Energy Saving Technology of Rolling Mill System Steel

Recent years, regenerative combustion technology has been widely used in heating equipment. Compared with the heating furnace without waste heat recovery, regenerative heating furnace can save more than 40% energy. However, the investment cost is high, and there is the concept of saving energy without money saving. Recently, double regeneration (preheating gas and air 1000℃) technology is

Rolling Mills Industrial Efficiency Technology & Measures

2017-9-13  In rolling mills, intermediate steel products are given their final shape and dimension in a series of shaping and finishing operations. Most of the slabs are heated in reheating furnaces and rolled into final shape in hot– or cold–rolling or finishing mills. While some products (e.g. reinforcement bars, steel plates) only require hot-rolling, some others may require both hot– and cold

Potential for energy saving and environmental protection

The pickling and cold-rolling operations that are part of integrated flat-steel production plants are mostly perceived as having a low potential for energy saving or energy recovery measures, when compared with those processes in the chain that entail high temperature levels upstream and downstream. But there are still a number of resources within these production units that can provide
