Embodiment Construction

[0008] A continuous casting slab fixed weight shearing device includes a shearing device, a slab roller table 1, a slab flow and a control system. Track beam 12, place mobile trolley 8 on track beam 12, install weighing frame 10 and load cell 9 on mobile trolley 8, be provided with electric push rod 11 on the weighing frame 10, electric push rod 11 links to each other with telescopic rod 7, The end of telescopic link 7 is affixed with shoulder pole beam 5, and hoist 3 and hand joint 6 are equipped with at the two ends of shoulder pole beam 5, and hand joint 6 can grab the billet 2 on the billet roller table 1.

[0009] The control system automatically controls the mobile trolley 8 to be positioned above the slab stream that needs to be weighed according to the requirements, and controls the hand joint 6 to grab the slab 2 to carry out weighing. According to the difference between the weight data obtained by weighing and the target weight, the control system automatically correc...

Abstract

A continuous casting constant-weight cutting device comprises a cutter, a casting roller track, a casting blank flow and a control system. The invention is characterized in that a track beam vertical to the casting blank track is arranged above the casting blank flow of the continuous casting machine, the track beam is arranged with a movable cart disposed with a weight support and a weight sensor, the weight support is disposed with an electric pushing rod connected with a flexible rod whose end is fixed with a beam, two ends of the beam are mounted with a lifter and a hand joint. The invention mounts weight device on the weight cart covering N casting blank flows, therefore, the continuous casting blanks share one weight, to avoid error, and the control system can correct the size via the weight of each flow, to control the weight. The invention can cut the continuous casting blank in constant length and weight, to improve efficiency.

Description

technical field [0001] The invention relates to a constant weight shearing device for continuous casting slabs in the metallurgical industry. Background technique [0002] In the metallurgical industry, the continuous casting slab cross-rolling process has always used "fixed length" as one of the billet supply standards, and most of them use cut-to-length cutting, which only requires the length of the cut billet to be within the specified tolerance range, regardless of its weight. Whether they are equal or not, due to the influence of changes in section size, casting speed, casting temperature, mold taper, etc., the weight of the same specification may not be equal when cut at the same length in different production shifts (such as morning shift and evening shift). This continuous casting slab cut by the same length but with unequal weight will cause great trouble to the improvement of the sizing rate and the yield of the steel rolled in the next process. Contents of the i...
