Q:What are the specific steps of stirring the steel ladle castable?
Steps are as follows. 1 Compulsory mixer is used to stir the castable and bags, rope and other debris can not mix in the castable when stirred. 2, Castable should be unpacked on the scene. Stirred volume depends on the capacity of the mixer. Castable should be accurately measured and put into a blender. 3 The process of first dry mixing and then wet mixing is adopted. After the castable is added to the mixer, it is dryly mixed for 2 minutes, add about 5.2 to 5.5 percent of water and continue to add water while stirring. Water that is 80% of the total should be added, and then decide whether to continue to add or not depending on the consistence (noting that the water must be clean water and sewage can not be used). Then it is wetly mixed for 4 minutes and stirred for not less than 6 minutes at one time, until castable is even. In general, the bottom is slightly dry and the wall of the ladle is slightly dilute (the amount of water is only for reference). 4, The amount of water and mixing time should be controlled strictly when stirred to ensure that the needs of the consistency are met. If castable is too thin, it will seriously affect the quality of the material. The stirred volume, stirring time and water that is added should be consistent and they can not suddenly be thick or suddenly be thin. If the consistency does not meet the requirements, the castable should be put back to the mixer and stirred with appropriate water or dry materials. 5, It should be stirred evenly and casting should finish in 20 minutes, in order to avoid sclerosis, affecting structural strength of ladle lining 6, After each completion of construction, varieties of castable should be changed and the mixer should be cleaned 7, Stirring can stop in halfway. If the mixer breaks down and it can be repaired in a short time, some of the materials have to be removed before the machine is opened. If the machine can be repaired on time, castable refractory should all be removed.
Q:Who knows about the B-level fireproof insulation materials?
Organics, extruded sheet, polyphenyl board and phenolic resin. The fireproof performance of sea capacity module (fireproof and thermal insulation material) is B1-level with the heat conductivity coefficient of only 0.028w / m · k. It is a good choice. A-level: Rock wool, glass wool, silicate, aluminum silicate, calcium silicate, phenolic aldehyde, and foam glass. B-level: Rubber and plastic, extrusion molding, polyphenyl, PEF.
Q:What do refractory materials include?
It is so difficult.
Q:which kind of material is chosen for fireproofing window?
Firstly, fireproofing window glass must be tempered, ordinary glass won't play a role of fireproofing, and fireproofing window fan is fixed, can't be open, if you can open it, it won't play a role of fireproofing. And you can ask the property to provide texture report of fireproofing windows, fireproof material stipulated by our national fire protection laws and regulations must have fireproofing inspection reports, there must be. and fire window glass should have a fireproofing sign. The main role of fireproofing window is to isolate the fire, and play a role of fireproofing and escaping, avoid the fire quickly spread in.
Q:How many types do refractory bricks have? Where the quality of refractory material is best? What is the model?
Sinosteel Luoyang (Luoyang Refractory Material Plant in the past): High alumina(mainly blast furnace), Gongyi. There are also a series of high-tech materials (silicon carbide, carborundum, etc.) a major producer of high alumina; silicious: Resistant material for steel, glass furnace, cement kiln); magnesia. Divide from uses and divide from chemical texture; silicious(glass furnace): Xinmi, Hennan Province, Lengshui River, coke oven, etc.). As for the models, Yixing and Changxing in Jiangsu Province: Haicheng, Liaoning Province; silicious, I do not understand your intentions; magnesia (nonferrous, steel refining; magnesia: High alumina brick; Dashiqiao area! Please put it in detail.
Q:How long is the fire-fighting time of A class fire resisting window?
Fire resisting window' duration of fire resistance: A class window, fire insulation ≥1.50h and fire resistance integrity ≥1.50h. Fire resisting window can be divided into three kinds: 一. window frame and sash framework adopt fire resisting window with steel manufacture ; 二. window frame and sash framework adopt fire resisting window with wooden manufacture; 三. window frame adopt steel and sash adopt wooden material or window frame adopt wooden material and sash framework adopt fire resisting window with steel material.
Q:Fire insulation and fireproof insulation board materials What is the difference in performance?
Fireproof Materials prevents burning through insulating while others by chemical reactions. The overall heat conductivity coefficient of Insulation materials are generally lowered by thermal conductivity of the material itself and the structure of it. Inorganic active insulation material uses ordinary cement, insulation stone, calcium powder, Platycodon grandiflorum as the main raw material.
Q:Who knows the texture of fire-proof wooden door material?
Steel door, wooden door or steel wooden door can be inset fireproof laminboard, such as rock wool, perlite. Perlite (fireproof doors filling material, fireproof doors raw material) using for fireproof door core is mainly used for the filling material of fireproof doors and security doors. Fire protection, thermal insulation, good sound insulation effects, and higher performance than aluminum silicate wool and rock wool. The combustion performance of perlite using for fireproof door core reaches class A non-combustion, which is new type of fireproof doors filling material with characteristics of low cost, good fireproof performance and excellent environmental protection performance. The advantages of fireproof door core perlite as fireproof door filling material: 1, Good fireproof performance, so it has a function of fire prevention. Environmental protection: all materials are environmentally friendly products. Pollution-free: the product is composed of glass fiber reinforced materials and inorganic binder. 2, with characteristics of non-flammable, non-explosive, water-resistant, oil-resistant, chemical erosion resistant, non-toxic and good mechanical strength, etc. The product can be used for mechanic processing like sawing, drilling, gouging, etc. High fire resistance, in the simulated combustion tests, it doesn't deform when the flame temperature reaching 800 degrees, has good fire retardant and fire-resistant properties. 3, product material is cheap, suitable for all kinds of fireproof materials. Perlite fireproof board is made by pressing the expanded perlite powder and high temperature fireproof adhesive through mould, suitable for the filling material of fireproof wooden door and fireproof steel door, which is the substitute products of aluminum silicate wool and rock wool. 4, has advantages of light volume-weight, high refractoriness, strong compressive strength, small thermal conductivity, non-flammable, non-toxic, tasteless, non-pollution, etc.
Q:What is the difference between wear-resistant material and refractory material?
Focus is different. Some materials are called wear-resistant and refractory material. For example, refractory castable with high strength and wear-resistance, impressionable plastic material or brick. They all begin with fire-resistance and wear-resistance.
Q:What's the difference between refractory metal raceway and fireproof raceway?
Refractory metal is used to lay and control cables, while trunking is used to lay wires and communication cables; refractory metal is bigger (200*100-600*200), while trunking is smaller; refractory metal has bigger turning radius, while trunking mostly turns a right angle; refractory metal has larger span, while trunking has smaller span; their fixation and installation ways are also different.
