Steel drawing control method and device for hot rolling production line

Abstract

The invention provides a steel drawing control method and device for a hot rolling production line, and relates to the technical field of steel hot rolling. The method includes the steps that control signals of the hot rolling production line are monitored, operation time of technological processes on the hot rolling production line is obtained, and scheduled time from the moment when a first plate blank is drawn out of a heating furnace to the moment when a second plate blank is drawn out of the heating furnace is determined; experience operation time of the technological processes corresponding to varieties of the first plate blank and the second plate blank is obtained from a plate blank technological process database; experience time from the moment when the first plate blank is drawn out of the heating furnace to the moment when the second plate blank is drawn out of the heating furnace is determined; preferred drawing time of the second plate blank is determined according to the scheduled time and the experience time; and the second plate blank is drawn out of the heating furnace according to the preferred drawing time of the second plate blank. Through the steel drawing control method and device, the problems that since the steel drawing rhythm of the hot rolling production line is controlled through manual judgment at present, the idle running time of equipment is prone to being long, product quality is affected, and loss of the equipment and loss of power are caused are solved.

Description

Technical field [0001] The invention relates to the technical field of steel hot rolling, in particular to a method and device for controlling steel drawing in a hot rolling production line. Background technique [0002] Hot rolling refers to rolling steel above the crystallization temperature of the steel. Due to the low energy consumption of hot rolling, high metal plasticity, and improved processing performance of metals and alloys, hot rolling has been widely used in the production of steel materials. [0003] Current hot rolling production lines generally include such figure 1 The heating furnace 11, the rough rolling mill 12, the finishing rolling mill 13, and the coiling machine 14 are shown. The heating furnace 11, the rough rolling mill 12, the finishing rolling mill 13, and the coiling machine 14 are connected by a roller table 15 to convey steel. In the hot rolling production line, a large number of steel slabs 16 need to be drawn out from the heating furnace 11 and com...
