一、概述上钢三厂第一薄板车间是以生产普碳钢热轧板等为主的一个车间。它拥有6座加热炉,一座常化炉,30座罩式退火炉。轧机为Φ60×1200mm两辊周期式。坯料加热及成品热处理采用本车间生产的发生炉煤气。整个车间年耗煤量为5万吨左右,占全厂总能耗的7%,是一个用能大户。近年来通过抓管理和技术改造等措施,取得了一定的经济效益。本文就薄板加热炉的空、煤气换热器改造的几个阶段进行论述,并从理论上加以探讨。二、空、煤气换热器的作用
First, an overview of the first steel sheet factory on the third plant is the production of carbon steel, such as hot-rolled plate mainly a workshop. It has 6 furnaces, a furnace, 30 hood annealing furnace. Mill Φ60 × 1200mm two-roll cycle type. Billet heating and finished product heat treatment using the workshop production of gas furnace. The entire workshop annual consumption of coal is about 50,000 tons, accounting for 7% of the total plant energy consumption, is a major energy users. In recent years by grasping the management and technical transformation and other measures, has made some economic benefits. In this paper, the thin plate furnace air, gas heat exchanger transformation of several stages are discussed and theoretically to be discussed. Second, empty, the role of gas heat exchanger
