上海钢铁研究所制的“内热式氨分解保护气体发生装置”于一九八一年五月十九日在上海冶金工业局鉴定通过。应邀参加会议的有上海和来自全国各地的十七个单位的三十二位代表。代表们一致认为这台装置是国内首创,性能指标达到了国际同类产品的先进水平。在上海钢铁研究所、上海第三冷轧带钢厂、上海亚洲电焊条厂等单位长期使用,性能稳定,效果良好。一致认为内热式氨分解保护气体发生装置应取代耗能较大的外热式氨分解装置、大部份瓶氢和电解水制氢设
Shanghai Institute of Iron and Steel “internal thermal ammonia decomposition protective gas generator ” in May 19, 1981 in Shanghai Metallurgical Industry Bureau identified through. Thirty-two delegates from Shanghai and from 17 units across the country were invited to the conference. The delegates unanimously agreed that this device is the first in China and its performance indicators have reached the international advanced level of similar products. In the Shanghai Institute of Iron and Steel, Shanghai Third Cold-rolled steel mills, Shanghai Asian welding rod factory and other units long-term use, stable performance, good effect. It was agreed that the internal thermal ammonia decomposition protective gas generator should replace the more energy-consuming external thermal ammonia decomposition device, most of the bottle of hydrogen and electrolyzed water hydrogen plant
