摘要： PURPOSE:To reduce non-oxidative gas consumption and achieve higher quality of porous hoop sintered substrates by containing a turn roll within the turn roll box connected to the sintering furnaces provided before and behind the turn roll and providing a cooling part at the hoop outlet of the sintering furnace of the rear part. CONSTITUTION:A porous hoop 21 made of metal is passed through a tank 24 to let paste-form sintering metal powder 25 be coated on both surfaces thereof. The coating thickness is controlled with a blade 26. When the hoop is passed through a drying furnace 27 then through the first sintering furnace 29, turn roll 30, second sintering furnace 34, cooling air channel 44, the slow-cooled sintering type electrode plate 50 is sent out to the next process. The non-oxidative gas is suppllied from a gas supply port 33 into the turn roll box 32 and is led to a safe place by ducts 38, 39 through the gas seals 40, 41 of the first and second core pipes 31, 35. The non- oxidative gas is also supplied from a supply port 45 to a skirt part 37 via wind channel 44 and the cooling water is flowed through a supply port 46 to a discharge port 48. The core tubes 31, 35 and box 32 constitute a hermetic chamber higher than the atmospheric pressure.

摘要： PURPOSE:To make unnecessary the acceleration of the finishing mill, and to contrive the energy saving and the uniformization of the quality, by arranging the reheating furnace internally holding the steel sheet transferrer, between the roughing mill and the finishing mill, in the continuous hot rolling mill. CONSTITUTION:The well-known steel material transferrers 11, 12, 13, are installed between the rear table 5 of the roughing mill and the front table 7 of the finishing mill; the reheating furnace or the warming furnace 15, provided with multiple unit heaters 16 respectively independent of each other, is arranged so as to cover above transferrers 12, 13. The temperature of the intermediate rolled material 14 is measured by the thermometer 4, and the rolled material 14 is heated to a uniform temperature by the heaters 16 correspondingly to the measured temperature; and the material 14 is supplied to the finishing mill 6. As a result, the acceleration of the finishing mill 6 becomes unnecessary. Moreover, the heat radiation of the material 14 in the transferrers 12, 13, is reduced, and the temperature of the heating furnace 2 can be lowered to contrive the energy saving; besides, the reduction of skid marks and the uniformization of the quality become possible.
