Equipment and process for manufacturing belt in quenching mode

Abstract

The invention discloses equipment for manufacturing a belt in a quenching mode. The equipment comprises a first hydraulic cylinder, a siphon, a magnetic reeling machine, a cooling roller, a cooling track matched with the cooling roller, a liftable tundish ascending and descending through the hydraulic cylinder, a nozzle package communicated with the liftable tundish through the siphon, a base arranged at the bottom of the nozzle package and a second hydraulic cylinder which is arranged between the nozzle package and the base and can drive the nozzle package to ascend and descend, a cooling channel is formed between the cooling roller and the cooling track, a nozzle of the nozzle package corresponds to an inlet of the cooling channel, the magnetic winding drum of the magnetic reeling machine corresponds to an outlet of the cooling channel, and the length of the cooling channel is larger than one fourth of the perimeter of the cooling roller and smaller than one half of the perimeter of the cooling roller. The nozzle of the nozzle package is arranged above the central line of the cooling roller. A lifting blocking plate capable of controlling the speed of metal liquid flowing out of the nozzle is arranged in the nozzle package. According to the equipment and process, steel belts of different thicknesses can be produced conveniently, the cooling effect is good, and the final performance of materials is easy to control.

Description

technical field [0001] The invention relates to the technical field of material processing and manufacturing, in particular to equipment and technology for rapidly cooling strips. Background technique [0002] At present, conventional quenching strip-making equipment mainly includes horizontal twin-roll strip casting mills, different-diameter twin-roll casting mills, single-roll strip casting mills and strip casting mills. [0003] Specifically, the horizontal twin-roller strip casting mill has the advantages of simple structure, easy control, double-sided crystallization, and good internal quality. However, this kind of casting and rolling mill has poor liquid level stability, poor ability to prevent secondary oxidation, scum being involved affects the quality of strip steel, and there are flashes on the side sealing edge. The side sealing plate of the tundish has strict requirements, is fragile and difficult to replace. In addition, the double-roller type is double-sided ...

AI Technical Summary

Problems solved by technology

The belt casting and rolling machine can realize solidification on one side and cooling on one side (single-belt type), and solidification on both sides and cooling on both sides (double-belt type), but the speed is low and the casting belt is thicker, with a minimum thickness of 8mm, which is not suitable Production trials of thin and very thin strips
