Q:Which refractory is suitable for the tunnel kiln?

Shuttle kiln refractories requires the good thermal shock properties. Because the tunnel kiln is continuous firing furnace, the temperature in the kiln is long time stable and with little fluctuation. The shuttle kiln is intermittent kiln firing. The temperature in the firing kiln is adjusted by the firing curve. It is with a relatively short time and serious fluctuation. The seal and kiln car take use of the heavy corundum brick. If it is continuous kiln, the alumina hollow ball bricks are used in the burning zone. The seal of the burning zone takes use of the kiln car brick and the seal takes use of the heavy corundum brick.

Q:How to measure the influence of high-temperature performance of the products refractory in the formation of the liquid phase.

Generally how can do high-temperature performance to measure how much liquid may affect hot bending strength rul refractoriness levels of high temperature creep?

Q:The development prospect of fire-resistant material

Exported bulk material amounts to exported raw material/ To protect domestic resources, many countries have set linitations on the magnesium content in shapeless refractory material and lisences.

Q:which kind of refractory is used in golden smelting furnace? How about his using temperature

generally the price of the quartz sand refractory material is higher and the temperature can meet the requirement of 2000 degree.

Q:How much is the duration of fire resistance of the porous brick shale?

The duration of fire resistance of the porous brick shale could reach 1,580℃—1,770℃. It is predominantly applied in coke oven masonry and building, glasses, porcelains, carbon calciner, and the vault of thermal furnuces of refractory bricks as well as other load-bearing elements, and high temperature bearing parts of cowper stove. But it should be aware that it can’t be used in thermal equipment below 600℃ and with large variation of temperature.

Q:What's the classification of refractory material?

Magnesium aluminum is complex and mainly seeing what classification standard is like according to the appearance shape can be divided into two categories, setting and not setting according to the acid alkali can be divided into acidic, magnesia, high aluminum, ramming expected, spinel, spray coating, plastic, just the quality of the jade, daub material according to the chemical composition is divided into, such as clay, neutral and alkaline according to the operation mode can be divided into different castable, magnesium, calcium, magnesium chrome

Q:Can refractory be used as sealing element?

The sealing element can resist the high temperature of 1200 degree.

Q:What are the fire resistances of grc partition panels?

waterproofing: It has good water resistance; 2. fireproofing: fire resistance of partition panel≥3.5h, it has an excellent fireproof performance and can be applied to fire-proof bulkhead; 3.soundproofing: According to the different thickness of walls and surface treatments, perlite light partition panels insulation can be 40-50 decibels, to ensure that products can be used for office, commercial, entertainment and residential buildings; 4, light weight:

Q:Does the refractory material used in steelmaking all refer to refractory brick?

For example, refractory castable doesn't only refer to refractory brick, but also some bulk material and ramming?mass. Desulfurizer belongs to ferrous metallurgy auxiliary material.

Q:what is best for making refractory insulation for Blast furnace, hot stove.
