In the 1980s, due to the short supply of carbon products and the high profit rate of carbon products, carbon enterprises generally had good economic benefits, and carbon enterprises rose rapidly throughout the country. However, due to the lack of advanced automatic carbon component, the whole carbon industry scale is small, it is difficult to form effective competitive power. In addition, there is excess capacity of low-end products, insufficient supply and demand of high-end products, and unreasonable carbon industry structure. The development prospect of carbon plants is closely related to the process of high-tech carbon automatic batching.

　　The raw materials of carbon equipment and carbon products are carbon raw materials. Their chemical structure, morphological characteristics and physical and chemical properties are very different due to different sources and production techniques. According to the physical state can be divided into solid raw materials (aggregate) and liquid raw materials (adhesives and impregnators).

Among them, the raw materials of carbon products can be divided into: more ash raw materials and less ash raw materials according to the content of inorganic impurities. The ash content of low ash raw materials is generally less than 1%, such as petroleum coke, asphalt coke, etc. The ash content of polyash raw materials is generally about 10%, such as metallurgical coke, anthracite and so on. In addition, the return materials in production, such as graphite crushing, can also be used as solid raw materials. Due to the different roles and uses of various raw materials, their quality requirements are also different.
