铸铁锅是人们生活中不可缺少的炊具之一。全国每年大约需要七千万口铁锅。铸铁锅的材料一般都是低牌号的灰口铁,相当于HT10—26,强度低,不耐氧化,寿命短。1982年3月开始,我们同兴和县铸造厂合作,研制稀土合金铸铁锅。同年10月,内蒙古自治区经委等单位召开了鉴定会,批准正式投入生产。 Cast iron pan is one of the indispensable cooking utensils in people’s life. The country needs about 70 million woks a year. Cast iron pot materials are generally low-grade gray iron, the equivalent of HT10-26, low strength, oxidation resistance, short life expectancy. Since March 1982, we have cooperated with Xinghe County foundry to develop rare earth alloy cast iron pot. In October the same year, Inner Mongolia Autonomous Region Economic Commission and other units held an appraisal meeting, approved the formal production.
