Feature: 1. Thermal Stability: Ingot casting tool is thermally stable, which can be heated and cooled quickly, and is resistant to strong acid and alkali corrosion, and is used for smelting metals such as gold and silver. 2. Electrical Conductivity: Melting ingot has thermal shock resistance, electrical conductivity and thermal conductivity, which is more conducive to metal smelting. 3. High Temperature Resistance: Graphite ingot mold has high temperature resistance. in the process of high temperature use, the thermal expansion coefficient is small, and it has certain strain resistance to rapid heating and rapid cooling. 4. Melting Metals: Metal Refining mould refine metals such as gold, silver, platinum and other alloys, which are durable and have a long service life and can be used for a long time. 5. Application: Graphite crucibles are widely used in experiments and metal smelting and industrial sectors, and are widely used in the smelting of alloy tool steel and the smelting of non ferrous metals and their alloys. Specification: Item Type: Ingot casting tool Material: Graphite Outer Diameter Size: Approx. 90 x 18 x 12mm / 3.5 x 0.7 x 0.5in Inner Diameter Size: Approx. 80 x 8 x 8mm / 3.1 x 0.3 x 0.3in Product Description: The graphite crucible smelting original material is crystalline ordinary graphite. Therefore, the original ordinary graphite with various physical and chemical properties is retained. Using special high purity graphite material, high strength, high density graphite material; excellent technical personnel; high accurate CNC processing equipment, etc., can provide customers with excellent graphite crucible smelting, casting crucible, graphite tank, pulling force , tie rods, molds and other graphite products performance. Using special special materials can make our graphite crucible products more than 2 times more durable than ordinary materials, longer service life, and more resistant to high temperatures above 2000 ℃!.
