摘要： The present invention relates to a method of producing a fluxing agent that can be used in production of steel, preferably stainless steel, characterised in that as a raw material for the production of said fluxing agent is used a hydroxide sludge resulting from neutralisation of metal-contaminated pickling liquid from a pickling step for a steel, said hydroxide sludge containing at least one fluoride-containing compound, and that said hydroxide sludge is calcined. The invention also relates to a method in connection with steel production, preferably stainless steel, comprising production of a steel heat and decarburization of the steel heat, whereby a slag is formed on top of said steel heat, characterised in that a product according to the invention is added to said slag. The invention also relates to the product produced according to the invention.

摘要： A method for heat-treating steel, primarily strip-like or rod-like steel material, such as steel strip, steel sheet, steel rod or steel wire which have been rolled and heated in an oven or furnace to a surface temperature above about 900 DEG C and thereafter cooled and optionally treated in an electrolyte bath and/or acid bath. The invention is characterized in that the oven burners are fired with a liquid or a gaseous fuel which is burned with the aid of a gas that contains at least 85 % by volume oxygen and at most 10 % by volume nitrogen.
