Q: what kind of refractories is used to make the industrial silicon furnace mouth long life?: Fused zirconia corundum brick, the smelter of the glassworks is used this kind of lining, and you can contact by private letter.

Q: What are the materials of white firebricks?: They are made of baked refractory materials with pale yellow and a little brown on the surface and very cheap. They are mainly used to pile up smelting furnace and can withstand high temperature from 580 degrees Celsius to 770 degrees Celsius. While the firebricks, also called refractory bricks by others, have a certain size and shape. They can be classified according to manufacturing process, namely, the unburned bricks, burnt bricks and electrically fused bricks. Also they can be divided into common bricks, standard bricks and specific bricks according to different size and shape.

Q: How can refractory material of the electric furnace be used for longer.: I do not know if you are referring to super high power arc furnace for steelmaking, if you are, I have a easy solution for I have been doing this work.

Q: The mechanism and function of antioxidants in carbon containing composite refractories are briefly described.: 3, the selection principle of antioxidant and its thermodynamic and kinetic mechanism31 selection principles of antioxidants:(1) according to the thermodynamic data and the conditions of use, the possible condensed phase and the vapor pressure of each gas phase are determined;(2) compare the size of each coacervation and oxygen affinity, and the possibility of reaction with CO.(3) the influence of various reactions on the microstructure of brick was analyzed.The thermodynamic and kinetic mechanism of 3.2 antioxidantsFrom a thermodynamic point of view, at the operating temperature, the additives or additives that react with carbon react with oxygen more closely than carbon and oxygen, giving priority to carbon oxidation, thus protecting carbon;From the analysis of dynamics point of view: the compound additive with oxygen and carbon monoxide reaction changed the microstructure of carbon composite refractory materials, such as increasing the density, blocked pores, hinder the diffusion of oxygen and reaction products.

Q: Why the refractories should be waterproof and wetproof: It is necessary to like magnesium carbon, waterproof and wetproof is more important. There is a variety of refractory materials, in general, basic is defective, and wherein the binder and additives water will lose their effect, the relationship is not very high aluminum large amount of water determines how much of the performance after the hydration will affect the strength and high temperature performance ;; hydration & quot, just need a little package like magnesium and calcium-based product itself readily react with water to calcium oxide, magnesium, chromium is not all the material goods have waterproof ordinary bulk materials need to add water before use

Q: How to distinguish the fire?rating of rubber and plastic thermal insulation material?: It is divided into level A, B1, B2 and B3. According to the current "burning behavior of building materials classification method", Level A insulation material is a non-combustible material, which belongs to YT. However, from the point of view of the current market , level A insulation material are very few, only glass wool, rock wool board, foam glass and vitrified micro bead. However, compared with level A insulation material, the more welcomed by the market is the organic insulation material. This is characterized as thermal insulation material, which is divided into three levels: level B1 is flame retardant, level B2 is flammable and level B3 is flammable. The level B1 nonflammable thermal insulation material is determined according to the fire endurance of the material. And different parts of the material are divided differently! Such as the common EPS / XPS insulation boards through special treatment of adding flame retardant. . Level B2 combustible insulation material is commonly the EPS expanded polystyrene foam insulation board and XPS board, that is, the ordinary plate. This material has low ignition point, and releases large amounts of harmful gases in the combustion process . Level B3 flammable insulation material is commonly the thermal insulation material taking polystyrene foam as the main material. Since this material is highly flammable, it has been out of the external wall thermal insulation materials. As for the civil construction insulation materials, China's current popular building insulation materials in the market are mainly made of three organic foams: EPS (molded polystyrene board), XPS (extruded polystyrene board) and PU (polyurethane).

Q: How to deiron refractory?: Our company uses magnetic separation method.

Q: What thickness is needed of the ultra-thin fireproof paint with a fireproof time of 2.5 hours?: The thickness of steel structure fire retardant coating hasn't been regulated in the steel structure application specification (CECS24:90). The above thickness refers to a certain thickness that must (at least) achieve a certain time of the fire resistance. The thickness of fire-retardant coating in engineering is generally determined according to factory inspection report. We use thin steel structure fire retardant coating: 2.5 hours' fire resistance with the thickness of 4.9 mm; 2.0 hours' fire resistance with the thickness of 3.5 mm; 1.5 hours' fire resistance with the thickness of 1.75 mm; 1.0 hours' fire resistance with thickness of 1.17 mm. I hope I can help you.

Q: What is the difference between the fire?rating and the fire resistant level of the fire-fighting equipment?: Fire rating and fire-fighting rating are the misnomer to the building fire resistant level. The building fire risk is measured by fire resistant level. The article 3.2.1 and 5.1.7 of "Architectural design code for fire protection" have made provision respectively on the fire resistant level of plant (the storeroom) and civil construction. Article 3.0.2 of "Code for fire protection design of tall buildings" has made provisions on the fire resistant level of tall buildings. As for the warehouse building "category malonate", it refers to one of the fire risk of goods storage, which is divided into A, B, C, D, E, and each category is refined depending on the nature of different substances. "Malonate class" specified in article 3.1.3 of "building design for fire protection" refers to the flammable solid.

Q: Who knows the fire endurance of rock wool color plate?: I'm glad to answer your question and offer you some of my experiences, for reference only. In fire?safety?rules, it can be divided into non-combustible component, hard-combustible component, combustible component according to the combustible degree of building materials. Rock wool board is building board recombinated artificially by fibers processed by coated steels and inorganic minerals like basalt mineral, because steel plate and rock wool which is the main components are non-combustible material, so rock wool board should be considered as non-combustible component. The fire endurance of rock wool board has its own judging criteria. Lose sustaining power, integrity and fire insulation function. Its fire endurance is within 2 hours.
