上半年,全国生产钢2552.50万吨,其中重点企业生产钢1867.43万吨(内含平炉钢593.92万吨、电炉钢219.07万吨、转炉钢1053.61万吨)。钢产量中包括低合金钢256.12万吨,均创最好水平。全国生产连铸坯298.93万吨(连铸比11.71％),其中重点企业的连铸坯产量235.47吨(连铸比12.6％),均超去年同期水平。平炉的利用系数、钢锭合格率、重油单耗、按计划钢种出钢率,氧气顶吹转炉的利用系数、炉衬寿命、废钢比,连铸坯合
In the first half of the year, 25.525 million tons of steel were produced domestically, among which 18.6743 million tons were made by key enterprises (including 5.9392 million tons of open hearth steel, 2.197 million tons of electric furnace steel and 10.5361 million tons of converter steel). Steel production includes 2,561,200 tons of low-alloy steel, both the best level. The country produced 2,989,300 tons of continuous casting billet (continuous casting ratio of 11.71%), of which 235.47 tons of continuous casting slabs by key enterprises (continuous casting ratio of 12.6%) surpassed the same period of last year. Flat furnace utilization factor, ingot pass rate, heavy oil unit consumption, according to the planned steel tapping rate, oxygen top blowing converter utilization factor, lining life, scrap ratio, continuous casting billet
