Definitions
- the task is solved by first producing shorter pipe or roller sections.
- the tube or roller sections are formed individually. In particular, they may consist of cast steel, rolled steel or, more preferably, forged steel.
- the tube or roller sections are accordingly formed separately, for example in a process of primary shaping such as casting (cast steel) or forming such as forging (forgings).
- the steel alloys preferred according to the invention have improved mechanical properties. It has surprisingly been found that according to the invention used higher carbon steels having a carbon equivalent of at least 0.45 at the wall thicknesses of typically at least 130 mm, which are large for web processing rolls, can be joined by electron beam welding in high quality.
- the thick-walled pipe sections of heavy or non-weldable steel having a carbon equivalent of at least 0.45, preferably at least 0.6 are metallurgically bonded to one another prior to further processing by means of an electron beam of sufficient power.
- the electron beam directed at the joint, preferably at the butt joint, between the roller sections and in their flight evaporates the steel and drills a capillary. Around it, the steel melts. If the beam reaches the required welding depth, preferably the inner bore or the hollow cross section, the pipe sections are set in rotation about their common central longitudinal axis, preferably at a uniform rotational speed.
- the preferably stationary jet then melts the material coming towards it during the rotational movement, which material connects to one another after passing through the jet.
- the pipe sections to be joined and subsequent roller portions are preferably pre-heated in the region of the connecting joint prior to welding, preferably to a temperature of at least 150 0 C, more preferably to a temperature of about 400 0 C.
- axial channels preferably drilled, which are flowed through during operation of the roller by a thermal fluid.
- fastening means are preferably produced for the attachment of each flange pin.
- the flange pins serve to pivot the roll and, in the preferred embodiments, as the inlet and outlet for the thermal fluid.
- Figure 2 shows a cross section through the butt joint, i. an end view of one of the pipe sections, in the example of the pipe section 2.
- the pipe sections 1 and 2 located in the joining position are continuously driven in the rotational direction D about the rotation axis R.
- the direction of rotation D corresponds to the clockwise direction.
- the electron beam welding device 3 is arranged and aligned such that its beam outlet faces the outer peripheral surface of the pipe sections 1 and 2 approximately at the 3 o'clock position and the electron beam 4 is inclined at an angle ⁇ to a straight line extending from the Center of the Strahlauslasses to the rotation axis R extends. Because of the positioning at the 3 o'clock position, said connecting line extends horizontally.
- the electron beam 4 is directed at the angle ⁇ obliquely downward.
- the enamel capillary 5 runs upward as seen from the inside outward. Due to the non-radial orientation of the electron beam relative to the axis of rotation R, a weld pool fuse is obtained.
- the angle ⁇ is between 15 ° and 25 °, preferably 20 °.
