Graphite mould is used in the fields of national defense, machinery, metallurgy, chemical industry, casting, non-ferrous alloys, and lightening, especially black carbon rods. It is also used in the fields of ceramics, semiconductors, medicine, environmental protection, laboratory analysis, etc. metallic material. When cutting steel, it is not necessary to use flammable and explosive gases like oxygen-acetylene flame cutting, which has low cost and safe operation. You can use arc cutting to process a variety of metals that cannot be processed by gas cutting, such as cast iron, stainless steel, copper, aluminum, etc., with high efficiency, and all can get more ideal results. Performance: The component is hard and brittle, has a small expansion coefficient, can withstand rapid cooling and heat, is not easy to deform, has good chemical stability, has strong acid resistance, does not react with strong acids, has poor alkali resistance, and can corrode at high temperatures.

Graphite jewelry molds make original designs of graphite crucibles attached to them for a long time, which keeps high-temperature resistance. Making graphite molds for jewelry is the procedure used to insure that jewelry items can be accurately duplicated at any time future. The mold making process begins with the creation of a metal model. Models can be as simple as a basic ring or complex as jewelry containing multiple interlinking parts used to create elaborate multicolor jewelry. What's the difference between graphite ring molds and metal ring molds? Custom graphite molds for glass, while less costly and more resistant to warping under high temperatures compared to metal counterparts, may impart a slightly rougher finish to the glass ring. This difference in finish arises from the inherent properties of the materials; graphite tends to have a slightly coarser texture than metal. However, graphite molds excel in thermal stability and are often preferred for their durability and longevity in glassmaking processes. Conversely, metal ring molds, such as silver casting molds, offer a smoother finish but come with a higher price tag and susceptibility to deformation under extreme heat. Glass artisans weigh these factors when selecting between graphite and metal ring molds, balancing cost, durability, and desired surface finish in their creative endeavors.
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.

Pure graphite is a mineral form of the element carbon (atomic number 6) and its symbol is c. It forms in veins in metamorphic rocks as the result of the metamorphism of organic material included in limestone deposits. It is an extremely soft mineral at 1 to 2 on mohs' hardness scale. It is black and has a black streak. (streak is the color of a mineral when it is crushed to a powder). Its softness and streak make graphite useful in making f+leadf+ for pencils. Crystals are uncommon, but when they occur, they are found as rough, six-sided (hexagonal) flakes. It breaks into minute, flexible flakes that easily slide over one another. Mineralogists call this basal cleavage. This feature is the cause of graphite distinctive greasy feel. It is this greasy characteristic that makes graphite a good lubricant. Because it is a solid material, it is known as a dry lubricant. Graphite is the only non-metal element that is a good conductor of electricity. 25kg/bag;1 ton.Kraft bag.20ton/20fcl.
