process abstract

The hot billet is directly sent to the hot rolling mechanism by hot charging roller table through induction heater.The hot charging line is of that cold billet lifted to charging roller table by the crane and sent to the reheating furnace end. Then pushed into the reheating furnace by billet pusher and after the temperature reaches 1150~1250℃,pushed the hot billet out of the furnace by billet out machine. It enters the two-roller reversible rough rolling mill of Φ480×1×2 through furnace out roller table and roller table before machine and rolled for 6passes. After cutting the irregular parts in the head, it enters intermediate rolling mill of Φ380×2×3 for continuous casting. Set a repeater among the Φ380×2 intermediate rolling mill groups, make the rolling line shift to the next bay.

The products from Φ380×2×3intermediate rolling mill enter the finish rolling mill groups of Φ300×1×6 for continuous rolling after cutting the irregular parts by 2#end-cropping flying shear. In order to improve products' quality and adjust easily,a set of vertical loop is set among the Φ300 finish rolling mill.

The final products from finish rolling mill cut to multiple length by multiple length flying shear, and enter the cooling bed entering device through speed-up roller table and cooling bed entering roller table , and sent to cooling bed by the cooling bed entering device for cooling. The after-cooling products transferred to cooling bed output roller table from cooling bed exit device and sent to final products cut-to-length flying shear for cut-to-length.
