● Pusher type reheating furnace to reduce investment.
● Semi-continuous rolling process. One stand of horizontal 2-Hi reversing mill, one stand of edger or two stands of 3-Hi mills for rough rolling, Finishing train consisting of two stands of edger and 8-9 stands of horizontal mills, of which 5-6 stands are 4-Hi stands.
● Edger with hydraulic AWC in roughing area and finishing rolling stands with hydraulic AGC.
● Water jet descaler to remove scales, located after furnace and before finishing rolling mill.
● Heat retention hood between rough rolling and finishing rolling stands to avoid temperature difference between head and tail of the middle part of the rolling stock after roughing rolling.
● Vertical looper to realize non-tension rolling at finishing stands.
● Hydraulic quick roll-changing device.
● Vertical coiler to reduce investment.
