High Pressure Grinding Rolls studs

- Raise the left and right frames on both sides of the extrusion roll of the high-pressure grinding roll symmetrically with the left and right sleepers to ensure sufficient height for the extrusion roll to operate without damaging the mechanical assembly joint surface under the frame; - Rotate the position on the shaft shoulder on one side of the extrusion roll where the stud needs to be replaced to the horizontal position. Use the magnetic drill fixed on the left frame to drill a stud hole at this position by operating the handle with a drill bit; - Then aim the fixed long baking gun at the stud hole for heating from the inside to the outside. When the stud hole and the surrounding area are heated to a red-hot surface close to the oxidized state, apply qj102 silver brazing flux and inlay the matching stud into the stud hole so that the surface height of the stud is equal to the height of the existing used stud;
