一进步很大,差距不小 1991年我国连铸发展取得了很大进步,连铸坯产量达3685万吨,比上年净增619万吨,连铸比达40.3％,超过了原38％的计划目标;全连铸分厂(车间)又增加了10个,达到24个,共拥有铸机59台,总能力1155万吨/年分别为全国铸机台数及能力的28％和26％;新增连铸机35台,增加连铸坯生产能力658万吨/年。此外,在单流年产量及新建铸机的达产速度方面均有提高,在产品品种、质量上亦有所发展,显示了连铸的全面发展和很大进步。
A great progress, the gap is not small 1991 China’s continuous casting development has made great progress, continuous casting production reached 36.85 million tons, a net increase of 6.19 million tons over the previous year, casting up to 40.3%, more than the original 38% The total continuous casting plant (workshop) has increased by 10 to 24, with a total of 59 casting machine with a total capacity of 11.55 million tons / year, respectively, the number of machines and capacity of 28% and 26% 35 new continuous casting machines were added to increase the continuous casting slab production capacity of 6.58 million tons per year. In addition, both the single-stream annual output and the new-built caster’s production rate have increased, and product varieties and quality have also been developed, showing the all-round development of continuous casting and great progress.
