Silicon Carbide Graphite Crucible

    Product Name: Silicon Carbide Graphite Crucible

    Silicon carbide graphite crucible is an indispensable high-temperature smelting container for production operations in industries such as aluminum alloy casting, copper alloy smelting and casting, precious metal (gold, silver, platinum, rhodium, palladium) smelting and purification, electronic waste smelting, lead-containing waste battery treatment, rare earth and oxide smelting and purification, zinc and zinc oxide evaporation, etc.

     

    Before 2006, the smelting crucibles commonly used in the above-mentioned industries were pressureless spin-molded products that were a combination of graphite electrode processing products and clay. The products had a short service life, poor thermal conductivity, and serious pollution to the smelted metal. After 2007, domestic technicians successfully developed and produced silicon carbide graphite crucible products that used phenolic resin as a binder and were formed by an isostatic press, referring to the production technology of aluminum-carbon refractory materials for steel continuous casting. After being put on the market in batches, the application scenarios of the above-mentioned domestic markets have undergone subversive changes.

    The silicon carbide graphite crucible products, which use phenolic resin as a binder and are formed by an isostatic press, use high-purity silicon carbide and natural flake graphite as the main raw materials, use phenolic resin as a binder, and are formed by an isostatic press. The product has a large and very uniform volume density, excellent thermal conductivity, good oxidation resistance, and strong resistance to high-temperature chemical corrosion of various refining agents and slag-breaking agents. In just over a decade, it has become an indispensable leading product in market applications.

     

    The main process flow of our company's products is as follows:

    Batching - pretreatment - mixing and granulation - mud drying - isostatic press molding - shape processing - blank drying - anti-oxidation coating coating - firing - testing and packaging

     

    At present, we can provide 67 mainstream specifications and varieties on the market. Its standard structure is divided into three crucible series: standard, reinforced and professional grade. Various materials can professionally adapt to the different needs of various heating methods such as flame furnaces, electric furnaces, electromagnetic induction furnaces (induction metal and induction crucibles). Compared with the products of other major suppliers on the market, BETTER CARBON's products have better thermal conductivity, stronger thermal shock stability, less thermal conductivity decay with the extension of use time, and will not be corroded by substances contained in the fuel even when used in biomass pellet furnaces. Because it contains almost no "silicon", it will not cause "silicon pollution" when smelting special high-purity alloys.



    INQUIRY

Isostatic graphite crucible features:

Long life: a dense body is formed under high pressure, and its service life is 3 to 5 times longer than that of traditional clay crucibles;

Fast thermal conductivity: high-density green body and low apparent porosity greatly improve the thermal conductivity of the crucible;

New materials: The use of new thermal conductive materials ensures high heat transfer and pollution-free performance of the product, and effectively reduces sticky residue;

Corrosion resistance: Compared with clay crucibles, it has stronger corrosion resistance;

Anti-oxidation: The advanced technology is used to increase the antioxidant capacity of the blank, ensuring the product's long-lasting thermal conductivity and long service life;

High strength: High pressure body and reasonable structure make the product have excellent pressure bearing performance;

Environmental protection: Its characteristics of high efficiency, energy saving and no pollutants not only ensure the purity of users' products, but also do not affect the ecological environment.
