- Q: Can someone professionally introduce the classifications of refractories?
- Whatare the classifications of the refractory index levels? There are three categories of refractory index levels. Anyone familiar with the industry may already know that if you're new to the refractory and don't know much about it, the following information may be helpful to you. Refractory index level can be devided into three general categories of special refractories, advanced refractories and ordinary refractories. The first category, special refractories. Whose refractoriness is higher than 2000 ℃, spinel brick, pure oxide products, high purity directly bonded magnesia-chrome brick, cast products, non-oxide products belong to this grade. The second category, advanced refractories. Whose refractoriness is from 1770 to 2000 Celsius degrees, mullite bricks, high alumina brick, magnesia-alumina brick, ordinary magnesia products, olivine bricks, ordinary magnesia-chrome brick belong to this grade. The third category, ordinary refractories. Whose refractoriness is between 1580 and 1770 Celsius degrees, equivalent to Al2O315% ~ 45% refractory products in the binary system of SiO2-Al2O3. Kaolinite is the main mineral of raw materials.
- Q: What is streaming fireproof material?
- Streaming fireproof material is castable refractory that can flow and degas without virbration, which is suitable for thin-wall or places that cannot be molded by vibration because of complex shapes. Well, appropriate amount of water is necessary for it. Its characteristic goes that it can be cast into various shapes of construction body without virbration and it will not reduce or not significantly reduce the performance of castable at the same time.
- Q: What's the organzational structure of refractory material?
- Although hacing same chemical composition refractory material products also is mineral organizer. There are differences in the type of mineral phase, high refractoriness under load, quantity and crystalline state. The organizing minerals and microstructure are reflected by folding strength, high temperature pit definite density torsional strength, high-temperature torsional strength and product property. But, for example, wear or crack may cause damage. The performance index can reflect the internal structure of refractory: the nature of the thermal performance---linear expansion coeffcient. And the mineral composition of refractory material depends on the chemical composition and process conditions, the heat capacity and temperature conductivity. If the processing conditions are different, the influence of chemical action, and thermal conductivity: represents the nature of the mechanical properties - normal temperature, high temperature compression strength, high temperature creep performance and elastic modulus. Chemical compositions are the basic characteristics of refractory, representing the nature of the density---porosity, corrosion occurred refractory materials in high temperature use As a result, the composition and quantity directly determines the performance of refractory, true density: representing the forming of high temperature performance --- refractoriness, high temperature volume stability, so you can't analyze the effect on the product performance just from chemical composition. The performance of various refractory materials are different. It must be emphasized that macroscopic organization structure of refractory material is also an important factor that affects performance; reflecting complexity of penetration---air permeability, thermal shock resistance and slag resistance. The main component is the foundation of refractory characteristics.
- Q: What is the appropiate thickness if fire resistant time for ultra thin steel structure coating is 2.5 hours?
- Hello steel structure can adopt surrounding concrete or brick, fireproof coating, fireproof board coating and composite structure for its fire resisitance. Fire resisitance board can be divided into thick fire protection plate and thin plate, the thickness of the plate thickness of the fire is between 20 ~ 50mm, mainly includes calcium silicate fireproof board and expansion boring stone fire board, the main varieties are KB board, CF; thin fireproof plate is between 6 ~ 15mm thick, the main varieties include enforced short fiber cement plate, ordinary enforced fiber silicate calcium board and glass cloth reinforced inorganic board.
- Q: What kind of material is refractory bauxite?
- Bauxite, also known as bauxite alumina or bauxite with high alumina, is the main raw material for the production of high alumina (aluminum content ≥48%, belongs to LAS) refractory. It must be calcined bauxite ore.
- Q: What's the heat conductivity coefficient, specific heat capacity and density of the refractory material of magnesite-chrome brick and magnesia-alumina brick respectively?
- It is suggested that you find some samples of well-known manufacturers, such as Ogilvy and Mather Group, and that will be more correct.
- Q: What crusher is used for raw material of broken refractory material? What is the rough crushing process? What are the materials? Thank you!
- What are the requirements of granularity of material?
- Q: can slag tailings be used to be the base materials of refractory materials ?
- the rest of it can be used as refractory additives. the scale currently used clay bricks to make high-temperature liquid. It is easy to produce large amounts of liquid because of the high iron content, instead of its refractoriness. But it can be used as refractory minaralizer.
- 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: Is there a worker in (Jigang refractory plant)?
- Exactly, you are not in the strict sense of the refractory plant contract worker, your contract is not signed and refractory plant, your wage system, and the worker in the factory is not the same, you can not follow the normal off-duty execution system
