Production switching production channel and switching method for two different steel plate products

Abstract

The invention discloses a production switching production channel for two different steel plate products. The production switching production channel comprises a continuous annealing furnace, a galvanizing process section, a continuous annealing aging process section, a zinc pot and a switching channel device, and a switching space for placing the zinc pot and the switching channel device is arranged among the continuous annealing furnace, the galvanizing process section and the continuous annealing aging process section; a steel plate of the continuous annealing furnace is installed in the zinc pot and conveyed to a sink roller of the galvanizing process section, the front end of the continuous annealing aging process section is connected with a conversion channel, the conversion channeldevice is provided with an inlet flange connected with a furnace nose of the continuous annealing furnace and an outlet flange connected with the conversion channel, and a steering roller for conveying the steel plate of the continuous annealing furnace to the continuous annealing aging process section is further mounted on the channel switching device. The design is scientific and compact in structure, small in occupied space, convenient to disassemble and assemble and flexible in hoisting. The invention further discloses a steel plate production process switching method achieved through theswitching production channel.

Description

technical field [0001] The invention relates to the technical field of steel plate production equipment maintenance, in particular to a production channel structure and switching method for production switching of two different steel plate products. Background technique [0002] For the existing continuous annealing line, the actual production load has been at a low level for a long time, and the equipment has been shut down for a long time, causing serious waste. However, the market demand for hot-dip galvanized products is very large. At the same time, the equipment and processes before and after the continuous annealing line and the galvanizing line The process is basically the same. To transform the existing continuous annealing unit into a dual-purpose production line that can produce both ordinary cold-rolled products and galvanized products, it is necessary to switch to a different process production line to realize the production of two different products.
