在以华国锋主席为首的党中央英明领导下,彻成粉碎了“四人帮”反党夺权的反革命阴谋,全国上下大快人心,工农业生产的形势越来越好。 在毛主席“独立自主,自力更生”方针指引下上海电热电器厂和上海硅酸盐研究所等单位的广大工人、干部和技术人员深入生产实际,采用“三结合”的形式试制成功HDO-13J型和HDO-6J型高温红外线电加热器,供三十万吨合成氨工程大型容器局部消除应力和焊前预热等作业使用。在此基础上又研究了纺织、食品、印刷等行业用的远红外管状电加热器,在节电方面初步做了一些工作。本文对HDO-13J型红外线电加热器和SRW1-220/1.2型远红外管状电热元件的试制及应用情况作一小结以供有关兄弟单位参考。
Under the wise leadership of the Party Central Committee led by Chairman Hua Guofeng, the counterrevolutionary conspiracy against the Party's seizure of power by the “gang of four” has been thoroughly shattered. The situation in the industrial and agricultural production is getting better and better. Under the guidance of Chairman Mao's principle of “independence and self-reliance,” the vast numbers of workers, cadres and technicians from Shanghai Electric Appliance Factory and Shanghai Silicate Research Institute, under the guidance of the principle of “Three Combinations,” successfully produced HDO-13J and HDO-6J-type high-temperature infrared heater for 300,000 tons of synthetic ammonia engineering large containers locally eliminate stress and welding preheating and other operations. On this basis, we have also studied the far-infrared tubular electric heater used in the textile, foodstuff, printing and other industries, and initially done some work in electricity saving. This article on the HDO-13J-type infrared heater and SRW1-220 / 1.2-type far-infrared tubular heating element trial and application of a summary for the reference of the brother unit.
