Filed: 1994-08-11
Abstract: PURPOSE:To facilitate the exchanging work of a muffle body, to shorten a time reguired for the exchange work of the muffle body, to prevent the deformation and the deterioration of a flange caused by heat effect and to improve the reliability of sealing atmospheric gas. CONSTITUTION:A metal strip 21 is passed through from a heating furnace 22 to a slow cooling chamber 23 side by up-heat system. The connection between the muffle body 25 and an expansion joint 24 is executed by fastening bolts 33 and nuts 34 together while interposing a gasket 35 between an upper end flange 26 and a lower end flange 27. The gasket 35 is cooled near the inner part side in the peripheral direction with a water-cooling jacket 32 so as not to be deteriorated with the heat for heating the muffle body 25. Since the gasket 35 is used, even if the fastening is executed by using the bolts 33 and the nuts 34, the airtight sealing between the upper end flange 26 and the lower end flange 27 can surely be secured and the heat treatment of the metal strip 21 can stably and continuously be executed.

Filed: 1981-11-27
Abstract: PURPOSE:To manufacture a hammer which has superior wear resistance and provides superior print quality by plating the printing surface of a hammer made of Ti alloy with Ni, and then forming a hard surfacing layer of an Ni-diffused layer by heat diffusion. CONSTITUTION:A hammer for a drum type line printer is made of Ti alloy and its printing surface is treated by a sand blast to remove the surface oxidized film; and acid pickling is performed with a nitric acid and fluoric acid mixed solution, thus removing the surface oxidized film completely. Then, the printing surface is plated with N. The hammer is held in the inert gas atmosphere in a furnace and heat diffusion is carried out to form a hard surfacing layer formed of an Ni diffused layer. Further, a pure Ni layer remaining on the surface is removed by a sand blast.
