摘要:
The present invention relates to a water-cooled handling roll (100) for handling a load (50), in particular a thin slab, in a furnace for temperature heating, maintaining and for buffering, arranged between casting and roughing, in a continuous casting and rolling process for thin carbon steel slabs. The roll (100) comprises a first internally hollow shaft (110), which is coated by an insulating and/or refractory material and a plurality of wheels (25) connected in stably fixed manner to an outermost surface (111) of the first shaft (110) to handle and support the load (50). According to the invention, the roll (100) also comprises a second shaft (120) arranged within an inner cavity of the first shaft (110) in position coaxial to the first shaft (110) and so as to define a gap (30) between the first shaft (110) and said second shaft (120). The roll (100) further comprises cooling water circulation means housed at least in part within said second shaft (120).

The invention relates to a device for bending sheets of glass running between a bed of upper rolls and a bed of lower rolls forming a shaping bed that pinches the sheets as they run, said shaping bed being disposed in a path having a curved profile in the running direction of the sheets of glass, said shaping bed comprising at least one roll of what is known as the rod/sheath type comprising a fixed metal rod preformed in a curved profile lengthwise and a flexible sheath that is able to rotate about said rod, said sheath being rotated about said rod. The roll of the rod/sheath type may comprise a metal rod preformed in a curved profile lengthwise and a flexible sheath that is able to rotate about the rod, said sheath comprising a first envelope made of a polymer material and a second envelope made of a flexible metal material disposed around the first envelope, the first and the second envelope rotating together as one.

A conveyor for a sheet glass tempering furnace, comprising a roller conveyor (2, 3) and an inclined airborne conveyor (4), as well as support and transport rollers at a lower edge of the airborne conveyor (4). The roller conveyor includes a horizontal level conveyor (2) and an adapter conveyor (3) between the horizontal level conveyor and the airborne conveyor. The adapter conveyor (3) features a horizontal level upstream end (3a) and an inclined downstream end (3b), the inclination angle of which matches substantially that of the airborne conveyor (4). The adapter conveyor (3) has its rollers (13) increase in inclination step by step when proceeding from the upstream end (3a) towards the downstream end (3b)

A press bending station (12) for heated glass (G) sheets includes a lower wheel bed (36) having a lower support (38) and wheel assemblies (40) with detachable connections (46) to a drive mechanism (48) having a continuous drive member (112) of the lower support to provide rotational driving of a wheel (44) of each wheel assembly. An actuator (62) provides relative vertical movement between a lower press ring (52) on lower mount (50) and an upper press mold (58) on upper mount (56) using lower (88) and upper (90) vertical operators. Upper press mold has a forming face (60) provided with vacuum (66) and lower press ring has curved shpae (54) which presses the glass sheet against the forming face of the upper press mold. The wheel bed can have a curved shape or a flat shape. Connection and detachment of the wheel assemblies facilitates switching from one production job to the next.
摘要:
In a glass-ribbon conveyance assisting device which is applied to a glass-ribbon conveyance device configured to convey a glass ribbon on a plurality of rotating glass-conveyance rolls, the glass-ribbon conveyance assisting device includes a rotary drive section, a plurality of rolls configured to be rotated by the rotary drive section, an annular belt configured to rotate while running with flexion under a state where the rolls have been inserted into the belt, and a wheel configured to press the glass ribbon which is conveyed on the belt. The glass ribbon is conveyed on the belt by a drive of the belt under a state where width-directional both end portions of the glass ribbon are sandwiched between the belt and the wheel.
摘要:
The invention relates to a roller (21) from a refractory material, for example in vitreous silica, for transporting a flat article provided at its end with a new arrangement for rotationally driving it as well as to an assembly of such a roller and its driving device. This roller (21) comprises an external surface (2), an inner surface (5) and two side surfaces (12), at least one side surface having indentations (22) parallel to the roller axis (3) and spaced apart from the external (2) and inner surface (5) for receiving rotationally driving pins (8), it is characterized in that at least one of the indentations (22) of the roller is provided with a metal jacket (24). The invention permits to avoid the breakage of the roller around the driving indentations.
摘要:
The invention relates to a method and apparatus for bending and tempering or heat-strengthening a bidirectionally curved glass panel. A heated glass panel is curved in a main bending direction parallel to the advancing direction and in a sagging direction transversely to the advancing direction. Curving in the sagging direction is performed by bending conveyor rolls (4), the bending of which is effected by turning lever elements (7) bearing-mounted for free rotation on the ends of the conveyor rolls. Between the outer ends of the lever elements (7) is a push rod (8), whose length is quickly variable by means of an actuator (9).
