Frequently Asked Questions
Lorem ipsum dolor sit amet,consectetur.
What is a graphite crucible?
+
-
A graphite crucible is a container made from high-purity graphite, designed to hold and melt metals at high temperatures. It's commonly used in foundries, refineries, and laboratories due to its resistance to heat, thermal shock, and chemical corrosion.
How are graphite crucibles made?
+
-
Graphite crucibles are manufactured by blending graphite powder with binders, then molding the mixture under high pressure. The formed crucibles are baked at high temperatures and sometimes coated to enhance oxidation resistance. At SHJ-CARBON, we use isostatic, molded, or extruded graphite based on the application's needs.
How long do graphite crucibles last?
+
-
Lifespan depends on usage conditions such as temperature, material type, and frequency of cycles. In most industrial environments, a high-quality graphite crucible can last anywhere from 20 to 80 melts. Proper handling and maintenance can significantly extend its life.
What's the maximum temperature your crucibles can withstand?
+
-
Our graphite crucibles can handle temperatures up to 3000°C (5432°F) in inert or vacuum environments, and around 1600–1800°C (2912–3272°F) in oxidizing atmospheres, depending on the grade and coating.
Can you customize crucibles for specific alloys or melting conditions?
+
-
Yes. We can tailor crucibles based on alloy type, temperature range, and furnace design. This includes adjustments in graphite grade, wall thickness, dimensions, coatings, and even pour spouts or lids.
