Abstract

Abstract

In this paper,the sintering layers of the coating compounded by different refractories were observed with SEM, and the relation between the state of the coating layers and the surface quality of the casting steel pipes have been studied. It is put forward that the thermal conductivity, the sintering degree of coating can effect the surface quality of the casting pipes directly.Reducing the thermal conductivity and the sintering degree of coating can avoid the pinholes.
