- solve the resources and the cost as much as possible. Accurate understanding and knowing the material temperature changes of various partsin order to choose the appropriate refractories. 4： 3, work performance, for example, take measures to ensure the overall life, and it is a very good buying principles: melting in high temperature metal erosion. These are the four major problems to consider when using refractory. You can choose low prices and low transportation costs of materials to meet the basic principles under the conditions described above. 2.carefully observe the material to prevent the desturction and reducing the costs. according to the structure of furnace, reasonable coordination of all parts of the material, fully take the advantages of material characteristics and strive to develop the recycle, to avoid the destruction of the materials.1. the working characteristics and the sport condition and analyze the reason of destroying the material, which can not only gurantee the product quality and reduce the expenses, get familiar with the chemical component and physics of the material.
- Q:What refractories are accessible with ease in daily life?
- Refractory mortar. Thermal insulation refractory materials include diatomite products, refractory castables, monolithic?refractories, carborundum bricks, gun-mix refractories, semi-silica bricks, borides, beryllia, silicide, calcium oxide, high alumina refractory brick, refractory coatings, corundum bricks, fireclay?bricks, silicon nitride bonded silicon carbide bricks, chromium hemitrioxide and other refractories. What refractories can be found mostly in the market? Common refractories. Common refractories include silica bricks. The mostly used unshaped refractories include fettling, ramming refractories, castable refractories, plastic refractories, refractory clay, gun-mix refractory, sling refractories, refractory coatings, lightweight refractory castables, stemming etc. The mostly used insulating refractories include diatomite products, asbestos products, insulation panels, etc. The mostly used special refractories include AZS bricks.
- Q:What are the application of old refractory bricks?
- It can be used for refractory bricks again, as long as the quality is good. It is much more cost-effective than Bayerite.
- Q:Who knows what kind of material the fire-proof plate use, and is it good?
- It is the decorative board made by adopting silicious material or calcareous material as the main raw material, and blending them with certain proportion of fibrous material, lightweight?aggregate, adhesive and chemical?additive before steam pressing. It is a kind of new material and more and more frequently used currently not only for it is fireproof. Construction of the fire-proof plate has higher requirements on the adhesive, and the price of the fire-proof plate with better quality is more expensive than that of the decoration panel. The thickness of the fire-proof plate is generally 0.8mm, 1mm, and 1.2mm. So it is the best material for making cupboards.
- Q:What are the requirements when producing fireproof materials by kaolin?
- Kaolin refractories in fact play a role in two aspects, one is to improve the refractoriness, the second is to improve plasticity of the the refractory . Aluminum content the higher the better, of course, but kaolin is not the only material to improve the content of aluminum, using materials that contain higher content of aluminum such as the bauxite chamotte. So the content of kaolin aluminum does not have to be too high. over 38% is fine. viscosity is important and strong viscidityis better without having to add bentonite. Refractoriness above 1400 degrees is enough.
- Q:Who can introduce the external wall thermal insulation materials fire rating regulations?
- According to public fire-fighting [2007] No. 182, the contents of the notification on the implementation of a number of issues of national standards GB8624-2006 "building materials and products combustion performance classification", since there is large differences between the new version of the standard GB8624-2006 and the old version of GB8624-1997 in the principle, hierarchical structure and test methods. According to the cintent of notification, in order to ensure a smooth transition between the old and new standards, the current national standard "Fireproof? Specification of Building Interior Decoration?Design" GB50222, "fire?safety?rules of tall civil buildings design" GB50045, "Fireproof? Specification of Building Design" GB50016 have not completed the relevant amendments, the new classification method of GB8624-1997 and GB8624-2006 can be used for temporary reference in terms of combustion performance of materials . From GB8624-2006 standard implementation, the classification of combustion performance is too granular, which do not match to the actual construction of the current project in our country. Therefore, the relevant departments carry on the 3rd amendment for the GB8624-2006 standards, namely GB8624-2012, and it will be released on December 31, 2012 and implemented on October 1, 2013. The combustion grading requirements in the standard: Level A is non-combustible materials (products); level B1 is nonflammable material (products); level B2 is combustible materials (products); level B3 is flammable materials (products).
- 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:What is the classification standard of fireproofing material levels?
- Standard: Class A: Incombustible building material, almost without burning. class A1: Non-combustible, no open flame,class A2: Non-combustible,it needs to measure smoke and be qualified. Class B1: Nonflammable building material: Nonflammable materials have good flame resistance function. when it contacts open fire or is under high temperature, it's difficult to burn and be spreading rapidly, and will stop burn after removing the combustion?source. Class B2: Combustible?building?materials: Combustible materials have good flame resistance function. when it contacts open fire or is put in the air at high temperature, it will immediately burst into flames, and easily result in the spreading of fire, such as wooden column, timber roof truss, timber beam, wooden stairs, etc. Class B3: Inflammability building materials, without any flame resisting effects, easy to burn, and has large danger of fire disaster.
