计算结果表明：在用具有不同的导热性能和力学性能的耐火材料砌筑的炉缸内存在著应力集中现象，这是导致高炉炉缸破损的主要原因之一。 |
| 6. | In order to search the demolishing effect pf the thermal stress on the hearth and bottom of the blast furnace , the distribution of temperature field and the thermal stress have been studied with the thermal elastic law and finite element method
摘要为了探讨热应力对不同材质构成的高炉炉缸砖衬的破坏作用，在计算温度场的基础上，应用热弹性理论和有限元法对高炉炉缸进行应力分布计算。 |
| 7. | The problem of monitoring the wear - line of a blast furnace is treated as the inverse problem of the static heat conduction system , and the latter has been turned into the optimization of the squared residual of the measured and calculated temperature at the sensor locations
摘要把确定高炉炉缸炉底热侵蚀边界归结为稳态热传导方程的反问题，并转化为极小化在若干测温点处由设定侵蚀边界对应的偏微分方程边值问题求得的温度与实测温度之间误差的优化问题。 |
| 8. | Abstract : a preliminary investigation was made on hearth damage of a number of furnaces in china , and the analysis and discussion are presented for reasons of hearth damage in this paper . the main reasons of ring crack of the hearth are : 1 . improper physical and chemical properties of baked carbon bricks . 2 . the thermal stress existing in carbon bricks , alumina bricks and the furnace shell . the formation of the ring crack aggravates the abnormal erosion of the hearth
文摘:结合鞍钢2号和7号等高炉和2号高炉的调查结果，对国内部分高炉炉缸破损情况进行初步调查，对炉缸破损原因做了初步分析和讨论，认为造成我国高炉炉缸环形断裂的主要原因是由于碳砖自身物化性能差以及炉缸碳砖和高炉炉壳之间的热应力；环裂的出现加剧了炉缸的异常侵蚀。 |
