Abstract

The invention provides a waste heat utilization steel strip heat treatment system. The system comprises an unwinding wheel, a winding wheel and steel strips which are arranged between the unwinding wheel and the winding wheel, wherein a heating furnace and a tempering furnace which correspond to the steel strips are sequentially arranged between the unwinding wheel and the winding wheel; a quenching pressure plate is arranged between the heating furnace and the tempering furnace; a waste heat recovery pressure plate is arranged at the back of the tempering furnace; and a waste heat utilization pressure plate which corresponds to the quenching pressure plate and the waste heat recovery pressure plate are arranged in front of the heating furnace. The steel strips can be preheated by part of waste heat so as to save the heating energy of the steel strips and production cost.

Description

technical field [0001] The invention relates to the field of steel strip heat treatment, in particular to a steel strip heat treatment system utilizing waste heat. Background technique [0002] Energy conservation and emission reduction is a long-term strategic policy for my country's economic and social development, and it is also an extremely urgent task. Recycling waste heat to reduce energy consumption is of great practical significance to my country's strategic policy of energy conservation, emission reduction, and environmental protection development. At the same time, waste heat utilization plays an increasingly important role in improving working conditions, saving energy, increasing production, improving product quality, and reducing production costs. The residual heat of the steel strip refers to the remaining heat of the steel strip after quenching and tempering. After the steel strip is quenched and tempered during heat treatment, its temperature is still above...
