Production facility and method for high-intensity packing steel belt

Abstract

The invention relates to a method for producing high-strength packing steel band. Wherein, the inventive device comprises material preparer, induction heating furnace, end cutter, high-pressure water dephosphorize device, eight thermal rollers, one cold roller, middle cooling section, wide closed controller, thickness closed controller, movable sleeve, coater, and coiler; and the method comprises: preparing materials, induced heating, cutting end, removing phosphor, thermally rolling, controlling width, cooling, cold rolling, coating, coiling, while it can add welder and additive heater. In the production, the temperature of heating furnace should be controlled accurately, and the cooling speed should be controlled. The inventive steel band has high quality while the width accuracy is 0-1mm, and its cost is low.

Description

technical field [0001] The invention belongs to the technical field of packaging steel strips, in particular to production equipment and a production method for high-strength packaging steel strips. Background technique [0002] Due to the excellent mechanical properties of steel belts, many processes and many products in many industries use steel belts for packaging. With the progress of society and the development of technology, the demand for high-strength packaging steel belt is also increasing. [0003] The traditional manufacturing process of high-strength packaging steel strip is: cutting hot-rolled or cold-rolled strip steel into narrow strips-cold-rolling the slit narrow strip-cold-rolled and then slitting (or hot-rolled wide-band steel-cold-rolled After cutting) - heat treatment (to obtain ideal structure and performance) - then paint, wax and other processes to form a finished product. The disadvantage of this manufacturing process is that there are many process...

AI Technical Summary

Problems solved by technology

[0004] 1. The heating speed of ordinary electric heating is slow, so the heating time is prolonged and the length of the heating furnace is longer

[0005] 2. Only two vertical rollers are installed, and the width accuracy is difficult to guarantee

[0006] 3. There is no cold rolling process, and the surface quality and thickness accuracy of the steel strip are poor

[0007] 4. Two sets of straightening machines are installed, so that the equipment cost and production cost are higher. At the same time, the iron sheet on the surface is difficult to remove with the straightening machine, which affects the quality of the steel strip.

[0008] 5. The water mist-air cooling process is not stable enough and the cost is high
