Q:How many grades of fire?rating are there for interior decoration materials?: It can be divided into construction classification and fire resistance rating. Fire prevention for buildings. Fire prevention measures should be taken in the architectural design to prevent fires and reduce fire hazards to life and property. Building fire protection includes two aspects: fire prevention before fire disaster and measures in fire disaster, among which the former is mainly to confirm the fire resistant rating and fire-resistant structure.

Q:What defect does fused cast refractories have ?: In glass production, in addition to refractory as a building material and consider its durability, we still must attach great importance to its influence on glass quality. In such cases, the impact on the quality of glass is mainly the defects that eroded down refractory materials mixed in the glass, thus being prodeced of grass products. Defects are mainly foreign body defects such as sand, knot and wave reinforcement. What may directly affect the quality of glass are the wall brick and brick kiln bottom.

Q:Who knows the classifications of magnesia refractory?: They can be devided into two major categories of fettling magnesite grain and magnesite products. They can be divided into fettling magnesite grain, magnesia?brick, magnesia-silica brick, magnesia-alumina brick, magnesium-calcium brick, magnesia-carbon brick and other varieties according to the chemical compositions and purposes Its performance is greatly affected by CaO / SiO2 ratio and impurities. The load softening point and thermal shock resistance of high purity magnesia brick are much higher than those of the general magnesia bricks. It has high refractoriness and good resistance for alkaline slag and iron slag, which is an important kind of advanced refractory material. Magnesia products are mainly produced by sintering, and sintering temperature is generally between 1500 ~ 1800 ℃. Besides, chemical binder can be added to make unburned?bricks and unshaped refractories. Mainly used in open hearth furnace, electric furnace, oxidation converter, non-ferrous metal metallurgy furnace, cement kiln and calcining kiln for basic refractory.

Q:Refractory inquiries: Neutral refractory is refractory material which is difficult to react with acid or alkaline slag at high temperature, such as carbon refractory and chrome refractory. Some of the high alumina refractories are also attributed to this category.

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:What are the requirements for the performance of refractory materials?: Electric furnace bottom and furnace slope and the wield pool should be magnesia whole knotting, magnesia carbon brick and tar magnesia brick; hot and slag line area, using high-quality magnesia-carbon brick; Brick on both sides of the furnance door should be tapping El magnesia brick, magnesite chrome brick; electric furnace cover should be high alumina brick and high alumina bricks.

Q:What are the requirements on fire resistance period of C-level fireproof glass?: What are the requirements on fire resistance period of Class C fireproof glass? The fireproof glass is a special glass which can maintain its integrity and insulation in required fire resistance tests, it can be classified into three types: Class A the fireproof glass which meet demands of fire integrity, and fire insulation at the same time. This glass has advantages of excellent transmittance, fire-proofing(smoke resistance, fire insulation, and blocking heat radiation), sound insulation and impact resistance. It can be applied to architectural ornaments, fire resistant timber doorsets with steel structure, windows, upper beam, partition walls, daylighting roofs, ceiling screens, perspective floor and other building components which need transparency and fireproofing. Class B: The fireproof glass which meets demands of fire integrity and thermal radiation intensity at the same time. This glass is mostly composite fireproof glass which has advantages of transmittance, fireproofing, and smoke resistance. Class C: The fireproof glass which only meets demand of fire integrity. This glass has advantages of transmittance, fireproofing, smoke resistance and high intensity. It can be applied to fireproof glass partition walls, fire windows and with no requirements on outdoor curtain walls, etc. The fireproof glass can be classified as composite fireproof glass and single chip fire-proof glass in terms of structure.

Q:Where is the sizing nozzle for refractories? Just enter the line, master into!: Hua Heng refractories in the industry reputation is good, especially in the Southern small steel sales are among the best!

Q:Which manufacturers have the best fire-proof materials with light weight?: Recommend Hubei Boyuejia Industrial Co., Ltd. It is a specialized high-tech enterprise that integrates research and development, production, sale and installation of new lightweight fireproof partition panel, partition panel, new partition panel and mechanical?equipment. Products are lightweight, fireproof, waterproof, sound insulation, thermal insulation, fracture resistance, anti-permeability, environmental protection, strong constitutive property (dense humidity) and other superior performances. It can be widely used in all types of lightweight wall panel of all kinds of buildings, and is one of the preferred materials of plant, residence, hotel, office building and public buildings.

Q:Does anyone know the characteristics of refractory for glass kiln?: Refractory is a kind of non-metallic material with refractoriness not less than 1580 ℃, which has better thermal shock resistance and chemical erosion resistance, low heat conductivity coefficient and low expansion coefficient. Refractoriness is the centigrade?temperature of refractory cone specimen wiyhout any load resisting high temperatures without melting down 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.
