Embodiment 1
[0026] Embodiment 1, a kind of preparation method of steel-lined washing roll, its steps are as follows:
[0027] (1) Preparation of steel inner liner roll: choose hot-rolled seamless pipe, and cut it according to the size to form the inner liner shell; then choose 45# steel, and cut it according to the design size to form the left and right shaft head blanks, bulkhead blanks and plugs For the blank, the left and right axle head blanks, bulkhead blanks and plug blanks are respectively rough-turned by a lathe, leaving a 2-3 mm margin for finish turning, and then the turned left and right axle heads are subjected to quenching and tempering treatment and anti-rust treatment, so that The hardness reaches HB235; then the shaft head, plug, and bulkhead are welded into the shaft head assembly; after the inner roller shell is heated at 300-350°C, the shaft head assembly and the inner roller shell are combined and hot-packed in place , after it cools down slowly, the shaft head assembl...
Embodiment 2
[0036] Example 2, in the preparation method of the steel-lined washing roll described in Example 1, when two layers are cross-wound according to ±20°, the tension is 4 N, and when two layers are wound according to 90° hoop, the tension is 8 N. When two layers are cross-wound according to ±32°, the tension is 4 N, when two layers are cross-wound according to ±45°, the tension is 5 N, when two layers are wound according to 90° hoop, the tension is 8 N.
Embodiment 3
[0037] Example 3, in the preparation method of the steel-lined washing roll described in Examples 1 and 2, the rubber roll is vulcanized, and the step of the vulcanization process is to wrap and wrap several layers of cotton cloth or nylon cloth on the outer surface of the rubber roll, and then Fix it with steel wire or fiber rope; then put the rubber roller into a steam vulcanization tank for vulcanization treatment, the vulcanization temperature is 120-150°C, and the vulcanization time is 2-4 hours; Open cotton or nylon cloth and steel wire or fiber rope.
