Description

Coil stabilizing device and induction furnace

Technical Field

The utility model relates to an induction coil heating technical field particularly, relates to a coil stabilising arrangement and induction furnace.

Background

In many material developments and productions, a coil is required for induction heating. However, under some frequencies and environments, the coil may vibrate, and due to thermal stress caused by temperature change, coil deformation or other collisions during production easily cause the coil to deviate from the original position during or after production, so that the heating effect deviates from the original design, thereby causing adverse effects on testing and production.

For this reason, the industry generally uses methods of fixing the coil legs, providing vertical fixing rods or rings, and stabilizing the coil by pushing it from both sides with a horizontal rigid rod.

According to the method for fixing the coil leg, when the coil leg is long, even if the bottom of the coil leg is fixed, the upper part still has obvious deviation caused by inclination or slight deformation of the coil leg, so that the actual fixing effect on the coil part above the coil leg is poor.

The method for arranging the vertical fixing rod is that a vertical rod piece with the bottom fixed is additionally arranged on a plane on which coil feet stand, and the position of the rod piece is just attached to the outer edge of the coil, or an annular fixing ring is arranged outside the coil. However, similar problems exist with the method of fixing the coil leg, that is, when the coil leg is long and the coil position is high, the slight deformation and deflection of the rod member will bring about a significant deviation, and the stabilizing effect is not good. Moreover, this puts high demands on the rigidity and toughness of the rod, and it is often difficult to find a suitable material. For the fixed ring, the coil is wrapped, so that the heat dissipation of the coil is prone to be problematic. In addition, the bottom of the fixing rod is fixed in a common welding or punching mode, the method belongs to permanent modification, and the bottom of a hearth is easily damaged for many times, so that when coils with other diameters need to be replaced, the modification cost is high, or the modification cannot be carried out at all. Moreover, the method often needs to additionally install a connecting binding structure between the coil and the fixed rod, and the coil is modified. These all make the method cumbersome and poorly adaptable.

When a transverse rigid rod stabilizing method is used, for example, a corundum rod, two ends of the rigid rod are respectively propped against a furnace wall and a coil to directly fix the coil, and the coil position and the forced jacking of the two ends of the rigid rod are ensured during fixing, and the rigid rod is prevented from sliding down, so that the operation is very difficult during fixing. Moreover, the rigid member is difficult to cope with due to deformation and cracking of the rigid member in long-term high-temperature use or frequent short-distance fine adjustment of the coil position in production. And because the rod is suspended, once the force for tightly pushing the two ends is insufficient, the rod can slide off, and the operation is difficult during installation. In addition, the rigid rod can only be propped against one turn of the coil, so that the turn of the coil is easy to deform alone after long-term use.

The adjustment screw 500 is metal, typically stainless steel, but is already located away from the coil 100, in close proximity to the furnace 200 wall, so the induction is weak and within acceptable limits. The threaded holes 520 are metal, typically stainless steel, and are fixed within the furnace wall top block 300.

The coil top piece 400 can be made as multiple pieces of different thicknesses to be replaced to accommodate the large variations in size or position of the coil 100 beyond the adjustment range of the adjustment screw 500 on the furnace wall top piece 300. The thickness of the coil top piece 400 is the distance between the contact surface of the coil top piece 400 and the coil 100 to the contact surface of the coil top piece 400 and the furnace wall top piece 300. "thickness" refers to the dimension along the diameter of the furnace.

In order to realize the adjustment function to adapt to the hearths 200 and the coils 100 with different sizes and meet the fine adjustment function frequently required in use, the distance adjustment in the thickness direction is realized by replacing the coil top block 400, and the distance adjustment is realized by the adjustment mechanism on the furnace wall top block 300.

