graphite electrode price per ton

The crucible is made of crystalline natural graphite as the main raw material and plastic refractory clay as the binder. It is made with different types of clinker and is mainly used for smelting special alloy steel and melting non-ferrous metals and their alloys.

In terms of product performance and use, graphite crucible is an integral part of refractory materials. how much is graphite electrode price per ton and about the graphite crucible, we will description on this article.

Graphite crucible

Crucibles can be divided into three categories: graphite crucibles, clay crucibles and metal crucibles. Among the graphite crucibles, there are three kinds of general graphite crucibles, special-shaped graphite crucibles and high-purity graphite crucibles. Various types of graphite crucibles, due to different properties, uses and conditions of use, the raw materials used, production methods, process technology, and product specifications are also different.

The main raw material of graphite crucible is crystalline natural graphite. Therefore, it maintains the original physical and chemical properties of natural right ink.

That is: it has good thermal conductivity and high temperature resistance, and has a small thermal expansion coefficient during high temperature use, and has a certain strain resistance to rapid heat and cold. It has strong corrosion resistance to acids and alkaline solutions, and has excellent chemical stability.

The crucible has many models and specifications, and it is not restricted by the production scale, batch size and smelting material variety during application. It can be selected at will, with strong applicability, and can ensure the purity of the smelted material.

Graphite crucibles are widely used in the smelting of alloy tool steels and the smelting of non-ferrous metals and their alloys in metallurgy, casting, machinery, chemical and other industrial sectors due to the above-mentioned excellent properties. And has a good technical and economic effect.

The types of crucibles are roughly divided into three categories: the first type of copper smelting crucibles, its specifications &; number&;; the second type is copper alloy crucibles, the special round has 100 numbers, and the round has 100 numbers. The third type of crucible for steelmaking has 100 numbers.

Crucible specifications (size) are usually expressed by the size of the serial number. Crucible No. 1 has a volume capable of melting brass, and its weight is 180g. The melting amount of the crucible when smelting different metals or alloys can be calculated by multiplying the corresponding metal and alloy coefficient by the specific weight of the crucible.

The raw materials for the production of crucibles can be summarized into three types. One is crystalline natural graphite, the other is plastic refractory clay, and the third is calcined hard kaolin-like skeleton clinker. In recent years, high-temperature-resistant synthetic materials such as silicon carbide, alumina emery and ferrosilicon have been used as the skeleton clinker of the crucible. This clinker has a significant effect on improving the quality of crucible products, enhancing the density and mechanical strength of the crucible.

There are three methods for crucible molding. The primitive and ancient molding method is hand molding. The second is the rotational molding method and the third is the compression molding method.
