Method and device for drawing a quartz glass cylinder from a melt crucible

The invention relates to a known method for drawing a quartz glass cylinder from a melt crucible comprising an inner crucible chamber extending in the direction of a center crucible axis and bounded by a side wall and a floor, wherein SiO2 granulate is fed into the melt crucible and therein softened into a quartz glass mass, and said mass is drawn vertically downward as a cylindrical quartz glass strand by means of a first draw-off device through a first draw nozzle provided in the floor of the melt crucible, and the quartz glass cylinder is cut off therefrom. In order to disclose a method starting herefrom and allowing the production of homogenous quartz glass cylinder at simultaneously high levels of productivity, the invention proposes that at least one second quartz glass strand is drawn off through at least one further second draw nozzle provided in the floor of the melt crucible, wherein the first draw nozzle and the second draw nozzle are disposed eccentrically to the center crucible axis and at a dist
