秦皇岛市硅铁厂的400KVA电炉于10月18日创造了日产硅铁3.556吨的全国新记录,电耗降低到2900度,质量全部合格。本厂三号炉于20日又以3.852吨的高产成绩重新刷新了全国纪录,电耗降低到2445度,质量全部合格。本厂这次之所以夺得大面积丰收,在技术方面主要采取了下列几项措施: (1)做好准备工作:组成高产检查组,对机器设备、原材料、工具等进行了全面检查,及时完成设备工具的检修、补缺、加工复制并组织了验收,把一切不利因素消灭在高产前夕。在高产时责成专人负责生产要害部位,分关把口。 (2)改造电炉设备:采用了唐山铁厂的生铁加厚把持器。变压器连接铜板的铜线由原来的32丝改用0.7毫米的,从而改变了电力低负荷运行现象,由原来60安培提高到95安培,增强了冶炼强度。在铜线与铜板连接处增加了铜卡头,单股接线改为双股接线,解决了电阻大,烧坏设备的问题。三相电极角度由原来等腰三角形改为等边三角形,解决了配角,扩大了燃烧面。
Qinhuangdao City ferrosilicon 400KVA electric furnace on October 18 to create a 3.556 tons of ferrosilicon in Japan’s new record, power consumption reduced to 2900 degrees, all qualified. Our third furnace on the 20th again to 3.852 tons of high-yielding results to refresh the national record, power consumption reduced to 2445 degrees, all qualified. The reason why the factory has won a large area of harvest, the main technical aspects to take the following measures: (1) do a good job of preparatory work: the formation of high-yield inspection team, a comprehensive inspection of machinery and equipment, raw materials, tools, timely Completion of equipment and tools overhaul, fill a vacancy, processing and copying and organizing the acceptance of all negative factors eliminated in the eve of high yield. Responsible for high-yielding people responsible for the production of vital parts, points off the mouth. (2) transformation of electric furnace equipment: the use of Tangshan Iron Works pig iron thickened gripper. Transformer copper connection copper from the original 32 wire switch to 0.7 mm, thus changing the low-power operation of the phenomenon, from 60 amps to 95 amps, enhanced smelting strength. In the copper and copper connections at the increased copper chuck, single-wire wiring to double-stranded wiring to solve the resistance, burned equipment problems. Three-phase electrode angle from the original isosceles triangle to equilateral triangle, to solve the supporting role, expanding the combustion surface.
