Energy-saving cold-rolled steel coiled plate alkali liquor cleaning and degreasing equipment and using method thereof

Abstract

The invention discloses energy-saving cold-rolled steel coiled plate alkali liquor cleaning and degreasing equipment and a using method thereof, and relates to the technical field of cold-rolled steelcoiled plate processing. The equipment comprises a liquid collecting box for collecting an alkali liquor. A top surface of the liquid collecting box is an opening structure and is fixedly connected with a table plate. A mounting box is fixedly connected to an upper surface of the table plate, symmetrically-arranged partition plates are fixedly connected to two sides of an internal portion of themounting box, the internal portion of the mounting box is divided into a drying chamber, a cleaning chamber and an empty chamber from left to right through the partition plates, and meanwhile throughgrooves allowing a cold-rolled steel coiled plate to penetrate through are arranged in the partition plates and the two sides of the liquid collecting box. The alkali liquor sprayed out of the cleaning chamber can achieve a cleaning and degreasing process of the cold-rolled steel coiled plate so as to ensure plate quality before galvanizing. And then the cold-rolled steel coiled plate enters intothe drying chamber to be rapidly air-dried, the surface of the cold-rolled steel coiled plate is blown to be clean, liquid stains on the surface of the cold-rolled steel coiled plate are subjected tohot drying, a bright effect of the plate surface is guaranteed, and a previous guarantee is provided for a next step of machining.

Description

Technical field [0001] The invention relates to the technical field of cold-rolled steel coil processing, in particular to an energy-saving cold-rolled steel coil lye cleaning and degreasing equipment and a use method thereof. Background technique [0002] Cold-rolled steel coils are made of hot-rolled steel coils, which are pickled to remove oxide scale and then cold-rolled. The finished products are hard-rolled coils. With the development of the market economy, users of cold-rolled steel coils are not only concerned about the size of the product Accuracy and performance are concerned, and the cleanliness of the surface of cold-rolled steel coils is increasing. At present, the raw material steel plate of cold-rolled steel coil must be degreasing treatment before hot-dip galvanizing. Generally, lye is used for cleaning and degreasing. [0003] The existing lye cleaning and degreasing do not have a drying process for the steel coil after cleaning and degreasing, resulting in liquid...

AI Technical Summary

Problems solved by technology

[0003] The existing lye cleaning and degreasing does not have a drying process for the steel coil after cleaning and degreasing, resulting in residual liquid stains affecting the rapid use in the next step, and the contact between the lye and the two sides of the steel coil is not sufficient, which is easy to cause cleaning The problem of dead angle will affect the cleaning effect. At the same time, the impact force between the lye and the steel coil surface is small, and some attached stains cannot be washed away, which will affect the subsequent processing process.
