Q:Which kind of furnace hearth refractory is better?
hearth selected material] hearth material must be durable, high temperature resistant, general selecting masnory made of refractory cement, silicon carbide refractory products, mullite or multicrystal mullite (which is the general term of minerals composed of a series of aluminum silicate, mullite is only stable binary compound in the Al2O3-SiO2 system) etc.. [hearth] is a three-dimensional space surrounded by furnace walls for combustion of the fuel. The funtion of hearth is to ensure the fuel to burn as far as possible, and to cool the gas temperature of the hearth exit to the allowed temperature of convection heating surface safe operation . Therefore, the hearth should have sufficient space and adequate heating surface. In addition, there should be reasonable shape and size in order to fit the burner and the organize aerodynamic field inside the furnace to prevent the flame from adherence, dashing walls and have high fullness and eve wall thermal load.
Q:What kind of fireproof material is used for steel structure?
Steel is a building material that does not burn, it is shock resistant and anti-bending. In practice, Steel can increase load capacity of the building, but also add asthetic beauty to the architecture design; Unlike concrete, it can bend and stretch. Therefore, the steel construction industry has been favored, such as one-story or multi-story buildings, skyscrapers, factories, warehouses, waiting rooms and waiting hall, which is the common use of steel. However, the steel as building materials has unavoidable defects in fire prevention, its mechanical properties such as yield point, tensile strength and modulus of elasticity, decrease abruptly due to temperature rise.
Q:Is it normal for caable fire resistant material to catch on fire?
Abnormal; aging is certainly one of the cause of the fire. That is caused only because of poor insulation and aging caused by short circuit, but a more important reason is configuration of air switch does not meet the requirements. If the capacity of air switch equals that of the cable, trip will happen at the moment when current is overloaded, not causing a short circuit or over current fire.
Q:What are the requirements of refractory temperature of refractory brick?
Refractory temperature of refractory brick is 1650 degree.
Q:Is there requirement for radiation indicator in refractory?
All refractories have no radiated harm to environment, so there is no requirement. From the elemental analysis, magnesite. I do not know it is helpful to you. But for refractory rwa material, any chemical element is radiated, including silicon dioxide; If they are radioactive. From the use analysis, such as bauxite, do not have use value.
Q:What material is refractory material?
Basic refractory materials, basic refractory, CaO, basic, MgO style alkaline earth oxide. The refractory materials mainly refers to magnesia refractories, dolomitic and lime refractory refractory. Main categories: (1) strongly basic magnesite brick, magnesia carbon brick, limestone and dolomite brick refractory materials;(2) alkalescent magnesia chrome refractories, forsterite refractory, magnalium and magnesia-chrome spinel refractory, basic refractory materials, high-temperature caustic slag, alkaline solvent resistance, strongly acidic slag flux or acidic refractory. The reaction is mainly used in steel furnace such as colour metal smelting furnace and cement kiln.
Q:Can anyone tell me what material the first rate fire resistant door is?
Material of Class A fire doors can be divided into steel and wood, so fire doors can be divided into fireproof steel door and fireproof wooden door. In fact, fire doors of all classes are divided into steel, wood, steel and wood, and other materials (see GB ). Mainly depending on what kind of material the customers want. The fire door is called class A fire door not because of the material but because of the fire-resistant time. The fire resistant time of class A fire door is not less than 1.2 hours and fire doors as long as meeting this condition can be called class A fire doors . The filling material in class A fire doors is generally perlite, whose difference is in thickness. A few of them will use fireproofing materials like foam core board, vermiculite fireproof board, MC composite material and so on. The thickness of class A fire door is usually 50mm. I hope my answer can help you.
Q:Physical and chemical indicators of various refractory.
it depends on what it is for. There are thousands of kinds of refracroties. You should just ask what you need.
Q:What the fireproofing materialare of the refractory kettle and where they can be sold?
Many places sell these. Nearly 10 years, can't brun when it is dry, adsorption. You can also baidu these materials. Heat transfer evenly, feldspar, clay and other raw materials with a ceramic products. Traditional casserole can not resist heat difference and also can withstand for 100 high temperature without crack. Aiming at the problem of traditional casserole, easy to crack and air permeability, people joined the spodumene on raw material, produce a high-temperature resistance casserole. It is produced after the high temperature burning makes an earthenware pot to keep the original advantages. Hebei has many places to sell these materials and is also relatively cheaper. The traditional casserole has features of not easy to transfer heat's quartz and slow cooling. Due to production technology and raw materials, it greatly improves the casserole' practicability after research and improvement.
Q:What does the function of SiC for refractories?
The main feature is with high temperature, the wear gold resistance of refractory is recognized by our customers. Hope my answer will help you.
