一、概况我厂地处太湖风景区的交通要道,二轧车间是一个轧机为270×3/235×5小型轧钢车间。生产3～12×25～65普碳扁钢,年生能力为三万吨,车间原有一座人工加煤的连续加热炉,有效炉长14.6米,炉内宽2.8米,炉底有效面积为40.88米~2,设计产量8吨/小时,1982年燃煤年均单耗最低时为129.78公斤(实)/吨坯。在生产中,因该炉的燃烧不良,造成严重的环境污染。故于1982年将该加热改造列入厂重点改造项目。经一年零四个月来的生产实践,炉子的运行情况稳定,能够满足轧钢工艺要求,消烟除尘效果明显,达到了国家环保标准,煤耗也比人工加煤时降低。与此同时,既减轻了操作工人的劳动强度,也改善了工作环境,实现了改造设计的目的。
I. Overview I plant is located in the Taihu Lake Scenic Area traffic arteries, rolling mill is a rolling mill for the 270 × 3/235 × 5 small rolling workshop. The production of 3 ~ 12 × 25 ~ 65 Cape carbon flat steel, the annual capacity of 30,000 tons, the workshop original a continuous coal heating furnace, the effective furnace length of 14.6 meters, 2.8 meters wide furnace, furnace floor area of 40.88 M ~ 2, the design output of 8 tons / hour, the average annual consumption of coal in 1982 when the lowest was 129.78 kg (real) / ton billet. In production, due to poor combustion of the furnace, causing serious environmental pollution. Therefore, in 1982 the heating transformation included in the factory key renovation project. After a year and four months of production practice, the operation of the stove is stable, able to meet the requirements of steel rolling process, smoke and dust removal effect is obvious, reached the national environmental standards, coal consumption is also lower than the artificial coal. At the same time, it not only reduces the labor intensity of the operating workers, but also improves the working environment and realizes the goal of transforming the design.
