Influence of Refractory᾽s Poisson’s Ratio on the Stress Field of COREX Gasifier Top

Abstract:

Poisson’s ratio and elastic modulus are important parameters reflecting resistance to deformation and mechanical properties of refractory. In this paper the effect of posision’s ratio and elastic modulus on the stress field of the top of gasifier was investigated by numerical simulation. It is concluded that when for working lining poisson’s ratio is 0.15, elastic modulus is 128.8×107Pa, for permanent lining poisson's ratio is 0.1, the elastic modulus of 47.7 × 10⁷Pa, the stress of the top is smaller and it is conductive to long-time use of top refractory.
