A continuous casting and rolling high-speed flying shear drum zero calibration device and method and its equipment

Abstract

The invention discloses a continuous casting and rolling high-speed flying shear drum zero calibration device and method and its equipment, comprising: a first drum, a second drum, a first horizontal plane, a second horizontal plane, a calibration block, a first The drum has a first zero position; the second drum is arranged opposite to the first drum, located below the first drum, and has a second zero position, and the first and second zero positions are on the same straight line; The first horizontal plane is set at the bottom of the first drum, and the second horizontal plane is set at the top of the second drum. There is a gap between the first and second horizontal planes. When the device is in the shearing state, the gap is zero gap; calibration block Disposed in the gap between the first and second horizontal planes. It solves the technical problem that the actual coincidence degree of the shearing blades decreases due to the error of the offline zero position calibration of the drum and the change of the zero position angle, which does not meet the shearing conditions. It achieves the technical effect of eliminating the error of the offline zero calibration of the drum, improving the precision of the zero position, ensuring the cutting conditions and improving the production efficiency.

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.
