Embodiment Construction

[0029] An embodiment of the present invention provides a control method for looper deviation at the entrance of a galvanizing production line to solve the technical problem in the prior art that the deviation of the looper is likely to occur at the entrance of the galvanizing production line.

[0030] In order to solve the technical problems in the above-mentioned prior art, the general idea of ​​the technical solution provided by the embodiment of the present application is as follows:

[0031] The amount of loopers at the entrance of the galvanizing production line is controlled below 80% of the full amount, and the filling speed is controlled according to the preset welding speed, the remaining length on the strip uncoiler and the amount of loopers.

[0032] In the above method, by controlling the amount of loops at the entrance of the galvanizing production line to less than 80% of the full set; the scraping of the strip steel in the loops can be reduced, thereby preventing...

Abstract

The invention discloses a control method of deviation of a looper of a galvanization production line entrance. The method comprises the following steps: controlling loop height of the looper of the galvanization production line entrance to be 80% or lower of full loop height and controlling looper filling speed according to preset welding speed, residual length of a strip steel uncoiler and the loop height of the looper. The method solves the technical problem that the deviation of the looper is easily generated at the galvanization production line entrance in the prior art.

Description

technical field [0001] The invention relates to the technical field of galvanized product production, in particular to a method for controlling deviation of an inlet looper of a galvanized production line. Background technique [0002] With the development of the domestic iron and steel industry market, product structure adjustment, specification development and expansion, and quality and quality upgrading have become the main research directions of iron and steel enterprises. Among the galvanized products produced by the hot-dip galvanizing unit, the ultra-thin galvanized products with a thickness of less than 0.35mm are mainly used in the back panels, side panels and panels of white goods such as washing machines, refrigerators, and air conditioners, and have relatively high requirements on the surface quality of the products. . As home appliance manufacturers face low processing costs and high surface quality requirements, the market demand for this specification of home...
