A tape-shaped rolling stock (8) having a top edge (14) is to be rolled in a rolling mill. The rolling mill has a roll stand (1) with working rolls, arranged one on the input side of the roll stand (1) roller table (2) and a control device. The work rolls form a nip. The control means controls the roll stand (1) in such a way that the work rolls rotate at a peripheral speed.
An algorithm has been developed for the 2000 and 2500 mills at the Magnitogorsk Metallurgical Combine to obtain hot-rolled strip with prescribed characteristics for their cross-sectional profile and flatness. Roll profiles with parameters conforming to existing specifications are obtained by successive execution of the algorithms. The algorithms' use makes it possible to produce strip that ...
Casting / Forged Alloy Steel Rolling Mill Rolls for Cold Rolling Factory The raw billet material of Alloy Steel Rolling Mill Rolls is manufactured with high quality steel molten by arc furnace, due to the advanced casting and thermal traetment technique, such roll is of very high intensity. Owing...
•Roll-strip contact length L •Average strip width w –despite the fact that spreading, or an increase in width, may actually occur if edger mills are not used •Average true stress of the strip in the roll gap Y avg •Assumes no friction and thus predicts lower roll force than the actual value •Power per roll (SI units)= pFLN / 60,000 kW
The utility model relates to a section steel mill roll-wheel device, which is characterized in comprising a frame, a reducer, supports, a lower slider, an upper slider, a bearing, a pressure plate, round nuts, an upper shaft, a lower shaft, key bars, an upper roll wheel, a lower roll wheel, an upper gear wheel, a lower gear wheel, an upper chain wheel, a chain and a lower chain wheel; the ...
Roll wear, along with deformation in the mill and the plasticity of hot steel may also cause variations from the published dimensions of rolled structural shapes. Therefore, to meet camber or sweep tolerances, they may need straightening by the producer. Other tolerances are subject to negotiation with Nucor-Yamato Steel.
The rolling mill stand, for example a four-high rolling mill stand, for strip mills, with adjusting devices acting horizontally and/or vertically on the rolls for roll nip regulation is characterized by a dual bearing for the work rolls (1, 2) in respectively two inner and outer mounting members (5, 6), which latter, for attaining the same change in shape over the strip width, are horizontally ...
A new type of compact mill called a "satellite mill" is used for producing T-shaped profiled strip from flat strip. The mill comprises one large-diameter flat roll (central roll) and five smaller-diameter caliber rolls (satellite rolls) arranged along the periphery of the central roll. The flat strip is continuously passed through the five gaps between the central roll and the satellite ...
The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased. Rolls the working members (instruments) of a rolling mill. Rolls perform the basic rolling operation: the deformation (reduction) of the metal to give it the required dimensions and shape. The rolls consist of three elements: the barrel, two ...
skewed roll rolling mill, horizontal rolls of which barrel length have to be adjusted within a short time on line are needed, and for the purpose, the barrel length adjustable horizontal roll as shown in Fig. 5 is used. In the construction of the barrel length adjustable horizon-tal roll, a highly reliable roll barrel length adjusting mechanism is
The invention discloses an F-shaped steel mill roll double-hole type and a rolling method. The double-hole type is formed by splicing an upper roll and a lower roll of a rolling mill and is a pair of F-shaped steel hole types which is symmetric along an axial line AA and are communicated through a connecting area. The axial line AA is perpendicular to the horizontal central ling BB of the ...
