The utility model discloses a leveling liquid spraying device for cold rolling strip production, which comprises an upper and a lower fixed beam and two leveling liquid conveying pipelines respectively connected to the fixed beam. The nozzles are arranged evenly on the leveling liquid conveying pipeline, and the inner diameter of the pipe body in the middle of the liquid conveying pipeline is leveled. The inner diameter of the pipe is larger than that of both ends of the flat liquid conveying pipeline, and the outer side ends of the pipe at both ends of the flat liquid conveying pipeline are respectively connected with the two ends of the fixed beam. The two sides of the pipe in the middle of the flat liquid conveying pipeline are separated from the pipe at both ends of the flat liquid conveying pipeline through flange baffles, and the pipe in the middle of the flat liquid conveying pipeline is connected on the pipe body. An independent liquid inlet pipe is connected between the pipes at the two ends of the leveling liquid conveying pipeline through a bypass pipe. The utility model can reduce the consumption of tempering liquid by about 15%, and the consumption of tempering liquid steel per ton can be reduced to less than 0.5 kg.
【技术实现步骤摘要】
用于冷轧带钢生产的平整液喷射装置
本技术涉及一种用于冷轧带钢生产的平整液喷射装置。
技术介绍
冷轧带钢在平整时需对带钢和工作辊表面喷射平整液,要求喷射到带钢表面的平整液均匀,平整液不能循环使用,八钢冷轧目前生产宽度规格范围是930-1250mm,平整液喷射宽度范围为1300mm,在生产1000mm左右宽度的带钢时,平整液喷射装置上下两端150mm范围喷射的平整液没有利用上,直接排出。不同宽度的钢板采用最大宽度的喷射量,不能实现根据生产钢板的宽度调整平整液喷射范围,平整液浪费大;目前平整液一吨13000元,吨钢平整液消耗在0.7Kg/t以上,国内外平整液消耗在0.4Kg/t以下。另外,平整液排出量增大,增加了废水处理成本。
技术实现思路
本技术的目的在于提供一种用于冷轧带钢生产的平整液喷射装置,在保证喷射到带钢表面平整液均匀的前提下,能够降低平整液消耗,降低企业生产成本。本技术的目的是这样实现的,一种用于冷轧带钢生产的平整液喷射装置,包括上、下部固定梁以及分别连通安装在所述固定梁上的两根水平布置的平整液输送管路,平整液输送管路上均布间隔设置着喷嘴,平整液输送管路中部管体 ...
