文中研討了槽基耐火材料、槽壳結构及槽衬膨脹对炭素槽底上抬的影响。試驗証明,槽衬的体积增大2-3％,不仅能引起槽壳各侧变形,也能使槽底中心部分严重上抬。为减少槽衬变形,减少地脚螺絲和导电棒对槽底上抬的影响,建議把加固梁配置在槽壳的上部;設法使地脚螺絲旣能承受垂直力,又能横移;在导电方面力求金属导电棒不同槽底连在一起,只通过某些点进行导电。 In this paper, the effect of groove-based refractories, tank shell structure and tank liner expansion on the lift of carbon tank bottom is discussed. Test proved that the tank liner 2-3% increase in volume, not only can cause deformation on both sides of the tank, but also make the central part of the tank bottom serious lift. In order to reduce the deformation of the slot liner and reduce the influence of the ground screw and the conductive rod on the elevation of the slot bottom, it is suggested that the reinforcing beam be arranged on the upper part of the slot shell; to try to make the ground screw 旣 to withstand the vertical force and to transversely move; Aspects of the metal conductive rod different tank bottom together, only through certain points for conduction.
