Problems solved by technology

[0013] However, these solutions may not ensure complete cleaning and unclogging of tunnels and slag doors, making further cleaning interventions necessary
[0014] Also, known solutions are often difficult to install or remove from the melting furnace and may have a volume that hinders the operations of deslagging, insertion of additive material and sampling
[0015] Another disadvantage of the known solution is that the cleaning element, which is in the inoperative position when the door is open, tends to place itself in a large part of the bore of the furnace, with the consequence that it may be contaminated by the discharged slag, thus requiring further cleaning.

Abstract

The invention discloses a slag door for a melting furnace. A slag door for a melting furnace (11) for the production of steel is suitable to be associated with an aperture (34) provided in a lateral wall (33) of the melting furnace (11) and to cooperate with a slag channel (13) provided inside the melting furnace (11) itself

Description

technical field [0001] The embodiments described herein relate to a slag door for a melting furnace. [0002] In particular, a slag door according to the invention is used in conjunction with metal melting furnaces to allow selective discharge of at least part of the slag layer produced during the melting process used to produce steel. Background technique [0003] Common metal melting furnaces, for example of the electric arc type, basically consist of a housing for containing molten steel, a covering dome equipped with an openable cover, electrodes descending through the dome and a suction device for the fumes. [0004] Electric arc furnaces typically include a slag door, usually located in the vertical wall of the enclosure, and communicating with the interior of the furnace through a tunnel or slag channel, lined with refractory material (and / or with cooling elements). The slag door is primarily used for extracting the slag, as well as for other activities such as loadi...
