Patented Aug. 4, 1936 COLD-ROLLING STEEL STRIP Walter 0. Ever-ling, South Euclid, Ohio, assignor to The American Steel and Wire Company of New Jersey, a corporation of New Jersey Application January 21, 1935, Serial No. 2,811
2 Claims.
This invention relates to the art of cold-roll-, ing steel strip, one of the objects being to produce strip covered with a minimum amount of oil by means of a cold-rolling mill having the conventional oil-lubricated working rolls.
An example of the invention is illustrated by the accompanying drawings, in which:
Figure 1 shows strip passing over the bottom roll of a mill to which any example of the invention is applied.
Figure 2 shows the edges of the strip and the ends of the rolls.
Figure 3 shows the strip leaving the rolls and illustrates the operation of the invention.
These drawings show the working rolls I of a cold mill. The oil is applied in several ways, but in all cases it is carried on the rolls so as to contact the strip, marked S in the drawings, as it enters the working pass.
Because of the seal formed by the heavy-pressured contact of the rolls I with the strip S, any excess oil is effectively prevented from flowing onto the latter except at its edges. Since the oil is not sealed at the dead portions of the pass, it there forms rings through which the strips edges are dragged, some oil clinging to these edges and eventually creeping from them onto the surfaces of the strip to a sufiicient extent to interfere with bright annealing operations.
The remedy heretofore used consisted of various methodsand devices for wiping or otherwise removing this oil from the surfaces of the strip. Such procedure has drawbacks, but was resorted to for the lack of anything better.
Now the present invention covers a method of producing cold-rolled strip, which includes rolling the strip by means of a cold-rolling mill having oil-lubricated working rolls, while blowing the lubricating oil away from the pass of the rolls not occupied by the strip, in a direction such that it will not contact the latter as it leaves the rolls.
v It is apparent that this method is particularly part of the pass not being actively used and which,
therefore, contains 011.
Certain apparatus is also covered by the invention, and this will now be disclosed with the aid of the drawings.
A bar 3 is fastened transversely across the mill at a level well working rolls I and on the exit side of the latter.

I claim:

2. A method of producing cold-rolled metal strip, including rolling said strip by means of a cold-rolling mill having oil-lubricated working rolls, while blowing the oil away from the portions of the pass of said rolls adjacent said strip that is not occupied by the latter, in a direction opposite the travel of said strip so it leaves said rolls.
