Description
TECHNICAL FIELD
[0001] The utility model belongs to smelting equipment technical field, namely a combination module type center cover plate. BACKGROUND
[0002] In the prior art, the electric arc furnace or resistance furnace is an important industrial equipment for high-temperature smelting and heating process, and is widely used in the fields of metallurgy, chemical industry, etc. As one of the key components of the electric arc furnace, the center cover plate becomes an indispensable part in the smelting process due to its excellent high-temperature resistance, sealing, and corrosion resistance performance indicators. Especially in the production of alternating current electric arc furnaces, the center cover plate is usually made of materials with good corrosion resistance and significant magnetic shielding effect due to the presence of strong electromagnetic effects. With the change of market demand, sometimes the same electric arc furnace needs to be used to smelt different products, which puts forward new requirements for the electrode diameter and the pole core circle. Traditionally, in order to meet these new requirements, the usual practice is to disassemble the original center cover plate and reprocess a new center cover plate. This method not only takes a long time and costs a lot, but also because of the deformation of the original equipment during long-term use, the center cover plate made according to the original design often cannot be successfully installed back to the original position, and additional adjustment work needs to be done on site. In this way, the center cover plate modification work not only has high cost and great difficulty in production, but also the quality and service life of the overall equipment are difficult to meet the design standards. SUMMARY
[0003] The utility model aims at the above-mentioned insufficient and provides a combination module type center cover plate with reasonable structure, which can adapt to the change of electrode diameter and pole core circle diameter.
[0004] The technical solution of the utility model is: a combination module type center cover plate is divided into three center water cooling fan blades, each center water cooling fan blade has a water cooling small cover plate passing through the electrode and the electrode sealing device. The center water cooling fan blade has a long strip-shaped water cooling small cover plate mounting hole, and the corresponding water cooling small cover plate is also long strip-shaped; the electrode and the electrode hole of the water cooling small cover plate have an electrode sealing device; the gap between the water cooling small cover plate and the center water cooling fan blade is sealed and connected by a soft high-temperature resistant material.
[0005] In the above-mentioned scheme, it further includes:
[0006] The two ends of the water cooling small cover plate mounting hole are semicircular.
[0007] The center water cooling fan blade is a water jacket structure.
[0008] The utility model discloses a centre cover plate of electrode, which comprises a centre water cooling fan piece and a plurality of water cooling small cover plates arranged on the centre water cooling fan piece.
