The invention relates to glass clinker added into peritectic steel casting powder. The glass clinker comprises, by weight, 78.00-86.00 Wt% of gold and copper tailings, 5.00-10.00 Wt% of SiO2, 5.00-9.00 Wt% of CaF2, 1.00-2.00 Wt% of BaO, 0.50-1.50 Wt% of CO2O3, 0-0.2 Wt% of MnO2 and 0-0.1 Wt% of Ni2O3. In the using process, the weight percentage meets the requirement of 100 Wt%. The composite peritectic steel casting powder with excellent performance can be obtained by ball milling and even mixing of 40.00-60.00 Wt% of the peritectic steel casting powder, 30.00-50.00 Wt% of the prepared glass clinker and 3.00-12.00 Wt% of carbon dust. The composite peritectic steel casting powder has the advantages of being high in glass forming speed, high in crystallization rate, dark black in color, low in density of heat flow, small in release gas amount in the using process, even in slag film, capable of obviously reducing longitudinal cracking of peritectic steel casting blank and the like.
