    Prior to the receipt of a charge of molten metal, a ladle is heated by a direct flame, by applying a seal to the rim of the ladle and directing air through a heat exchanger and to the ladle, mixing fuel with the air and igniting the mixture and directing the flame in to the ladle chamber, and exhausting the gases of combustion from the ladle chamber back through the heat exchanger. The seal applied to the rim of the ladle comprises a network of refractory fiber modules mounted in a common plane. Each module comprises a rectangular block formed of a web of refractory fibers in an accordion folded arrangement, and the modules are mounted with their folded edges exposed, and with the folds of each module extending at right angles with respect to the folds of the adjacent modules.

    .. The device (1) of claim 1, which means that the pipeline is for removal of exhaust gases And the engine consists of two sections that are angled to each other, while the section passes through blocks of refractory material, and in the second there is a heat exchanger.
    3. A device according to claim 1, wherein the fabric is made from C) 1 in each block; the refractory fibrous material is arranged in zigzag parallel layers.
    one
    The invention relates to metallurgy P1, more specifically to the design of devices for heating tanks, mainly casting ladles.
    The purpose of the invention is to create a reliable seal on the edges of buckets of various sizes.
    Pa figs. 1 given a device for heating buckets, general view; in FIG. 2 a ladle heater without a carriage, vd rear; in fig. 3 - ladle heater without a trolley, side view; in fig. 4 sealing element; in fig. 5 blocks of heating element and part of its metal frame.
    The device for heating the buckets contains a blower 1, burners 2, directed inward of the koshi 3, pipeline 4 for supplying gas and pipeline 5 for discharging exhaust gases, heat exchanger 6 and sealing element 7 of the bucket edge, made in the form of a metal frame 8 lined with layer 9 refractory compressible fibrous material.
    The device is also equipped with a trolley 10 with an engine, where all the nodes of the device are located. At the entrance to the car, the blower is equipped with a filter 11. The bucket 3 is located on its side on the support blocks 12. The pipeline 5 for lining exhaust gases is lined, consists of two sections angled to each other, in the second section of it there is a heat exchanger 6 at the outlet of which is installed flap. The sealing element 7 of the bucket edge 3 consists of a metallic frame 8, futtered with a layer 9 of refractory compressible fibrous material. In the form of blocks 13 mounted on a metal frame 8. Each (bii block 13. formed from a web
    refractory fibers rolled up in zigzag parallel layers and has a cubic shape. Each unit has support rods 14 with connecting lugs 1 for fastening it on the bracket 16 of a metal frame 8. In the sealing element 7, there are holes 17 for burners and an opening 18 for a pipeline 5 for exhaust gas removal. The heat exchanger 6 is made of ceramic material and is not exposed to direct heat radiation from the flame of the burners 2.
    Operation: for heating the buckets as follows.
    The carriage 10 together with the device runs over the bucket 3, located on its side on the blinker 12, the blocks 13 of the sealing element 7 are pressed tightly against the edges of the bucket and form a reliable seal. In addition, the remaining units reliably protect other device nodes from the burner flame. Due to the fact that the blocks 13 can compress in the presence of chipping at the edge of the bucket or splashes of metal, they provide a seal around the entire perimeter of the bucket. The supply lines 4 to the burners 2 are supplied with fuel that burns and the air from the blower 1, so that the buckets 3 are heated and dried. Exhaust gases through the pipeline 5 are removed from the cavity of the bucket 3, pass through the heat exchanger 6 and further. After the end of heating and drying the bucket, close the valve, retract the trolley 10 with the device and turn the bucket into a vertical position.
    By making the sealing element in the form of blocks of compressible refractory material, the bucket edge is sealed reliably.
