Description

Annealing furnace for entering and with drawing rolls easily}

The present invention relates to an annealing furnace used in a continuous annealing line of a cold rolling mill, and more particularly, to support the strip without manual operation of the operator during replacement of the annealing roll carrying the strip, and to automatically bind the annealing roll to the driving unit. The present invention relates to an annealing furnace that is easy to roll in and out of the annealing furnace, as well as to facilitate the operation of the annealing furnace.

In general, strips such as stainless steel, which have been rolled in a cold rolling mill, are subjected to continuous annealing and cooling operations, and then surface shape correction is performed. The furnaces of the annealing rolls installed in the conventional annealing furnace to transfer the strips are provided. Charging and withdrawal operations are shown in FIG.

That is, as shown in FIG. 1, the fastening bolt 130 of the roll shaft 120a of the annealing roll 120 bound to the drive shaft 110 of the one side driving motor of the annealing furnace 100 is separated. After separating the drive shaft (110a) from the drive shaft (110), the worker enters the annealing path (100) and raises the support (140) to lift the strip (S), while the other side roll shaft (120b) of the annealing roll (120). The annealing furnace cap 102 and the movable block 104 fixed to the annealing furnace 100 and fixed to the roll shaft 120b in the state of being fixed as the clamping device 150 schematically shown in FIG. Was drawn from the annealing furnace (100).

On the contrary, when the annealing roll 120 is charged into the annealing furnace 100, first, the strip S is set as the support neck 140, and a new annealing roll 120 is charged as the clamping device 150. The stopper 102 and the movable block 104 are fixed to the annealing furnace 100, and at this time, one side of the roll shaft 120a of the annealing roll 120 is fastened to the bearing block 110a of the drive shaft 110 by Annealing of the annealing roll 120 was performed in and out.

However, in the conventional annealing roll in and out operation as described above, the operator enters into the annealing furnace 100 and erects the strip S as the support wood 140, thereby stopping the operation of the annealing line during the cooling time of the annealing furnace. This lowers the strip manufacturing productivity.

In addition, due to the unstable operation in which the worker erects the strip as the support neck 140 in the high temperature annealing furnace, it becomes difficult for the worker to erect the strip quickly and stably, and at the same time, the drawing of the annealing roll 120 is stopped during the operation. There are problems such as damage to the surface of the strip as the strip 120 falls.

The present invention has been made in order to improve the various problems as described above, the object of the operation is to automatically set the strip without the operator's manual operation during the loading and withdrawal operation of the roll in the annealing furnace and the binding operation of the annealing roll and the drive unit By doing this, the operator does not directly enter the annealing furnace, so that the roll loading and withdrawal operation can be performed more quickly and precisely, thereby providing a roll-in and easy-rolling annealing furnace that improves productivity of the continuous annealing line.

Consists of a configuration that is connected to move back and forth and left and right.

Referring to the operation and effects of the present invention made in the above configuration in more detail as follows.

2 to 4, the annealing furnace is fixed to the inlet (1a) of the annealing furnace (1) to the first sensor 80 installed in the roll inlet (1b) formed on one side wall of the annealing furnace (1) While the upper tooth bar 2a of the stopper 2 is in contact, the annealing path stopper 2 and the moving block 4 are moved by the clamping device 6 in which the clamping device 6 is clamped to one side of the first roll shaft 10a. When the first sensor 80 is spaced apart from each other, the first cylinder 22 installed at the bottom of the annealing path 1 operates backward.

At this time, the rotating bar 28 is connected to the rod 22a of the first cylinder 22 through a link 24 and supported as a bearing block 26 through both annealing path side walls 1a and 1b. Rotate about 90 °, and eventually the inner strip S of the annealing furnace 1 is raised while the c-shaped support member, that is, the pedestal 20, which is integrally installed on the rotary bar 28, is erected in a horizontal state. Will be lifted.

Next, the annealing roll 10 is drawn out through one side inlet 1a of the annealing furnace 1 while the clamping device 6 is moved and the strip S is lifted as the supporting member 20. When charging of the annealing roll 10 is completed, when the above-mentioned first sensor 80 is operated by the quench bar 2a of the annealing furnace stopper 2 in close proximity to operate the first cylinder 22, The support member 20 is laid on the bottom of the annealing furnace, which is an initial position, and the outside of the pedestal 20 and the rotary bar 28, etc., prevents damage to components due to high heat in the annealing furnace. 29) covered entirely.

