Abstract
Abstract A roll stand is provided for multistand rolling mills such as wire rod mills having interchangeable stands in which a roll stand is provided with an input shaft adapted to be driven by an external drive means, an intermediate shaft is provided in said stand driven by said input shaft, said intermediate shaft driving rolls in said stand and connected to the input shaft by intermediate gears having a gear ratio adjusted to the diameter of the rolls whereby the peripheral speed of the rolls is uniform in any given stand regardless of roll diameter.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
119 words
In a multistand rolling mill such as a wire rod mill with three nonadjustable rolls per stand driven by an input shaft connected to an external drive means the improvement comprising at least one interchangeable roll stand interchangeable with each stand of said rolling mill, an input shaft in said interchangeable stand adapted to be driven by said external drive means, an intermediate shaft in said stand driven by said input shaft, said intermediate shaft driving said rolls and connected to the input shaft by intermediate gears having a gear ratio adjusted to a preselected smaller diameter of the rolls whereby the peripheral speed of the rolls is uniform in any given stand regardless of diameter of the rolls.
Claim 2
Dependent Claim
119 words
In a multistand rolling mill such as a wire rod mill with three nonadjustable rolls per stand driven by an input shaft connected to an external drive means the improvement comprising at least one interchangeable roll stand interchangeable with each stand of said rolling mill, an input shaft in said interchangeable stand adapted to be driven by said external drive means, an intermediate shaft in said stand driven by said input shaft, said intermediate shaft driving said rolls and connected to the input shaft by intermediate gears having a gear ratio adjusted to a preselected smaller diameter of the rolls whereby the peripheral speed of the rolls is uniform in any given stand regardless of diameter of the rolls.
Claim 3
Dependent Claim
133 words
A multistand rolling mill such as a wire rod mill comprising a housing adapted to receive a plurality of successive interchangeable roll stands each carrying three nonadjustable rolls, an input shaft in each stand driving said rolls, drive means in the housing drivingly engaging said input shaft, at least one replacement roll stand interchangeable with each of said roll stands having an intermediate shaft driven by said input shaft and driving said rolls, said intermediate shaft connected to said input shaft by intermediate gear having a gear ratio adjusted to a preselected smaller diameter of the rolls whereby said rolls when worn can be machined to said smaller preselected diameter and the peripheral speed of the smaller diameter rolls and the pass opening are uniform in any given stand regardless of roll diameter.
Claim 4
Dependent Claim
133 words
A multistand rolling mill such as a wire rod mill comprising a housing adapted to receive a plurality of successive interchangeable roll stands each carrying three nonadjustable rolls, an input shaft in each stand driving said rolls, drive means in the housing drivingly engaging said input shaft, at least one replacement roll stand interchangeable with each of said roll stands having an intermediate shaft driven by said input shaft and driving said rolls, said intermediate shaft connected to said input shaft by intermediate gear having a gear ratio adjusted to a preselected smaller diameter of the rolls whereby said rolls when worn can be machined to said smaller preselected diameter and the peripheral speed of the smaller diameter rolls and the pass opening are uniform in any given stand regardless of roll diameter.
Claim 5
Dependent Claim
100 words
A rolling mill stand for multistand wire mills having nonadjustable rolls adapted to use rolls which have been cut to smaller than normal diameter comprising a generally annular housing, an input shaft in said housing, an intermediate shaft in said housing, three spaced rolls journal sets in said housing receiving said smaller rolls, means connecting said smaller rolls to said intermediate shaft, and intermediate gear means connecting said input and intermediate shafts and having a gear ratio adjusted to the diameter of the rolls whereby the peripheral speed of the rolls and the pass opening are controlled to selected values.
Claim 6
Dependent Claim
100 words
A rolling mill stand for multistand wire mills having nonadjustable rolls adapted to use rolls which have been cut to smaller than normal diameter comprising a generally annular housing, an input shaft in said housing, an intermediate shaft in said housing, three spaced rolls journal sets in said housing receiving said smaller rolls, means connecting said smaller rolls to said intermediate shaft, and intermediate gear means connecting said input and intermediate shafts and having a gear ratio adjusted to the diameter of the rolls whereby the peripheral speed of the rolls and the pass opening are controlled to selected values.
Claim 7
Independent Claim
87 words
The method of reworking worn rolls for multistand wire rod mills and the like having nonadjustable rolls comprising the steps of a. machining three rolls from a stand to a uniform smaller diameter; b. mounting said rolls in a mill stand having an input shaft and an intermediate shaft drivingly connecting said rolls; and c. interconnecting said input and intermediate shaft with gearing having a ratio such that the peripheral speed of the machined rolls of small diameter is the same as that of the original rolls.
Claim 8
Independent Claim
87 words
The method of reworking worn rolls for multistand wire rod mills and the like having nonadjustable rolls comprising the steps of a. machining three rolls from a stand to a uniform smaller diameter; b. mounting said rolls in a mill stand having an input shaft and an intermediate shaft drivingly connecting said rolls; and c. interconnecting said input and intermediate shaft with gearing having a ratio such that the peripheral speed of the machined rolls of small diameter is the same as that of the original rolls.
