    专利说明:

    The invention relates to metallurgy, in particular to rollers designed to provide loading and unloading of metallurgical products moving inside a heat treatment furnace.
    The purpose of the invention is to increase the service life by reducing the thermomechanical voltage and heat loss.
    Figure 1 shows schematically a roller, a front view, a partial vertical section; 2 shows a part of a roller for loading and unloading; Fig. 3 shows the welding fastening pattern of the cross member forming the roller disk, the section; figure 4 - roller option; figure 5 is the same vertical section; figure 6 is the same, the cut diametral plane; 7 - the same, side view; f.ig.8 - roller (Fig.7), the incision diametral plane,
    The roller (Fig. 1) for loading-unloading metallurgical products moving inside the furnace operates as follows.
    The metallurgical product may, for example, be formed by a slab or strip moving continuously inside the furnace in which it rests on rollers for loading and unloading. Each roller is formed by a central tube cooled by preferred water, a plurality of discs 2 perpendicular to the axis of tube 1 are supported on the tube, each of these discs 2 being made with a running surface 3 in contact with the product 4. The discs 2 are separated by thermal insulation material 5, designed to reduce heat losses at the level of pipe 1 and discs 2.
    Each disk 2 (FIG. 2) includes through channels 6 along the circumference and through transverse channels 7 and 8. The fastening of the running surface 3 on each of the disks is provided by welding 9.
    The mounting of each disk 2 on the pipe 1 can be provided by the legs 10, which are welded to the pipe 1 and transfer simultaneously the load and the heat flux,

    than these legs provide some flexibility in mounting each disk on the pipe 1, while providing radial thermal expansion of the disk without a large increase in stresses in pipe 1 and the disk. These legs can be on one side or on both sides of the disk.
    The paws 10 provide, simultaneously with the transfer of the load, the flexibility of mounting the disk-pipe and controlling heat losses, and the temperature distribution of the disk, depending on the length of the section of the foot. The through channels 7 and 8 of each disk reduce the stresses, in particular across the crossbar, which are subject to a high thermal gradient. Radial slots can be made to prevent stress in the disk.
    eleven.
    To compensate for the thermal expansion of the running surface, it can be made with gaps 12 evenly distributed around the inner circumference.
    Each of the disks 13 (Fig. 4), supported by the water-cooled pipe 1, includes through channels and radial slots 14, which extend onto the outer running surface of the disk. The discs 13 are separated by heat insulating material 5, which reduces heat losses at the level of pipe 1 and discs 13, and this heat insulating material can be covered with refractory strip material 15. Each of the discs 16 (Figures 5 and 6) mounted on a water-cooled pipe 1 is formed by a monoblock system provided with slots 17, with each disk being attached to the pipe by means of a foot 18 welded to the outer surface of the pipe.
    The roller shown in FIGS. 7 and 8 is designed to transfer thin slabs, the disk 19 is monoblock and includes on one side the through channels 7 and 8 in the disk 19, the disks or cross-pieces that form them can be made of special alloys .
    The roller limits the heat flow between the product being moved and the central pipe 1 cooled by water, and the geometry of the disks is calculated so as to limit the thermomechanical stresses on one side and the heat losses on the other.
