Q: What is the requirement of refractory concrete for raw materials? What is the main principle of commercial mixing station?: There are many kinds of raw materials used, three, two aluminum oxide is one of the most commonly used raw materials, as well as alumina, hollow ball, Magnesium Oxide, zircon, etc., or the specific design temperature and the use of parts.

Q: Is the ball mill used in production of refractories?: It depends on what refractory you produce.

Q: What's the poured refractory material?: According to the volume density, it can be classified as follows: Heavy (>2.0g /cm3), medium heavy (1.0-2.0g/cm3), light (0.4-1.0g/cm3); classified by binding agent: hydraulic bond, chemical bond, coagulation binder, hydraulic and coagulation binder; classified by material: material of clayey, high alumina, silicious, magnesian, alumina-magnesia, magnesian-chrome, magnesia-zirconia, silicon carbide-based, etc.

Q: Why do magnesium oxide refractory bricks can be made into refractories?: Nature: It is loose white powder and tasteless. When exposed to the air, it is easy to absorb moisture and carbon dioxide. It is dissolved in acid and ammonium salt and insoluble in water and ethanol, with the melting point of 2800 and the boiling point of 3600. The magnesium oxide has high fire-resistance insulation properties, with high melting point . It can be said to be non-combustible materials.

Q: What are the characteristics of the carbon composite refractories?: The features of carbon composite refractories: 1. It is with an aggressive high thermal shock resistance 2. Good resistance to molten steel and slag

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 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: Who knows about the types of Dalian thermal insulating and refractory materials?: There are mainly following types: rock wool series, rubber and plastic series, glass wool series, mesh series, ventilation series, mortar series, extruded sheet series, geothermal series, insulation supporting pin series, glass silk cloth series. I hope my answer can help you.
