湘潭风动机械厂的广大职工,在毛主席无产阶级革命路线指引下,发扬“自力更生”、“艰苦奋斗”的精神,利用废旧材料,自行设计,自己动手,用四个月的时间,制造成功了一台Fe—Cr—Al丝烧结炉。为国家节约资金一万余元,并大大提高工作效率,降低了消耗,减轻了工人劳动强度。过去粉末冶金烧结,是在一个做电瓷的小实验土窑进行,产量低、质量差,报废率达50％,工人劳动强度大。本炉主要用于粉末冶金烧结,由预热段、烧结段、冷却段等三段组成。用石墨舟分两段控制温度,采用Φ3的OCr_(25)A1_5电热丝作发热体,表面负荷0.416瓦/厘米~2绕成螺旋体穿入炉膛管壁的孔中,上下各8个,两侧各4个,炉膛管为中性粘土耐火材料作成,炉膛管外
Under the guidance of Chairman Mao’s proletarian revolutionary line, the broad masses of workers and staff of Xiangtan Fengdong Machinery Factory carried forward the spirit of “self-reliance” and “arduous struggle” and used the waste materials to design and do it yourself. In four months, A Fe-Cr-Al wire sintering furnace. Saving more than 10,000 yuan for the country, and greatly improve work efficiency, reduce consumption, reduce the labor intensity of workers. In the past, powder metallurgy sintering was carried out in a small experimental kiln making porcelain. The output was low, the quality was poor, the rejection rate was 50%, and the labor intensity of the workers was large. The furnace is mainly used for powder metallurgy sintering, preheating section, sintering section, cooling section composed of three sections. A graphite boat was used to control the temperature in two stages. The Φ3 OCr_ (25) A1_5 electric heating wire was used as the heating element. The surface load was 0.416 W / cm ~ 2 and the spiral was penetrated into the hole of the furnace tube wall. Each 4, furnace tube made of neutral clay refractory, furnace tube outside
