Q: Does anyone know the characteristics of refractory for glass kiln?: The characteristics of refractory for glass kiln: First, it can well resist the erosion of glass?fusant and gas actor, and has sufficiently high load softening temperature and thermal stability. Usually we hope the refractories of all parts of the furnace will has no partial early erosion phenomenon to ensure that the entire furnace has a sufficiently long service life. However, due to the different mechanical, physical and chemical conditions of different parts of glass furnace, the performance of refractories should adapt to the glass furnace thereto and at the same time has no adverse effect on the adjacent other kinds of brick materials. Besides, we should consider the price of brick material, we should try to consider using commonly used stereotypes bricks of standard sizes which is cheap and quickly supplied by the warehouse. The damage of glass melting furnace lining is mainly due to chemical erosion, assisted by thermal stress. The degree and speed of chemical erosion is closely related to the applied parts, furnace temperature and melting glass varieties, and of course, the quality of the lining itself is also crucial. The nature of refractories using in the glass furnace has a very significant impact on the operation of glass melting furnace and the quality of glass. The application of poor main beam refractories will not only cause frequent shutdown for maintenance, limiting melting temperature, lowering furnace output, but also shorten the life of the furnace, and make glass has a variety of defects (stripes, stones, etc.), lower the quality of the glass. Here are the description of the nature and purpose of commonly used refractory in glass furnace.

Q: what is best for making refractory insulation for Blast furnace, hot stove.: High dimensional insulating blanket.

Q: how to use boiler fireclay: Boiler refractory, diluted with water to touch the places where needed, can be used after high temperature baking.

Q: Application of refractory materials in petroleum industry: Our natural gas transportation, chemicals, equipment, packing, safety, insulation, and even building materials are available.

Q: What refractories are used in various parts of the blast furnace.: Blast furnace from top to bottom has the throat, hearth staves, waist, bosh, hearth and furnace bottom. the specific structure is as follows: The throat is the first to be affected by the impact and abrasion, generally use high-density alumina bricks. the upper and central portion of temperature furnace is only 400 ~ 800 ℃, the area with high alumina bricks and silicate bricks. The lower part of furnace is subject to erosion and dust erosion alkali metal vapor due to high temperatures, it is required in such case to use high quality clay brick,high alumina brick,carborundum brick,corundum brick that is slag resistance and alkali?resistance, temperature resustant and wearproof. Furnace bosh temperature reached 1400 ~ 1600 ℃, serverly eroded by slag,vapor, flush. so we use carborundum brick and reaction-bonded silicon?carbide?brick. Bosh temperature reaching1600 ~ 1650 ℃, using alumina brick, corundum brick or silicon carbide brick. the temperature of Hearth near the upper portion of the outlet zone at 1700 ~ 2000 ℃, use of silicate bricks and corundum castable graphite filler, silicon carbide bricks. In 1450 Silly twitch bottom temperature sealing die of hunger slander bet phoenix astringent preserved Grade ~ 1500 ℃, use of graphite bricks and microporous carbon bricks, now use more corundum brick, corundum mullite brick and synthetic mullite brick. x26lt;P class x3d "share-btn"x26gt;

Q: What are included in fireproofing materials?: There are many types of fireproof materials, and the following listed below is the main species: All kinds of fire retardant coating such as finishing fire retardant paint, fire retardant coating components, fire-resistant coating for steel structure; all kinds of fire-proof materials such as fire?retardant material and its products, textile, fire?retardant fabric, building materials and products, flooring material and external wall thermal insulation system; all kinds of fireproofing components such as fireproof?panel, fire door, fire resistant window frame, fire resisting shutter, fireproofing glass, elevator landing door,ventilating duct, fire-proof?sealing?material and fire protection smoke exhaust fan. The main indicators to judge fire resistance are: Flame retardency, ignition,production of?toxic?gases, smoke density,heat release and exhaust gas; fire resistance, combustion performance, heat of combustion, fire-resistant performance, high temperature resistance, fire?rating, etc. There are some specific parameters which need to be judged by a professional testing equipment. You can go to the inorganic laboratory to check. The test results of fire rating are accurate.

Q: What kind of foundry ingot refractory materials are there? Please be more detailed.: This question is a little bit extensive, because there are too much foundry ingot refractory materials.

Q: Which brand of refractory fiber hard thermal insulation board is better?: Luyang ceramic fiber semi-hard board is good for it has typically applied major technological performance industrial furnaces backing, wall lining, lining material, electric heating furnace backing lining heat insulation ceramics shuttle kiln, backing lining of tunnel kilnand roller kiln.

Q: What are the main characteristics of the sic refractories?: 1. The usage temperature of silicon carbide refractory is generally 1760 ℃ 2. The silicon carbide refractories can withstand dramatic changes in temperature, and a good thermal shock resistance performance. To prevent the cracking or breaking of lining refractories. 3. Under the conditions of high or low temperature, it can withstand a certain compressive stress. 4. Under the conditions of high or low temperature, it can withstand friction. 5. It can withstand the huge hydraulic pressure or buoyancy of the metal. 6. It can also withstand the effect of furnace gases to prevent the infiltration of other refractories and reactions.

Q: What is the biggest difference between refractory bricks and clay refractory bricks? Where can I find information on the refractory bricks?: You can look up knowledge manual of refractory material to find phosphatic material, etc. Xinjiang refractory bricks, castable refractory, refractory material, silicious, corundum and alumina-magnesia: High alumina and clay refractory bricks can be divided into
