Low Cement Refractory Castable
Refractory Castable Manufacturer
Al2O3: 45-90%
Density: 2.3-3.2g/m3
Low Iron
This is the low cement refractory castable in the above picture,it was packed in 25kg bags,then 40bags in a ton bag.
TaShan is one of the biggest manufactures for refractory castable in the northern China.Specialized in this area for about 20years.We have advanced production equipment and professional research personnel.Furthermore,we also have complete QCS (Qulity Control System),you can see that in the below photos.TsShan has the production capacity 800tons per month, primarily export to INDIA,USA, AUSTRALIA, JAPAN, KOREAetc.
We are the main supplier of most trading company in our city.
Low Cement Refractory Castable adopts submircon powder technology. Micro powder is used as anchoring agent, aluminate cement as coagulation accelerator, some antidetonant and water reducer will also be added in during the production of Low Cement Refractory Castable. Compared with common Refractory Castable, Low Cement Refractory Castable owns the below characteristics:
1. The dosage of cement is low, the content of calcium only accounts for 1/4-1/3 of common Refractory Castable
2. Wter consumption rate during the construction is almost 1/2 or 1/3 of the common Refractory Castable, so the Low Cement Refractory Castable has high density and low porosity.
3. High normal temperature cure property, intensity will be increased after medium temperature and high temperature. Three or five times more than common Refractory Castable.
4. Good volume stability under high temperature.

- Q:What is refractory brick?
- Capability1. Refractory brick is also known as firebrick. It is faint?yellow or brownish. Refractory brick with 770 ℃ at high temperatures is called for short firebrick. It is mainly used for building and smelting furnace. It is a refractory material made by fring refractory clay or other refractory material.
- Q:What materials is silicious thermal insulation board made of?
- Refractories that contain more than 93% of the monox are acidic refractory materials which include ordinary silica brick, high-density and high-purity silica brick, silica brick that contains chromium, fused quartz products, unburned brick and siliceous ramming materials. It has good softening temperature under a fixed load and can resist corrosion of acid slag, but will have chemical reaction with alkaline slag. Silicious refractory of industrial value mainly is crystalline quartz, such as α and β quartz, tridymite and cristobalite.
- Q:What is the limit of fireproof rolling shutter?
- According to the national standard 14102-2005 GB standard, the provisions of 14102-2005 GB specify that: According to provision 14102-2005 GB: If fire resistance limit of fire resisting shutter is no less than 3 hours, it is AAA fireproof rolling shutter. Therefore, the fire resistance limit of AAA grade fireproof rolling shutter should be 3 hours.
- Q:Is refractory material harmful to human body?
- Chromium oxide is poisonous in alkaline environment, and the gas produced by heating of asphalt, asphalt and refractory material is poisonous............ Go to the real estate company experts, I can think of these
- Q:What are grade classifications of the external walls fireproofing material?
- There are many kind of external walls fireproofing material, according to the document No. 65, the grade of external wall fireproofing material can be divided into: Level A is inorganic insulation non-combustible materials, such as cement foam insulation board, vitrified?micro bead?thermal insulation?mortar, rock wool board, glass wool panels. Level B1 is nonflammable material, mostly are organic material which has added a relatively large amount of flame retardant, such as polystyrene board, extruded sheet, phenolic foam board and polyurethane board. Level B2 is flame-retardant materials, and also known as fire-retardant materials, mostly are organic insulation materials with appropriate amount of flame retardant.
- Q:As for fireproofing material rock wool and glass wool, which one is better?
- Rock wool board and glass?wool?board are a kind of new construction thermal insulation material, it's widely applied in construction and has replaced traditional thermal insulation material to some degree. With the gradually deepening study of rock wool board, glass wool board, we can find that these insulation materials have advantages in many aspects but there are also many deficiencies, particularly there exists a lot of controversy about the impact on the human body. The production process of rock wool board and glass?wool?board usually includes: after melting in high temperature of rock or glass, inorganic fiber is produced by high-speed centrifugation equipment, and at the same time add binder,dust?laying?oil,silicone oil at certain proportion, then produce sheet material according to different requirements. It has good thermal insulation properties, mechanical?property, sound absorption characteristics, belong to incombustible?material and is cheap. In general, insulation, security and economy should not be contradictory, three aspects should be taken into account, balanced chosen and developed. Rock wool board and glass wool board and other such materials should be properly selected and applied to the appropriate structure, so that the choice of material will play their strengths and avoid their weaknesses.
- Q:How long is the duration of fire resistance that fireproof door of level B can endure?
- Fireproof doors can be divided into three levels, namely level A,B,C. Fireproof doors of level A can endure fire for 1.50～2.00h while level B for 0.50～1.50h. However, according to national condition, the lowest fire doors fire resistance limit has been specified, namely, level A,1.50h;level B,1.00h; level C, 0.50h.
- Q:Which industry does refractory belong to? Does it belong to construction industry?
- I am engaged in construction. Refractory material does not necessarily belong to construction industry. Fire resistance is only a part of material?performance. Indeed, there are many places requiring refractory accorded with fire resistant level.
