Abstract
A billet is rolled in a rolling mill into a first process section in a succession of roll stands arranged along a first pass line. The first process section is either delivered as a finished product to a cooling bed or alternatively slit into second and third process sections which are subjected respectively to additional rolling in finishing blocks arranged on second and third pass lines parallel to the first pass line. At least one of the finishing blocks is shiftable onto the first pass line in order to subject the first process section to additional rolling prior to delivering it to the cooling bed.
Claims6
A rolling mill comprising:
- a plurality of roll stands arranged successively along a first pass line for rolling a billet into a first process section;
- a cooling bed;
- first guide means for directing said first process section along said first pass line for delivery to said cooling bed;
- finishing blocks arranged on second and third pass lines parallel to said first pass line;
- slitting means for subdividing said first process section into second and third process sections;
- second guide means for directing said second and third process sections respectively to said second and third pass lines for continued rolling in said finishing blocks into products delivered to said cooling bed;
- and
- means for shifting at least one of said finishing blocks onto said first pass line for additional rolling of said first process section prior to delivery thereof to said cooling bed.
In a rod rolling mill wherein a billet is rolled into a first process section in a succession of roll stands arranged along a first pass line, and said first process section is either delivered to a cooling bed or alternatively slit into second and third process sections which are subjected respectively to additional rolling in finishing blocks arranged on second and third pass lines parallel to said first pass line, the improvement comprising shifting one of said finishing blocks onto said first pass line, and subjecting said first process section to additional rolling in the thus shifted finishing block prior to delivering the same to said cooling bed.
A method of rolling long products, comprising:
- rolling a billet into a first process section in a succession of roll stands arranged along a first pass line and
- (a) directing said first process section to a cooling bed;
- (b) as an alternative to (a);
- (i) slitting said first process section into second and third process sections;
- (ii) rolling said second and third process sections into products in finishing blocks arranged on second and third pass lines parallel to said first pass line;
- and
- (iii) directing the products emerging from said finishing blocks to said cooling bed;
- and
- (c) as an alternative to (a) or (b)
- (i) shifting one of said finishing blocks to said first pass line;
- and
- (ii) continuing the rolling of said first process section in the thus shifted finishing block before directing the product emerging therefrom to said cooling bed.
