摘要： Method for the continuous manufacture of steel strip in which steel strip is fed into an annealing furnace at a certain feed-in rate and drawn out of the furnace at a rate higher than the feed-in rate while subjecting the steel strip to a pulling force in the annealing furnace at a temperature above the recrystallization temperature of the steel in the region of 1000.degree. to 1250.degree. C. This results in the introduction of a permanent stretch of the steel strip corresponding to the difference between the feed-out and feed-in rates as well as a reduction in the cross-section of the strip corresponding to the elongation and a reduction of the strip thickness and strip width.

摘要： A method and apparatus for heating a sheet-like material to a predetermined temperature profile along the length and across the width of the material. The sheet-like material is transported within a furnace relative to at least one burner holder above or below, or above and below, the material. Each burner holder includes a number of direct flame impingement burners located side-by-side in a row. The burners are directed toward the sheet-like material, and the individual burners in each burner holder are oriented and controlled so that heat output from the burners provides the predetermined temperature profile within the sheet-like material.

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 degrees C. and thereafter cooled and optionally treated in an electrolyte bath and/or acid bath. 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 percent by volume oxygen and at most 10 percent by volume nitrogen.

摘要： A strip of stainless steel, which is cast and/or hot rolled and which is dark colored by oxides on the surface of the strip, remaining from the foregoing manufacture of said cast and/or hot rolled strips, is cold rolled in one or more cold rolling passes (11-13) following after each other, so that the thickness of the strip is reduced by 10-75% and so that the oxide scales crackle, i.e. so that fissures are established in the oxide layers. Thereafter, the strip is annealed in a furnace (18) having a furnace atmosphere obtainable by heating the furnace by means of burners which consume a liquid or gaseous fuel, which is combusted by means of a gas which contains at least 85 vol-% oxygen and not more than 10 vol-% nitrogen, wherein a furnace atmosphere is created, in which the strip can be annealed without oxidising the metal surfaces which are exposed through the crackling, in a way which would make the subsequent descaling and pickling difficult.

摘要： The invention relates to a method of working a hot-rolled stainless steel strip, particularly an austenitic stainless strip, with the intention of reducing the thickness and enhancing the mechanical strength of the strip. The method is characterized by cold-rolling the hot-rolled strip with at least a 10% thickness reduction to a thickness which is at least 2% and at most 10% greater than the intended final thickness of the finished product; annealing the thus cold-rolled strip at a temperature of between 1,050.degree. C. and 1,250.degree. C.; and cold-stretching the strip after the annealing process so as to plasticize and permanently elongate the strip and therewith reducing its thickness by 2-10%.
