The company descales steel billets by shot-blasting. The shot-blasting consists of propelling metallic grit against the billet to be treated, to ensure the shattering of the calamine layer. This operation takes place in an armored chamber. The dust is vacuumed to a de-dust accumulator room before discharge, The grit mixed with calamine is recycled. The standard technique is totally different since the descaling is brought about by the action of the acid as the billets are dipped in successive baths.
