1. Automobile industry The main uses of hot-rolled pickling in the automobile industry are as follows: automobile chassis systems, including frames, sub-frames, etc. Wheels, including rims, wheel radials, etc. Cabin panel. Cabin panels are mainly the cabin floors of various trucks. Other stamped parts include anti-collision bumpers, brake casings and other small internal automotive parts.
2. The machinery industry (excluding automobiles) mainly includes textile machinery, mining machinery, fans and some general machinery.
3. Light industrial home appliances, mainly used to manufacture compressor casings, brackets, water heater liner, etc. Chemical oil barrel.
4. Other bicycle parts, various welded pipes, electrical cabinets, highway guardrails, supermarket shelves, warehouse shelves, fences, iron ladders and stamping parts of various shapes.
The main processes of hot-rolled pickled plates include laser welding, stretch straightening, turbulent pickling, online smoothing, trimming, online oiling, etc.
Pickling specifications are generally 1.5-6.1*800-1650mm. Products include low, medium and high strength stamping steel, automotive structural steel, etc., which are mainly delivered in the form of steel coils. Features of the process: Use hydrochloric acid to clean the rusty iron sheet on the hot-rolled steel plate to obtain a beautiful and smooth surface.
