南昌钢铁厂在转炉普通铸铁钢锭模上,采用减薄模壁厚度技术获得成功,从而大大降低了钢锭模的消耗。 钢锭模是当前冶金行业消耗最大的一种生产工具。1989年,这个厂转炉钢锭模单耗平均为38.1公斤/吨,与冶金部要求的单耗17公斤/吨以下尚有很大差距。1990年初,该厂备件管理人员围绕降低钢锭模消耗展开了攻关活动。他们经过二次改型后,运用价值工程优选出减薄模壁厚度10毫米的方案,于8月份正始投入使用。模重由740公斤/支减至565公斤/支,使用次数由32次/支增至68次/支,单耗由38.1公斤/吨降至13.69公斤/吨。按转炉年产6万吨钢计算,每年可降低消耗99.88万元。目前,他们已着手将这一成果运用于电炉钢锭模。
Nanchang Iron and Steel Plant in the ordinary cast iron ingots mold, the use of thin wall thickness reduction technology success, thus greatly reducing the ingot mold consumption. Ingot mold is currently the largest consumption of metallurgical industry, a production tool. In 1989, the unit consumption of converter ingot molds was 38.1 kg / t on average, which is still far behind the unit consumption of 17 kg / t required by the Ministry of Metallurgy. In early 1990, the plant spare parts management personnel to reduce the consumption of steel ingot carried out research activities. After their second modification, they optimized the project of reducing the thickness of the die wall by 10 mm using value engineering and started operation in August. Modulus weight from 740 kg / support to 565 kg / support, the number of uses from 32 / support to 68 / support, unit consumption from 38.1 kg / ton down to 13.69 kg / ton. Calculated by the converter with an annual output of 60,000 tons of steel, annual reduction of 998,800 yuan. At present, they have begun to use this result in the electric furnace ingot mold.
