[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0025] like Figure 1 The crucible boiler of the intermediate frequency furnace shown is divided into two parts: the furnace body and the furnace bottom. The furnace body is a cylinder, which needs to be rolled and welded with a 5mm thick rectangular steel plate; the furnace bottom is a cone, which needs to be welded with a cone-shaped steel plate and a circular steel plate. The cone-shaped steel plate needs to be rolled with a 5mm thick fan-shaped circular steel plate; the furnace body and the furnace bottom are welded together to form a complete crucible boiler. The existing plate rolling machine is a universal three-roller plate rolling machine, including a base, a left mounting frame and a right mounting frame fixed on the base, and two active working rollers and a passive working roller installed between the left and right mounting frames. The two active rollers are connected to the driving device, and the passive roller is located directly above the center line of the two active rollers. Both ends of the three working rollers are installed in the corresponding bearing seats, and position adjustment devices are installed respectively. All of them adopt a spiral mechanism to change the position by rotating the spiral rod.

[0026] With respect to the existing plate rolling machine, the utility model proposes the following improvements:

[0027] 1. On the basis of keeping the original two active rollers and their position adjustment devices unchanged and selecting a reasonable horizontal spacing value, a passive roller is designed so that when rolling two kinds of steel plates, only two height values ​​are needed;

[0028] 2. Improve the original passive roller position adjustment device by using a pad and an adjustment plate. By changing the position of the adjustment plate, the passive roller height value can be adjusted, so that it can be accurately and conveniently switched between two height values.

[0029] The utility model discloses a working roll of a plate rolling machine for making the crucible boiler of a medium frequency furnace, comprising a working roll 1, an adjusting plate 2, a cushion block 3, and a steel plate 4. The working roll 1 comprises a roll body 101, a roll neck 102, and a rectangular bearing seat 103. There are two roll necks 102, which are distributed at both ends of the roll body 101. A rectangular bearing seat 103 is arranged at each end of each roll neck 102. Each rectangular bearing seat 103 is composed of two bearing seat units, and a bearing is arranged inside the rectangular bearing seat 103. There are two adjusting plates 2, two cushion blocks 3, and two steel plates 4. The working roll 1 can have two height values ​​by changing the position of the adjusting plate 2;

[0030] This embodiment retains the original two active rollers and their position adjustment devices, removes the original passive roller spiral mechanism, welds and blocks the upper part of the original passive roller sliding groove with a steel plate 4, sets a cushion block 3 in the middle of the two active roller sliding grooves and fixes them with screws, and designs the bearing seat at the end of the roll neck 102 into a rectangular bearing seat 103; the rectangular bearing seat 103 is set in the installation groove of the original passive roller, and the position of the adjustment plate 2 can be adjusted, which can be set between the cushion block 3 and the rectangular bearing seat 103, or between the rectangular bearing seat 103 and the steel plate 4. In this way, the working roll 1 can have two height values ​​by changing the position of the adjustment plate 2;

[0031] When a plate rolling machine is used to roll a rectangular steel plate to make a cylinder, the positions of the two adjustment plates 2 are both located between the cushion block 3 and the rectangular bearing seat 103, and the height value of the working roll is relatively large;

[0032] When a plate rolling machine is used to roll a sector-shaped ring steel plate to produce a cone, the positions of the two adjustment plates 2 are both located between the rectangular bearing seat 103 and the steel plate 4, and the height value of the working roll is relatively small;

[0033] When the rectangular steel plate is rolled into a cylinder and the fan-shaped ring steel plate is rolled into a cone using a plate rolling machine, the cylinder, cone and a round steel plate can be welded together to form a complete crucible boiler.

[0034] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
