Researching the Influence of the Location Tool on the Treatment of Large Shafts Requiring Surface Shaping

摘要

Rotary kilns for clinker production furnaces have lengths of up to 220 m and sleeve diameters of 6 m. The metal shell is up to 80 mm thick at the dress rings that transmit their mass on oven support rollers. Due to temperature variations (precipitation lining) shells can become deformed and the bent rotational axis of the furnace can resulting in a ring becoming trapped in this zone. In addition to rotating about its axis of rotation there is also movement in the plane of rotation, something that depends on the curvature of the axis of the furnace. This movement leads to the fact that the ring is not always situated on two rollers. Therefore, the side machine tool module, that is mounted on the imaginary axis of rotation of the furnace and is in connection with the ring is not always in contact with the cutting tool. Mathematical modeling of the processing is necessary to find the dependence of the ring.
