- Q: Do you know the refractories?
- Alkaline material products: MgO, CaO based crystalline phase, because MgO and CaO are alkaline earth oxides, so it is called alkaline refractory. Their high melting point, alkali resistance slag (C/S > 2) corrosion ability is strong, belong to advanced refractory materials, but they are easy to hydration. Magnesia chrome brick, dolomite brick, brick olive and other products, the main chemical composition is MgO, CaO China also belongs to alkaline materials.
- Q: What is the fire endurance of ceramsite concrete blocks?
- The fire endurance of 240mm thick ceramsite concrete blocks is 2.9 hours. It is made by adding pottery into fine aggregate, using cement as binding material, by mechanical mixing, molding machinery and natural protection. Ceramsite building blocks are used as wall material, which can reduce workers' labour intensity. It saves work and material. There is no empty drum during rendering. It is not easy to produce fissure. It has sound insulation, good thermal insulation performance, and is convenient to decorate. Nails, expaned setscrew and no wood anvil can be directly hit into wall. Moreover, It has high firmness.
- Q: What is the function of refractory material?
- Refractory is a basic material in the field of high temperature technology. Generally, the refractory is used as structural material or lining to resist high temperature in various thermal equipment and high temperature container. In the iron and steel industry and metallurgy industry, coke ovens are mainly composed of refractory materials. Various refractories that meet the requirements are essential in blast furnace for ironmaking, hot stove, all kinds of steel-making furnaces, soaking furnace and heating furnace. Not only the die casting for molten steel needs lots of refractory materials, but also the continuous casting needs some high-quality refractory materials. Without high-quality refractory materials, external refining is also not impossible to achieve. Statistics show that the steel industry is the sector that needs the most refractory. Pyrometallurgy and thermal processing of ferrous metal also needs refractories. All high-temperature furnaces or lining in construction materials industry or other high temperature industries that produce silicate products such as glass industry, cement industry, and ceramics industry must be constructed with refractory materials. All kinds of roasting funaces, sintering funaces, heating furnaces, boilers, flues, chimneys and protective layers in chemical, power and machinery manufacturing industry need refractories. In short, when some kind of structures, devices, equipments or vessels are used under high temperature, they all should utilize refractory to resist the high temperature because those materials will deform, soften and fuse or will be eroded, scoured or broken due to the physical, chemical, mechanical effects, which may stop the operation, affect the production, contaminate processed objects and impact the quality of products.
- Q: What are the specifications of fire resistant bag?
- Mesh number, namely hole number, refers to the hold number in each square inch. 5o mesh refers to 50 holes in each square inch and 500 mesh 500 holes. The larger the mesh number is, the more the holes are. The larger the mesh number is, the smaller the hole aperture is. Generally speaking, mesh number× aperture (microns) = 15000. For example, the aperture of a sieve of 400 mesh is about 38 microns; the aperture of a sieve of 500 mesh is about 30 microns.
- 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: Can refractory be used as sealing element?
- It can. For example, fiber ceramics can resist high temperature! !
- Q: Does anyone know fire-proof material of fireproof wooden door?
- Fireproof wooden door goes through the flame treatment, so it can prevent fire. Its principle: Fire-retardant treated timber has become flame retardant material itself and its fire endurance has increased. The commonly used method of fire retardant treatment for timber including: Spraying method, soaking method, boiling method, vacuum method, vacuum-pressure method. Spraying method and soaking method are generally used for timber surfaces which are no longer going through planing process, and thin plate fire retardant treatment, whose thickness is less than 10mm .
- Q: What thickness is needed of the ultra-thin fireproof paint with a fireproof time of 2.5 hours?
- There are two kinds: 1, the thickness of the plate is between 20 ~ 50 mm with composite structure 2, sheet thickness is between 6 ~ 15 mm calcium silicate fire prevention board.
- Q: Does anyone know what is the use of waste refractory materials?
- 1.Waste refractory bricks can be reused to make the refractory bricks after being crushed by crusher, but the price is not very high. The purchasing price of refractory plant is ?60/ton. Because the refractory material has been calcinated for two times, it becomes easier to make bricks expansion coefficient with waste refractory bricks, but too much is inadvisable. If too much, the refractory materials would have a bad combination, which will give rise to loose bricks and incomplete corners. Nowadays, ordinary refractory plants would purchase waste refractory bricks to produce bricks, but better plants wouldn’t do this.
- Q: Why the corundum can be used as refractory
- Corundum has high refractoriness, so its high temperature performance is very good.
