摘要： In a known method for the manufacture of a tube made of a vitreous material, especially of quartz glass, a hollow cylindrical semifinished product made of a vitreous material is carried essentially vertically to a heating zone, wherein it is heated and drawn off downwards—without the use of tools—to the tube by forming a transitional area from semifinished product to tube, while diameter and wall thickness of the tube are continuously measured, and the tube's measured geometrical data being used to generate a control signal with the aid of which a pressure difference is regulated between pressure P1 in the interior space of the semifinished product, the transitional area and the tube, as well as pressure P2 in the heating chamber which is regulated in the heating zone at least in the transitional area from semifinished product to tube and its adjacent tube area. This method is to be developed further so as to enable the processing of a broader spectrum of hollow cylindrical semifinished products to tubes with the desired inside and outside dimensions. This task is solved according to the invention such that for the manufacture of tubes with the ratio of their outside diameter (DRa) to their inside diameter (DRi) being greater than the ratio of the outside diameter (DHa) to the inside diameter (DHi) of the semifinished product—pressure P1 in the inside space of the semifinished product, the transitional area and the tube being kept at a value which is smaller than the value of pressure P2 in the heating chamber, with pressure P1 being maintained by means of a suction (vacuum) pump.

摘要： In a known method for producing a tube of quartz glass by elongation, a hollow cylinder of quartz glass is continuously supplied to a heating zone, softened therein zone by zone, and a tube strand is drawn in the direction of a drawing axis out of the softened region by using a roll puller, the roll puller comprising a frame by which a plurality of puller rolls are fixed, which are rotatable around a rotation axis and which are distributed over the circumference of the tube strand and adjoining the tube strand with their cylindrical outer surface. Starting therefrom, to indicate a vertical drawing method in which a high draw ratio can also be accomplished with little constructional effort by using a take-off unit in the form of a roll puller and which simultaneously allows an optimization of the dimensional stability of the quartz glass tubes obtained, and which particularly avoids material losses caused by ovality and siding, the invention suggests that the frame of the roll puller s stationary, and the hollow cylinder and the tube strand are rotated about the drawing axis relative to one another, the relative rotation being set to a range between 0.01 and 5 revolutions per linear meter of drawn-off tube strand.

摘要： In a known drawing method for producing cylinder-shaped components from quartz glass, a quartz glass strand (10) is drawn in the direction of a drawing axis (12) from a deformation region of a quartz glass mass (9) and pieces having a cutting length (S) are separated therefrom. The cylinder-shaped components are produced from the pieces. In order to provide a simple drawing method for producing quartz glass components, wherein the effects of geometric disruptions, in particular variations in diameter and material rejects, are reduced, the separation of the quartz glass strand (10) is carried out at a separating position (T), wherein the distance of the separating position from the deformation region (9) is set in a way such that a disruption of the quartz glass strand geometry created by the separation lies in an end region of the component to be produced or between two neighboring components during a subsequent separation.
