Description of the Invention: [Technical Field of the Invention] The present invention relates to a coiler drive for an upper side drive roller and a lower side drive roller for a rolling mill. [Prior Art] This type of reel drive is used in a hot roll mill and a cold roll mill. The lower side drive roller comprises a solid material (for example, a steel material having a wear layer re-installed by welding), and the upper side drive roller is implemented by a steel hollow roller. The hollow roller I has a wear layer that is re-installed by welding. However, C knows that this type of reel drive has {7 disadvantages: the roller has small holes on the surface of the roller cover, causing the indentation to be generated on the rolling material, and the roller wear is thick. The layer has only a small portion of the effective area, and the slats that have been rolled and processed are usually attached to the roller, and the roller body reinstalled by the welding process is used for the private hungry hip. Rolling is done in a very expensive way. SUMMARY OF THE INVENTION The present invention is based on the swaying of a coiler drive that avoids these disadvantages. This item is obtained by means of the roller shaft, a cast iron cover is glued and/or fired into the roller shaft by the lower drive roller. However, this item can also be obtained by this The upper drive roller has a cast iron housing of 1328476 which is then supported between two clamping elements that are placed on a shaft. Due to the use of a cast iron cover, the rollers are lean, and the surface of the scorpion is no longer in contact with the rolling material, so that the surface of the light gas rolling mill is no longer rolled by the drive. The sub-phase is contacted and subjected to grinding and grinding. In addition, the hot rolled slats described above are also less likely to adhere and/or remain on the roller cover. An advantage of the invention is that the cast iron outer cover is on the exterior and has a processing layer. This processing layer can be produced in a cost-effective manner by centrifugal casting to have a sufficient thickness so that the material can have a large wear area and a long service life. If the cast iron cover is made of ductile cast iron and the work layer is made of indefinite eh (1) east coffee, this is a cost-effective cover. A higher hardness 'yes' can also result in a longer service life. If the working layer is made of chrome-plated cast iron or even high-speed steel, even higher hardness and longer service life than in the case of indefinite chilled cast iron can be obtained. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiment is described in detail: Figure i shows a lower side drive roller 1' having a steel roller shaft 2' wherein one of the cast iron outer covers 3 is glued and/or fired to the roll On the child axis. This cast iron cover 3 was produced by centrifugal casting. An abradable processing layer 4 is located at the outer periphery of the cast iron housing 3 1328476. Figure 2 shows an upper driver roller having a roller shaft 2'. A cast iron cover 3 is supported on the roller shaft 2' by the action of two clamping members υ 1 to 3. The outer layer of the cast iron outer cover 3' is composed of a wear-treated layer 4 obtained by a centrifugal casting method. [Simple description of the drawings] This invention will be described in detail based on the accompanying drawings. Figure 1 shows a cross-sectional view through the lower side drive roller, and Figure 2 shows a cross-sectional view through an upper side drive roller.
