- Q: How to solve the shell, the crack problem of refractory material in the process of forming.
- Pressure mode and number of pressure control "spallation". 2, multiple pressure, pressure degree and discharge way: 1, reduce friction, choose appropriate, than big pressure disposable pressure produced by the plastic deformation, allocate reasonable grading, internal and external friction, reduce billet particles and high die wall bright. 4.--- solve the light one firstly. --moisture content being too high easily cause spallation - the compressibility of water is small and have certain elasticity, appropriately to extend the pressuring time is beneficial. The material can produce large plastic deformation under the effect of continuous load. The right amount of lubricant. - body under the condition of less pressure but long effect time molding. Mould structure is reasonable and improve billet natural stacking density. 5.3, measures to improve the unburned brick molding quality. Many times continuously pressure relief is better than one-off sudden unloading, and controlling the appropriate moisture content;- - is beneficial to air overflow.
- Q: Does the production of refractory belong to advanced technology？
- Refractories production is advanced technology supported by the state. The refractory enterprise is high-tech enterprises and it needs to apply for it in science and technology bureau.
- Q: How many hours of the fire endurance time of the rock wool laminboard?
- Limit is usually two hours. Pay attention to it please.
- Q: What things and cement mixed can act as refractory?
- Cement building, portland cement, refractory grade, calcium aluminate. Cement acts as refractory need to use calcium aluminate cement.
- Q: Who knows which chrome refractories produced by the Henan refractory plant can be used for continuous casting?
- The sand is used as the filling material for the bottom of the ladle. Zhengzhou real iron refractory Co., Ltd. is specialized in the production of non-ferrous industries. All kinds of refractory materials used in glass kilns and cement kilns are sold directly by manufacturers. The prices are reasonable.
- Q: What thickness is needed of the ultra-thin fireproof paint with a fireproof time of 2.5 hours?
- There are two kinds: 1, the thickness of the plate is between 20 ~ 50 mm with composite structure 2, sheet thickness is between 6 ~ 15 mm calcium silicate fire prevention board.
- Q: what are the types of piping insulation material fire?rating?
- according to China's national standard GB8624-97, the combustion performance of construction materials can be divided into several grades grade A: Incombustible building material: Almost no burning material. Class B1: nonflammable building material: nonflammable material has a good flame resistance effect. when it meet the open fire in the air or burnd at high temperature, it is difficult to spread quickly, and when the fire source is removed, the combustion stop immediately. Class B2: flammable building material: flammable material has a good flame resistance effect. when it meets open fire in the air or at high temperature, it will immediately burst into flames and easily cause fire spread, such as wooden column, timber roof truss, timber beam, and wooden stairs,ect.. Class B3: inflammable building material: No flame resisting effects, highly flammable, high fire risk. 2, external wall thermal insulation materials, in accordance with fire rating, can be divided into1) grade A combustion performance thermal insulation material: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite ect.. 2) class B1 combustion performance insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde, gelatine powder polyphenyl granule, etc. 3) combustion performance of class B2 insulation material: molding polystyrene board(EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
- Q: what textures of furnace refractories are good?
- Common ceramics use ordinary clay and high alumina bricks, as well as thermal insulation bricks, calcium silicate boards and fiber cotton. The vessels fired with potter's earth are called pottery, and the vessels fired with porcelain clay are called porcelain. Ceramic is generic term of pottery, stoneware and porcelain. The objects taking the two different types of clay as the raw materials, like, potter's earth and porcelain clay, and made through the technological process of ingredients, forming, drying and roasting, ect. can be called ceramics.
- Q: What is the biggest difference between refractory bricks and clay refractory bricks? Where can I find information on the refractory bricks?
- You can look up knowledge manual of refractory material to find phosphatic material, etc. Xinjiang refractory bricks, castable refractory, refractory material, silicious, corundum and alumina-magnesia: High alumina and clay refractory bricks can be divided into
