The invention discloses liquid steel casting equipment. The liquid steel casting equipment comprises an ingot mold, wherein the upper part of the ingot mold is provided with a hot top; the ingot mold is arranged on an ingot mold base plate; a steel flow channel is formed in the ingot mold base plate, is communicated with a central casting pipe arranged on one side of an ingot mold body and is communicated with casting gates at the bottom of the ingot mold; and at least one casting gate is formed at the position which is deviated from the bottom center of the ingot mold. The liquid steel casting equipment can prevent the phenomenon of slag entrainment in the process of casting liquid steel by changing the position and the quantity of the ingot mold casting gates, deviating the casting gates from the bottom center or increasing a plurality of casting gates, changes the flow field distribution and the temperature field distribution of the liquid steel inside the ingot mold in the process of casting the liquid steel or after the casting, overcomes the defects of center segregation and loosing of steel ingots and can change the segregation positions of the steel ingots to make a segregation off center close to a steel ingot rolling surface at the same time.
