Embodiment Construction

[0015] first reference figure 1 , 10 in the figure represents a high-speed finish rolling module. The module is powered by a drive motor 14 via a geared speed increaser 12 .

[0016] Refer again figure 2 , 3 and 5, it can be seen that the module comprises a row of rolling stands 16 arranged staggered on both sides of the pass line P. The rolling mill stand has cantilevered work roll pairs 18 staggered with a difference of 90° for twist-free rolling of the product. The rows of mill stands on each side of the rolling line are mechanically connected to each other and to the speed increaser 12 via the overall shaft sections 20 interconnected by couplings 22 .

[0017] Each mill stand 16 includes a frame 24 closed at its upper end by a front cleat 26 which supports a side frame body 28 projecting inwardly through the opening. In each frame 24 , each main shaft section 20 carries a helical gear 30 which cooperates with a mating helical gear 32 on one of a pair of parallel driv...

Abstract

A system is disclosed for applying a liquid lubricant to first and second components enclosed in a housing, with the lubricant applied to the second components being exposed to contamination by a liquid coolant applied to the exterior of the housing, and with the lubricant applied to the first components being substantially isolated from the liquid coolant. The system includes a partition internally subdividing the housing into a first chamber containing the first components and a second chamber containing the second components. Lubricant is delivered from a storage tank to the housing for application to the first and second components. A first conduit network communicates with the first chamber for returning the lubricant applied to the first components to the storage tank, and a second conduit network communicates with the second chamber for returning lubricant applied to the second components to the storage tank. A liquid coolant removal unit in the second conduit network removes liquid coolant from the lubricant being returned to the storage tank.

Description

(1) Technical field [0001] The present invention relates generally to a lubrication system, particularly but not limited to a rolling mill lubrication system in which a liquid lubricant is applied to mating components and some but not all of the lubricant is susceptible to contamination by externally applied cooling water and Entrained particulate matter such as dust, mill scale, etc. (2) Background technology [0002] In conventional rolling mill lubrication systems, such as employed in the high-speed finishing block described in U.S. Patent No. 5,577,405 (Shore et al.), liquid lubricant is pumped from a remote storage container to supply individual mill stands , in which the liquid lubricant is supplied to the bearings, gears and other related components installed in the rolling mill stand through the internal network. At the same time, cooling water is continuously supplied from the outside to the work rolls and associated guides. [0003] Most internal components, such...
