- Q:what textures of furnace refractories are good?
- First, it depends on the kiln. If it is the cubic kiln, the top and the wall portion should use alumina hollow ball bricks. The bent seal and kiln car use heavy corundum bricks. If it is the consecutive kiln, the burning zone shall all use the alumina hollow ball bricks, and both the burning zone bent seal and the brick kiln car bent seal use the heavy corundum bricks. Ifit is the pit furnace, furnace walls and roof use the alumina hollow ball bricks, and the bottom of the furnace use heavy corundum bricks.
- Q:The manufacturing technique of refractory material
- Melt blowing method is to melt the ingredients first, In addition, hiphotos, organic impurities, to be mixed, add sulfite pulp waste liquid into magnesia billet , ensure the accuracy of the product dimension. The products are mainly used for light refractory. then dry and fire with sintering to reduce the firing shrinkage of products, making it disperse into fiber or hollow sphere. The porpose of pre sintering raw material is to Sintering method is pre-sintering part of the raw material into clinker. such as adding binding clay into aluminum silicate blank
- Q:What are the refractories for converter?
- Analysis of refractories are as follows: MgO-C brick converter Dongxin refractory furnace cap, steel tapping hole, shaft, shaft, pool, air brick
- Q:Which are fire proofing thermal insulation materials?
- Fire proofing thermal insulation materials include: fire proofing heat insulating brick, fire proofing thermal baffle, fire proofing thermal insulation paper, fire proofing thermal insulation felt, fire proofing blocking, fire proofing fiber bulker, castable refractory, etc. In addition, there are also auxiliary products such as fire proofing cement gum, high temperature binder.
- Q:What are the advantages and disadvantages of new external wall fireproof and thermal inuslation matertials?
- The new external wall fireproof and thermal inuslation matertials have both the advantages and disadvantages. Advantages: 1)Low requirements on the waterproof, weather resistance and other technical indicators. The dry wall and gypsum plastering mortar, etc. can meet the requirements and can be easily obtained; 2) The inner insulation material are separated by the floor, and construct within a height of only a storey , without erecting scaffold ; 3) In the hot summer and cold winter or hot summer and warm winter area, the inner insulation meets the requirements; 4) The glass beads overcome the shortcomings of expanded perlite, like, large amount water absorption, easy powdering, big volumetric shrinkage in the slurry mixing process, easily leading to post-insulation product performance degradation and hollowing, cracking, and also make up for the defects of polystyrene particles organic materials, like, flammable, poor fire performance, producing harmful gas at high temperatures and anti-aging, poor weather resistance, poor workability and large rebound in construction, ect. Disadvantages of external wall insulation : 1) Since the ring beam, slab and column structure would cause thermal bridges, leading a greater heat loss; 2) It is of low intensity, high water absorption, easy to shrink and crack. The insulation system is prone to cracking, leaking or loss and other common quality problems, especially it is easy to crack at the seams, thus being difficult to exsit as long as the building. 3) It is inconvenient for the users to redecorate and hang ornaments; 4) It takes up indoor used space;
- Q:What are the differences and connections between softening temperature of the refractory under a fixed load and thermal resistant creep property of the refractory?
- The result of refractoriness under load is temperature while the result of creep is percentage of deformation. Refractoriness under load and creep can be tested by an instrument. Refractoriness under load reflects the temperature in which the deformation reaches a certain degree under the condition of load. Creep reflects the deformation refractory has under the condition of constant temperature and load. Both refractoriness under load and creep are important criterion for the operating temperature of refractory.
- Q:Are there any differences between insulation and refractory materials ?
- I will explain to you in a simple way. 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. I hope you can understand it.
- Q:Where is refractory used? Thank you!
- Currently, refractory is widely used as inorganic nonmetallic material of production equipment lining in metallurgy, ceramics and other industries. The current definition of refractory does not only depend on whether the refractoriness is above 1,580℃.
- Q:What kind of material is good for cabinet fireproof board
- What kind of material is good for cabinet fireproof board What are the advantages and disadvantages of using it? How much is the price? A about how much does one piece cost?
- Q:how about the performance of aluminum silicate fire proof thermal insulation?
- aluminum silicate fire proof thermal insulation board has a good performance. it is a artificial board that separates the wood and plant fiber by mechanical and chemical methods and mixed the adhesion agent and water-proofing?agent, molding by high temperature and high press. MDF(medium density fibre board) structure is more even than natural wood. it avoids rot, moth-eaten and other problems, while medium density fiber board has small expansion and contraction, which is easy to be processed. Since the surface of medium density fibre board is smooth, the board is easy to paste a variety of finishings, which makes furniture more beautiful. A variety of decorative wood-based panel is to embellish their homes.
