[0027] The present invention will be further explained below in conjunction with the drawings;
[0028] The cylinder liner in the semi-automatic mill includes a lower part of a lifting bar 1, a lifting bar 2, and an upper part 3 of the lifting bar. The feature is that the lifting bar 2 is arranged in the center of the cylinder liner 6, and the upper part 3 of the lifting bar is set at a right angle. To facilitate lifting of the steel ball, the lower part 1 of the lifting bar is set at an obtuse angle, and reinforcing ribs 4 are symmetrically and uniformly arranged on the upper part 3 of the lifting bar and the lower part 1 of the lifting bar, and lifting holes 5 are provided on the ribs of the reinforcing rib 4.
[0029] The processing method of the cylinder liner in the semi-automatic mill is characterized by: adopting ultra-high manganese alloy steel; the elements of the formula are in weight percentage, carbon: 1.0~1.4, manganese: 17~19, phosphorus: <0.05, Silicon: 0.3~1.0, S:...
