Abstract

The invention provides an electrode for LF (ladle furnace) refining furnaces, which comprises an electrode body and an electrode contact connected with the electrode body through screws, wherein the electrode contact is a shuttle-shaped revolving body; the outer side surface of the electrode contact is provided with a connecting thread; one end of the electrode body is provided with a contact hole matched with the electrode contact; and the inner side surface of the contact hole is provided with an internal thread. After adopting the structure, the two adjacent electrode bodies can be conveniently connected together through the electrode contact, and the thread connection structure is convenient to disassemble and assemble and easy to implement. The maximal internal diameter of the contact hole is D which ranges from 270nm to 276nm, the diameter of one end of the electrode contact is d1 which ranges from 260nm to 268nm, the diameter of the other end is d2 which ranges from 195nm to 200nm, and the length of the electrode contact is L which ranges from 350nm to 360nm. The structural form effectively enhances the breaking resistance of the electrode contact, and prolongs the service life of the electrode contact.

Description

technical field

[0001] The invention relates to an LF refining furnace, in particular to an electrode for the LF refining furnace. Background technique

[0002] LF refining furnace is the necessary refining equipment for the current steel industry to enhance its own industry competitiveness and smelt high value-added products. It is also the necessary production equipment for all steel mills to coordinate production rhythm and save accidents. It has become the mainstream refining configuration of major steel mills. . However, with the rapid development of LF refining furnace technology, some defects of LF refining furnace itself are gradually exposed, and with the different operating conditions of each steel plant, the problems exposed by LF ladle refining furnace are also different. The most common It is the problem of electrode breakage, especially the problem of electrode joint breakage. Since the electrode joint bears the largest force, the electrode joint is the weak l...
