Description Graphite Casting Melting Crucible 4KG Gold Silver Scrap Casting Mould Melt Specification Material GraphiteCapacity 4KGHeight 130mmTop Diameter 85mmBottom Diameter 75mmQuantity 1pc Application Graphite crucible is generally used in alloy tool steel smelting and smelting of nonferrous metals and their alloys Graphite crucible can be used in the processing of graphite graphite crucible graphite casting crucible tank pull rods mold and other graphite products Graphite crucible let the products are more durable than ordinary material products longer service life able to withstand more than 2000 centigrade high temperature Features Well thermal stability according to the using conditions of graphite crucible snap heat and cold Well corrosion resistance impact resistance performance to ensure the reliability of product quality Well resistance to strong acid strong alkali Good heat transfer performance of graphite crucible for greatly shorten the melting time and save energy Ash content less than 0 1 to ensure the precious metals in smelting is not contaminated In high temperature using process it got small thermal expansion coefficient And certain strain resistance to the thermal shock quenching Note Stored in dry place do not get it wet After drying the crucible dont make it touch with water Be careful not to give a mechanical impact force not from a fall or impact Package Included 1pc x Graphite Crucible More Details
