Graphite block have high density and high conductivity, can be used for metallurgical casting and chemical industry. Such as metallurgical furnaces, silicon carbide furnaces, graphitization furnaces, chemical heat exchangers, etc. With high mechanical precision, it can be made into different shapes such as circles, rectangles, and trapezoids. The largest size that we can produce is: the maximum length of 2500mm,the maximum width of 600mm,and the maximum height of 600mm.
Three standard methods are used for production: molded, extruded, and isostatic pressing. Each process ensures the creation of high-density and uniform structures.
1. Molded: Compression molding is a transparent paste or pressed powder is placed into a mold of the desired shape and size. Under pressure, the particles interweave, resulting in a compact and durable block of graphite.
2. Extruded: The raw material undergoes pressure through the extrusion method as it passes through a die of a specific shape. Then compaction and plastic deformation produce with precise sizes and shapes.
3. Isostatic Pressing: We use isostatic pressing to create high-density, uniform structures. This unique manufacturing process involves subjecting the material to high temperatures and pressure. The result is the products with exceptional quality and durability. The manufacturing process cycle is generally longer, more than two months.
What are the uses of graphite block?
Used in Electrolysis: They are indispensable as conductive электроды in industries such as electrolytic metal, magnesium, nickel, and more.It has corrosion resistance, can resist the erosion of chemical media such as acids and alkalis, and maintains stable performance.
Металлургические печи и печи сопротивления: They used in металлургические печи, печи сопротивления и другие применения, где важны высокотемпературная стойкость и проводимость.
Химическая промышленность: They excel as furnace materials for corrosion-resistant heat exchange equipment and high-temperature furnaces. Large graphite block heat exchanger can meet the strict requirements of the chemical industry. Because they have higher specific resistance.
Foundry industry: It can be made into graphite mold for casting and smelting. Because its ultra-high density and compact structure are very suitable for smelting gold, silver and other precious metals.
Aerospace industry: They are resistant to high temperatures, light in weight, and high in strength. Therefore they are widely used in the aerospace and military industries.
