Qaulity Control of High Aluminum Insulating Castable Refractory for High-temperature Industrial KilnsHigh Aluminum Insulating Castable Refractory for High-temperature Industrial Kilns

Raw Material Selection: To ensure the quality of our raw materials, we only purchase our raw materials from our long-term trusted suppliers. With every purchase, the raw material must be passed 2 times inspecition, 1 time at our supplier’s site. a second inspection on the batch after the material arrived to our factory. Each time raw materials enter our facility, they are inspected again prior to being accepted.

Process Quality Control: Starting from the raw material into factory, Every production process of  Insulating Castable Refractory should through strict quality control, In addition to rigorous process control, our quality control team inspects the output of each process to ensure material quality and consistency. We do our best to supply the products with best quality to satisfy our customers.

Q:Why should graphitic refractory materials be used now that graphite can burn?
In theory, any substance can burn as long as certain temperature is reached. Graphite is turned from diamond under anaerobic condition and at high temperature of 2 000 ~ 3 000 ℃. that is to say, ignition point of graphite (lamellar graphite ) under anaerobic condition will be at least above 3 000 ℃. There are many types of graphite, and their ignition points are also different. Ignition point of pyrolytic graphite is much low. Except for a few cutting-edge areas, fire endurance demand for most areas in daily life (eg. brake pad will add a certain amount of graphite) is under 1000 ℃. Therefore, graphite can be used as refractory material. That is, graphite can both burn and can be used as refractory material, which are not contradictory.
Q:What kinds of refractory will be used in kiln of sintering ceramics?
Porcelain has many classes, including acid, alkaline and neutral materials.
Q:What's the commonly used refractory material for ladle?
1. According to the refractoriness, it can be classified as follows: common refractory: 1580℃ ~ 1770℃; high grade refractory: 1770℃ ~ 2000℃; superrefractory: 2000 ℃; 2. According to the shape and demension of the product, it can be classified as follows: standard form : 230mm×113mm ×65mm of no more than four measuring scale, (demension ratio) Max: Min
Q:What are grades of refractory materials?
Refractories have lots of varieties which all have different purposes. It is necessary to classify refractories scientifically in order to scientifically study, choose and manage them. Classification methods of refractories include chemical properties classification, chemical composition of mineral classification, manufacturing technique classification, morphology of the material classification. 1 divided according to the level of refractoriness: ordinary refractory materials: 1580 ℃ ~ 1770 ℃, advanced refractories: 1770 ℃ ~ 2000 ℃ and super refractories: above 2000 ℃ 2, divided in accordance with shapes and sizes : Standard ones: 230mm × 113mm × 65mm, no more than four ruler.
Q:Could you tell me the fire-resisting time of class B fire proof door?
The fire-resisting time of class B fire proof door is 1h and thickness of door can't be lower than 45mm.
Q:whether the aluminum silicate thermal insulation material is fireproof or not?
aluminum silicate is fireproof, and the melting point is between -40 ~ 800 ℃. Aluminum: it takes the flint clay clinker as raw material, produced by resistance or electric arc furnace fusion and injection fiber-forming process. its characteristics: Low thermal conductivity, excellent thermal and chemical stability, without binder and corrosive material.
Q:The difference between refractory and thermal insulation material
Refractory refers to inorganic non-metallic material, whose refractoriness is not less than 1,580℃, but refractory is not necessarily insulated material. Inorganic thermal insulated material also belongs to refractory as long as its refractoriness is higher than 1,580℃.
Q:Fire rating of decoration materials
You can refer to (code for fire protection design of buildings)
Q:Which kind of refractory does insulation board belong to ?
Q:Are refractory materials and fireproofing materials the same?
Refractories are generally used in the industry such as power plants, electric stove and industrial furnace. They include refractory bricks and insulation materials. Fireproof materials are generally used in building and they are fireproofing.
