阿姆柯钢公司巴尔的摩厂一台价值180万美元的新型旋转加热炉已投入使用。它不仅提高了生产能力,而且改善了不锈钢棒、线材的表面和内部质量。这是萨姆制炉公司设计制造的同类产品中最先进的一种。它可以代替一排6个活底炉(保持其中两个炉子用于低温退火)。该炉热处理盘条时间相当于活底炉的1/3。圆形炉底直径8.2米,旋转一周用55分钟,这就保证了每卷盘条得到均匀的处理。不锈钢盘条和钢丝每卷重量204～226公斤,用运输机送入炉内,放到一个旋转
A $ 1.8 million new revolving furnace at Amcor Steel’s Baltimore plant has been put into operation. It not only improves productivity, but also improves the stainless steel rod, wire surface and internal quality. This is the most advanced one of its kind designed and manufactured by Sam Furnaces. It can replace a row of six active hearth furnaces (keeping two of them for low temperature annealing). The furnace heat treatment wire rod time equivalent to live furnace 1/3. The diameter of the circular hearth is 8.2 meters and it takes 55 minutes to rotate one revolution, which ensures uniform handling of each reel of wire. Stainless steel wire rod and wire weight 204 ~ 226 kg, with the transport aircraft into the furnace, put a rotation
