Skateboard brick classification

Skateboarding refractory bricks are casting function, widely used in electric furnace, converter, ladle refining furnace and continuous casting tundish slide gate system. As molten and flow control switch mounted on the bottom of the ladle and tundish, exposed to a high temperature of about 1600 ℃ chemical attack of the molten steel, and a pressure of dozens or even hundreds of tons of liquid per ton of time. Therefore, the requirements skateboard brick with high temperature strength, excellent corrosion resistance, anti-erosion resistance and thermal shock resistance.

Meanwhile, in order to realize the function of opening and closing the flow of steel, brick skateboard sliding surface flatness and parallelism and dimensions must strictly comply with the requirements. Skateboard brick quality directly affect the safety of steel equipment and field operations personnel in the event of skateboard switch failure, rupture and other accidents, resulting in an outflow of molten steel, the consequences could be disastrous.

Material skateboard into high aluminumbrick, aluminum carbon, aluminum zirconium carbon three kinds; divided by the production process is not dipping, dipping, retorting three kinds; By physical and chemical indicators into HBL-55, HBLT-65, HBLT-70, HBLT-75, HBLTG-65, HBLTG-70, HBLTG-75 7 grades.

Wall insulation materials

Wall insulation materials currently available production equipment is mainly divided into two types: one is ordinary powder mixer, the second is dedicated external wall insulation mortar equipment. Both devices have advantages and disadvantages:

Do Wall insulation materials Wall insulation materials are aware of the mixing process was very strict, if the material is uneven mixing or higher breakage rates, will affect the insulation properties of the material. General powder mixer mixing equipment can also be used as wall insulation materials, but only mixed general Wall refractorymaterials, produced by the external wall insulation performance insulation products generally, construction of residential insulation performance requirements of applicable.

The single wall insulation mortar equipment such as inorganic hollow glass beads equipment, is designed for mixing equipment glass beads, glass beads stirred such equipment is the best equipment. Its high mixing efficiency, the use of double-cone breakage rate is relatively low, the production of insulation materials is the best. Currently much of this equipment manufacturers, domestic production is only so few. As people continue to attach importance to energy saving, new wall insulation mortar equipment will gradually be widely promoted.

In short, the wall insulation mortar compared with traditional dry mixer devices with high mixing efficiency, no broken material does not affect the physical properties of materials, etc., is the ideal equipment external insulation materials.

Application of graphite in the industry

Analysis of graphite, in addition to determination of fixed carbon content, it must also determine the content of volatile matter and ash at the same time.

Graphite is widely used in industry for the production of high-temperature smelting crucible on the industrial machinery lubricants,

making the electrodes and pencil; widely used in advanced refractory and metallurgical coatings industry, military industrial explosive materials stabilizers, light industry the pencil lead, carbon brush electrical industry, electrode in battery industry, fertilizer industry catalyst. Graphite after processing, but also to produce graphite, graphite sealing materials and composite materials, graphite products, high-technology refractory graphite friction reducing additives and other high-tech products, has become an important non-metallic mineral raw materials in various industrial sectors.
