摘要： METHOD OF OPERATING A REHEATING FURNACE IN A HOT ROLLING LINE AND A REHEATING FURNACE EMPLOYED THEREFOR A heating method of operating a furnace in a hot rolling line and a heating furnace therefor in which the reheating furnace is positioned between a continuous casting apparatus and a rolling apparatus for rolling workpieces selectively at a speed higher than they are cast or at a speed equal to the speed at which they are cast by the casting process, the furnace serving as a heating and buffer zone. The reheating furnace includes at least three moving beams each having an independent driving mechanism, and coupling mechanisms which couple the neighboring moving beams for independent or synchronous movement, while the moving beams are so arranged that, by operating the driving mechanism, they are altered in their speeds to the discharging speed of the workpieces from the continuous casting process, or one or two of the moving beams are brought into idling state or driven at the rolling speed.

摘要： A base plate coating method using a die coater. A base plate is placed on a support surface having a flatness of not more than 2 mu m and a plurality of suction holes. The base plate is then sucked onto the support surface via the suction holes and thereby brought into close contact therewith. Consequently, the deformation (for example, torsion and flexure) of the base plate is eliminated. A coating liquid discharged vertically from a die coater is then applied to the base plate as the die coater is moved relatively to the base plate. As a result, a film of coating having a predetermined thickness is formed on the base plate.
