High temperature resistance Refractory Graphite Sagger for N2 FIRING
High Density Refractory Graphite Sagger Box
Graphite Sagger box
Graphite sagger box is made of high quality graphite block and widely used in all kinds of furnace for melting such as jewelry, gold, silver, copper, brass, iron, aluminum, zinc, lead and so on. Based on working environment, we could supply the molded graphite, isostatic graphite, medium grain graphite, and some imported graphite materials.
● High Density, Low ash content, High purity ● High temperature resistance ● Oxidation resistance ● Strong acid and alkali resistance ● Strong thermal shock resistance ● Good electrical conductivity
molded graphite, isostatic graphite, medium grain graphite, and some imported graphite materials.
