摘要
Abstract
The effects of contents of expanded graphite on the microstructure,mechanical properties and thermal shock resistance of low-carbon containing Al2O3-C refractories were firstly investigated. Accordingly,the field service behavior of Al2O3-C slide gates with proper content of expanded graphite addition was further evaluated.The results show that expanded graphite could stimulate the growth of SiC whiskers under high temperature.Attributing to the synergic strengthening and toughening effects of SiC whiskers and expanded graphite, the residual strength increases from 4.87 MPa to 9.31 MPa, correspondingly,the residual strength ratio varies from 38%to 54%.Also,the pilot test reveals that the average service lives of 0.5wt% expanded graphite containing Al2O3-ZrO2-C slide gates are 0.77 times longer than the traditional ones.关键词
