A kind of production method of continuous hot-dip galvanized embossed sheet

Abstract

The invention discloses a production method of continuous hot-dip galvanized on-line embossed board, which comprises the following steps: Step 1, alkali washing and degreasing; Step 2, annealing and reduction; Step 3, surface galvanizing; Step 4, surface embossing; Five, the surface is environmentally friendly and anti-fingerprint coating. The invention also relates to a four-roll skin pass machine, which includes a machine body, an embossing mechanism, a guiding mechanism and an anti-shaking mechanism. The galvanized sheet embossing and finishing machine involved in the present invention can effectively carry out online embossing on the galvanized sheet, and can effectively synchronize with the speed of the hot-dip galvanizing production line, increase the production capacity, and reduce the cost of midway transportation and the occurrence of non-transportation during the process. It can effectively reduce the vibration of the board during the embossing process, ensure the consistency of the pattern on the board surface, and improve the aesthetics of the board.

Description

technical field [0001] The invention relates to the field of galvanized embossed sheets, in particular to a production method for continuous hot-dip galvanized on-line embossed sheets. Background technique [0002] In the existing embossed sheet production methods, most of the sheets are galvanized in the early stage and then embossed outside the line, which easily increases the production cost, and the production line speed and production capacity are restricted. At the same time, the existing sheet galvanizing method is cumbersome, and The surface adhesion of the galvanized plate is poor, and it cannot be well bonded to the protective layer. The surface protective film is prone to damage and peeling off, which can easily reduce durability, resulting in shelling, peeling, and rusting of the plate. Contents of the invention [0003] 1. Technical problems to be solved [0004] The patterned plate embossing and finishing machine involved in the present invention can effecti...
