Abstract: The biggest allowable level of chrome residue in mixed batch of glass was studied，so as to improve the handling efficiency in the vitrification process of chrome residue.Glass formation regulation and doping ratio of chrome residue were analyzed by making use of CaO-Al2O3-SiO2 phase diagram，and X-ray diffraction analyzer was also used to determine the degree of vitrification.Research results showed that the theoretical doping ratio of chrome residue in mixed batch can reach 89.11%（mass fraction），while bauxite as composition-regulating raw material；In consideration of the influence of melting conditions on serving life of glass kiln，about 57%（mass fraction） of the doping ratio was proper；If adding flux and cations with high polarizability in mixed batch，the doping ratio can reach 65.6%（mass fraction）.
