PURPOSE:To prolong the life of a sliding plate by using it in combination with a fresh stationary plate at the half of the service life of the stationary plate and the sliding plate and exchanging the stationary plate while the sliding plate has still remaining life. CONSTITUTION:A new C stationary plate 3 and a newIsliding plate 5 are set in combination, and after (a) nozzles 6, 10 are used 3-5 times, the plates are disassembled, and the plate 3 is held free and is allowed to cool. A new D stationary plate 3 and the plate 5 under use are set in combination and are used until the damages of the plate 5 attain the limit of its life by the nozzles 6, 10. When the plate 5 is used to the limit, the plates are disassembled and the plate 5 is discarded; at the same time, the plate 3 is allowed to cool. The cooled plate 3 and a new II sliding plate 5 are set, and after the plate 3 is used 3-5 times by using (b) nozzles 7, 11, the plates are disassembled, and a new E stationary plate 3 and the plate 5 under use are set, and the nozzles 6, 10 are used.
