摘要： Modifications are provided to a standard, batch type industrial heat treat furnace of a hot wall design which permit the furnace to be operated efficiently at high temperatures. The furnace is of a cylindrical design having a forward heat treat chamber and a rearward plenum chamber with a flat bulkhead plate in-between the chambers. The bulkhead has exit and inlet openings permitting wind mass to flow to the heat treat chamber and back to the plenum chamber. The bulkhead has a plurality of radially extending slits formed therein which permit the bulkhead to remain flat despite temperature and pressure gradients resulting in expansion/contraction of the bulkhead. Additionally, the furnace includes a closed end muffle within the heat treat chamber into which work to be heat treated is placed. A water cooled spring biasing support is provided for the closed end of the muffle to resist downward deformation of the muffle at high temperatures. The furnace additionally includes a heat shield circumscribing the furnace casing to provide a cooling air space for preheating burner combustion air while minimizing heat losses and the cost of furnace insulation.
摘要翻译：修改提供给允许炉在高温下有效操作的热壁设计的标准批量型工业热处理炉。该炉具有圆柱形设计，其具有正向热处理室和在室之间具有平坦隔板的后部增压室。隔板具有出口和入口开口，允许风质流到热处理室并返回到增压室。隔板具有形成在其中的多个径向延伸的狭缝，其允许舱壁保持平坦，尽管温度和压力梯度导致舱壁的膨胀/收缩。此外，炉子包括热处理室内的封闭端马弗炉，放置待热处理的工件。为马弗炉的封闭端提供水冷弹簧偏压支架，以抵抗马弗炉在高温下的向下变形。该炉还包括围绕炉壳的隔热罩，以提供用于预热燃烧器燃烧空气的冷却空气空间，同时最小化热损失和炉绝缘成本。

摘要： An improved cooling cover is disclosed for use in bell shaped annealing furnaces. The cooling cover includes a jet nozzle orifice arrangement which develops jet streams from a low pressurized supply of air at ambient temperature in the plenum chamber of the cooling cover. A multitude of free standing jet streams thus impinge the inner cover of the bell shaped annealing stand to produce improved cooling times. Importantly, the plenum chamber includes strategically placed axial jet pump outlets which are effective to draw the jet streams from the cooling cover after they have been in heat transfer contact with the inner cover in a distribution pattern which is not altered so that the work or coils within the inner cover can be more uniformly cooled than heretofore possible. The spent jet streams are withdrawn from the cooling cover in a manner which does not affect the initial impact of the jets with the inner cover while establishing a neutral to slight under pressure at the base of the cooling cover to prevent sand seal upset and hot gas backwash.
摘要翻译：公开了一种用于钟形退火炉的改进的冷却盖。冷却盖包括喷射喷嘴孔布置，其在环境温度下从冷却盖的增压室中的低压空气供应产生喷射流。因此，许多独立的喷射流冲击钟形退火台的内盖以产生改善的冷却时间。重要的是，增压室包括有策略地放置的轴向喷射泵出口，其有效地在与未被改变的分布图案与内盖热传递接触之后从冷却盖抽出喷射流，使得工作或线圈在内盖内可以比以前更加均匀地冷却。废喷射流以不影响喷嘴与内盖的初始冲击的方式从冷却盖中取出，同时在冷却盖的底部处建立中性至轻微的压力，以防止砂封不适和热气体反洗

摘要： An industrial electrical, vacuum furnace for ion processing of work is provided with an improved feed-through interlock and insulator arrangement. A sealed interlock chamber on the furnace door is in fluid communication with the furnace's heat treat chamber. A bellows outside of the interlock chamber is in fluid communication therewith. When a vacuum is drawn in the heat treat chamber, the bellows distends into a collapsed position to provide a firmly clamped electrical connection with the feed-through which extends through the door into the interlock chamber. The feed-through is thus pinned by the bellows at one end and a V-shaped pulley guide arrangement within the furnace controls thermal distortion of the feed-through. The insulator arrangement includes a plurality of interlocking, ceramic caps or spacers which are stacked one on top of the other to define tortuous paths or gaps therebetween which prevent electrically conductive material deposited thereon during the ionizing process from establishing an electrically conductive path along which or as a result thereof an ion glow discharge or arcing or short circuiting could occur.
