The present applied condition of the heating method and various heaters of extrusion container were introduced, and then the existing problems in heating process of extrusion container were analyzed. It is indicated that uniform stress distribution is used as principle of extrusion container heating, the heater installation should be closed to center of extrusion container in order to decrease temperature difference between jacket and lining, and also proposed that the independent heating system should be adopted in front and rear ends, top and bottom parts of extrusion container so as to control temperature rise and difference by using multi-zone heating components with correct positioning, which can make temperature and stress uniform for extrusion container, and increase the service life of extrusion container.
