1.Steel Rolling Process
Hang qualified raw material to the feeding roller bed by crane, convey to the heating furnace tail, push to the heating furnace to heat by steel pusher. When material is heated to 1100-1200℃, it will be pushed out by discharge machine to rolling mill to be consecutively rolled 9 to 19 times. In order to prevent the rolling accident caused by irregular parts and low temperature parts, set rotary cutting flying shears between rough rolling(φ450×3+Φ450×2×2)and middle rolling(φ320×2×3), middle rolling and finishing I rolling(φ280×2×2). In order to minimize the processing time of rolling accident, set tensile shears and cutting shears before the hot material entering the mill entrance and finishing II rolling(φ280×2×3). Of course, the two rotary cutting flying shears also have the function, in order to ensure products quality and easy adjustment, set side movable sleeve and vertical movable sleeve between middle rolling and finishing I rolling, finishing I rolling and finishing II rolling.
Products rolled by the mill are sent by the pinch roll to rotary double-rule flying shear to be cutted into double-rule, then enter into upper steel pusher cooling bed to be cooled through clip tail roller after reducing the speed. When the products on the cooling bed surface step by step, in the meanwhile, the evener on the bed surface evens the products’ front, gather the products into collection agencies by dynamic tooth. When the products have been collected a certain quantity, collection agencies will translate them to under the table to be cut into scale, passing by the products inspection gathered in the products collection device, then packing, weighing, signing and piling in the storage.
