Products	Calcium Aluminate Cement /High Alumina Cement CA-50
Applications	1,As binders calcium aluminates cement are used in concretes and mortars for specialised applications for their properties of resistance to corrosion, abrasion and heat combined with rapid hardening and the ease of controlling grading variations. Calcium aluminate cements are also used in combination with other fine components. Hydraulic binders with new properties are then obtained. In this way, aluminates act as both a complex hydraulic binder and a mineral reagent interacting with the other components in the mix. 2,As reagents, calcium aluminates are found in non-hydraulic systems. This is the case in metallurgical treatments (iron and steel industry, foundry) where specific grades of calcium aluminate are used for their low-temperature melting properties and for trapping molten metal impurities.
Features	1,Very low mixing-water requirement
2,Very high purity
3,High product consistency
4,High cold and sintered strength
5,Very tight specifications of setting times

Q:Detailed description of magnesia dolomite refractory material?: In the cement kiln firing zone, the f-CaO in the dolomite material is easily combined with the C2S in the clinker to form C3S, so the kiln cover can be easily hung, and the kiln crust and the refractory brick are firmly combined and easy to maintain.

Q:Which brand of AAA refractory is good?: Rong Sheng Kerui quality refractory Zhengyuan Shenzhou Saatchi these brands are very good, with high refractoriness, durability and with a good cost performance. Get the majority of customers' recognition.

Q:how to divided the external wall thermal insulation materials fire rating: Level A: Incombustible building material: It is a kind of material that almost does not occur burning. Level B1: Nonflammable building material: Non-flame material has good flame resistance. It is difficult to fire under the condition of open fire in the air or high temperature, and it is not easy to quickly spread, and when the combustion?source is removed, the combustion will stop immediately. Level B2: Combustible?building?materials: Flame material has a good flame resistance. In case of fire in the air or at high temperature, it will immediately burst into flames, and easily lead to the spread of fire, such as wooden column, timber roof truss, timber beam and wooden stairs. Level B3: Combustible?building?materials: It has no any flame resisting effects, and is easy to burn, so the fire risk is high.

Q:How to calculate the thickness of choosing refractory? Such as steel ladle should choose what kind of refractory and using what thicknes?: The relative production is lower and material cost is higher, the lining of the refractory is thicker: 1, determine the weight of the refractory material according to the main structure of the bearing capacity, to prevent damage to equipment, fire-proof material damage after the surplus size and thickness of the thermal conductivity of refractory materials, the smaller the effective volume, production output, the cost of materials) to consider the selection of refractory material thickness. 3 from the point of usage (usage cycle, relative usage cycle is longer, because under the condition of invariable in the device's overall dimensions of the refractory lining thickness to determine several basic principles, according to the volume of the weight computation of refractories and refractory thickness, these items must be fully consider the pros and cons before decided. 2 according to maximum temperature that shell can withstand.

Q:How to divide fire rating of decorating materials ?: The combustion performance of building materials is divided into the following grades by the national standard GB8624-97: level A: incombustible building materials, almost no burning material. Level B1: Flame retardant building materials, such kind of materials are effective in flame retardance. It is difficult to fire in the air in the case of open flame or under high temperature, it is not easy to spread quickly, and when the fire source is removed , the fire stopped immediately. Level B2: combustible building materials. Combustible building materials are effective in flame retardance. It will immediately burst into flames in the air in case of fire or under high temperature, and it is inclined to lead to the spread of fire, such as wooden, wooden frame, beams, wood stairs,etc. Level B3: Flammable building materials: they have no effect in flame retardance, easy to burn, fire risk is very huge.

Q:What are the best refractory materials in 2,400 Celsius degree?: and carbon fiber or nanomaterials.

Q:What are the basic requirements of continuous casting for molten steel? What are the requirements for refractory materials?: Refractories for continuous casting is an important part of the continuous casting machine, in addition to the characteristics of general refractory material, also for the purification of molten steel and improve the steel quality, stable molten steel temperature and composition, control and regulate the flow of the molten steel and other functions, so it is called functional refractories. The above is provided by the China Technology Department

Q:What advantage and disadvantages it has compared to common fire insulation materials: Main advantage of A-level fire proof heat retaining plate is A-level non-conbustibility. Now residential areas strictly require the external walls to be high-level fire proof, to be specific, high fire resistance, non combustible. Standards for evaluation varies according to different types, which includes anti-corrosion, acid and alkali resistance, waterproof, anti termites and so on. Disadvantage is the insulation effect is quite ordinary. It will absorb water, get deformed, need some water prevention measures after constrcuting thermal insulating layer for it. Its thermal conductivity far below the benzene plate, and plastic extruded palte, half the thickness of the polyurethane insulation layer can reach heat perservation effectiveness of the benzene plate and extruded plate of the same thickness.

Q:How to distinguish the fire resistant level of the rubber and plastic thermal insulation material?: It is divided into level A, B1, B2 and B3. According to the current "burning behavior of building materials classification method", Level A insulation material is a non-combustible material, which belongs to YT. However, from the point of view of the current market , level A insulation material are very few, only glass wool, rock wool board, foam glass and vitrified micro bead. However, compared with level A insulation material, the more welcomed by the market is the organic insulation material. This is characterized as thermal insulation material, which is divided into three levels: level B1 is flame retardant, level B2 is flammable and level B3 is flammable. The level B1 nonflammable thermal insulation material is determined according to the fire endurance of the material. And different parts of the material are divided differently! Such as the common EPS / XPS insulation boards through special treatment of adding flame retardant. . Level B2 combustible insulation material is commonly the EPS expanded polystyrene foam insulation board and XPS board, that is, the ordinary plate. This material has low ignition point, and releases large amounts of harmful gases in the combustion process . Level B3 flammable insulation material is commonly the thermal insulation material taking polystyrene foam as the main material. Since this material is highly flammable, it has been out of the external wall thermal insulation materials. As for the civil construction insulation materials, China's current popular building insulation materials in the market are mainly made of three organic foams: EPS (molded polystyrene board), XPS (extruded polystyrene board) and PU (polyurethane).

Q:In entering fire door, which material does well?: Entering door has two kinds: security doors, fire security door. The pure fire door does not have anti-theft function. In the relevant technical standards of fire doors : when in the fire, it can make residents in a few seconds or 1 minutes forget to open the door... The material of fire door, fire door has steel fire door and wooden fire door. There is no doubt that wooden fire door can't be used as entering door. In the steel fire door, two layers of steel plate in the clip is flame retardant material.
