我厂高速钢和3Cr_2W_8V 钢中钨的分析,原采用光谱摄谱方法进行,时间在25分钟以上,有时误差大于±0.4%。化学重量法分析在40分钟以上,远远满足不了冶炼生产的要求。据统计每延长一分钟的冶炼时间就要损失30余元,每炉钢多用1%的钨铁,将损失100余元的价值。因此必须寻求新的分析方法。二年来我们在上钢五厂等兄弟单位的协助下,初步掌握了高速分析方法,在配合我厂的冶炼生产中取 Our factory analysis of high-speed steel and tungsten 3Cr_2W_8V steel, the original spectral spectroscopy method, the time in more than 25 minutes, sometimes more than ± 0.4% error. Chemical gravimetric analysis of more than 40 minutes, far from meeting the requirements of smelting production. According to the statistics, for every one minute extension, the smelting time will have to be lost by more than 30 yuan. The extra 1% tungsten steel per furnace will lose the value of more than 100 yuan. Therefore, new analytical methods must be sought. In the past two years, with the help of our sister companies such as Wuchang Steel Co., Ltd., we have initially mastered the high-speed analysis methods and taken in cooperation with the smelting production of our factory
