に複数基を平行に設置する場合が多い。2. Description of the Related Art Steel pieces such as slabs which have conventionally been required to be heated at a high temperature are often induction-heated by using a lower charging type heating furnace. Since this lower charging type heating furnace heats the steel pieces one by one, a plurality of bases are often installed in parallel so that the charged steel pieces are parallel to each other.

ッグに集積するようにしていた。When a plurality of lower-loading type heating furnaces are installed in this way, a carriage that travels at right angles to the longitudinal direction of the steel pieces is installed under the furnace to carry the steel pieces into and out of a predetermined heating furnace. To do.
Then, it is general that the steel pieces are placed on the elevating table installed for each heating furnace, charged and extracted. When multiple lower-loading type heating furnaces were installed, the slag and scale (hereinafter collectively referred to as slag) generated in the heating furnace were accumulated for a certain period of time, and then the heating furnace was stopped and the heating furnace was cooled. It was designed to be collectively discharged by a rear person and accumulated in a Noro bag by a portable conveyor or the like.

稼動率が低下するので操業上問題が生じる。In the lower charging type heating furnace, in particular, the steel slab is heated at a high temperature, so that the slag is severely generated. In addition, since it is a bottom-loading type, there are various facilities under the furnace, and it is difficult to install a permanent slag discharge facility. Further, manual roasting is not easy because the environment is bad and high heat work is required, and it is necessary to stop and cool the heating furnace, which lowers the basic unit of the heating furnace and lowers the operating rate, causing operational problems. Occurs.

備を提供することを目的とする。The one disclosed in Japanese Utility Model Laid-Open No. 56-94497 is as follows.
A slag discharge groove inclined toward the outside of the furnace is provided in the hearth to discharge the slag to a sack on the trolley, but the lower loading type heating furnace does not have a slope enough to allow the slag to flow.
Further, even if the roe is scraped out from the inside of the furnace as in Japanese Utility Model Laid-Open No. 57-150799, the subsequent treatment is difficult. The present invention solves the above-mentioned problems and can remove the slag generated in the lower charging type heating furnace to the outside of the heating furnace at any time, and can automatically accumulate it in the sack bag outside the furnace, which does not require any manpower. The purpose is to provide equipment.
