膨胀应力 [力] swelling stress
- 防止夹砂缺陷的主要措施是降低型砂的膨胀应力和提高型砂的热湿拉强度。
Reducing expansion stress of the moulding sand and increasing wet tensile strength of moulding sand are the main measures to prevent scab defect. - 研究了转炉炉壳变形的状态及规律,分析了炉体机械应力、温度应力及膨胀应力。
This paper presents the research result about the shell deformation on BOF, mechanical stress, temperature stress and lining expansion stress on BOF. - 可拆衬套在整个行程中引导阀瓣。这个部件完全独立于阀体,因此不会受到膨胀应力的影响而产生变形。
Removable Liner guides the disc throughout the full travel. Being entirely independent of the body, it is not subject to distortion by expansion strains.
