for eliminating harmful exhaust gas caused by steel or paint spraying. it has long service life, high chemical stability, no heat preservation precedent for refractory bricks; B, good heat insulation effect.
- Q:What is the role of refractory brick, whether is there any books to introduce refractory bricks
- Refractory bricks are generally used to build a hearth. Such as, boiler, furnace (molten metal), air heating furnace etc, the furnace need refractory bricks to bulid.
- Q:What raw materials are used for making refractory bricks
- That is silicon aluminum refractory brick/, it can be divided into five types:thermal insulation refractory brick, alkaline series refractory brick, refractory brick containing zirconium, carbonaceous refractory brick/. Refractory bricks are divided according to the ingredient of refractory. Refractory bricks are generally made from refractory clay (kaolin) or other refractory materials.
- Q:Lining of refractory bricks in rotary furnace
- About 7000~10000 furnace in steelmaking, the level of maintenance and management of each plant is different! Refractory thinning relates to safety issues (equipment and people safety). i am not clear about zinc smelting! Zinc smelting may use rotary kiln! blow the zinc powder into the kiln.
