BOF taphole slag slide gate mechanism
Using the mechanism of BOF slag could recovery slag effectively in the furnace. And slag splashing protection technology could increase converter furnace which can solve the problem of irregular erosion in taphole. By the new process of slag controlled tapping , can improve the alloy yield, and can also greatly save the amount of aluminum addiction, the comprehensive cost reduction is considerable, and it also improved the economic efficiency and the competitiveness of the products in the market, it’s the first choice of equipment for smelting high quality steel.
Medium or high temperature sintered Sialon bonded sliding gate at N2 atmosphere
Independent research and development of new sliding gate by importing special sialon additives, sintering at the medium our high temperature of N2 atmosphere. In the process of sintering create the sialon phase with good medium or high temperature performance, thus improved the high temperature compression strength and the breaking strength. The using effect on the large and medium-sized steel ladle and the tundish is good.
Converter Tap Hole Stopping-Slag Slide Plate
Pure zirconia plate is inlayed in the important region of converter tap hole stopping-slag slide plate. The matrix is made of stable medium and high temperature AZC materials，which has long service life, excellent effects of stopping-slag.
- Q: How long is the fire resistant limit for ultra thin fire retardant coating?
- The fire resistant limit of ultra-thin fire retardant coating is 1.5 hours, generally fire resisting time for thin fire retardant coatings does not exceed 1.5 hours. If the time exceeds 1.5 hours, thick fire resistive coating should be uesd. There is no detailed stipulation for ultra-thin fire retardant coating, and the thickness of the inside is the fire resistance limit shall reach certain time(at least). If fire resistance limit is 2.5 hours, the thickness shall be 4.9mm. If the fire resistance limit is 2 hours, the thickness is 3.5mm. If fire resistance limit is 1.5 hour, the thickness should be 1.75mm.
- Q: What does the function of SiC for refractories?
- Anti-wear! High intensity!
- Q: Please answer the questions about the packing and transportation requirements of refractory materials.. Requirements for packing of refractory bricks
- First of all, customer requirements, packaging according to customer requirements. According to the packaging packaging tray packaging is divided into 40 yuan / tons, carton 70 yuan / tons, 40 yuan / ton, straw packing bags of 30 yuan / ton.
- Q: What kind of refractory materials can withstand 1500℃ when processing briquette stove core and meanwhile cost less?
- Alkali resistant castables cost the least.
- Q: What's the refractory material in common use currently?
- (1) Alumina-silica refractory brick: Except the transition band, hot end and firing zone of the rotatory cement kiln, it can be applied to the whole burning system of the precalcining kiln, such as the fixed wall lining, wicket, cooling machine, tertiary air duct, burner, etc. It mainly includes alkali-resisting brick, high alumina (anti stripping) brick, silica-mullite brick, etc. (2) Basic refractory: For the upper transition band close to the part of burning zone and the burning zone, its inner lining can endure the highest flame temperature of 2000℃ and material temperature of 1350℃-1400℃, and it also has to withstand the permeation of sulfur and alkali compounds, permeation, thermal shock and oxidoreduction of hot-melt clinkers (liquid phase), mechanical stress of elliptic cylinder deformation, etc. Therefore, inner linings are the most demanding parts to withstand stress, and only basic refractory can meet with requirements under this working condition. (3) Fireclay insulating refractory: Its microstructure has notable characteristics of high porosity, large pore size and thermal insulation performance. For its low volume density and light weight, it is usually referred to as lightweight refractory. Fireclay insulating refractory product has great varieties, and it is usually classified and named according to its chemical and mineral compositions or production raw materials, and it is also classified according to its operating temperature and material form. Currently, the most used main thermal insulation material for the precalciner kiln system at home and abroad is calcium silicate board; besides, light weight castable and insulating fire brick are increasingly used year by year. Other thermal insulation materials are mainly ceramic fiber products.
- Q: How long is the fire-resistant time of fireproof wooden door?
- Wooden thermal insulation fireproof door using flame-retardant timber or flame-retardant timber products to make door frames, skeletons of door leaf, door panels. If the door leaf need to be filled with materials, the filling materials should be fireproof thermal insulation materials which is non-toxic and harmless to human body, and matched fireproof door composed of fireproof hardware. Use doors without age limits.
- Q: What is the particle size of boron carbide for refractories?
- 2 floor is right, support, learning! But what do you mean by boron carbide (d90=36.5, m)?
- Q: Does the aluminum silicate thermal insulation material fireproof?
- it can be fireproof and has a strong fireproof?performance.
- Q: Which fireproofing materials factory is the best in Xiangyang?
- Of course, it is "Lvchuang Construction Energy Saving Engineering Co., Ltd." in Xuzhou, which main products are A-level fireproofing thermal insulation boards. It has many projects. B1-level fireproof materials are polyphenyl boards, extruded sheets, phenolic foam boards, Polyurethane board, sea capacity building energy efficiency module. Flame retardant has been added to the sea capacity building energy efficiency modules which has a B1-level fireproofing performance. You can also add expanded glazed hollow beads to them if you are worried about the security.
- Q: What's the fire endurance of A grade fireproof glass curtain wall?
- An hour and a half, an hour, and half an hour. As a key step in the home fire prevention, fire door is particularly important. According to the fire endurance and heat insulation performance, it can be classified as follows: A class fire door with fire endurance of no less than 1.5h; B class fire door with fire endurance of no less than 1h; C class fire door with fire endurance of no less than 0.5h. We can choose according to different needs, while A class fire door and B class fire door are now commonly used. Fire door has great varieties, and the material it uses is also of wide range. It includes stainless steel fire doors, glass fire doors, steel fire doors, etc. The most important feature of fire door is its fire resistance period. The main difference between A class fire door and B class fire door lies in their fire endurance, of which the former is no less than 1.5h, while the latter is no less than 1h. Difference between A class fire door and B class fire door also lies in their fireproofing material. That is the thickness of the built-in fire prevention board, of which A class fire door is 52mm, while B class fire door is 46mm. Therefore A class fire door obtains longer fire resistance period than that of B class fire door and gains better fireproof performance. A class fire door and B class fire door also differ in the places they are used. A class fire door is generally used in important fire fighting access of machine rooms, warehouses and oil depots, etc. and flammable and explosive public places, while B class fire door is generally used in the ordinary fire fighting access of some ordinary buildings. But B class fire door is more widely used than A class fire door.
