Abstract

The solution relates to the cooling supply rolling mills, especially afterwards redeveloping stool, the essence of which is that the connecting cube flips over connecting bore to the right bore, which it is guided by the lower half-timber, the distance cube or the central part of the upper half frame, wherein between the parts is inserted seal.

Description

(54) Rolling mill coolant supply

The invention relates to a cooling mill inlet of a rolling stand, in particular to a remodeling stand, the essence of which is that the connecting cube rolls through a connecting bore into a right bore which is guided by the lower half-frame, spacer or central part into the upper half-frame. seal.

BACKGROUND OF THE INVENTION The present invention relates to the supply of coolant to a rolling mill, in particular to a convertible mill.

The coolant inlets used up to now have been provided by means of vertical tubes and hoses to the cube to the system itself and to the mobile cooling systems.

The disadvantage of this solution is, in general, the necessity of carrying out tubing on the surface of the stool, of its anchoring and of the location of relatively large pipes. In the case of remodeled stools, these problems are increasingly subject to the need for age regulation of the supply due to stool neo-duo or universal treatment. A further disadvantage would be the supply of the coolant of the centering member for cooling both vertical cylinders.

Said drawbacks are eliminated by the coolant supply by drilling in the half-rim and central part according to the invention. It is an object of the present invention to transfer the coolant from the supply cube to the lower half-angle and rise to all other parts.

These are the central part e the upper half-circle in the design as unlverséla and the upper half-frame through the spacers in the stool design duo. The bores are sealed between the parts.

The boreholes are used for the cooling of horizontal cylinders in the half-circles, and the boreholes for the cooling of vertical cylinders in the universal design are made in the central part. A bore is formed from the supply cube into the inlet column at the drive side, and at the top of the upper half-rim is a connecting piece through which the coolant is transferred to the inlet column at the operator side. Tlm provides the possibility of supplying coolant to both vertical cylinders.

When changing the stool from duo to universal and vice versa, it is not necessary to adjust the length of the vertical coolant tube. This is done automatically by assembling the necessary components and anchoring them - the damping is also done sealing. The outlets for cooling the upper and lower cylinders remain constant and always connected to a source of coolant.

The coolant connection system when assembling the stool as a duo is shown in Figure 1 and the coolant connection system when assembling the stool as a universal is shown in Figure 2.

Between the upper half-frame χ and the lower half-frame £ are spacers £. A connecting bore 18 is provided from the connecting block 1 to the right bore. This bore 2 on the right is provided by the lower radius 21 of the spacer bar J, and the upper radius χ.

In the upper half-radius χ, the right bore 6 is connected to the bore 2 by the left connecting piece 2. The right bore 2 is formed by upper openings 11 for cooling the upper cylinder I and a lower opening 12 for cooling the lower cylinder 17.

The right bore 2 and the left bore 2 are sealed between the upper half-frame χ and the lower half-frame 2 and the spacer bar 6 by a gasket 6 which is pulled together with the individual parts of the stool by anchors ia.

In the rolling mill assembly in the universal arrangement, there is a central section 2 between the upper half frame χ and the lower half frame 2 in which the vertical cylinders 12 are located. The coolant line through the connecting cube J, connecting bore 16, bore 2 right, connecting piece 2 ® bore 2 left remain the same as in the duo version as well as the gasket 8, with the individual parts being anchored by anchors X £, the opening χχ.the top and the opening χ dolní down.

In the central part J there is an opening 13 right for cooling the right vertical cylinder 12. ^{8 an} opening 14 left for cooling the left vertical cylinder 15.

The coolant supply system can be used on most of the rolling mills, but the biggest advantages are in the case of folded constructions, where the height of the outlets is changed to the cooling of the rolls. A typical example of this case is the redesigned stool.
