Q:who knows the uses of refratories?
Physical properties of refractories include structural properties, thermal properties, mechanical properties, usability and operation. structural properties of refractories include porosity, bulk density, water absorption, air permeability, pore size distribution. Refractory thermal properties include thermal conductivity, thermal expansion coefficiency, specific heat, heat capacity, thermal diffusivity, thermal emissivity. Mechanical properties of refractories include compression strength, tensile strength, anti bending strength, torsional strength, shear strength, impact strength, abrasion resistance, creep property, adhesive strength, modulus of elasticity. Refractories are used in various fields of steel, nonferrous metals, glass, cement, ceramics, petrochemical, machinery, boilers, light industry, power, military and other fields of national economy. They are essential materials that ensures the production run and technological development of the above industries, and play an important role in promoting the developemnt of high temperature industrial production. the usability of refractories include refractoriness, softening temperature under a fixed load, linear change on reheating,thermal shock resistant performance,slag resistance, acid resistance, alkali resistance, hydration resistance, carbon monoxide resistance, conductivity, oxidation resistance.
Q:Which industry does the metallurgy and thermal insulating and refractory material belong to?
Materials Industry
Q:How long usually will the A-level fireproof materials prevent the flame?
Having a fire resistance test on any building components -----according to the standard time-temperature curve. This period starts from the time when affected by fire and ends up with losing the ability to support or to insulate fire or the integrity of the components. It can be expressed in hours. A-level fireproof materials can last for 2 hours.
Q:Do you know where I can buy refractories?
Refractories are sold in following companies : Address of Huadu Refractories Co., Ltd. : NO.11 Huanjin Road, Fuyang, Hangzhou Address of Zhenxing Special Fire-Proof Material Co., Ltd. : No. 54 Pingjing Road, Yuhang District, Hangzhou Address of Zhongnai Refractories Co., Ltd.: No. 345 Fuyang, Hangzhou, Zhejiang Province
Q:How is the division of the fire resistant level of the rock wool board?
It's like this: China's national standard GB8624-97 divides the combustion performance of building materials into the following grades. Level A: non-flammable building materials. Level B1: flame-retardant building materials. Level B2: combustible building materials. Level B3 flammable building materials. section II Combustion performance and fire endurance of building components. First, The combustion performance of buildings of building components. The building is composed of components, such as foundation, walls, lubrication columns, beams, plates, roofs and stairs, ect. Building components are constituted by the building materials, whose combustion performance depends on the combustion properties of the used construction materials. Section One Combustion performance of building components. The building components are divided into three categories according to their combustion properties. First, non-combustible component: the component made by incombustible materials. The incombustible material refers to that when meeting the Oxygen in the air, it will not burn.
Q:What materials are needed to make the amorphous refractory bricks?
Amorphous refractory brick is composed of a certain proportion of aggregate and powder, a binder and an additive, and can be directly used without high temperature firing.
Q:What is the upper temperature limit for refractory materials?
The key depends on what refractories you use
Q:What do refractory materials include?
What refractories are included? Refractories include AZS brick, corundum brick, direct-bonded magnesia-chrome, carborundum brick, silicon nitride bonded silicon carbide brick, non-oxide refractory materials such as nitride, silicides, sulfides, borides and carbides, oxidation calcium, chromium oxide, aluminum oxide, magnesium oxide and beryllium oxide.
Q:Who knows the fire resistant level of the rock wool color plate?
Hello; Same with other unprotected steel, the fire endurance of the color steel plate is generally 15 minutes. It is not a fireproofing material, let alone fire resistant level. If the color steel plate has sprayed fire retardant coating and the thermal insulation filling material in the core is rock wool fiber, it can achieve A level fireproofing requirements. The color steel plate refers to the painted steel plate, which is a steel plate with organic coating. The color steel board is divided into the single plate, color steel composite board, floor support board, ect. It is widely used in large public buildings, public plants, portable dwelling, and integrated housing walls and roofings. I hope that will help you.
Q:Are there any differences between insulation and refractory materials ?
Refractory materials can resist more than 1200 degrees, some of which are not insulation materials, such as firebricks, which can directly contact with heat source, has little insulation effect. Ceramic fiber, high silica, etc. are all refractory materials which can insulate. Insulation materials with poor performance usually is lower than 800 degrees, which have large thermal resistance, and low thermal conductivity, high porosity. Thus they reduce the thermal loss. To put it simply, insulation materials store most of the heat and only let a small part of heat lose through the air, thus the heat has been isolated. Glass fiber, rock wool, flexible material for thermal insulation, etc.
