Practice of Hot-conveyance/Hot-charging of CC Round Billet to Pipe-rolling Process and Discussion on Related Issues

Detailed in the article are the process of hot-conveyance/hot-charging of the CC round billet to piperolling and related equipment as well as the trial activities of the said process.Accordingly relevant issues need to be studied and discussed are put forward here.The analysis reveals that the round CC billet hot-conveyance/hot-charging process features remarkable energy-saving efficiency, being applicable to pipe-rolling mills with single pipe type or few pipe types(one to four types)and a yearly capacity ≥ 250, 000 tons.The author regards that research and application of the technology of hot-conveyance/hot-charging of CC round billet to pipe-rolling process are worth using as reference for eliminating relevant conventional backward technologies, particularly in the present situation of the domestic steel industry involving cutting excessive capacity, upgrading, realizing sustainable development, and preventing repeated low-level constuctions.
