Embodiment

[0031] Please refer to figure 1 , figure 1 Shown is the schematic diagram of the steel coil pickling and leveling unit 100. The steel coil pickling and leveling unit 100 can be mainly used for pretreatment of raw material steel coils, and the pretreated steel coils can be used as raw materials for subsequent cold rolling and galvanizing or can also be used directly. In this embodiment, the treatment of the steel coil and the galvanizing of the steel coil are used as an example for subsequent description. Of course, in other embodiments, the steel plate can also be processed, and the surface of the steel plate can also be plated with other materials, such as aluminum.

[0032] This embodiment provides a steel coil pickling and leveling unit 100, which includes a cleaning section 110, a leveling section 150, and a post-processing section 170 connected in sequence. The cleaning section 110 is mainly used to clean the raw steel material to remove surface debris such as iron oxide sc...

Abstract

The invention provides a steel coil pickling leveling unit and a steel coil production method, and relates to the technical field of steel processing. The steel coil pickling leveling unit comprises acleaning section and a leveling section which are connected with each other. The leveling section comprises a first leveling machine, and the first leveling machine comprises a knurling roller. The first leveling machine is arranged on the steel coil pickling leveling unit on line, and a separate first leveling unit does not need to be matched, so that the equipment investment and the personnel cost are reduced, the material circulation loss is reduced, and the total flow total yield is improved. Meanwhile, the thickness dimension precision error of a hot-rolled substrate can be effectively eliminated through leveling treatment, the precision requirement of a cold-rolled plate is met, and more precise use requirements of products can be met. In the process of leveling the steel, knurlingon the surface of the steel is also realized. After steel is flattened and embossed, the shape of the steel is improved, the adhesive force of zinc liquid is increased through knurling on the steel surface, a zinc layer is more stable, the thickness of the zinc layer is more uniform, and the market competitiveness of a steel plate is greatly improved.

Description

Technical field [0001] The invention relates to the technical field of steel processing, in particular to a steel coil pickling and leveling unit and a steel coil production method. Background technique [0002] With the development of China's industry, the proportion of galvanized steel coil demand is rapidly increasing. Before steel coil raw materials become finished steel coils, they often need to undergo a multi-step pretreatment process to provide qualified raw materials for subsequent cold rolling, galvanizing or direct use. At present, the pretreatment process of steel coils is still not perfect, making finished steel coils still unable to meet the requirements of many users. Summary of the invention [0003] The purpose of the present invention is to provide a steel coil pickling and leveling unit, which can further improve the pretreatment of the steel coil so that the steel coil can meet more requirements of users in the later processing. [0004] Another object of the p...
