美国《工业热工》月刊一九七七年十二月报道,美国一家热处理厂新建一座台车式炉,号称是当时美国西南部经营热处理的最大最先进的台车式炉,主要用于大型容器等的正火、退火和消除内应力。炉膛尺寸3.96米宽,4.25米高,17.1米长。造价二十五万美元。由于采用新技术、新设备,它比同样尺寸的常规炉子节省燃料。在投产两个月期间,实测天然气消耗量比常规炉子的估计值节省45％。
According to a monthly report published by the American “Industrial Thermal Workers” in December 1977, a heat treatment plant in the United States built a new trolley furnace, which is known as the largest and most advanced trolley-type furnace for heat treatment in the southwestern United States and was mainly used for large-scale Normalizing of containers, etc., annealing and elimination of internal stresses. Furnace size 3.96 meters wide, 4.25 meters high, 17.1 meters long. Cost 250,000 US dollars. Thanks to the new technology and new equipment, it saves more fuel than conventional furnaces of the same size. During the two months of commissioning, the measured natural gas consumption is estimated to be 45% less than the estimate for conventional furnaces.
