The cold rolling of steel is to start from Germany in the middle of the 19th century, can only produce the cold-rolled strip that width is 20-25mm at that time. The U.S. establishes 25mm cold-rolling mill in 1859, within 1887, produces the mild-carbon steel strip that width is 150mm. Cold-rolled strip produces and develops quickly in Germany, the U.S. after 1880, and product width constantly expands, and progressively establishes auxiliary device, and as sheared, aligning, smooth and Equipment for Heating Processing etc., product quality there has also been raising.
Pickling is an important link in cold-rolled strip production process, and pickling is the process of oxidation on metal surface iron sheet of chemically going out, and generally adopts hydrochloric acid, is therefore also chemical pickling. In the production process of steel band, acid cleaning process control is improper at present is easily caused steel band defect, and as deficient pickling causes ribbon stripe speckle, overpickling causes that surface is dark-coloured, and parking speckle surface is in yellow black speck, while split, and wrinkle, wipe scuffing, foreign body is pressed into, pore, iron scale press-in etc. The impact by many factors of the surface iron scale of hot rolled strip and the chemical reaction velocity of acid solution, such as concentration and temperature, the surface of steel plate temperature etc. of acid solution, it is impossible to unconfined raising. But then, in practical scope, surface of steel plate temperature is made to be rapidly reached the temperature of acid solution, thus must accelerating the material transmission of surface of steel plate, namely the diffusion of acid and chemical reactant, improves conductivity, its method makes acid solution form High Speed Turbulent at belt steel surface exactly, promoting material transmission, reaching the purpose making surface of steel plate heat up rapidly, thus being greatly shortened pickling time.
It is good all not that the pickler that presently, there are is made in producing High Speed Turbulent, causes that pickling effect is general. Meanwhile, acid cleaning process unavoidably produces acid mist, it is easy to spill in environment, environment is caused a degree of pollution.
