Design Concep tand App licability Analysis of CC Round Billet Hot-charging Method and Operation System

Elaborated in the paper are the hot-rolled pipe-purpose CC round billet hot-chargingmethod and the operation system，involving design concept，process flow，major equipment selection，benefit calculation and app licability analysis，etc.The design concept of the said hot-charging method and operation system is as follows. Getting the steel pipe hot-rolling system and the steel-melting/CC system integrated into one system；real-time organizing the production and billet supply activities of the steel-melting/CC system according to the requirements by the steel pipe hot-rolling system；and having the two systems to bematched to each other in terms of hourly output and yearly output.The CC round hot-charging system will feature smooth and reasonable process flow.And the multiple-length CC billetwill be heated via twowalking-beam heating furnaces，i.e.the pre-heating furnace and the hi-temperature furnace，and then cut into specified-length pieceswith the high-speed，rotary hot-sawingmachine.
