Description of High Alumina Refractory Cement
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. 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:How is the fire endurance of the fireproof paint?
- second level firerpoof of cooling rack. with a fire endurance from 1 to 1.5 hours. According to the code for fire protection design of buildings. 1. fireproof grading of first level is 1.5 hours 2, fireproof grading of second level is 1.0hour.
- Q:Who knows how many kinds of fireproof insulation materials are there in the market?
- Portland cement, insulation stone, calcium powder and platycodon grandiflorum are the main raw materials of inorganic active insulation materials. Advanced manufacturing techniques and chemical Technologies have been used to conduct many tests, thus the close-celled inorganic active insulation materials are successfully developed. Products have advantages of fire-resistance, small deformation coefficient, aging-resistance, stable performance, environmentally-friendly, and good compatibility with rendering coating and subtractive wall, security, stability, and also have a life as long as the building itself. Good fireproofness: The materials of fireproof insulation board are inorganic (cement) which has A1-level fire-resistance, are non-combustible materials, and good at resisting fire. I hope my answer can help you.
- Q:What are the main characteristics of the sic refractories?
- The physical properties of SiC refractories include structural properties, thermal properties, mechanical properties, usability and job performance. The structural properties of refractory include porosity, bulk density, water absorption, air permeability, an the distribution of pore size. The thermal properties of refractory include thermal conductivity, thermal expansion coefficient, specific heat, heat capacity, thermal diffusivity, and thermal emission rate. The mechanical properties of refractories include withstand voltage strength, tensile strength, anti bending strength, torsional strength, shear strength, impact strength, abrasion resistance, creep resistance, adhesive strength, and elasticity modulus. The usability of refractories include refractoriness, load softening temperature, linear?change?on?reheating, thermal shock resistant performance, slag resistance, acid resistance, alkali resistance, hydration resistance, corrosion resistance to CO, conductivity, and inoxidizability.
- Q:What are the applications of refractory busway?
- Is an ieal power supply equipment for modern large and medium-sized enterprises, high buildings, the introduced projects, experimental base and other places.
- Q:How many kinds of A-level fireproof and thermal insulation materials are there?
- Shenyang polystyrene board, extruded sheet, polystyrene particles, and polystyrene plastic plates...
- 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:Is fireclay corrosive?
- No. All of the refractory materials have stable chemical properties and their usability can be guaranteed under high temperatures.
- Q:I wanna ask about the building insulation materials fire rating?
- the classfication of building insulation materials fire rating: 1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3, combustion performance is level B2 insulation material: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
- Q:How is the grading of the level A new material fire insulation material?
- The standard to distinguish level A and level B is the different fireproofing coefficient. The level A is non-combustible. The level B is divided into B1, B2 and B3. B1 is flame retardant, B2 combustible and B3 flammable. The level A is commonly phenolic aldehyde, rock wool, thermal?mortar, foam ceramics, foam glass and foam concrete on the current market. Among the advantages of level A materials, the biggest one is foam concrete currently, also known as foam cement.
- Q:Does the refractory material used in steelmaking all refer to refractory brick?
- The refractory material used in steel making doesn't all refer to refractory brick, but also includes refractory castable. The foaming?agent, ladle filler sand and deoxidizer are not refractory materials but ferrous metallurgy auxiliary materials.
