Description

TECHNICAL FIELD

[0001] The present application relates to steel processing equipment, in particular to a roughing billet shearing device and a shearing length control method. BACKGROUND

[0002] Roughing is to roll the ingot or continuous casting bloom into the required size of the raw material billet for the next process product rolling mill, which creates conditions for multi-variety steel production, has the advantages of flexible specification change, easy small batch production and uniform rolling organization structure. In the roughing production, the ingot or continuous casting bloom is heated and then enters the roughing mill for rolling. Before entering the next process, it needs to be cut and segmented. The length of the segmented bloom needs to meet the contract and production process requirements. Generally, the length range has an interval. If the length after segmentation is within the interval, it is qualified, otherwise it can only be regarded as waste.

[0003] Patent document CN204584393U discloses a billet shearing machine, which comprises a machine head and a shearing platform. The lower end face of the machine head is fixedly provided with a sliding rail. The sliding rail is fixedly connected with a liftable tool holder. A lifting device for providing lifting power for the tool holder is fixedly arranged on the upper end face of the machine head. The tool holder is provided with an upper shearing cutter. The number of the upper shearing cutters is at least two. The shearing machine body is further provided with a billet input port. The upper end face of the shearing platform is fixedly provided with a backing plate. The backing plate is located in front of the billet input port. The backing plate is provided with a lower shearing cutter at the end close to the billet input port and the end away from the billet input port. The lower shearing cutter is detachably connected with the shearing platform. The position of the lower shearing cutter corresponds to that of the upper shearing cutter. The billet shearing machine is provided with position-adjustable upper and lower shearing cutters, so that the billet shearing machine has a measuring and shearing function and improves the shearing precision.

[0004] However, during the shearing operation of this shearing machine, the full length of the bloom is first estimated according to the weight and cross-sectional size of the current bloom. Then, the length of each segment is calculated according to the current contract segment length requirement and experience. Then, the segment shearing operation is performed by referring to the reference scale. This has many problems such as large error in the full length of the bloom, low efficiency in manual calculation of the segment length, large error in the length of the segmented bloom, etc. It is easy to cause the size of the bloom to not meet the process requirements when it is sheared and segmented to the last segment, so it can only be regarded as waste, resulting in a high cutting loss rate of the bloom.
