Abstract:
A tubular mold having a top end that is positionally fixed in a water-tight manner within a watertank, comprising:a tube wall having a top front end, the tube wall having a circumferential recess adjacent the top front end, and an outer peripheral groove having a depth, the groove being located at a distance from the top front end and circumferential recess of the tube wall; a plurality of U-shaped flanges, the flanges having inner latching segments configured for gripping insertion into the peripheral groove, each of the inner latching segments having a radial extension smaller than the depth of the peripheral groove; and a reinforcement frame at least partly located in the circumferential recess, the frame being screw-couplable and adjacent to the U-shaped flanges and bracing against flanges of the water tank, the frame being locatable in position with an exact fit, while being sealed off from the tube wall, as well as from the flange of the water tank, wherein the tube wall is thereby stabilized against pressures exerted by cooling water.
