Q:how to classify Insulating Refractory ?
General materials have test reports, where fire rating is labled.
Q:How many refractory materials does the annual output of 1 million tons of coke oven require?
The production of dense synthetic Magnesium Oxide requires many steps, briefly summarized as follows:(1) Mgcl2+Ca, Mg (OH) 2, =Mg (OH) 2+CaCl2Sea salt or brine, dolomite, magnesium hydroxide, residual salt(2) Mg (OH) 2 Mg0 (low density);(3) MgO, Mgo (compact)The resulting compact Magnesium Oxide generally has a purity of up to 95%-99%, depending on the manufacturing process and the final application requirements. As shown above, Magnesium Oxide can be obtained from sea water and slaked lime. The density of the final product is through the high temperature roasting in shaft furnace and the large area obtained by calcination, and the mechanical compaction. Through the pre sintered refractory material to fundamentally eliminate the permanent contraction or extension is extremely important, it is obviously, because we cannot expect excessive contraction or extension in the use of the materials can be used to store the proper degree of molten metal or slag. The production of magnesium oxygen throughout the world (Fang Meishi) large factories in the United States, Michigan by brine well production, and by the sea water production Magnesium Oxide factory is located in Florida, Texas, California and Maryland.
Q:Does anyone know the fire endurance of steel stud partition?
The fire endurance degree is 1 hour. which is in line with the national building material fireproofing test standards. CaSo4.2H2O is molecular gypsum molecular structure formula, containing 20% ​​water, crystal water and free water, when putting on fire, 10% of the surface water will slowly evaporate, remaining10% of crystal water. It is a class A fire retardant material itself. The longest time can be 4 hours.
Q:Can anyone say something about the curtain wall fire-proof material key sealing point?
Keypoints; 1, curtain wall design must consider the safety requirements, one of which is fire protection design. 2, Generally, fire protection planning between curtain walls should use the method of setting fireproof isolation layer. 3, Two layers of fireproof isolation layer whose thickness should not be less than 100mm respectively on the top edge and lower edge of the material parts of the house. 4, the fireproof isolation layer commonly uses 1.5mm thick galvanized steel sheet as supporting plate, using for shelving fireproof sheet. The 100mm thick cavity between the layers is filled with mineral wool non-combustible materials tightly covered with tinfoil on the surfaces. 5, protective isolation layer should try to reconcile curtain wall beam level and finish floor level, so as to fill non-combustible material and to avoid that a piece of glass acrosses two fire compartments. 6, the beam should be inside 100mm thick fireproof isolation layer to protect the beam and the upper curtain wall plate. 7, when there are open fire function areas like large-scale hotel or restaurant kitchen inside the curtain walls, curtain wall glass in these parts should consider using cesium potassium fireproof glass to improve the fireproof rating in the region. 8, Fireproof setting in the around areas of curtain wall can use the same method of the above fireproof setting between layers. The joint parts of fireproof isolaton layer and main part as well as curtain wall should use fireproof sealant to seal.
Q:What kind of materials are needed to make refractory bricks?
Who knows what kind of materials are needed to make refractory bricks?
Q:Using what kind of melting aluminium furnace refractories is more appropriate?
If it's the ordinary, you can use high aluminum refractory brick with general clay, GB/T 3994-2005 clay heat insulation refractory brick. If you need these with good material, there is high alumina thermal insulation refractory brick, GB/T 3995-2006 high aluminum heat insulation refractory brick, models have A13 and material is the alumina, A13 50 u, high insulating brick B5.Intermediate insulating brick B2, etc. Dolomite brick: good hang kiln performance, good erosion resistance, but brick is usually without f - CaO, hydration, and difficult to transport and storage, less used in the production. Magnesia-chrome bricks: good hang kiln, used in calcining zone. The disadvantage is that its thermal shock resistance is poor and plus hexavalent Cr is toxic, the production and use of magnesite chrome bricks in international countries gradually reduce. Now unit using the brick find replacements as soon as possible.
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:Could you tell me the fire-resisting time of class B fire proof door?
Could you tell me the fire-resisting time of class B fire proof door?
Q:Does the external wall thermal insulation materials level b1 need the fire barrier zone?
Residential buildings should meet the following requirements: 1, The height of building is greater than or equal to 100m, the combustion performance of thermal insulation material should be level A. 2, The height of building is greater than or equal to 60m but less than 100m, the combustion performance of thermal insulation material should not be less than the level B2. When using the level B2 thermal insulation material, each layer should set a horizontal fire barrier zone. 3,The height of building is be equal or greater than 24m but less than 60m, the combustion performance of thermal insulation material should not be less than the level B2. When using level B2 thermal insulation material, each two-layer should set a horizontal fire barrier zone. 4, The height of building is less than 24m, the combustion performance of thermal insulation material should not be less than the level B2. Besides, when using level B2 thermal insulation material, each three-layer should set a horizontal fire barrier zone. According to this understanding, it can not be set.
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
