Description

one

The invention -OTHOCHrcH to the field of ferrous metallurgy, in particular to the elements of the open-hearth steel-smelting furnace.

The front wall of the open-hearth furnace is known, consisting of vertical frame racks, frames of full-length windows, refractory lining and box-shaped cooled elements in front of the racks.

However, such a wall has insufficient durability of the lining and the metal frame posts.

In order to increase the service life of the metal frame of the furnace, it is proposed to perform the cooled elements in the form of panels made of pipes with a relief surface that are set vertically close to each other, and placed between the windows and on the racks directly facing the working surface (space.

FIG. 1 shows part of the proposed front wall from the side of the working space of the nechi; in fig. 2 - the same, top view.

The wall consists of vertical posts 1, frames of latched windows 2, cooled thick-walled pipes 3 with a relief surface assembled into a panel. The pipes of the panel are installed vertically close to each other and are combined by common collectors 4 for the supply and removal of the cooling medium. The panels are installed in the walls between the windows and close to its frame from the inside and are attached to the racks. The installed panel completely covers the frame of the front wall from the side of the firing space. Refractory coating can be pre-applied to the relief surface of the pipes, which helps to reduce heat loss.

The proposed wall makes it possible to eliminate the deformation of the cure of the lecium as a result of excessive heating and burning.
