The technology of hydrochloric acid pickling is applied all over the world and it replaced the technology of sulphuric acid pickling long ago, at the same time the hydrochloric acid recovery technology has been developed. Acid recovery production on the one hand decreases the acid consumption specific yield, on the other hand it can obtain by-product of Ferric oxide. Ferric oxide with silicon is used for iron ore, and desiliconized ferric oxide is used for magnetic tape and soft magnetic material for computer. ARL can make a good profit.

Spray Roasting ARL is a process of Fecl2 reacted

with H2O at high temperature, forming HCL and Fe2O3. A desilication device can be applied to increase the purity of the Fe2O3. The process can recycle more than 90% of HCL and decrease consumption of new HCL in pickling line to 1 kg per ton steel, moreover it can improve the quality of pickling. The technology is applied for many plants over the world.

During the galvanizing entry section or high temperature annealing, the oil or grease on the surface of the strip will affect the galvanized surface quality and conglutination of the strip. Degreasing & rinsing line is applied for removing oil, residual iron and other contamination on the strip, so as to control the value of the residual carbon and iron surface quality and cleanliness can be guaranteed, especially for the strip for automobile and household electric appliance. We can provide the following degrease line.

Electro-degreasing & Rinsing Line

When the strip runs through alkali liquid tank, and the strip is set as anode or cathode through DC with reversal polarity, then gas is created on surface of the strip, which emulsifies the oil film and separate the oil from the strip surface It is provide by productivity practice that the processing of electrolytic degrease is better than alkali degrease in many sides, such as degreasing efficiency and quality.
