Description

FIELD OF THE INVENTION This invention relates to rolling production and can be used in tube rolling and section rolling mills of hot rolling.

The purpose of the invention is to increase the service life of the rolls.

In the described method, moisture is removed by elastic clamping elements, after which the surface of the shaft is blown with a jet of burning gas, for example natural gas, the combustion products of which reduce frictional forces in the deformation zone and the coolant is supplied from the metal outlets from the rolls.

The drawing shows the elements of the cage, providing an implementation of the method of increasing the resistance of the rolling rolls.

A deformable strip 3 is defined in the gap between the upper 1 and lower 2 rolling rollers 3. The cooling fluid is removed from the working surface of the rolling rollers 4 by the pressure rollers 4 from the rolling mill rolls, and then burners 5

a stream of burning gas is directed onto the working surface of the roll. The cooling roll fluid is supplied from the back of the stand using devices 6.

The method is implemented as follows.

To the work rolls 1, 2 of the tube rolling mill or steel mill, the coolant from the devices 6 is supplied only from the exit side of the strip 3 from the rolls. Part of the coolant along with the rolls 1,

2 moves to the task side of the strip

3c to the rolls 1, 2, where the pressure rubber rollers 4 are partially or completely removed from the working surface of the rolls 1,2.

To ensure complete removal of moisture from the working surface of the rolling rolls 1, 2, the latter are blown with a stream of burning gas from the burners. The jet of burning gas dries the working surface of the rolls 1, 2 and with it the working waste of the burning gas in the form of soot, soot, etc. fall into the deformation zone, providing lubrication of the working surface of the rolls, reducing their wear and

providing a reduction in the energy-power parameters of the rolling process, and in order to increase soot and soot in the combustion products, special technological methods can be applied, such as. for example introducing hot fuel oil into the stream and

SUMMARY OF THE INVENTION Method for processing rolling rolls in combustible rolling, comprising feeding 0 on their cooler surface from the side of the deformation zone and lubrication from the entrance to the deformation zone with the preliminary removal of moisture from the surface of the roll in front of the lubrication zone, so that and, in order to increase the life service rolls, moisture is removed by elastic clamping elements, after which the surface of the roll is blown with a stream of burning gas.
