Steel ingot used for forged pipe mould

The invention relates to the field of steel ingot production, in particular to a steel ingot used for a forged pipe mould, and a production method of the steel ingot. A riser accounts for 2%-5% of the total weight of the steel ingot. By controlling the process conditions, the yield of the forged pipe mould is increased by 5%-8%, and the cost of each ton of forged pieces is reduced by RMB 500 yuan. The casting temperature is lowered to 1535 DEG C to 1545 DEG C from 1560 DEG C to 1565 DEG C. meanwhile, the casting time is shortened, segregation of chemical components is reduced, and the C deviation is reduced to +/-0.02 from +/-0.04. The riser accounts for 2%-5% of the total weight of the steel ingot, materials are saved, and the yield is further increased. The gas content is as follows, the content of TO is not larger than 20 ppm, the content of H is not larger than 1.0 ppm, the content of N is not larger than 60 ppm, and the content is obviously reduced compared with existing content. 本发明涉及钢锭生产领域，更具体的讲是种锻造管模用
