(54) ПОЛАЯ КРЫШКА ДЛЯ СУШКИ СТАЛЕРАЗЛИВОЧНЫХ И ЧУГУНОВОЗНЫХ КОВШЕЙ(54) POLLING COVER FOR DRYING OF STEEL FILLING AND IRON-TAKING BUCKETS

К кольцевому коллектору 3 присоединен воздухопровод 6, выполненный в видетобразной трубы. Средний отвод 7 этой труОы расположен внутри воздушной распределительной трубы 4, а внутри отвода 7 помещен газопровод 8, образующий вместе с отводом 7 газовую горелку 9. В полости. крышки 1 расположен распределительный лист 10, который при ПОМОШ.И ребер жесткости 11 крепитс к верхней части крышки. В нижней части воздушнойраспределительной трубы выполнены шели 12. Зазор между распределительным листом 10 и нижней частью крышки 1 должен быть таким, чтобы обеспечить максимальное ее охлаждение . В крышке выполнены также трубы 13 дл отвода продуктов сгорани .To the annular manifold 3 is connected to the air pipe 6, made in vidteobrazny pipe. The middle outlet 7 of this pipe is located inside the air distribution pipe 4, and inside the outlet 7 is placed a gas pipeline 8, which together with the outlet 7 forms a gas burner 9. In the cavity. the cover 1 is located distribution sheet 10, which, with a help and stiffeners 11 is attached to the top of the cover. In the lower part of the air distribution pipe, shells 12 are made. The gap between the distribution sheet 10 and the lower part of the cover 1 must be such as to ensure its maximum cooling. The cover is also made of pipe 13 for removal of combustion products.

Воздух от вентил торной установки подаетс по патрубку 5, проходит в воздушную распределительну трубу 4, через шелк 12 попадает в крышку 1, и проход в зазоре между распределительным листом 10 и нижней частью крышки, охлаждает ее. Проход внутри крышки 1, воздух нагреваетс и нагретый попадает через кольцеьей коллектор З.гп-образную трубу в горелку 9, и смешиваетс с газом. Продукты сгорани отвод тс через трубы 13.The air from the fan installation is supplied through the nozzle 5, passes into the air distribution pipe 4, through the silk 12 enters the cover 1, and the passage in the gap between the distribution sheet 10 and the bottom part of the cover cools it. The passage inside the cover 1, the air is heated and the heated collector through the ring collector Z.Gn-shaped tube into the burner 9, and mixed with gas. Combustion products are discharged through pipes 13.

Claims

1. A floor cover for drying steel casting and cast-iron ladles, containing an air line installed in the hole of the cover and a gas pipe with a gas burner, characterized in that it is equipped with an annular collector installed outside the cover and a distribution air pipe with inlet

0 with a nozzle installed in the opening of the lid, with the air duct attached to the annular manifold and made in the form of a 1-shaped pipe, the middle outlet of which is located inside the distribution pipe, and in the cavity of the lid there is a distribution sheet equipped with stiffeners.

2. A cover according to claim 1, characterized in that slots are made in the lower part of the distribution pipe.
