The invention discloses water-based quenching equipment and a water-based quenching method for phi76.2mm steel balls made of GCr15SiMn steel. By the water-based quenching method for the phi76.2mm steel balls made of the GCr15SiMn steel, water-based quenching liquid obtained through reasonable formulation of a water-based quenching agent and water is used as a cooling medium to control the steel ball quenching cooling time and the liquid discharging temperature, and for such steel balls with relatively large specifications, the core cooling rate can be obviously increased, the core structure isguaranteed and the core hardness is improved. 本发明公开了GCr15SiMn钢制φ76.2mm钢球水基淬火设备及淬火方法，GCr15SiMn钢制φ76.mm钢球水基淬火方法，在冷却介质上采用了水基淬火剂和水合理配方得到的水基淬火液，控制钢球的淬火冷却时间和出液温度，对这种规格较大的钢球，能明显提高心部冷却速度，保证心部组织、提高心部硬度。
