Q:How much refractory material is needed when 1 million ton coke oven is produced?
Q:What is the most reasonable drying heating curve of magnesia refractories? Products of less than 0.5T
You'd better oxidize magnesia preformed unit at room temperature for a longer period of time, then bake it, during which, it's enough to control the maximum temperature within 300 degrees. During the middle process, usually heating up for 4 hours and keep warm for 3 hours. The entire heating up process takes about 20 hours. If it is the site operation magnesia-based castable, it should be heated slowly in the early stage, and pay attention to keeping warm at 80 degrees Celsius. Every manufacturers has their own heating curves, so do not blindly adopt existing curves, try to make your own heating curve.
Q:how does the fire endurance of first rate fire resistant window?
Not less than 1.5 hours
Q:Can someone professionally introduce the classifications of refractories?
Whatare the classifications of the refractory index levels? There are three categories of refractory index levels. Anyone familiar with the industry may already know that if you're new to the refractory and don't know much about it, the following information may be helpful to you. Refractory index level can be devided into three general categories of special refractories, advanced refractories and ordinary refractories. The first category, special refractories. Whose refractoriness is higher than 2000 ℃, spinel brick, pure oxide products, high purity directly bonded magnesia-chrome brick, cast products, non-oxide products belong to this grade. The second category, advanced refractories. Whose refractoriness is from 1770 to 2000 Celsius degrees, mullite bricks, high alumina brick, magnesia-alumina brick, ordinary magnesia products, olivine bricks, ordinary magnesia-chrome brick belong to this grade. The third category, ordinary refractories. Whose refractoriness is between 1580 and 1770 Celsius degrees, equivalent to Al2O315% ~ 45% refractory products in the binary system of SiO2-Al2O3. Kaolinite is the main mineral of raw materials.
Q:What is refractory?
Refractory materials are widely used in metallurgy, machinery manufacturing, chemical industry, petroleum, power and other industrial fields. It is an inorganic nonmetallic material mostly used in metallurgical industry with the minimum refractoriness of 1580 ℃, able to resist high temperature without softening (annealing). It accounts for 50% to 60% in total output. Refractoriness refers to refractory's ability to resist fire.
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:What are the disadvantages of the refractory industry?
The rapid development of continuous casting technology allows Hua Heng refractories to be improved in variety and quality. The development of refractory for continuous casting has a significant impact on the production of continuous casting and quality of continuous casting billet. Constructing and putting Baosteel into action has greatly pushed the improvement of the refractory technology. Continuous casting refractory is an important part of the continuous casting machine. In addition to the general characteristics of refractories, it is also required functions that can purify molten steel, improve the quality of steel, stabilize temperature and composition of the molten steel, control and regulate the molten steel flow. Therefore, it is known as functional refractories. Continuous casting Refractories include: (1) ladle refractory - ladle lining, permanent lining and ventilation components; (2) tundish refractories - permanent lining, coating, insulating plates, clad etc; (3 ) functional refractories - long nozzle for non-oxidizing casting, submerged nozzle, monolithic stopper, sliding gate; (4) ceramic purifier for purifying molten , slag dam, alkaline paint and horizontal separating ring and gate board for continuous casting.
Q:Which company needs the new refractories?
The power plants are mainly used in steel plant, lime kiln, coking plants, boilers, etc. I will try my best to answer what I can. There are too many glassworks. You can tell me more anout what you need. As long as there is a large kiln business, the refractories and aluminum manufacturer are needed.
Q:Which kind of refractory floor is easy to use? ?
Fireproof wood floor includes three types, and according to your requirement, I think that the third type is more suitable or is easier to use. Here are the three types, and you can choose form them. A. Wear-resistant composite solid wood floor It is also known as super durable multi-layer solid wood floor. Its surface is inorganic glass fiber material and special paper impregnation thermosetting amino resin, composited with solid wood base materials like plywood or core-board. And also, its front is wear-resistant layer while the back is balance layer, then hot press it into grooved and tongued floor. This is a new impregnated paper laminate floor. It also has the same wear-resistant quality as laminate floor, comfort as solid wood floor, and stability as composite board. B. Fire-resistant wood-plastic composite decking board Wood-plastic composite decking board is not the wood floor in the traditional sense, but a composite material, also known as plastic wood. It is formed by high molecular improving and processing natural fiber, such as recycled plastic and wood fiber. It not only has the same advantages as plastic and wood, but alos has certain fire resistance, thus it is a environmentally friendly material with much development potential. C. Fireproof strengthened composite wood floor It is the so-called fireproof and fire retardant floor, fiber board, plywood and chipboard as its base materials. It is coated with fireproof coating and impregnated paper, and after fireproof and fire retardant technical process, it becomes a composite wood floor with some fire retardant level. Its features are more partial to that of laminate floor with stable performance, steady structure and good durability.
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).
