The aim of the study is the production of the experimental lot of coil and plate rolled products with dimensions of 5$\times$1500 mm of high-strength steel of grade type 32NiCrMoV9 in the conditions by means of the available rolling mill equipment. In the work, the technological analysis is carried out, the technological scheme of plate production is defined, and the verification of equipment technical capabilities is carried out. The production scheme of plate products is proposed and includes preliminary rolling of continuous casting slabs at the plate rolling mill 3600 with obtaining of 130 mm thickness rolled slabs, rolling of coils at the strip mill 1700, annealing in the hood type furnaces, and cutting by plates at the crosscutting machine. Applying mathematical modelling methods, the technological recommendations are developed for coils’ production from high-strength steel of grade type 32NiCrMoV9 at the rolling mill 1700 that includes temperature–deformation and speed-rolling schedules aimed at providing inherited better ballistic results of the final product. The experimental lot of coils is produced in the conditions of strip rolling mill 1700. As defined, the rolling process at the rolling mill 1700 is accompanied by the increased loading level on the main engines in roughing stands, while complying with defined limits of rolling force. The mechanical-tests’ results have determined that, after coil annealing, the hardness level of high-strength steel of grade type 32NiCrMoV9 is decreased to 22–24 $HRC$ that is lower than blades’ hardness and allows to cut on plates with dimensions of 5$\times$1500$\times$6000 mm at the available cross-cutting machine. Levelling of plates with high levels of yield and tensile strength after annealing is performed with passes quantity increased up to 7–9, and force is decreased accordingly.
