1.目的二转炉车间目前有25吨氧气顶吹转炉三座,配置连铸机四台,1976年1～10月生产连铸坯26.5万吨,连铸比49.4％。十年来连铸生产实践证明,连铸机浇注钢液温度正常与否是确保正常生产的重要条件之一。钢液温度高,铸坯质量低,如产生夹杂、裂纹、缩孔等,拉速慢,容易产生漏钢事故。而钢液温度偏低,容易造成水口堵塞停浇。故必须摸索合宜的浇注钢液温度。根据资料,国内外有些
1. The purpose of the second converter workshop currently has 25 tons of top-blown oxygen converter three, equipped with four caster, from January 1976 to January production of 265,000 tons of continuous casting, continuous casting 49.4%. Continuous casting production over the past decade proved that continuous casting machine pouring molten steel temperature is normal or not to ensure that one of the important conditions for normal production. Molten steel temperature is high, slab quality is low, such as inclusions, cracks, shrinkage and so on, slow speed, prone to breakout accidents. The liquid steel temperature is low, easily lead to block the nozzle blocked. Therefore, we must explore the appropriate pouring molten steel temperature. According to the information, some at home and abroad
