根据国家科委14项技术政策规定:加速节能技术改造,限期淘汰效率低的高耗能设备,禁止生产和使用低效耗能设备。国务院又曾以87—2号命令限期停止使用并更换高耗能的电阻降压式多头焊机和旋转式直流弧焊机。已列为国家12大耗能产品之一的电焊机,年耗电量估计不低于15亿度。例如制造一艘万吨级油轮,因焊接耗电就达60余万度,然而目前我国造船工业中,绝大多数船厂仍在使用高能耗的旋转式直流弧焊机,其拥有量超过焊机总占有量的50％。为此,东海电焊机厂1988年根据浙江省机
According to the State Science and Technology Commission 14 technical policies and regulations: accelerate energy-saving technological transformation, the deadline elimination of inefficient high-energy-consuming equipment, prohibit the production and use of inefficient energy-consuming equipment. The State Council once again ordered to stop using 87-2 orders and replace the energy-saving resistance step-down multi-head welding machine and rotary DC arc welding machine. Has been listed as one of the 12 major energy-consuming products welding machine, the estimated annual power consumption of not less than 1.5 billion degrees. For example, to manufacture a 10,000-ton oil tankers, it consumes more than 600,000 kilowatt-hours of power because of welding. However, at present, the vast majority of shipyards in China are still using rotary DC arc welders with high energy consumption. The total amount of 50%. To this end, Tokai welding machine factory in 1988 according to Zhejiang Province machine
