Custom Rolling Mill Machine

High-speed rolling technology
The linear speed of modern hot continuous rolling mills can reach 25-30 meters per second, and that of cold rolling mills can exceed 40 meters per second. The annual production capacity of a single production line has exceeded 5 million tons. Through multi-stand headless rolling technology (such as ESP production lines), steel strips can be continuously rolled, eliminating the traditional pickling and annealing processes, and the production cycle is shortened by 70%.
Process Integration Optimization ‌
The Hot Loading and hot feeding (HDR) technology is adopted to directly feed the continuous casting billets into the rolling mill at a temperature above 800℃, reducing the energy consumption of secondary heating (saving 20%-30% of energy). It is directly connected with the continuous casting process to form a "one-tank through" process, reducing the idle waiting time.
Organizational performance optimization ‌
Control rolling technology refines austenite grains to below 5μm by adjusting the final rolling temperature and cooling rate, thereby enhancing the strength and toughness of steel.
Asynchronous rolling (with a working roll speed difference of 10%-30%) introduces shear strain, reducing the anisotropy index of aluminum alloy sheets to below 1.1 and improving deep drawing performance (for automotive body panels).
Compound Rolling Innovation ‌
Vacuum rolling composite technology enables the combination of dissimilar metals such as titanium/steel and aluminum/magnesium, with an interfacial strength of ≥200MPa (such as composite plates used in nuclear power). The thickness of copper foil rolling can reach 6μm (for the current collector of new energy batteries).
Rapid specification change technology
The fully hydraulic rolling mill can complete the switching of parameters such as roll gap and tension within 15 minutes through the preset rolling force curve (traditional mechanical adjustment takes 2 hours), and supports small-batch and multi-variety production (such as home appliance plates → automotive plates).
Recycling energy ‌
Rolling waste heat recovery systems (such as ORC low-temperature generator sets) convert flue gas above 400℃ into electrical energy, with a recovery efficiency of over 20%.
The centralized filtration system for cold-rolled emulsion achieves an oil-water separation rate of 99% and a recycling rate of over 95%.
Lightweight material processing ‌
Magnesium alloy warm rolling technology (200-300℃) reduces the rolling force by 40%, promoting the weight reduction of automobiles (for every 10% weight reduction, fuel consumption can be reduced by 6%-8%).
Through the above technological innovations, modern rolling mills are transforming from "mass manufacturing" to "precision intelligent manufacturing", becoming the core driving force for the upgrading of high-end manufacturing.
