摘要
导板是不锈钢管轧机中的关键易损零件 ,在 110 0℃～ 12 0 0℃温度下长期受钢坯的冲击、摩擦、挤压和冷却水周期性激冷。为了取代其昂贵的高温合金材质 ,研制了一种与RTCr - 34相仿 ,加入Ni、Ti、Re和Al的高铬铸铁 ,并通过适宜的热处理工艺提高其综合性能。试验证明 ,这种高铬铸铁具有良好的高温抗磨性、足够的强韧性和一定的机械加工性 ,而且成本较低 。
The baffle is damageable key part in the stainless steel pipe rolling mill,and bears the shock,rub and press of bilet under 1 100℃～1 200℃ over a long period of time and is washed by cool water periodic.In order to replace the expensive high temperature alloy material,one kind of materiral is developd to be similar with RTCr 34,and adds Ni,Ti,Re and Al to the high chromium cast iron,to rais its synethetical property by stitable heat treatment technology.The results show that this kind of high chromium cast iron possesses good abrasive resistance under high temperature,enough strength and toughness and definite machinability,and the cost is lower,and is easier to melt.
