今年二月下旬有机会参加了冶金部平炉热工和铸锭工作组,到天津,重庆,武汉,大冶和上海五个地区,8个炼钢厂(或平炉车间)。现介绍一些有关平炉热工的技术见闻。几年来各厂在平炉的热工管理和炉体维获方面取到了很大的成绩,突出的表现是:炉顶寿命大幅度提高和燃料消耗量大幅度的降低,天津的炉顶寿命已达1835炉。有的厂在吸取天津炉顶长寿经验的基础上,通过一系列的试验研究,又进一步改进了吊挂结构和砌砖方法,使炉顶
In late February of this year, they had the opportunity to participate in the open hearth furnace and ingot working group of the Ministry of Metallurgy, and to eight steel mills (or flat-hearth workshops) in five districts of Tianjin, Chongqing, Wuhan, Daye and Shanghai. Here are some technical knowledge about the hearth thermotechnical. In recent years, the plants have achieved great success in the thermal management of flat hearth furnaces and in the dimension of the furnace. The outstanding performance is that the roof life is greatly increased and the fuel consumption is greatly reduced, and the roof life in Tianjin has reached 1835 furnace. Some plants draw on the experience of Tianjin roof longevity, through a series of experimental studies, and further improve the hanging structure and brick method, so that the roof
