At present, it has built many production lines such as stamping, spot welding and spraying, and more than 150 sets of various production equipment. Focusing on the processing and manufacturing of household appliances and automobile sheet metal parts, the company focuses on cultivating professionals in mold design and manufacturing, mechanical and electrical equipment maintenance, material forming and coating of foundry platform manufacturers. The company has all kinds of senior technical management personnel more than 50 people, nearly 600 technical workers. The establishment of sheet metal parts supporting base facing the northern market can effectively promote the leapfrog development of light industry in Handan, and drive the local economic development and social employment. Annual production of more than 1.5 million tons of high purity pig iron, high quality ductile pig iron and castings. The annual sales revenue is more than 5 billion yuan, the assets of 1.7 billion yuan, is excellent casting refers to the quality cast iron production base enterprises set up the Chinese foundry association. The P content of pig iron was reduced from <0.03% to <0.02% by further developing the low cost P removal process. (2) The sinter with particle size less than 10mm accounts for 45%. If the FeO content is increased, the fuel consumption will be increased and the reductionability will be reduced. Therefore, it is necessary to develop high sinter with low FeO, high strength and particle size to meet the needs of iron making. Problems to be solved: the complete sheet metal technology of parts in GC series air conditioner cabinet is expected to get technical support and help from experts.
