CN209124874U 一种立磨耐磨辊套 有权

一种立磨耐磨辊套
摘要：
本实用新型提供了一种立磨耐磨辊套，由自内向外依次设置的普通铸钢层和耐磨铸钢层组成，所述普通铸钢层的材质为ZG20Mn铸钢，所述耐磨铸钢层材质为合金耐磨铸钢；所述辊套的外表面还均匀镶铸有若干硬质合金柱，所述硬质合金柱的顶面与所述耐磨铸钢层的外表面平齐，硬质合金柱的底面穿过所述耐磨铸钢层并伸入到所述普通铸钢层内。经测试，本实用新型所提供的辊套的使用寿命在三年以上，如果作为轮胎形辊套时考虑双面使用，其可以使用六年以上。(ESM)同样的发明创造已同日申请发明专利
摘要（英）：

The utility model provides a vertical mill wear-resisting roller sleeve which is composed of a common cast steel layer and a wear-resisting cast steel layer which are sequentially arranged from insideto outside, the common cast steel layer is made of ZG20Mn cast steel, and the wear-resisting cast steel layer is made of alloy wear-resisting cast steel. A plurality of hard alloy columns are furtherevenly cast in the outer surface of the roller sleeve, the top faces of the hard alloy columns are flush with the outer surface of the abrasion-resistant cast steel layer, and the bottom faces of thehard alloy columns penetrate through the abrasion-resistant cast steel layer and extend into the common cast steel layer. Tests show that the service life of the roller sleeve provided by the utilitymodel is more than three years, and the roller sleeve can be used for more than six years if the roller sleeve is used as a tire-shaped roller sleeve in consideration of double-sided use.
