过小的转炉容量不仅操作不稳定,而且经济指标差。因此,我国大量的小转炉都面临逐步增大容量的发展趋势。长治钢厂通过挖潜,成功地将6t小转炉改大至10t,并且投资少,改造周期短。做到当年改造不减产反而增产,只需半年即可偿还全部投资费用。面对我国众多转炉需要扩大容积的情况,长治钢厂的经验是很实用的。 Too small converter capacity not only unstable operation, but also poor economic indicators. Therefore, a large number of our small converter are facing the trend of increasing capacity gradually. Changzhi steel mills by tapping the potential, the successful small 6t converter to 10t, and less investment, transformation cycle is short. In the same year, it will increase production instead of reducing production, and will only pay for the entire investment in half a year. The face of many of our converter needs to expand the volume of the situation, the experience of Changzhi Steel is very useful.
