Embodiment Construction

[0006] Hereinafter, exemplary embodiments according to the present invention will be described in detail.

[0007] The invention provides a method for processing dead-angle slag iron in a tapping plant, which mainly realizes the treatment of dead-angle slag iron by setting a cantilever crane on a crane in front of the furnace.

[0008] In the present invention, the dead corner of the slag iron refers to the location where it is difficult to handle the slag iron by using the method of the prior art, such as using the crane hook in front of the furnace.

[0009] The three tap holes of the blast furnace are evenly distributed around the blast furnace with an included angle of 120°, and each tap hole is provided with its own independent slag iron trough, and the slope of the slag iron trough is 7%. The cantilever crane can reach the dead angle position where the slag iron is stored by lifting, rotating and shrinking up and down, so as to realize the treatment of the slag iron at the dead...

Abstract

The invention discloses a method for treating iron slag at dead angles of an iron plant. In the method, a stokehold crane is provided with a suspension crane and the suspension crane is used for treating the iron slag at the dead angles. The method has the advantages of solving the problem of difficult treatment of the iron slag at the dead angles well, ensuring normal iron discharge of a blast furnace, greatly reducing labor intensity in the stokehold of the blast furnace and improving working conditions of workers and labor efficiency.

Description

Technical field [0001] The invention relates to a method for processing slag iron, in particular to a method for processing slag iron in dead corners of a tapping plant. Background technique [0002] The tapping yard is the place where the slagging and tapping of the blast furnace takes place, and the tapping process is an important part of the blast furnace production. The amount of slag produced in the ironmaking process of Panzhihua vanadium-titanium magnetite is greater than that of ordinary iron ore blast furnace ironmaking, and the viscosity of the slag is relatively large, which brings great difficulty to the iron slag processing work in the iron field. Because the temperature of the slag iron that needs to be processed at the tapping site is still relatively high, the manual processing work environment is harsh. At present, the slag and iron treatment in the casting yard is mainly through manual cleaning of the crane hook installed in the furnace in front of the casting ...
