摘要： Spaced apart packs of closely spaced steel or other metallic rods, tubes or other elongate articles are annealed or otherwise heat treated by advancing them step by step by a walking beam mechanism through a chamber having a series of independently temperature controlled zones along the path of travel, the articles being disposed horizontally and transversely of the path of travel. The atmosphere within each zone is recirculated therein independently of the recirculation of atmosphere within adjacent zones and without substantial mixing of the atmosphere within adjacent zones. Packs are introduced into the chamber from a bed of powered rollers adjacent to the inlet end of the chamber partly by pivoting the free ends of extensions of the movable rails of the walking beam mechanism, to lift a pack above the level of the powered rollers so that it can translate with the other packs within the chamber, and partly by pusher heads which slidably engage the movable rail extensions and which are reciprocable with respect thereto. The chamber is preferably utilized to process articles which retain a significant degree of latent heat from a manufacturing or other processing operation to avoid the need for a significant degree of reheating of the articles within the chamber and without substantial intermixing of the atmosphere from adjacent zones.
摘要翻译： 间隔开的紧密间隔的钢包或其他金属棒，管或其他细长制品的包装通过步进梁机构一步一步地沿着行进路径通过具有一系列独立温度控制区域的室而进行退火或另外热处理 所述物品被水平地和横向地设置在所述行进路径上。 每个区域内的气氛不依赖于相邻区域内的大气的再循环，而不在相邻区域内大气中的大量混合。 包装从邻近室的入口端的动力滚筒床引入室中，部分通过使步进梁机构的可移动轨道的延伸部的自由端枢转，以将动力辊的水平面上方的组件提升 它可以与腔室内的其它包装物一起平移，并且部分地通过可移动地接合活动导轨延伸部并且可相对于其移动的推动头。 优选地，该室用于处理从制造或其它加工操作中保留显着程度的潜热的制品，以避免对室内的制品进行显着程度的再加热，而不会使大气从相邻区域实质上混合。