When the coil 100 is replaced or the position is adjusted, so that the distance between the edge of the coil 100 and the inner wall of the hearth 200 in the thickness direction needs to be adjusted to be larger than 10mm, the coil top block 400 with a proper size is replaced. When the adjustment amount is small, generally within 10mm, for example, after the coil top block 400 is replaced, fine adjustment is needed, the adjusting screw 500 in the screw hole 520 is screwed through the adjusting hole 510 of the furnace wall top block 300, and the distance between the furnace wall top block 300 and the inner wall of the furnace 200 is adjusted, so that small adjustment of the distance between the coil 100 and the inner wall of the furnace 200 is realized.

The furnace wall top block 300 and the coil top block 400 are made of non-metallic materials with certain high-temperature resistance, such as resin and polytetrafluoroethylene, so that induction is avoided.

Specifically, the 600mm inside diameter furnace, the 300mm outside diameter coil 100, the furnace wall crown block 300 and the coil crown block 400 have a transverse dimension of about 150mm and a width generally in the range of 20-40 mm.

Referring to fig. 1, in the present embodiment, the top of the coil top block 400 is provided with an inner boss 421 and an outer boss 420 in opposing positions, the outer boss 420 for supporting on the top of the furnace wall top block 300 and the inner boss 421 for supporting on the top of the coil 100 to collectively prevent the coil top block 400 from falling.

A plurality of replaceable coil headers 400 of different transverse thickness dimensions are sandwiched between the coil 100 and the furnace wall header 300. The inner boss 421 and the outer boss 420 are formed at two sides of the top of the coil top block 400 in a protruding manner, and can be hung on the coil 100 and the furnace wall top block 300 without sliding off.

That is, in the case where the bottom of the coil top block 400 is located low, the support 600 may be used to support the bottom of the coil top block 400. The preset height is set according to actual conditions and is a lower height.

The coil top piece 400 can be designed as a support structure on the lower part or directly stand on the bottom of the furnace 200 to avoid slipping off, and the furnace wall top piece 300 can also be designed with legs, supports, hooks, etc. to avoid slipping off. The lower portion of the furnace wall top piece 300 may also be directly above the plane in which the legs of the coil 100 lie, such as the bottom of the furnace chamber 200, for ease of installation adjustment.

Referring to FIG. 1, in this embodiment, the furnace wall top piece 300 is integrally formed with the coil top piece 400. The furnace wall top piece 300 and the coil top piece 400 may be designed in one piece, but there must be one side butting against the coil 100 and the other side butting against the furnace wall for stabilization. In other embodiments, the furnace wall top piece 300 and the coil top piece 400 may also be manufactured separately.

According to the coil stabilizing device 10 provided by the embodiment, the implementation process is as follows:

When the coil 100 having an outer diameter of 240mm is used, the coil top block 400 having a height of 110mm, a width of 40mm and a thickness of 125mm is used, and a 10 mm-high portion on both sides of the tip end of the coil top block 400 protrudes to both sides by 20mm to form the outer boss 420 and the inner boss 421, and the coil 100 and the upper end of the furnace wall top block 300 are lapped in this structure.

When the 320mm outer diameter coil 100 is used, the coil top block 400 having a height of 110mm, a width of 40mm and a thickness of 85mm is used. When the coil 100 having an outer diameter of 480mm is used, the coil top block 400 is not used, and the furnace wall top block 300 is directly abutted against the coil 100 from the coil 100 side, thereby performing a stabilizing function.

The coil 100 is protected. Because the coil top block 400 is in integral contact with the side surface of the coil 100, the stress is uniform, and the condition that a certain turn in the coil 100 is concentrated by the top stress and is deformed greatly is avoided.

The installation operation is convenient, and because the problem of slipping does not exist, only the adjusting screw 500 needs to be rotated after the coil top block 400 with a proper size is installed during installation. Thus, the problems of difficult installation and slipping of the rigid rod by a side stabilizing method are avoided.

The hearth 200 and the coil 100 do not need to be modified, the hearth 200 is not damaged, the installation cost is avoided, and the manufacturing cost is low.
