Embodiment

[0023] The raw material hot-rolled strip is processed by pre-rolling processes such as pickling, and then cold-rolled. The cold tandem rolling unit 1 is a five-stand cold tandem rolling unit, the strip width is 1250 mm, and the thickness of the finished product is 0.8 mm. mm, the rolling speed is 30m / s; after the strip is rolled to the required size, it enters the cleaning unit 2 for cleaning treatment to remove the remaining rolling oil and other surface stains on the surface of the cold-rolled strip, and the electrolytic cleaning tank adds 2% Alkaline degreasing agent, the electrolytic current is 2000A, and then the strip enters the inlet looper 3, and adapts to the change of rolling speed and annealing speed by adjusting the amount of the inlet looper; after the strip steel inlet and outlet looper 3 enters the continuous annealing unit 4, the The heat treatment of the step is divided into six stages, which are preheating section, heating section, soaking section, primary coo...

Abstract

A short-process production method for cold-rolled steel plate punching mesh, which mainly includes: after the raw material hot-rolled steel strip is pickled and pre-rolled, it is cold-rolled and continuously annealed, and then enters the stamping process for punching, cleaning and After surface treatment, cut to length, and finally get punched mesh or punched mesh roll. The equipment for the above-mentioned short-process production method of cold-rolled steel plate perforated mesh mainly includes cold continuous rolling unit, cleaning unit, inlet looper, continuous annealing unit, outlet looper, leveling unit, punching machine, straightening machine, cleaning equipment, surface treatment Equipment, shears, coilers or finished pallets. The invention combines the continuous cold rolling and continuous annealing process of the cold-rolled steel plate with the stamping and surface treatment process, so that the rolling deformation, heat treatment and deep processing process of the punching net of the cold-rolled steel plate are recombined, and the production process is shortened compared with the traditional production process. The process reduces the logistics and transportation, reduces the production cost, increases the product price per unit weight, and increases the economic benefits of the steel plant.

Description

technical field [0001] The invention relates to the technical field of metallurgical processing, in particular to a method and equipment for producing punching nets for cold-rolled steel plates. Background technique [0002] In recent years, the demand for cold-rolled steel punching mesh is increasing day by day, and the application fields are becoming wider and wider. It can be used for the ceiling of buildings, exquisite decorative orifice plates for environmental protection tables and chairs, protective covers for mechanical equipment, shelf nets for shopping malls, ventilation nets for grain depots, etc. In the existing production process, the punching process of the cold-rolled steel plate punching mesh and the production of the incoming cold-rolled sheet are carried out separately, that is, the incoming sheet is first rolled and annealed in the steel mill, and then the wire mesh factory Purchase cold-rolled plates (coils) from steel mills, transport them to the stampi...
