  • ID del Producto: 01_1

     Hot rolled steel sheet after acid tank when a certain concentration and temperature of hydrochloric acid, hydrochloric acid and iron oxide steel sheet surface a series of chemical reactions, iron oxide skin to dissolve, ultimately no rust, smooth plate.
product description:
     The main step of laser welding hot pickling, tensile straightening, turbulence pickling line leveling, trimming, coating oil online.
product features:
(1) reduce costs, instead of cold-rolled plate pickling plate, cost savings for the enterprise.Good

(2) surface quality, compared with ordinary hot-rolled plate, hot-rolled pickled plate removes surface scale, improve the surface quality of steel, easy welding, oiled and painted.
(3) high dimensional accuracy, after formation, the occurrence of certain changes can plate, thereby reducing the unevenness deviation.
(4) improve the surface finish and enhanced appearance.

(1) Automotive industry: hot pickling in the automotive industry, mainly for the following: automotive chassis systems, including girders, beams and other vice. Wheels, including rims, wheels radiation. Cab board.
      Carriage plate, the main compartment floor is a variety of trucks. Other stampings, including collision bumper, brake between brake sets and some other small parts inside the car.
(2) :( machinery industry excluding motor vehicles) including textile machinery, mining machinery, general machinery as well as some fan.
(3) Light appliances: home appliances, mainly for the manufacture of the compressor casing, frame, water heater and so on. Chemical drums.
(4) Other: bicycle parts, all kinds of pipe, electrical cabinets, highway guardrail, supermarket shelves, storage shelves, fence, iron ladder and stamping parts of various shapes.
