Problems solved by technology
The existing cleaning sections are all cleaned through the setting and adjustment of system parameters, but there is no complete set of equipment adjustment processes and methods before parameter setting, resulting in large cleaning effects of the same parameters in different cleaning sections and at different times difference, resulting in poor cleaning effect and serious equipment damage

Embodiment Construction
[0018] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0019] The invention provides a hot-dip galvanizing cleaning section adjustment method, comprising the following steps,
[0020] Step 1: Determine the height of the turning rollers in the alkali section and water section of the cleaning section
[0021] To determine whether the height of the rolling line in the cleaning section is correct, first determine whether the height of the two steering rollers is correct. Determine the height of the two steering rollers according to the calibrated position when the steering rollers are installed. At the same height, the deviation is less than 2mm;
[0022] Step 2: Determine the Le...

Abstract
The invention belongs to the technical field of production for steel products, and specifically provides an adjustment method for a cleaning section of hot-dip galvanizing. The adjustment method for the cleaning section of hot-dip galvanizing comprises the following steps: step 1, determining the heights of turning rolls in an alkali section and a water section of the cleaning section; step 2, determining the levels of the turning rolls in the two sections; step 3, adjusting the level of a support roll; step 4, adding a horizontal line; step 5, adjusting the height of the support roll; and step 6, adjusting and calibrating the position of a brush roll. According to the adjustment method for the cleaning section of hot-dip galvanizing, through an adjustment process for the equipment parameters of the cleaning section, good matching between the equipment of the cleaning section and production process parameters is realized; and the cleaning section adjusted through the method is capableof ensuring the quality of cleaned strip steel, and prolonging the service lives of the related equipment.
Description
technical field [0001] The invention belongs to the technical field of steel product production, and specifically provides a hot-dip galvanizing cleaning section adjustment method. Background technique [0002] The cleaning effect of the galvanizing unit directly affects the quality of the later products, so the guarantee of the cleaning effect in the cleaning section is one of the key control indicators for galvanized products. The cleaning section of the hot-dip galvanizing line is generally divided into alkali immersion, alkali scrubbing, electrolytic cleaning, water scrubbing, rinsing, squeezing and drying, etc. The strip steel is cleaned by saponification reaction and mechanical cleaning of part of the residual oil and iron on the surface of the strip steel by alkaline leaching and alkaline scrubbing. The electrolytic cleaning is to clean the strip steel by electrolyzing water raw materials, followed by water brushing and rinsing. Clean the remaining lye and residues o...
