Collection and fixation of oil vapor emitted by the coils after cold rolling of stainless steel strips

The cold rolling operation is carried out with a large overflow of oil lubr icant. The rolled strip heats up to around 100 degrees C in relation to the cold reduction Same of the lubricant is vaporized; this part is captured b y mill hoods, but a certain amount of lubricant remains at the surface of t he strip after coiling and is vaporized slowly during storage Although thes e vapors have no toxicity the acceptable level is below 5 mg/Nm(3) and a co llecting system is suitable. The air has to be treated before recycling in the atmosphere. The working conditions with lip to date Sendzimir milts (ro lling speed around 1000 m/min) showed that the collection and treatment by zeolite is the most suitable solution.The cold rolling operation is carried out with a large overflow of oil lubricant.
