Problems solved by technology

The defect of this production process is that: reheating the high-temperature slab after cooling will easily cause a lot of energy consumption, even if it is hot charging and hot delivery, it still needs to be heated, which also consumes a lot of energy; the construction investment of the rolling heating furnace, daily maintenance , material consumption, etc. will also consume huge economic input
Although the patent cancels the heating furnace, the device uses multiple rows of continuous casting slabs in parallel. After the steel is divided by the horizontal allocation device, a single piece is sent to the hot delivery roller table, which will cause the continuous casting slabs entering the hot delivery roller table to wait. The cooling time of the continuous casting slab is also increased due to the need to move the steel horizontally
Essentially, this device is not fundamentally different from the current hot-feeding and hot-charging technology, and the temperature drop of the continuous casting slab is too large to meet the rolling requirements of the rolling mill.

Abstract

The invention provides a high-speed direct-delivery direct-rolling system and method for wire bar continuously-cast slabs. The system comprises a small-radius high-drawing-speed continuous casting machine, a fast hydraulic shear, a cut slab roller table, a slab discharging roller table, a grouped cast slab hot-delivery roller table, a single-cast-slab delivery roller table and a wire bar rolling mill which are sequentially and compactly arranged. A transverse steel transfer machine is arranged between the slab discharging roller table and the grouped cast slab hot-delivery roller table. A steel bar splitting machine is arranged between the grouped cast slab hot-delivery roller table and the single-cast-slab delivery roller table. Cast slabs are gathered into groups on the slab discharging roller table and transferred into the grouped cast slab hot-delivery roller table from the transverse steel transfer machine. The grouped cast slabs are split into single cast slabs through the steel bar splitting machine and delivered to the wire bar rolling mill through the single-cast-slab delivery roller table for rolling. The small-radius high-drawing-speed continuous casting machine is efficient in continuous casting, the drawing-out temperature of the cast slabs is high, the shape of the cast slabs is regular, and the temperature loss is small; and the cutoff speed of the cast slabs is high, and the initial temperature of the cast slabs is high. All streams of the cast slabs are grouped at a high speed through the transverse steel transfer machine and delivered in a grouped manner through the hot-delivery roller table for steel rolling, and by means of the manner, the temperature drop is extremely small in the delivery process of the cast slabs.

Description

technical field [0001] The invention belongs to the technical field of metal continuous casting and rolling, and in particular relates to a high-speed direct-feeding and direct-rolling system and method for continuous casting slabs of wire and rod. Background technique [0002] At present, the production process of wire and bar is mostly: the molten steel is cooled and solidified by the continuous casting crystallizer and the secondary cooling section, and then straightened by the drawing and leveling machine to pull out the cast slab, and the cast slab is cut to length by flame and then conveyed by the cutting roller table and The roller table is sent to the blanking area. The casting slabs that need to be hot-sent are sent to the hot-sending roller table through the steel turning machine, steel transfer machine, and steel separator, and are directly sent to the rolling steel into the heating furnace; Send it to the steel turning cooling bed for cooling, and then the slab ...
