Embodiment 1
[0028] refer to Figure 1 to Figure 4 , the present invention includes a furnace cover 12; the furnace cover 12 is plugged with the electrode shield 11 through the jack 13 at its top; the main points are:
[0029] The top of the furnace cover 12 is provided with a sealing ring base 1 corresponding to the aperture of the jack 13, and the outer diameter of the sealing ring base 1 is provided with a support frame 2; The screen 11 corresponds to the sealing ring II6 that fits and plugs in, and the outer diameter of the sealing ring II6 is fixedly connected to the support frame 2; the top of the sealing ring II6 is provided with a sealing brick ring that fits and plugs in correspondingly to the electrode shield 11 4;
[0030] The outer diameter of the sealing brick ring 4 is provided with an insulating box II8, and the outer diameter of the sealing brick ring 4 is elastically connected to the insulating box II8 through a pre-tension spring 7; the insulating box II8 and the support...
Embodiment 2
[0037] A sealing brick ring material, which is prepared according to the following process:
[0038]Add nano-diatomaceous earth, nano-zeolite powder and dibutyl maleate into the stirring tank in turn, and stir while heating. When the temperature reaches 80°C, add tetrabutyl titanate, and continue stirring for 30 minutes under the condition of heat preservation, and then Cool down to 60°C, add polyolefin elastomer, and continue to stir for 60 minutes to obtain modified polyolefin elastomer; wherein, the nano diatomaceous earth, nano zeolite powder, dibutyl maleate, tetrabutyl titanate and poly The mass ratio of olefin elastomer is 10:7:2:3:78;
[0039] Add talcum powder, sodium tripolyphosphate, sodium dodecylsulfonate, phthalate, polyvinyl alcohol and modified polyolefin elastomer in a mass ratio of 1:2:2:5:10:70 Put it into the mixing tank, raise the temperature to 75°C, and stir at 200rpm for 30 minutes; then raise the temperature to 90°C, continue to stir at 200rpm for 15 ...
