概述了中厚板热处理工艺及设备的发展应用情况，介绍了近年来开发成功的中厚板新型高强度均匀化冷却技术——SuperOLAC及在线热处理技术——HOP(在线淬火及回火工艺)。同时，介绍了国内当前中厚板热处理线的建设和设备配置情况以及国产首套具有自主知识产权的中厚板辊式淬火机设备及应用情况。随着国内中厚板企业冶炼和轧制装备及技术水平的日益提高，中厚板轧后辅助工序和技术，尤其是提高钢板强度和性能等级的轧后热处理技术，已成为国内中厚板生产厂家提高产品档次和竞争力的必然选择。
The development and application of heat treatment technology and facilities for steel plates are reviewed. The SuperOLAC and the online heat treatment process developed by JFE are introduced. The existing domestic plate heat treatment lines and the roller quenching machine with domestic independent intellectual property rights are introduced. Comparing with the already achieved advancement of the steel making and refining and rolling technologies and facilities, the processes after rolling, especially the plate steel heat treatment for increasing steel strength and other performances, are becoming the necessary selection for domestic plate plants to raise their product level and their market competitive power.
