节能水冷式炉底辊
本专利技术涉及一种板带热镀锌加热炉领域,更具体地说,涉及一种板带热镀锌加热炉炉底辊。
技术介绍
目前板带热镀锌加热炉炉底辊多采用水冷却,通过通入冷却水对辊体进行冷却,但这样也带来的问题一是冷却时冷却水带走大量的热量,浪费燃料,二是用水量大,浪费水资源。中国专利201320158192.X公开了一种“节能型螺旋水冷式炉底辊”:辊体内轴向通孔内镶装有细长轴,辊体内轴向通孔内壁设有轴向轴向槽,这样,炉底辊在使用时,冷却水在辊体内壁与细长轴之间的轴向轴向槽流动,用少量的水就能起到对炉底辊的冷却作用,带走热量少,节省燃料,也显著节约了水资源。但这种结构的炉底辊也存在下列缺陷:辊体内轴向通孔内壁轴向轴向槽制造难度大,工艺性差。
技术实现思路
