Non-Metallic Minerals & Products

The graphite crucible for vacuum smelting of our company's intermediate frequency furnace is based on imported needle coke, three high graphite crushed and high-quality modified asphalt as the main raw materials. After firing at a predetermined temperature rise curve, it is then impregnated with high pressure, re-fired, and then graphitized at a temperature above 3000 ° C. The ultra-high power graphite crucible has the characteristics of compact and uniform structure, high strength, low resistivity, good thermal conductivity and high bulk density. It is widely used in high-frequency smelting of medium frequency furnaces, copper, copper alloys and non- ferrous metals. Product specifications: diameter Φ500 ～ 710 mm, height 500 ～ 1300 mm, smelting capacity 500 kg ～ 5000kg. 1.Handle with care during transportation, handling, and storage.

Ultra High Power Graphite Crucible Ultra-high power graphite crucible has the characteristics of high temperature resistance, strong thermal conductivity, good corrosion resistance and long service life. In the process of high temperature operation, the coefficient of thermal expansion is small, and it has certain strain resistance to quench and heat. It has strong corrosion resistance to acidic and alkaline solutions and excellent chemical stability. It does not take part in any chemical reactions in the smelting process. The inner wall of graphite crucible is smooth, and the melted liquid metal is not easy to leak and adhere to the inner wall of crucible, which makes the liquid metal have good fluidity and castability. In metallurgy, casting, machinery, chemical industry and other industries, it is widely used in the smelting of alloy tool steel and the smelting of non-ferrous metals and their alloys.   Product Specification Brandname diameter(mm) Height(mm) Upper bore inner diameter(mm) Bottom bore(mm) lnternal height(mm) SY-I 710 1360 570 540 1240 650 1360 540 510 1240 600 1280 490 460 1160 Description: S stands for plastic forming mode, Y stands for abnormal shape, l for melting copper, preciousmetals and rare earth alloy crucibles.

Honeycomb Filter also named Ceramic Honeycomb Filter.It is produced based Mullite with kinds of hole sizes, which can withstand heavy pouring thermal shock and extreme pouring temperature.  The cellular design also provides an engineered balance between flow rate and strength and it can effectively capture inclusions and reduce turbulence of the molten metal.  Functions of Ceramic Honeycomb Filter The straight-pore honeycomb ceramic filter has the characteristics of large specific surface area, high strength, and thermal shock resistance. The following effects can be achieved through internal filtration: Purify molten metal and remove non-metallic impurities and gases; Make the metal liquid filling stable and reduce the whirlpool; The honeycomb ceramic filter can simplify the pouring system and improve the process yield; Reduce casting pores, optimize and refine metal structure; Improve the surface quality and mechanical properties of castings; The honeycomb ceramic filter can reduce the scrap rate of castings; Reduce machining allowance and increase tool life, reducing casting cost.  Advantages of Honeycomb Filter 1.It has very high working strength at high temperatures, thermal shock resistance, and metal flow impact resistance. There is no slag or cracking phenomenon during operation, which ensures the filtering quality of molten metal. 2. The honeycomb ceramic filter has a large metal flow rate, and the flow rate is stable. Even in the case of a large number of inclusions in the molten metal, normal use will not cause blockage of the filter. 3. With very high dimensional accuracy, it can be used in the production line of automatic filter placement. 4. The honeycomb ceramic filter has extremely high normal temperature strength and mechanical shock resistance. There is no rupture or damage during use and transportation, which greatly facilitates the use and operation of the filter.
