Problems solved by technology

[0002] During the hot continuous rolling of stainless steel, when the hot-rolled strip arrives, if the edge heater fails and is not turned on in time, it will cause the strip to enter the edge heater area due to the high speed of the rolling line and the failure to prevent the strip from entering the edge heater area in time. Cause the strip to hit the edge heater

Embodiment Construction

[0009] Shanxi Taigang Stainless Steel Co., Ltd. hot continuous rolling rough rolling, finish rolling two zone roller table speed control handover point is 10 meters before the finish rolling flying shear, the strip handover speed is 2m / s, and the position of the edge heater is at The position 9 meters before the finishing rolling flying shear. Due to the inertia of the strip steel and the existence of tracking control deviation, if the strip steel passes at the transition point of rough rolling and finish rolling control at a speed of 2m / s, once the side heater equipment fails and the rough rolling exit roller table is requested to wander, the strip will Steel will rush into the edge heater area and damage the edge heater equipment. Therefore, under the premise of ensuring normal rolling, redesign the advance control of the deceleration point of the roller table and reduce the speed of the strip handover point so that the rough rolling exit The strip will not damage the edge h...

Abstract

The invention belongs to the field of automatic control of hot continuous rolling strip steel rolling lines and particularly relates to a method for protecting edge heaters during hot rolling of stainless steel. A first metal detector, a second metal detector and a third metal detector are installed on a roller way from a roughing mill to a connecting point of the roughing mill and a finishing mill, edge heaters are installed on two sides of the roller way behind the connecting point of the roughing mill and the finishing mill, during hot rolling of the stainless steel, strip steels move from the roughing mill to the finishing mill along the roller way, first-stage speed reduction is conducted when heads of strip steels move to the first metal detector, second-stage speed reduction is conducted when heads of strip steels move to the second metal detector, and when heads of strip steels move to the third metal detector, if edge heaters detect abnormalities, strip steels moving on the roller way are subjected to wandering control till strip steels return to normal conditions. By the aid of the method, the safety usage of edge heaters during rolling of the stainless steel is guaranteed.

Description

technical field [0001] The invention belongs to the field of automatic control of hot continuous strip steel rolling line, and in particular relates to a method for protecting edge heaters in the stainless steel hot rolling process. Background technique [0002] During the hot continuous rolling of stainless steel, when the hot-rolled strip arrives, if the edge heater fails and is not turned on in time, it will cause the strip to enter the edge heater area due to the high speed of the rolling line and the failure to prevent the strip from entering the edge heater area in time. Cause the strip to hit the edge heater. Contents of the invention [0003] The technical problem to be solved by the present invention is: how to solve the safe use of the equipment of the side heater when using the side heater in rolling stainless steel. [0004] The technical scheme adopted in the present invention is: the method for edge heater protection in the stainless steel hot rolling proces...
