Device and method for calibrating zero positions of continuous casting-and-rolling high-speed flying shear rotating drum and equipment

Abstract

The invention discloses a device and method for calibrating zero positions of a continuous casting-and-rolling high-speed flying shear rotating drum and equipment. A first rotating drum, a second rotating drum, a first horizontal plane, a second horizontal plane and a calibration block are included, the rotating drum is provided with the first zero position; the second rotating drum is arranged opposite to the first rotating drum, is located below the first rotating drum and is provided with the second zero position, and the first zero position and the second zero position are located on the same straight line; the first horizontal plane is arranged at the bottom of the first rotating drum, the second horizontal plane is arranged at the top of the second rotating drum, and a gap is arranged between the first horizontal plane and the second horizontal plane. When the device is in a shearing state, the gap is a zero gap, and the calibration block is arranged in the gap between he first horizontal plane and the second horizontal plane. The technical problem that the actual coincidence degree of a shearing blade is reduced and can not meet the shearing condition due to the error of theoffline zero position calibration of the rotating drums and the change of the zero position angle is solved. The technical effect of eliminating the error of the offline zero position calibration ofthe rotating drums, improving the accuracy of the zero position, ensuring the shearing conditions, ensuring production and improving the efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of zero-position calibration of a high-speed flying shear drum in a continuous casting and rolling line, in particular to a device and method for zero-position calibration of a high-speed flying shear drum in continuous casting and rolling and equipment thereof. Background technique [0002] The high-speed flying shear of the MCCR continuous casting and rolling line of the iron and steel company is the key equipment in the full endless rolling production mode, because the shearing action is jointly controlled by two independent movements of the high-speed flying of the drum and the variable speed rotation of the eccentric sleeve of the drum. A movement cycle of the eccentric sleeve of the drum includes motions such as static-acceleration-constant speed-acceleration-deceleration-static, etc., and the condition to ensure the smooth cutting of the strip is to ensure that the rotating The drum and drum eccentric...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a continuous casting and rolling high-speed flying shear drum zero calibration device and method and its equipment, which are used to solve the errors in the prior art due to the offline zero calibration of the drum, and the offline, turning, and turning of the drum. Due to the change of zero position angle during the reassembly process, the actual coincidence degree of the shear blades is reduced and the shearing conditions are not met, resulting in major accidents such as continuous cutting of strip steel, stacking of steel, and lying billets of the casting machine.
