High Temperature Castable Refractory Cement

 

 

 

Product Description

            Refractoriness of not less than 1580 °C cement. According to the composition of different can be divided into low calcium aluminate refractory cement, calcium aluminate cement, calcium aluminate cement and dolomite refractory cement. It can be used for various refractory cement cement refractory aggregate (such as corundum, Calcined Bauxite,etc.) made of refractory mortar or concrete, used in cement rotary kiln and other industrial furnace lining.

 

 

Specifications

 

 

Refractory cement lining baking, must pay attention to the following matters:

1) at room temperature 350 degrees, most likely caused by local spalling, special attention should be paid to slow baked. As in the 350 degree heat preservation is still a lot of steam coming out, still should slow heating rate.

 

2) in poor ventilation, water is not easy to discharge conditions, to extend the preservation time.

 

3) when using heavy oil for baking, to prevent oil spray on the lining surface, to prevent local burst.

 

4) when using firewood baked, direct contact with the flame is often caused by local heating too fast, should be protected.

 

5) on refractory cement pouring, at least by 3D after baking.

 

6) for refractory cement lining cooling slowly, avoid the forced ventilation.

Q: What kind of material is good for cabinet fireproof board
What kind of material is good for cabinet fireproof board What are the advantages and disadvantages of using it? How much is the price? A about how much does one piece cost?
Q: What are the characteristics of magnesium fireproof plate
Plate glass magnesium fire with high temperatures, flame retardant, sound absorption, shock-proof, pest control, anti-corrosion, non-toxic tasteless non-polluting, can be used directly on the painting, direct veneers, available gas nail directly on the tile, the surface has good coloring , high strength, resistance to bending toughness, nails, saw, can be sticky, easy decoration. It can also be made into thermal insulation materials with a variety of compround composite insulation plate.
Q: Please answer the questions about the packing and transportation requirements of refractory materials.. Requirements for packing of refractory bricks
Bricks are usually made from pallets.Generally take the automotive, coastal sea city.
Q: What kind of refractory bricks material is best?
In general, aluminous fireclay brick is used. GB / T 3994-2005 insulating fireclay brick. Bricks with good material are as follows: high-grade thermal insulation refractory brick, GB/T 3995-2006 high alumina thermal insulation refractory brick. Model is A13, and the texture is aluminium oxide. A13 50u, high grade heat insulating brick B5; intermediate heat insulating brick B2, etc.
Q: What are the requirements for the performance of refractory materials?
Refractory materials should have very high refractoriness, high temperature heat load and resistance to softening, melting; with high volume stability, resistance to high temperature and heat load, volume shrinkage and only uniform expansion; high strength at room temperature and high temperature strength, high load softening temperature, under the joint action of heat load and heavy load, no loss of strength, creep collapse; Electric furnace analysis should have good resistance to thermal shock, resistance to rapid temperature changes, no crack, not flaking; with excellent slag resistance.
Q: How many fire endurance grades are the AAA fire resisting shutter divided?
The fire shutter is divided into A / B / C classes. The refractory limits are not less than 1.2 /0.9 /0.6 hours. References to "general technical specification for steel fire resistance rolling shutter door GB 14102-93". 4.3 4.3.1 Classification according to fire resistance time. The common steel fire resisting shutter(see Table 3) The categories of the codes of the refractory time hF1 1.5F2 2.04.3.2 composite steel fire shutter composite steel fire shutter(see Table 4). Table 4 and Category Code refractory time hF3 2.5F4 3.04.4 refractory press time, smoke performance classification 4.4.1 ordinary steel fire anti-cigarette curtain (see Table 5) Table 5 and category code leak smoke refractory time h (20Pa pressure) FY1 1.5 ≤0.2m3 / m minFY2 2.0 ≤0.2m3 / m min4.4.2 composite steel fire anti-cigarette curtain (see table 6) table 6 and category code leak smoke refractory time h (20Pa pressure) FY3 2.5 ≤0.2m3 / m minFY4 3.0 ≤0.2m3 / m min excerpt complete fire shutter when the fire district for fire resistance of 3 hours, the opening portion on the firewall setting fire shutter fire resistance of 1.2 hours. **** Fire resistance of 3.0 hours called premium (fire back surface). "Construction Regulation" is mentioned in setting up a firewall and used as the separation of the fire resisting shutter and the fire?compartments. When taking the fire back surface temperature rise as the fire resistance standard of the fire resisting shutter, the fire endurance should not be less than 3.00h; When taking the fire back surface temperature rise as the fire resistance standard of the fire resisting shutter, the two sides of the roll should have protection of ?closed automatic water spray system, and the duration of water spray system should not less than 3.00h. In summary: The fire resisting shutter can be divided into: Grade, A, B and C looking to adopt
Q: What level is the rock wool board fireproofing material ?
The fire rating classification is a provision for all insulation materials, rather than to separately divide rock wool. Determine the value of the material fire rating according to the relevant test items of 8624. As the rock wool is made from basalt fusion, so it is the level A non-combustible material. And those we usually see are the mineral?cotton and glass wool, with its refractory temperature lower than the rock wool's. Rock wool board is now mainly used in wall insulation, which is a level A fire insulation material.
Q: What's the fire resistance rating of the exterior fire?retardant?coating?
First of all, fire retardant coating has no class distinctions. Buildings fire resistance rating is generally classified as follows: I grade fire resistance, II grade fire resistance, III grade fire resistance, IIII grade fire resistance. Buildings with I grade and II grade fire resistance are much common. According to the coating thickness, exterior fire-resistant coating for steel structure can be classified as follows: 1. Exterior thin fire-resistant coating for steel structure, 2. Exterior ultra-thin fire-resistant coating for steel structure, 3. Exterior thick fire-resistant coating for steel structure.
Q: Who knows the fire endurance of rock wool color plate?
I'm glad to answer your question and offer you some of my experiences, for reference only. rock wool board is artificial inorganic fiber taking basalt as raw material and produced by melting with high temperature, which has characteristics of lightweight, non-combustible, heat absorbing, small thermal conductivity. The initial research is a common type of application in the building mainly used for industrial buildings which should be consistent with provisions in "the application types and basic requirements of building insulation materials". Successfully tested in June, 1981 Rock wool board is a new type material with fuctions of thermal insulation, fire retardant, sound absorption. The fire endurance of general rock wool board is 140-180 degrees, within two hours, better not exceed this safe period, in order to avoid security risks.
Q: Are there any differences between insulation and refractory materials ?
I will explain to you in a simple way. Refractory materials can resist more than 1200 degrees, some of which are not insulation materials, such as firebricks, which can directly contact with heat source, has little insulation effect. Ceramic fiber, high silica, etc. are all refractory materials which can insulate. Insulation materials with poor performance usually is lower than 800 degrees, which have large thermal resistance, and low thermal conductivity, high porosity. Thus they reduce the thermal loss. To put it simply, insulation materials store most of the heat and only let a small part of heat lose through the air, thus the heat has been isolated. Glass fiber, rock wool, flexible material for thermal insulation, etc. I hope you can understand it.
