Description

Technical Field

[0002] At present, in order to avoid the pouring port during installation, the non-vacuum induction furnace cover for alloy smelting is generally spliced ​​with two semi-circular panels, and then welded and fixed above the splicing.

[0003] However, this one-sided welding method makes the joints less firm. Under the extrusion force of long-term high-temperature expansion and the gravity of the material, the joints are easily damaged and broken, resulting in the displacement of the two annular plates, which cannot protect the furnace lining. In addition, it is inconvenient to remove and maintain the furnace lining. Therefore, how to ensure that the alloy smelting non-vacuum induction furnace cover can stably and conveniently protect the furnace lining has become a problem that needs to be solved.

[0022] After the first semi-annular panel 1 and the second semi-annular panel 2 are spliced ​​together, a splicing seam 11 and a gap 12 for avoiding material dumping are formed.

[0023] The crimping plate 3 is pressed and fixed on the joint seam 11 , one end of the crimping plate 3 is fixed to the first semi-annular panel 1 by a first bolt 4 , and the other end of the crimping plate 3 is fixed to the second semi-annular panel 2 by a second bolt 5 .

[0024] The third bolt 6 is fixed on the first semi-annular panel 1 after passing through the crimping plate 3 , and the fourth bolt 7 is fixed on the second semi-annular panel 2 after passing through the crimping plate 3 . The third bolt 6 and the fourth bolt 7 are respectively arranged close to the joint seam 11 .

[0025] Optionally, the pressing plate 3 does not exceed the top surface of the first semi-annular panel 1 and the second semi-annular panel 2. Such arrangement of the pressing plate does not affect the feeding of materials at the furnace mouth and saves working space.

[0026] Preferably, the crimping plate 3 is semi-circular, and the inner and outer diameters of the crimping plate 3 are the same as the inner and outer diameters of the first semi-circular panel 1 and the second semi-circular panel 2. This arrangement facilitates the top surface arrangement of the first semi-circular panel and the second semi-circular panel, and can enhance the splicing strength of the two.

[0027] Optionally, the pressing plates 3 are symmetrically pressed on both sides of the joint seam 11. This arrangement facilitates evenly pressing the first semi-annular panel and the second semi-annular panel.

[0028] Optionally, the crimping plate 3 completely covers the joint seam 11. In this way, the joint between the first semi-annular panel and the second semi-annular panel is more firmly formed.

[0029] Optionally, the threaded parts of the first bolt 4 and the third bolt 6 are directly screwed and fixed in the first semi-annular panel 1, and the threaded parts of the second bolt 5 and the fourth bolt 7 are directly screwed and fixed in the second semi-annular panel 2. This arrangement eliminates the need for nuts and makes fixation more convenient.

[0030] Optionally, the first bolt 4 and the second bolt 5 are symmetrically arranged on both sides of the joint 11. This arrangement facilitates balanced pressing of the first semi-annular panel and the second semi-annular panel.

[0031] Optionally, the third bolt 6 and the fourth bolt 7 are symmetrically arranged on both sides of the joint 11. Preferably, the center line of the third bolt 6 and the fourth bolt 7 passes through the center of the joint 11. This arrangement facilitates the pressing plate to press the joint evenly.

[0032] Optionally, the first bolt 4, the second bolt 5, the third bolt 6 and the fourth bolt 7 are of the same size, which facilitates the purchase and maintenance of the bolts.

[0033] The alloy smelting non-vacuum induction furnace cover of the utility model has the advantages of stable splicing, not easy deformation, long service life and easy disassembly, which can not only stably protect the furnace lining body but also facilitate maintenance inside the furnace.
