型焦在冲天炉中的应用（Application of shaped coke in Cupola） Keywords: cupola, casting coke, smelting In the modern casting production, are still used by most of cupola (alone or with the electric double), this is because the cupola has the advantages of low energy consumption, large quantities to meet the requirements of continuous production, simple structure and convenient operation etc.. With the development and progress of environmental technology, control technology and foundry technology, cupola melting to further expand. For a long time, the cupola furnace in China is fueled by metallurgical coke and local coke (also called soil coke), which seriously restricts the smelting technology and economic level of cupola, and becomes the key link in the production of cast iron parts. At the beginning of 1980s, China in the development and production of conventional coke oven coke made significant progress, the formation of a larger production capacity, produce all kinds of foundry, formulated the national standards, and has achieved significant benefits in application in foundry production. However, conventional coke oven production foundry (conventional foundry, the same below) is made of high quality coking coal as the main raw material, limited in resources. Coking time foundry metallurgical coke production at the same time than long more than doubled, so the production cost is increased. How to utilize the rich and high-quality anthracite to refine coke is the direction of the coking workers and the expectation of the foundry workers. With the development of coking technology, Formcoke technology is increasingly mature and perfect, it is a weakly viscous coal or anthracite as the main raw material with a small amount of coking coal and binder molding after carbonization furnace refining coking. 1. requirements of cupola smelting on coke The cast type Jiaozuo is the special fuel for cupola smelting. In the process of research and development, we must first understand its fun
