摘　　要：选取辊式淬火机为研究对象,建立了高压喷水区钢板冷却过程的传热模型,模拟了钢板在淬火冷却过程中的温度分布。基于传热过程数学模型,并考虑淬火工艺要求和设备条件的限制,设计了两种控冷方案并对高压喷水区水流量和辊道速度进行了优化。结果显示,两种优化的设定方案均可满足工艺要求,随钢板厚度的增加,辊道速度均呈指数形式下降,总水消耗量均呈指数形式增加,且方案二更为节水。Selecting roller-type quenching machine as the research object, the heat transfer model was established to simulate the temperature distribution of the plate during the quenching process at high-pressure water injection zone. Two c0ntrolled cooling process schemes were designed to optimize the water flow and roller velocity based on the heat transfer process mathematical model and combined with quenching process requirements and equipment limitations. The results show that both optimized schemes can meet the technical requirements, and the roller velocity decreases exponentially with the increase of the plate thickness, meanwhile the total water consumption increases exponentially. Furthermore, the scheme 2 is more water-saving than scheme 1.
