The invention relates to the technical field of metal materials, in particular to a low-compression-ratio thick plate product for a 3,500 mm single-rack furnace coil production line and a control method. The 3,500 mm single-rack furnace coil production line is used for sequentially carrying out the procedures of plate blank cold conveying, heating, rough rolling, intermediate blank cooling, finish rolling, controlled cooling, stack slow cooling and heat treatment normalizing; and the low-compression-ratio thick plate product of the 3500 mm single-rack furnace coil production line is manufactured. The high-strength high-low-temperature-toughness low-compression-ratio thick steel plate is prepared by regulating and controlling the procedures of heating, rough rolling, intermediate billet cooling, finish rolling, controlled cooling, heat treatment normalizing and the like in a 3500 mm single-rack furnace coil production line. 本发明涉及金属材料技术领域，具体涉及一种3500mm单机架炉卷产线低压缩比厚板产品及控制方法，本发明利用3500mm单机架炉卷产线依次进行板坯冷送、加热、粗轧、中间坯冷却、精
