The present invention provides a furnace having a shape that is movable to approach and move away from the arc furnace through an opening provided in front of the furnace in an enclosure wall that surrounds the arc furnace, and whose central portion protrudes into the interior of the enclosure. It has a configuration in which a front door is provided, and a small door that can be opened and closed is provided on the protrusion of the front door into the enclosure.

When performing slag discharge, oxygen cutting of scrap, temperature measurement of molten steel, sampling, etc., the opening of the enclosure is shielded by the furnace front door, and the small door is opened to perform the work from the outside. Furthermore, during furnace repair work that is carried out after tapping steel and before the next operation, the furnace door is moved away from the enclosure and the opening of the enclosure is opened.
以下、本考案の実施例を添付図面に基いて説明

設されている。 1 and 2 show an embodiment of the present invention. On the foundation on which the enclosure 2 is installed, there is a rail 4 extending from just in front of the working opening 1a of the arc furnace 1 through the opening 2a to the outside of the enclosure 2. A furnace front door 5 is disposed on the rail 4 so that it can run on the rail 4 via wheels 6 and move toward and away from the arc furnace 1.

に支障のない大きさとする。 The planar shape of the furnace front door 5 is as shown in FIG.
The central portion is shaped to protrude toward the inside of the enclosure 2, that is, toward the working opening 1a of the arc furnace 1, and a small door 7, for example, double-opening type, is attached to the protruding portion. The size of the opening of the small door 7 is set to a size that does not hinder various operations such as oxygen cutting, temperature measurement, and sampling.