On the other hand, the other side wall (1b) of the annealing path (1) is provided with a binding portion 80 for connecting between the annealing roll 10 and the drive unit, in detail, as shown in FIG. When the first roll shaft 10a of the annealing roll 10 protrudes outward through the annealing furnace 1 through the opening 62a of the fixing plate 62 that is bolted to the other side wall 1b. The first roll shaft 10a is fitted into the moving block 60 of the binding means 40, which is moved back and forth and left and right via the fixing ring 74, and then through the moving block 60, the binding shaft 50. ) Is fixed.

At this time, the coupling shaft 50 is a universal joint (53b) connected to the drive motor (53a) installed on the outside of the annealing furnace (1), the drive shaft made of the first and second drive shafts (52a, 52b) of variable rotation operation The universal joint 54 is connected to the end of the 52, and eventually, when the driving motor 53a is operated, the binding shaft 50 rotates integrally, and thus the inclined end of the binding shaft 50 is inclined. The fastening pin 10a ′ of the first roll shaft 10a of the annealing roll is fixed to the groove 50a so that the annealing roll 10 is also driven integrally with the driving motor 53a.

In addition, as will be described in detail later, the drive shaft 52 is connected to the first and second drive shafts 52a and 52b which are variably inserted as gears and guide grooves formed inside each other. By the operation of the two cylinders 64 to perform the variable operation of the drive shaft 52 to move forward and backward.

At this time, the moving block 60 of the binding means 40 is installed to move back and forth and left and right, the reason for installing the movable block 60 in this way, the binding inside the moving block 60, The binding piece 10a 'installed at the end of the shaft 50 and the first roll shaft 10a of the annealing roll 10 is fitted, and at this time, the moving block 60 is moved so that an operator can check the binding state. For the sake of

In addition, looking at the movement of the moving block 60, when the second cylinder 64 horizontally coupled to the center of the fixed plate 62 installed on the one side wall (1b) of the annealing path forward or backward, the rod 64a The first moving plate 66 of the L-shape coupled to the movable plate 66 is supported by the first guide bar 65 horizontally coupled to both sides of the fixed plate 62.

At this time, when the third cylinder 68 horizontally installed on one side of the first moving plate 66 moves forward or backward, the b-shaped second moving plate 72 coupled to the rod 68a is connected to the first moving plate 66. It moves forward and backward in a state supported by the second guide bar 70 respectively provided inwardly of the moving plate 66, and the moving block 60 is fixed to the second moving plate 72 so that the movement Block 60 is to move back and forth and left and right.

In addition, second and third sensors 82b and 82c are respectively provided on the front and back sides of the support plate 82a provided with the fixing plate 62, and at the corners of the first moving plate 66, a tooth bar 84 is provided. ) Is installed.

Accordingly, the watch bar 84, which moves simultaneously with the forward and backward movement of the first moving plate 66, operates the second and third sensors 82b and 82c to adjust the amount of movement of the first moving plate 66. Adjust

As a result, the moving block 60 has the drive shaft 52 slightly longer due to the right movement of the second moving plate 72 and the forward movement of the first moving plate 66. When the first roll shaft 10a of 10 enters, the second moving plate 72 moves to the left and the first moving plate 66 moves backward so that the driving shaft 52 is coupled to the binding shaft 50 of the driving shaft 52 in a straight line. ) And the first roll shaft (10a) is performed, the separation of the binding shaft 50 and the first roll shaft (10a) is operated in reverse.

On the other hand, when the binding shaft 50 and the binding piece 10a 'of the first roll shaft 10a are fitted into the moving block 60, the fixing ring 74 is firmly fixed and bolted.

Therefore, when the driving motor 53a is driven, the drive shaft 52 and the annealing roll 10 are integrally rotated to perform annealing of the strip, and at this time, the driving motor is formed on one side of both side walls of the annealing furnace 10. The inner push rod shaft 96 of the worm wheel 94 engaged with the worm gear 92 rotated by the driving of the 90 moves up and down to support the annealing path plug 2 part.

Accordingly, compared to the conventional worker entering the annealing furnace to set up the strip and then charging and withdrawing the annealing roll 10, the operator can perform the roll loading and withdrawal operation more stably without the need for entering the annealing furnace. The operation rate of the annealing furnace can be improved.

As described above, according to the roll annealing furnace of the present invention, the operator automatically performs the operation of erecting the strip without the manual operation of the roll during the loading and withdrawal of the roll in the annealing furnace, and the binding operation of the annealing roll and the driving unit. Since it does not go directly into the annealing furnace, it is possible to perform roll loading and withdrawal operations more quickly and precisely, which has the advantage of improving the productivity of the continuous annealing line.

In addition, it is effective to prevent safety accidents and surface damage caused by falling of the strip, which occurs when the worker enters the annealing furnace.
