Electrolytic tinning Line

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.
