Q:What's the fire resistance test method of doors and roller shutters?
Fire resistance test method of doors and roller shutters: This standard specifies the fire resistance test method for roller shutter doors under standard fire conditions. The method is used to test the fire resistance of the ventilating duct when bearing the external fire (A duct) and internal fire (B duct). Fire resistance test of vertical ducts may be conducted referring to this standard. 1.Test specimen1.1 The test specimen is obtained by cutting from any part of the qualified metal tube unless otherwise relevant standard or mutual agreement specifies the cutting position of the metal tube. 1.2 Length of the specimen: L≈2.5D+50mm (D: outer diameter of the metal tube). The cut surface of the specimen must be perpendicular to the axis of the metal , and the seamed edge of the cut should be round off. Test method GB243-82 of metal tube necking 2. Test procedures 2.1 In the test, punch or press the metal tube into the tapered conical seat (see Figure) with a hammer or press machine, and make it uniformly diminished to the regulated shrinkage X which is calculated according to the following formula: Test method GB243-822 for metallic pipe necking: The inner wall of the seat cover used in the test should be polished, and has certain hardness and is coated with lubricating oil. Its conicity is 1:10, 1:5 or others in accordance with relevant standard provisions. If there is no provision, then adopt the conicity of 1:10. This standard is not suitable for: a) The pipeline whose fire resistance depends on the fire resistance of the ceiling; b) The pipeline with access door, unless otherwise the access door is included into the pipeline and tested together; c) The pipeline with two or three sides; d) Fume exhaust pipes;
Q:What are the applications of refractory?
Refractory usually refers to the inorganic non-metallic material, whose refractoriness is above 1580℃. And it can be used for necessary parts. You can search more information on the Internet. It can be used in ferrous metal metallurgy, chemical, ceramics and so on. Fire material generally refers to above 1580 ℃ refractoriness of inorganic material, where the material can be used in corrosion, the network is very strong look, we know that colored when the metallurgical, chemical-resistant ceramics, etc. of industrial production high temperature. Different things are needed in different industries.
Q:What are the main characteristics of the sic refractories?
The physical properties of SiC refractories include structural properties, thermal properties, mechanical properties, usability and job performance. The structural properties of refractory include porosity, bulk density, water absorption, air permeability, an the distribution of pore size. The thermal properties of refractory include thermal conductivity, thermal expansion coefficient, specific heat, heat capacity, thermal diffusivity, and thermal emission rate. The mechanical properties of refractories include withstand voltage strength, tensile strength, anti bending strength, torsional strength, shear strength, impact strength, abrasion resistance, creep resistance, adhesive strength, and elasticity modulus. The usability of refractories include refractoriness, load softening temperature, linear?change?on?reheating, thermal shock resistant performance, slag resistance, acid resistance, alkali resistance, hydration resistance, corrosion resistance to CO, conductivity, and inoxidizability.
Q:What is neutral refractory? Can refractory suppliers tell the main components of it?

Q:Who knows that among refractory materials, insulation boards from which refractory material industry is superior in quality?
Using high temperature insulation material during casting process .In the molding, assembly the insulation?board on the ingot head or install heat insulation cap . There are three ways to install the molded steel insulation board and install insulation?board on at the head of the ingot, namely, clamping, nail fixation and mosaic technique.Compared with clay-based liner, the use of insulating board will improve high steel billet rate up to about 5% to 10%.
Q:For refractory, what is critical particle size? Thank you.
0
Q:How many types of special refractories are there?
Metal ceramics, high temperature coatings, high temperature fiber and other reinforced materials
Q:What are the meanings of azs, 34% and ec in fused brick?
The fused brick, also called zircon corundum brick, is shorted as AZS for three chemical components in Al2O3-ZrO2-SiO2 ternary diagram. I don't know the meaning of EC.
Q:What is the upper temperature limit for refractory materials?
The key depends on what refractories you use
Q:I wanna ask what are the acidic refractories?
Usually, acidic refractory refers to a kind of refractory which contains a amount of silicon?dioxide. There are the following: (1) silica?brick with stronge acidity, unshaped silicious refractory, quartz glass and fused silica combined products; (2) semi-silica refractory with moderate acidity and pyrophyllite refractory; (3) clay-based refractory with weak acidity. The main features of the acidic refractories is resistant to the erosion of acidic substances (acidic residue) in high temperature, but is easy to react with alkaline material (basic slag). zirconite fireproofing material and silicon carbide as the special acidic refractories refractories are also in this category.
