摘要:
A roll stand with roll rings which are placed from one side or in a cantilivered manner on a pair of adjustable roll support shafts which are supported on two sides. Both roll support shafts have extension journals which project beyond the roll rings. Journal bearings can be slid onto and are fixable on the extension journals. The journal bearings have bearings housing which are connected with each other in a frictional engaging manner for absorbing rolling forces by means of piston-cylinder units which can be actuated by a pressure medium and are movable parallel to the direction of adjustment of the roll support shafts. On of the bearing housing is connected to the piston rods of the piston-cylinder unit and the other bearing housing, which supports the piston-cylinder units, sliding guide means for the piston rods. The roll stand further includes additional piston rods. The roll stand further includes additional piston-cylinder usits arranged between the two bearing housings. the cylinders and pistons of the additional piston-cylinder units are guided by the piston rods of the other piston-cylinder units which connect the bearing housings. The pistons of the second piston-cylinder units rest against one of the two bearing housings and the cylinders of the additional piston cylinder units rest against the other of the bearing housing. Pressure can be applied to the additional piston-cylinder units independently of the other piston-cylinder units.
摘要:
The invention relates to a method and a device for detecting contaminants in a fluid (1), wherein the fluid (2) that is contaminated with particles is conveyed by a first metering pump (3) to a device (4) for measuring the contamination or the particle density in the contaminated fluid (2). Said method and said device are each characterized in that, before entering the device (4) for measuring the contamination, the fluid is mixed with purified fluid (5) in a defined mixing ratio, the particle density or the contamination of the mixed fluid (6) is measured, and the particle density or the contamination of the contaminated fluid (2) is determined by an arithmetic unit (7).
摘要:
A torque support for a converter tilting drive mounted on a shaft journal. The supports are provided on the gear housing that accommodates the shaft journal to be driven. The supports support the gear housing on the structure carrying the converter. To this end, the supports are embodied in each case as dual action hydraulic piston-cylinder units that are independently anchored on the structure in an articulated manner.

A method and a device detects contaminants in a fluid (1). Fluid (2) with particles is conveyed by a first metering pump (3) to a device (4) for measuring the contamination or the particle density in the contaminated fluid (2). Before entering the device (4) for measuring the contamination, the fluid is mixed with cleaned fluid (5) in a defined mixing ratio. The particle density or the contamination of the mixed fluid (6) is measured. The particle density or the contamination of the contaminated fluid (2) is determined by an arithmetic unit (7).

The invention relates to a descaling device which can be operated in an optimal manner with respect to the efficiency, descaling quality, energy and water consumption and is readily available. The aim of the invention is achieved such that the spray nozzles (12), which are instrumental in descaling the steel material (2) in the descaling device (8), are designed as static nozzles and as dynamic or rotating nozzles. The static nozzles form, together with the spray bars, pairs of spray bars (13) and the dynamic or rotating nozzles form, together with spray units, rows of pairs of spray units (23).
