Large graphite crucible(with spout) are mainly used in metallurgy, chemical industry, glass and other fields of various powder sintering and metal smelting, and are often used in papermaking industry for dehydration and various grinding components. It is an ideal ceramic substitute. Advantages of Graphite Rod Electrode î?? Large graphite foundry crucible has strong corrosion resistance against acid and alkaline solution. Semiconductor graphite crucible can be used in high temperature systems, for some strong strain resistance of the product, it also has the chemical stability, so that its thermal conductivity is satisfactory. How to Use graphite crucible for sale î?? 01 Before use, bake slowly in the oven to 500â??; Place in dry place after use to avoid rainwater intrusion. 02 According to the capacity of the crucible, do not squeeze too tightly, so as not to crack the crucible due to the thermal expansion of the metal. 03 When removing the molten metal, scoop it out with a spoon and useless caliper as much as possible. If the use of calipers and other tools, should be consistent with the shape of the crucible, so as not to local stress too large, shorten the service life. 04 The service life of the crucible is related to its use. Strong oxidation flame should be avoided to spray directly on the graphite crucible to shorten the service life of raw materials.
