Coil box equipment double-interlock protection device and control method thereof

Abstract

The invention discloses a coil box equipment double-interlock protection device, and belongs to the technology of steel rolling equipment. The coil box equipment double-interlock protection device comprises a pinch roll sensor (1) of a transmission side, a pinch roll sensor (6) of an operation side, a position roll sensor (2) of the transmission side, a position roll sensor (7) of the operation side, a 2L roller position roller (3) of the transmission side, a 2L roller position roller (8) of the operation side, a 1A roller position roller (4) of the transmission side, a 1A roller position roller (9) of the operation side, a 1B roller position roller (5) of the transmission side and a 1B roller position roller (10) of the operation side. The invention further discloses a coil box equipment double-interlock protection control method. The coil box equipment double-interlock protection device and the control method of the coil box equipment double-interlock protection device lay emphasis to solve the problem that detection failure of the sensors result in equipment damage or production halts when the hot rolling coil box works under a hot and humid severe working condition environment, can well relieve the time pressing stress caused by sudden failures of the coil box in the compact production process, and can guarantee the safety of equipment and continuity of production when the sensors are detected to fail to work.

Description

technical field [0001] The invention belongs to the field of steel rolling equipment, and in particular provides a double interlocking protection device for hot coil box equipment and a control method thereof. Background technique [0002] The hot coil box equipment is usually installed between rough rolling and finishing rolling, which is used to coil the intermediate billet sent from the rough rolling area at high speed, and then uncoil and send the intermediate billet to the finishing rolling line at low speed. However, the structure of the hot coil box equipment is complex, especially the roller systems such as pinch roller, position roller, 2L roller, 1A roller, 1B roller, etc. all require long stroke action. The movement stroke detection device is a number of SSI sensors installed on the transmission side ( MTS linear position sensor or encoder). [0003] When using the original equipment control, there are the following problems: the hot coil box works in a high temp...
