嘉克自动堆焊设备在电力行业的成熟应用

嘉克研制和生产的ARC-NMG7-1/2磨辊/磨盘自动堆焊机是磨辊/盘瓦离线堆焊再制造的专用设备,主要用于煤立磨、水泥生料磨、矿渣磨等的磨辊/盘瓦的堆焊再制造,它科技含量高,自动化程度高,焊接效率高,占地面积小,检修方便,耗电省,能适合多种形状的磨辊/盘瓦的堆焊再制造。

设备自生产以来,曾为国内五大发电集团下属的160多家电厂进行了磨辊盘瓦离线堆焊施工,为磨煤机的正常运转和电厂的节能降耗发挥了巨大的作用。目前在国内电力系统配备我公司生产的ARC-NMG7-1/2磨辊/盘瓦离线自动明弧堆焊机的企业多达80多家,共有200多台套设备在正常运转中。利用该设备对ZGMHPRPTEMHRM等各种不同型号磨煤机的磨辊/盘瓦进行堆焊再制造,有效解决了磨机的日常检修和维护问题,为企业创下了可观的经济效益。   

 

 

 

 

 

 

例如,长春发电设备有限责任公司是生产电力系统,近年来由于优质煤的供应越来越紧张,普通煤对于磨煤机的磨辊、磨盘的使用寿命影响很大,其用户由此提出了更高的要求,这样也迫使磨煤机生产厂家选择更好的材料或更优化的工艺来满足抗磨损的要求。

该厂运用北京嘉克新兴科技有限公司的磨辊/盘瓦电弧熔覆机器人在耐磨件基体表面堆焊一定厚度的耐磨层,使磨辊、磨盘的使用寿命增加到原铸造磨辊、磨盘的1.3-1.5倍甚至更高,由此明显减少电厂更换备件的频率,大大降低电厂的检修费用。这种工艺生产的磨辊由于成本降低、使用寿命提高,由此受到用户的欢迎,也直接提高了磨煤机生产厂家的市场竞争力。

石景山热电厂于20079月购进了第二台由北京嘉克新兴科技有限公司研制生产的磨辊/磨盘自动明弧堆焊机,此前另一台同样的设备已经在该厂运行了一年多。该厂拥有20ZGM95N立式磨煤机,以前磨辊、盘瓦磨损后均报废处理,自从硬面堆焊技术发展起来后开始采用堆焊修复的方式,将磨损后的耐磨件进行堆焊修复,重复使用。和很多电厂一样,该厂购置了两台北京嘉克生产的自动明弧堆焊机,建立了专门的堆焊车间,使磨辊、磨盘的堆焊成为电厂日常运行的部门之一,常年坚持对磨损后的磨辊、磨盘进行堆焊维修,有力的支持了生产,降低了更换备件的成本。

内蒙托克托电厂是华北地区最大的电厂,最初运营时磨辊和磨盘衬板使用一段时间被严重磨损后就更换新品,随着钢材大幅涨价,新品的价格直线上升,使得更换新品的成本越来越高,为了降低成本,也为了资源的再利用,电厂选购了4台嘉克生产的磨辊/磨盘自动明弧堆焊机对磨损件进行堆焊修复。

通过几年来的实践,托克托电厂实现了资源的循环利用,将原来磨损后废弃的磨辊、磨盘衬板采用自动明弧堆焊机进行堆焊修复后再安装到磨机上使用。事实证明,修复后的磨辊比新品的耐磨性能还要好,由此电厂节省了大量资金,创造的经济效益十分可观。
