A billet picking method for continuous casting and rolling production line

Abstract

The invention discloses a billet picking method for a continuous casting and rolling production line. After the transportation of the slab stops, the first cutting device installed at the position corresponding to the fixed section and the movable section of the heating furnace enters the heating furnace, and is installed at the same time The second cutting device at the position corresponding to the exit of the heating furnace approaches the slab, and the slab is cut by the first cutting device and the second cutting device to obtain a slab to be rejected that is trapezoidal in shape and whose removal side length is greater than the non-removal side length , the slab to be rejected is located in the movable section; the movable section starts to move, and moves to the movable section to dock with the roller table; the movable section transports the slab to be rejected to the roller table, and the roller table moves the slab to be removed out Continuous casting and rolling production line. After the slab is cut, it directly moves together with the movable section, without the need for the operator to go to the cutting site to confirm, and to manually adjust the position of the slab to be removed. Compared with the traditional slab removal process, it saves labor and effectively shortens the slab removal time. Improve blank removal efficiency.

Description

technical field [0001] The application belongs to the technical field of thin slab continuous casting and rolling production lines, and in particular relates to a billet picking method for continuous casting and rolling production lines. Background technique [0002] At present, the domestic thin slab continuous casting and rolling production lines are equipped with single-line or double-line heating furnaces. The heating furnace is the key equipment connecting the continuous casting machine and rolling mill in the thin slab continuous casting and rolling production line. It is used for slab heating or for the production line. Buffer and heating furnaces mostly use roller hearth heating furnaces or electric induction heating furnaces. According to the fixing method of the furnace body, the furnace body can be divided into two parts: the fixed section that is fixed relative to the ground, and the movable section that can move relative to the ground. According to the way of m...

Problems solved by technology

As a result, the slab position adjustment workload is heavy, and the operator needs to be on site to take care of it, which consumes a long time, and the slab needs to be cut multiple times, and the removal efficiency of the slab is low
