1. Guide Box

2. Roller Holder

1) Roller Holder heads below DU100 type can be fixed and removed from the Guide Box by hand.

2) For fixing and removing of Roller Holder heads of types over DU 130 type, use a chain block.

Assembly:

1) The gap between the hole of the Guide Box and cylindrical surface of Roller Holder is very small. Therefore, proper care should be taken when the Holder head is inserted into the Guide Box, so as not to have any axial deflection. If the Roller Holder is inserted incorrectly by force, it will be difficult to take out.

2) Grease the contact surfaces of the Roller Holder head and the Guide Box before assembly. After assembly, feed sufficient grease from the nipple again.

3) After use, to make the removal of Roller Holder from Guide Box easy, wash off scale first and turn Roller Holder by Twist Pinion and then remove the Roller Holder without force.

4) Take necessary precautions and care not to damage (scratch, scrape, etc.) these contact surfaces of Guide Box and Roller Holder. If any scratching, scraping etc., occurs, repair such damages early by grinding.

3. Fix the Roller Holder with the two bolts provided for this purpose, after making sure that the Twist Angle is correct.

Correction of Twist Angle during Actual Rolling:

During operation, actual stock sizes change from the design value. Therefore, actual stock size changes should be taken into consideration and Twist Angle should be adjusted accordingly. Check the entry angle at the feed point of rolls and make necessary corrections.

q = Roller Holder Twist Angle

a = Stock Twist Angle

When the Twist Pinion Ratchet Handle is turned backwards, Roller Holder will move in a clockwise direction.

When Twist Pinion Ratchet Handle is turned forward, Roller Holder moves in an anticlockwise direction.

6. Check again whether “e” is same on both sides.

7. Insert the Key Bolt into key way.

VI. Guide Roller Adjustment Mechanism

Description

When the Ratchet Handle is moved, Left Screw Spindle and the Right Screw Spindle move in opposite directions. Forces P₁ and P₂ are applied due to this moment. Thus, Roller Holders are opened or closed.

Instructions for Operation and Application

Selling of Screw Spindles:

When looking in the direction of rolling, (Guide Roller in Front), Right Screw Spindle should be on tile right side and Left Screw Spindle should be on the left side.

Gap adjustment procedure:

Make “e” same on both left and right sides. Depending on the movement of the Ratchet Handle, the Roller Holders will cither open or close the Roller gap symmetrically.

Operation of Ratchet Handle:

1. When the Ratchet Handle moves forward, the roller gap closes. When it moves backward, the Roller gap opens.
2. Loosen the Roller holder Fixing Bolts and move the Ratchet. If the Fixing Bolts are not loosened before moving the Ratchet Handle, there will be very big sirens on the Roller Holders. This might cause damage.

Standard Guide Roller Distance Adjustment Procedure

1. When the Ratchet Handle is moved forward, the Roller gap closes. When it is moved backward, the roller gap open.

2. Adjust the Roller distance using the Gauge Bar.

Relationship between a Ratchet Handle movement of 90° and Roller distance

Handle movement of 90″ Roller gap opens or closes by

Type of Roller Guide EP20 EP25 EF40 EP55 EP70

Distance – l mm. 0.55 0.53 0.5 0.5 0.44

Type of Roller Guide EP90 EP110 RP140 EP70 EP200

Distance – l mm. 0.44 0.44 0.5 0.92 0.9

VII. Roller Gap Adjustment

Roller Gap Adjustment depends on:

1. Stock size

2. Shape of stock

3. Type of rolling (Tandem, Gullet, V-H with no twist or H-K with twist)

4. Distance from roll stand to roll stand.

5. Length of loop.

6. Speed of rolling.

7. Others

Entry Roller Guides take all the above-mentioned factors into account and ensure smooth and stable operation. Changes of stock size that occur during rolling should be taken into consideration. The best procedure to adjust the Roller gap is to lake into consideration the above-mentioned factors and set the gap according to your experience in the mill.

Roller Gap Adjustment:

1. Gauge Bar lightly [ouches (lie roller, (zero holding)

2. Roller gap smaller than the Gauge Bar. (minus holding)

3. There exists a small gap between the Rollers and the Gauge Bar (plus holding)

VIII. Check List

Important features of assembly, disassembly and adjustment:

1. Check and make “e” same on both sides to ensure that Roller Holders move symmetrically. (Same distance)

2. The bolts are delicate and make sure they are handled properly to ensure that no damage is done.

3. Before assembly, grease the parts well. After assembly, feed grease again through the flexible hose.

4. Ensure that bearings turn smoothly, and see that water, scale, etc., do not get into the bearings.

5. There is no necessity to disassemble the Ratchet Mechanism at an early stage. Apply grease sufficiently well to the Ratchet Mechanism.

6. In case there is a gap between Ratchet Wheel and bracket, insert Shims.

7. When moving Ratchet Handle, loosen Roller holder fixing Bolts. If not bracket will wear and brake.
