中铝旗下一公司开启“静音工厂”生产模式

2016-10-28 16:23:17   千龙网

设备方面,打壳气缸的改造是他们消音的主攻方向。他们根据设备性能及多年的维修经验,在反复推敲和多次试用后,制订了改造方案,在打壳气缸换向阀上加装快速接头改造消音器和扣压气管进行回风消音。同时,在打壳气缸内部火塞和上下端盖之间加装缓冲垫,直接消除了火塞和上下端盖之间的撞击声。

另外,因天车轨道接头处高低不平,天车在行进过程中易造成行动轮磨损、变形从而产生噪音。该厂电解系列维修人员开动脑筋,根据轨道接头大小利用废旧传送带制作了可减震的轨道垫板,大大降低了噪音和行动轮的磨损,延长了使用寿命,以微小的投入,取得了良好效果,可谓是一举两得。

烟气和粉尘的无组织排放是治理和保持现场环境卫生的重要“杀手”,也是电解铝厂急需攻克的又一难题。在新槽投用初期,槽上部三角槽门处的孔洞及16根阳极导杆与槽上部水平罩板之间的缝隙,都易造成烟气和粉尘的漏排。为解决此问题,该公司员工通过反复尝试,利用供料净化区域替换下来的废旧除尘布袋对槽门角部、三角盖板四角和出铝气缸导向座进行密封,同时用保温棉对阳极导杆处进行密封,有效解决了烟气和粉尘的无组织排放,使车间环境大大提升。

历时9个月首获验收成果

在经历了270多个日夜后,9月底,为期两天的验收工作正式开始,两个小组分别对电解槽、多功能天车、电解过程控制、供料净化区域四个大部分十八个可控项进行验收,验收工作按照打分制进行,得分超过90分则可通过。此次验收,电解二系列十工区以91分位居榜首,成为第一个“静音工区”的获得者,其他未通过的工区将继续按照“静音工厂”的标准制订方案,主动提出验收,做到成熟一个工区验收一个工区,直至全系列达标。

现在,当员工们再次走进电解系列时,大家会发现这里的空气清新了,现场明亮了,噪音降低了,甚至走到个别工区,你会明显感觉到整个工区安静得如同没有在生产,只是偶尔会传来几声轻微的打壳声。

如今,在山东华宇电解铝厂“静音工厂”的创建过程中,“静音工区”全覆盖已经不只是一个思路,更是一个目标、一份坚持,电解人将继续以“困难面前不低头,强者面前不认输”的精神风貌坚持不懈地向更高的目标迈进。
