[0002] High-strength steel usually contains more alloying elements, such as carbon, manganese, silicon, chromium, etc. These elements may have complex chemical reactions with acid during pickling, generating some compounds insoluble in acid, such as silicates, chromates, etc. These substances are easy to deposit in the pipeline of the heater, causing blockage. In order to improve the efficiency of pickling, the heater usually needs to heat the acid to a high temperature.
