为了适应冷轧镀锡机组通过技术改造后可以形成15万吨/年以上生产力的需要,以及为了消除罩式退火炉产生原板严重粘结的缺点,公司曾设想在现有脱脂线线后延建连续退火线的方案,设备立足于国内制造,以便投资最少而获得优质原板;曾对此方案进行过讨论及研究。由于镀锡板原板退火工艺的方向是连续退火,罩式炉必然要被淘汰;但另行选择场地新建一条连续退火线的投资将会很大。因此,依靠自己的力量延建连续退火线是今后冷轧改造取得良好经济效益的有效措施,深入研究很有必要。冷轧脱脂跨原设计就留有增建简单连续退火线的场地。问题是,可否利用原有厂房建成一条现代工艺水平的连续退火线,抑
In order to meet the needs of the cold-rolled tin-plating units that can achieve a production capacity of more than 150,000 tons / year through technological innovation and to eliminate the severe bond of the original panels in the hood annealing furnaces, the company had envisaged the extension of the existing degreasing lines Continuous annealing line programs, equipment based on domestic manufacturing, in order to minimize the investment and access to high-quality original board; this program has been discussed and studied. As the direction of the original tin plate annealing process is continuous annealing, hood furnace will inevitably be eliminated; but the alternative site to create a new continuous annealing line investment will be great. Therefore, relying on their own strength to build a continuous annealing line is an effective measure to achieve good economic returns in the future cold-rolling transformation. It is necessary to conduct further studies. Cold skim across the original design of the left to build a simple continuous annealing line venues. The question is whether to use the original plant to build a continuous annealing line of modern technology,
