摘要： A method and apparatus for rolling steel material into steel products having flanges such as rails and H-shaped products by use of a universal rolling mill wherein the cross section along the direction of axis of the vertical roll of the universal rolling mill has a convex shape. Therefore, the rolling by such vertical roll gives a reduction of nearly V-shaped concentration to the part of the steel material contacting said vertical roll and to be made into a flange.

摘要： A wet gas scrubber, wherein a mechanism for dividing a gas flow into two and for making the cross-sectional area of the gas flow paths variable is provided in a throat part and guides are provided respectively on the upstream side and downstream side of said mechanism so that the pressure loss may be reduced and further the relation between control variables of the variable cross-sectional area mechanism and the gas flow rate may be linearized. The guides are wedge-shaped with the broad ends at the variable mechanism. In one embodiment the variable mechanism comprises a rotor shaft extending transversely of the throat part and a rotor mounted on the shaft. The rotor has a rectangular longitudinal cross section and a transverse cross section which has a different length than width. The rotor has a transverse cross section bounded by a closed curve. In another embodiment the variable mechanism comprises a pair of spaced flexible and stretchable plate members extending along the inside portions of the throat parts. Plate moving elements are connected between the plate parts and are coupled to the plate members for bending the plate members outwardly into the throat parts. In still another embodiment the variable mechanism comprises two spaced sets of bulkhead plates extending along the inside portions of the throat parts. Each set including a first bulkhead plate having one end pivotally mounted on the venturi tube adjacent one gas flow guide and a second bulkhead plate slidably mounted adjacent the other gas flow guide and hingedly coupled to the first bulkhead plate. Plate moving members are connected between the sets of plates and are coupled to the sets of plates for moving the sets of bulkhead plates outwardly into the throat parts.
