选矿分级机轴由于轴尾部在矿物水中,经长期生产使用后,经过水中矿石颗粒对分级轴尾部磨损磨薄,使分级轴尾部距离分级轴上法兰根部100mm至200mm处被磨断,分级轴上尾部法兰与分级轴分开,使分级机不能正常运转,影响生产。为了节约成本在现场重新修复使用。因现场水、油污、空气湿度大等多种因素的影响,容易产生各种焊接缺陷,焊接接头缺陷的存在直接危及整个分级轴的强度,为了保证焊接后达到分级轴运转强度,因此将焊接接头缺陷控制在允许范围内,达到使用强度。需要制定相应的控制措施及合理的焊接工艺。
Beneficiation grading shaft As the shaft tail in mineral water, after long-term production and use, through the water ore particles on the grading shaft tail wear thinner, the grading shaft tail from the grading shaft flange root 100mm to 200mm Department was broken, graded shaft The upper tail flange is separated from the staging shaft so that the classifier can not operate normally and affect the production. In order to save costs in the field to re-use. Due to the influence of many factors such as water, oil and air humidity in the scene, various welding defects are apt to occur. The existence of welding joint defects directly endangers the strength of the entire classification shaft. In order to ensure the operation strength of the classification shaft after welding, Defect control within the allowable range, to use strength. The need to develop appropriate control measures and reasonable welding process.
