Description

Technical Field

[0001] The utility model relates to an electrode system of a submerged arc furnace, in particular to a copper tile with a boss. Background Art

[0002] Copper tiles are important conductive components of the electrode system of the submerged arc furnace. Their main function is to transmit three-phase electrode current. The basic structure of copper tiles is a thick arc copper plate with cooling channels inside.

[0032] Example 2

[0033] The difference between the copper tile with boss in this embodiment and that in embodiment 1 is as follows:

[0034] The boss cooling section 32 is composed of a plurality of channel sections, each of which is connected end to end in sequence to form the boss cooling section 32.

On this basis, the ends or the middle of certain channel sections can also be blocked by waterway plugs to form the required boss cooling section 32, so that the cooling fluid can flow in the direction required by the design.

[0035] Example 3

[0036] like Figure 6-7 As shown, the difference between the copper tile with bosses in this embodiment and that in embodiment 1 is as follows:

The notch of the left water groove 21 opens on the left side of the boss 2, and the notch of the right water groove 21 opens on the right side of the boss 2. The notches of each water groove 21 are respectively installed with a water groove cover plate 22, and the water groove cover plate 22 covers and welds the notches of the water groove 21. The boss cooling section 32 includes an arc-shaped channel section 321 and two U-shaped channel sections 324. The arc-shaped channel section 321 extends in the left-right direction and is parallel to the outer arc surface of the boss 2.

Above the left and right ends of the channel section 321, the opening of one U-shaped channel section 324 is set to the left, and the opening of the other U-shaped channel section 324 is set to the right. The lower end of the water inlet section 31 is connected with one end of the U-shaped channel section 324 on the left, and the other end of the U-shaped channel section 324 on the left is connected with the left end of the arc-shaped channel section 321 through the water groove 21 on the left, and the right end of the arc-shaped channel section 321 is connected with one end of the U-shaped channel section 324 on the right through the water groove 21 on the right, and the other end of the U-shaped channel section 324 on the right is connected with the lower end of the water outlet section 33. Conventional or unconventional machining methods such as drilling, boring, and milling can be used to machine water grooves 21 on the left and right sides of the boss 2, and then the water groove cover plate 22 is used to cover and weld the corresponding notch of the water groove 21. On this basis, the ends or middle parts of certain channel sections are blocked with water channel plugs, so that a reciprocating and winding boss cooling section 32 is formed inside the boss 2, which can have a good cooling effect on the bottom of the copper tile and greatly extend the service life of the copper tile.

[0038] The U-shaped channel section 324 includes an inner channel 36, a transverse channel 322 and an outer channel 323 which are connected in sequence from end to end. The inner channel 36 and the outer channel 323 extend horizontally in the left-right direction and are arranged inside and outside. The transverse channel 322 extends horizontally in the inside-outside direction. The lower end of the water inlet section 31 is connected with the left end of the inner channel 36 on the left side. The left end of the outer channel 323 on the left side is connected with the left end of the arc channel section 321 through the water groove 21 on the left side. The right end of the arc channel section 321 is connected with the right end of the outer channel 323 on the right side through the water groove 21 on the right side. The right end of the inner channel 36 on the right side is connected with the lower end of the water outlet section 33.
