Introduction to the packaging steel strip production technology

Packaging steel strip production technology introduction to traditional high strength packaging steel strip production process there are generally two kinds of process, one is the lead bath isothermal quenching, bainite strengthen treatment, the other is to use cold rolled reinforcement, annealing process, the former because of lead pollution to the environment, countries began to restrict the use of, which require high quality of raw material and the quality is not easy to stability, the development is restricted. Packing steel strip production technology route of high strength steel strip production line using induction heating and tempering heat treatment process, process route for continuous casting billet > Hot rolled steel belt - > Cold rolled steel belt - > Slitting - > Put a roll - > Welding - > Entrance to the loop - > Trimming process - > High frequency heating - > Water quenching - > Tempering induction heating - > Heat preservation processing - > Apply wax - > Looping - for export > Steel strip coiling. Two steel belt production line parallel, quenching, tempering, blue series, can not only improve the production efficiency, and appropriate speed slows down the line, to facilitate workers operation, water quenching if stop using high frequency heating equipment, production line can be used in the production of blue packaging steel strip annealing line combination, expanded equipment using range, enhances the production enterprises to adapt to the market.
