furnace shell

Blast furnace shell will get into plastic stress and temperature distortion, and then thermal elasticity is inapplicability.

在炉壳温度较高或者炉内压力比较大的情况下炉壳会进入塑性变形状态，热弹性力学已不适用。

As hole-intensive, it will cause stress concentration on the local area after opening; stress on local area reaches its yield possibly under changes in the status of the furnace and the corresponding fluctuations of the furnace shell in the circumstances, which entered the plastic state.

由于孔洞密集，开孔后在局部区域会引起应力集中；在炉况变化、炉壳受力相应波动的情况下导致局部区域应力可能会提前到达屈服，从而进入塑性状态。

Also included is a thermometer hole which thrills through the furnace shell to extend in the refractory layer.

还包括测温孔，测温孔穿过炉壳伸入耐火层内。
