石家庄大阳矿山机械

大阳科技开发和生产实力雄厚，拥有多项国家发明专利。以截齿专利技术为主体，生产矿用截齿、工程用截齿、公路铣刨截齿及全岩隧道掘进截齿。还为矿山提供非标专用设备和技术的设计开发。

我公司开发的专利(专利号.9) 新产品犀牛截齿，打破了提高合金齿尖周围的齿体硬度以增强其耐磨性的传统思维方式，完全改变了截齿的结构形式，在主合金尖周围镶有若干副合金尖，使用中副合金尖能有效保护钢质基体，增加耐磨性，这一改变大幅度提高了截齿寿命，实现长效、高效、可靠的采割和掘进。
With patented technology, DAYANG has developed full rang of conical tools covering coal cutting bit tool, road milling pick, tunneling PCD tool, as well as tool and pick for construction industry, under the brand of DAYANG RHINO.

The patented conical tool (P.N.: .9 ) developed by Dayang Company breaks through the conventional single-tip structure, embedding auxiliary carbide tips around the main tip. The auxiliary tips provide better protection of brazed joint and slow steel wash. The patented design profoundly elongates the tool life and helps to realize high-efficient, reliable cutting and excavation.
