The invention relates to special continuous casting crystallizer casting powder for ESP low carbon, and belongs to the field of metallurgy accessories. The casting powder comprises chemical componentsincluding, by weight, 28-33 parts of CaO, 22-29 parts of SiO2, 4.5-7.5 parts of MgO, 4.5-7 parts of Al2O3, 7-10 parts of Na2O, 8-11 parts of F, 0.3-1.5 parts of B2O3, 0.5-1 part of Li2O and 1-3.5 parts of C. The casting powder has the low melting temperature, low viscosity and high melting speed, the casting powder can be rapidly consumed when the continuous casting pulling rate is 5-7 m/min, andaccordingly heat transfer and lubricating performance between a continuous casting blank shell and a crystallizer copper plate are guaranteed.
