Problems solved by technology

However, the process in the prior art has the following problems: 1) This process has an additional logistics process of galvanized sheet, which increases the logistics cost and loss; 2) In the prior art, additional embossing production equipment needs to be invested, which increases equipment investment and cost. Site requirements; 3) The production efficiency of this process is reduced, which is equivalent to the embossing operation after the galvanizing process is completed. The entire process is complicated and increases labor costs

Embodiment 1

[0017] Example 1 : A continuous galvanized flat embossing process, the process consists of the following steps, 1) uncoiling, 2) welding, 3) degreasing, 4) drying, 5) annealing, 6) continuous galvanizing, 7) galvanizing After cooling, 8) flattening and embossing, 9) stretching and straightening, 10) surface treatment, 11) curling, 12) coiling; the step 3) degreasing process is as follows. Stage: the first stage, spray alkali washing and squeeze dry, the second stage, brush and squeeze dry at the same time of spraying, the third stage, use clean water for secondary cleaning and squeeze dry, the fourth stage, dry the wet strip surface deal with. It can remove impurities such as oil stains and iron filings on the surface of cold-rolled strip steel, so that the strip steel has a clean surface before entering the furnace, which is very important for the production of galvanized products with high surface quality and high coating bonding force; the step 5 ), the annealing temperat...

Abstract

The invention relates to a continuous galvanizing flat knurling process. The process includes the following steps of (1) uncoiling, (2) welding, (3) degreasing, (4) drying, (5) annealing, (6) continuous galvanization, (7) cooling conducted after galvanization, (8) flat knurling, (9) withdrawal and straightening, (10) surface treatment, (11) coiling and (12) divided winding. Compared with the prior art, the process has the following advantages that the whole process is simple, operation is easy, additional investment of capital for additional arrangement of a knurling production device is not needed for the process, and a continuous galvanizing knurling process can be finished simply by properly adjusting an existing production line; the production efficiency of the whole process is high and a continuous galvanizing process and a flat knurling process are finished on the same production line at the same time; the field use requirements of the process are lowered and labor cost is reduced; the logistic process of a galvanized sheet is omitted through the process and logistic cost and loss are reduced; a continuous galvanized knurled sheet produced through the process is good in quality and is widely accepted by customers.

Description

technical field [0001] The invention relates to an embossing process, in particular to a continuous galvanizing smooth embossing process, which belongs to the technical field of continuous galvanizing. Background technique [0002] Continuous galvanizing refers to the surface treatment technology that coats a layer of zinc on the surface of metal, alloy or other materials to play the role of aesthetics and anti-rust. Zinc, but also hope that there are good-looking patterns on the surface of the metal, so that the appearance of the product is more beautiful. The embossed galvanized sheet in the prior art is processed and produced by an independent embossed production line, and its raw material is galvanized sheet. After the embossing production line is processed, it is made into an embossed galvanized sheet. However, the process in the prior art has the following problems: 1) This process has an additional logistics process of galvanized sheet, which increases the logistics ...
