Q:What are the grades of refractory exterior wall thermal insulation materials?: Classification of fire rating of extrior thermal insulation materials 1, According to national standard GB8624-97, the combustion performance of building materials are divided into the following grades A level: Incombustible building materials: Materials hardly burn. B1 class: Flame-retardant building materials: Flame-retardant material has good flame resistance. In case of fire in the air or at high temperature, it is difficult to catch fire and the fire will not spread quickly. And when the combustion source is removed, the burning will stop immediately. B2 Class: Combustible building materials: Combustible materials have a certain flame retardancy. In case of fire in the air or at high temperature, it will immediately burst into flames and it is easily to spread fire, such as wooden column, wooden roof truss, wooden beams and wooden stairs, etc. B3 level: Inflammable building materials: It has no flame retardant effect, and it is extremely inflammable, and the risk of fire is high. Classification of exterior wall thermal insulation materials according to fire rating: 1. Thermal insulation materials with A-level combustion performance Rock wool, glass wool, foam glass, foamed ceramic, foam cement, hole-closed perlite, etc. 2, Thermal insulation materials with B1-level combustion performance: Extruded polystyrene board (XPS) after special treatment / polyurethane (PU) after special treatment, phenolic aldehyde, gelatine powder polystyrene granule, and etc. 3. Thermal insulation materials with B2-level combustion performance: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.

Q:What are the refractories for converter?: Magnesia carbon material with large surface repair vessel, in addition to supporting the use of magnesia and magnesia cement.

Q:What are the characteristics of magnesium fireproof plate: Glass magnesium fire resistance plate is fire proof, water proof, noise insulative, heat perservative, non-toxic and tasteless, corrosion proof, easy for construction, can be sawed and nailed and have a wide range of applications as well as long service life. These advantages allow it to be widely used in construction, decoration, fire protection and be the best material to replace is to replace plywoods, MDF, particleboard, gypsum board. It is a key environmental building materials recommended by national association of construction and decoration. 1 superior fire resistance performance. 2 weather fastness, long service life. 3. light weight and anti-seismic 4 high toughness, good impact resistance and compression resistance. 5 green and environmental 6 economical 7 sound insulative and heat insulative 8 convenient for processing and easy for construction.

Q:How to divide the fire resistant level of EVB?: Inorganic materials: Level A incombustible material is mainly divided into three levels, which attributed to two types of materials! Inorganic materials: Rock wool, foam cement, vitrified micro bead, foam glass organic: Eps xps polyurethane phenolic aldehyde, polystyrene particles are divided into two manufacturing techniques including field fabrication and pre-production polyurethane - now sprayed, precast slab eps, xps, phenol - now posted, precast slab (composite board)

Q:Do you know where I can buy refractories?: Refractories are sold in following companies : Address of Huadu Refractories Co., Ltd. : NO.11 Huanjin Road, Fuyang, Hangzhou Address of Zhenxing Special Fire-Proof Material Co., Ltd. : No. 54 Pingjing Road, Yuhang District, Hangzhou Address of Zhongnai Refractories Co., Ltd.: No. 345 Fuyang, Hangzhou, Zhejiang Province

Q:Who knows the classifications of magnesia refractory?: Magnesia chrome series products: The main ingredients of magnesium chromium series are MgO and Cr2O3. Periclase is the first phase and magnesia-chrome spinel is the second phase. Products belonging to this series are magnesium chrome brick and chrome magnesia brick. The main ingredients of magnesium aluminum series are MgO and Al203. As they generate MgO and Al203, all magnesium chromium series products contain magnesia material. magnesium calcium series products The main components are MgO and CaO. They have high melting points, which are important magnesia materials. 5, magnesium silicon series products: The main component of magnesite series is SiO2, when the C / S<5, SiO2 and MgO generate MgO.Al2O3 (forsterite). From the perspective of microscopic mineral, main products of pure aluminum series include magnesium aluminum brick, periclase spinel brick, corundum spinel brick and aluminum-spinel castable in unshaped materials. I hope this answer can help you.

Q:Who knows that among refractory materials, insulation boards from which refractory material industry is superior in quality?: Using high temperature insulation material during casting process .In the molding, assembly the insulation?board on the ingot head or install heat insulation cap . There are three ways to install the molded steel insulation board and install insulation?board on at the head of the ingot, namely, clamping, nail fixation and mosaic technique.Compared with clay-based liner, the use of insulating board will improve high steel billet rate up to about 5% to 10%.

Q:What are the requirements of the performances of brasque refractory?: It is a kind of inorganic non-metallic material whose refractoriness is not lower than 1580 ℃. Refractoriness is the centigrade?temperature of refractory cone specimen wiyhout any load resisting high temperatures without melting down But only refractoriness can not fully describe the refractories, 1580 ℃ is not absolute. Refractory is now defined as material of physical and chemical properties allowing to be used in high temperature environments. Refractory is widely used in industries like metallurgy, chemical, petroleum, machinery manufacturing, silicates, power, etc., which is mostly used in the metallurgical industry, accounting for 50% to 60% of total output.

Q:What is the difference between wear-resistant material and refractory material?: One is to require wear-resistance. It can be both fire-resistant and wear-resistant, and they can enter different categories. Faced with different demands, it has a variety of features. But both can also be integrated. I think many materials have same division. One is fire-resistant. The two concepts are different division. They are not comparable.

We has been adhering to scientific and technological innovation as the company development ideas, establishing the export-oriented development strategy and has close technical cooperation with scientific research institutions.We supply many kinds of calcined bauxite.
