duration of heating

According to the different smelting time characteristic for converter,and the actual production process in cold model experiment,water is used to simulate "molten steel","steel-slag" and "steel-slag-gas" emulsification fused.

根据转炉生产过程中不同冶炼时期的特点,在冷态模型实验过程中充分考虑热态生产的实际情况,提出用水模拟“钢液”、“钢-渣”和“钢-渣-气”乳化熔体,探索实际生产过程中转炉内不同冶炼时期熔池的搅拌混匀特性、喷溅及熔体对炉壁的冲刷作用。

The paper demonstrates after analysis that the main affecting factors of silicon pickup for low carbon and low silicon steel under the present process conditions are the heavy task of desulphurization, large quantity of converter slag and long refining time, and puts forward four improvement measures such as pre-desulphurization treatment of 100% molten iron.

通过对低碳低硅钢增硅问题进行分析,明确了在当前工艺条件下精炼脱S任务重、转炉下渣量大、精炼时间偏长是增硅的主要影响因素,提出了100%铁水预脱硫处理等四条改进措施,[Si]合格率由83。

This resulted in greatly reducing the time of a single heat.

这大大缩短了一炉钢的冶炼时间。
