The service life of ingot molds are closely related to the thermal stress in production. The thermal stress of 4.5t ingot mold of vermicular graphite cast iron was measured directly in steel works.This paper describes the measurement and results. The results show that the maximum tensile stress of 20.61kgf/mm~2 at 350℃ occurs at the bottom of the ingot mold. The bottom of the ingot mold is an important place for vertical crack to be initiated in the ingot molds. The cross crack always appears in the centre of...

The service life of ingot molds are closely related to the thermal stress in production. The thermal stress of 4.5t ingot mold of vermicular graphite cast iron was measured directly in steel works.This paper describes the measurement and results. The results show that the maximum tensile stress of 20.61kgf/mm~2 at 350℃ occurs at the bottom of the ingot mold. The bottom of the ingot mold is an important place for vertical crack to be initiated in the ingot molds. The cross crack always appears in the centre of the ingot mold, where the maximum tensile stress is 8.58kgf/mm~2 and the maximum compression stress is 18.72kgf/mm~2, and generally emerges during its later service. All those parameters can be used as a reference for desingers, producers and users of ingot mold.

钢锭模在浇注钢水以后在钢锭模不同部位所产生的应变和应力情况是钢锭模的设计工作者极为关心的问题。本文叙述了用高温电阻应变片直接测定钢锭模外表面不同部位温度的方法和过程。并提供了4.5t蠕墨铸铁钢锭模在浇注钢水以后钢锭模外表面不同部位的应力值。由于热应力和钢水的静压力综合作用,钢锭模的底部工作条件最为恶劣,在浇钢以后25min;在钢锭模底部的中心位置处产生的最大拉应力值为20.61kgf/mm~2。该部位是产生纵裂的主要发源地,而在钢锭模高度方向的中间部位则受拉、压交变应力,该处是钢锭模产生横裂的主要部位。

In this paper, the dynamical response of shallow-buried box structures by using three different analytical models is analysed and compared on the basis of one - dimensional plane wave theory. These models are the shallow-buried beam model, the rigid structure model and the flexible structure model. Studies show that the interaction coefficient, characterizing the ratio of the dynamical deflection of the roof plate of the structure under compression wave to its static deflection under the maximum compression in the free field, varies with several non-dimensional parameters. This paper gives the principles governing the choice of rigid or flexible model adopted for the response analysis of shallow-buried structures commonly used in china.
