Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
89 words
A method of degasification and removal of deleterious inclusions and impurities during electroslag remelting of consumable electrodes wherein at least one consumable electrode is melted by means of an electric current between said electrode and liquid slag and metal contained in a vessel, the improvement comprising blowing agents which improve the quality of the resultant ingot into the liquid slag and metal during the remelting process, the flow of said agents being so directed as to cause a rotation throughout the complete volume of the liquid slag and metal.
Claim 2
Independent Claim
89 words
A method of degasification and removal of deleterious inclusions and impurities during electroslag remelting of consumable electrodes wherein at least one consumable electrode is melted by means of an electric current between said electrode and liquid slag and metal contained in a vessel, the improvement comprising blowing agents which improve the quality of the resultant ingot into the liquid slag and metal during the remelting process, the flow of said agents being so directed as to cause a rotation throughout the complete volume of the liquid slag and metal.
Claim 3
Dependent Claim
22 words
The method as claimed in claim 1, in which said agents are blown into the liquid metal and slag in opposite directions.
Claim 4
Dependent Claim
57 words
The method as claimed in claim 2, in which said agents are blown into the liquid slag under a pressure which is lower than the pressure of said agents blown into the liquid metal by a factor equal to the difference between the specific gravity of the liquid metal and the specific gravity of the liquid slag.
Claim 5
Dependent Claim
42 words
The method as claimed in claim 1, in which there are created in the bath of said liquid slag and metal several zones of rotation in a horizontal plane by blowing said agents into adjacent portions of said bath in opposite directions.
Claim 6
Dependent Claim
22 words
A method as claimed in claim 1, in which said agents are blown into the liquid slag directly under said consumable electrode.
