Abstract

本实用新型涉及一种复合导卫板,它是由冲击韧 性好的铸钢基体上用高温耐磨焊条堆焊成工作面层, 故具有良好的耐磨性和抗冲击性,且易修复而成本又 不太高、加工工艺简单。性能大大优于一般铸铁、铸 钢导卫板,比铬镍合金导卫板抗冲击且成本低。

Description

本实用新型涉及一种复合导卫板。
目前治金工业轧机用导卫板按材质分为三种:一般铸铁、铸钢、合金铸铁。它们的局限和不足是:一般铸铁导卫板很不耐磨、不抗冲击;铸钢导卫板抗冲击但不耐磨;合金铸铁虽然耐磨但不抗冲击且成本高。导卫板是治金工业轧机用消耗量很大的一种工艺备件。
本实用新型的目的就是为解决上述问题,提供一种既耐磨、抗冲击、易修复而成本又不太高的新型堆焊复合导卫板。
本实用新型原目的是这样达到的
将高温耐磨焊条堆焊于铸钢导卫板的工作面表层,即构成了新型的耐磨、抗冲击、易修复且成本又不太高的导卫板。本实用新型比目前国内实验的耐磨块和铸铁(钢)基体组合式(紧固件连接组合式或镶嵌铸造组合式)耐磨面层与基体结合牢固、制造工艺简单且现场修复方便。
下面将结合附图做进一步详细的说明。
附图是本实作新型的一种实施例结构剖面图。
如图所示:基体(2)是铸钢材质的,为使导卫板有很好的耐磨性,在其工作面轧件主要磨损部位表层用高温耐磨焊条堆焊成耐磨的工作面层(1),这样就达到了我们的目的。
本实用新型的试样已在济南钢铁总厂轧钢分厂Φ750初轧机后Φ500轧机中上棍和天津钢厂初轧厂Φ750初轧机后Φ550轧机中上棍做成卫板进行了实验,比原ZG45铸钢材质的卫板提高寿命7倍,可节约备件费70%,并可提高轧机作业率、减轻工人劳动强度。
上述实验也证明,本实用新型是一种较理想的治金工业轧机用导卫板。
本实用新型的实施应用,就会产生良好的经济、社会效益。
