辉绿岩是理想石辊材料,能克服花岗岩石辊有时夹杂长石的弊端。其价格比铸钢辊和不锈钢辊低,耐酸碱、生产纸质高的优点、得到广泛应用。由惠安县辉绿岩厂与福建省造纸工业公司研究所的协作联合研制,于1992年通过省级鉴定并获得福建省优秀产品三等奖。辉绿岩石辊改变石辊端面的传统阶梯结合为单斜面结合,轴端面受力面积可达80～85％,比传统设计增加1.1～1.6倍,使辊体和轴结合更紧密、合理有效地解决石辊运行中易松、易爆、易裂等弊端。产品技术指标:同心度<0.03、锥度<0.06/1000、椭圆度<0.015、辊面光洁度>(?)1.6。可代替铸铁
The diabase is an ideal stone roller material that can overcome the disadvantages of granite stone rollers that are sometimes mixed with feldspar. Its price is lower than that of cast steel rolls and stainless steel rolls, and it is widely used due to its advantages of acid and alkali resistance and high paper production. It was jointly developed by the cooperation of Hui’an County Huiqingyan Factory and Fujian Provincial Paper Industry Research Institute. In 1992, it passed the provincial appraisal and won the third prize of Fujian Provincial Outstanding Product. The traditional step combination of the diabase rock roller changing the end face of the stone roller is a combination of single inclined planes, and the force area of the axial end face can reach 80-85%, which is 1.1-1.6 times more than the traditional design, so that the roller body and the shaft can be combined tightly and effectively. Solve the stone roll operation easy to loose, explosive, easy to crack and other defects.
