Abstract
1352815 Continuous casting; casting processes MITSUBISHI JUKOGYO KK 10 April 1972 [9 April 1971] 16474/72 Heading B3F A tube having internal and/or external longitudinal fins (the fins on the tube being either all spiral or all straight) is continuously cast with the use of a core 6 and mould 7 either or both being finned and the metal being provided by an electroslag arrangement, e.g. with consumable electrodes 5 of arcuate shape, Fig. 5(a), the molten metal being vibrated, as by vibrators 11 contacting a tubular starter 9. As shown in Fig. 6, the latter has internal spiral fins like those of a tube to be cast and with the cast tube it is rotated by a motor 16 and table 14 as a supportÀ ing plate 17 is lowered. If the fins are straight, withdrawal rolls extract the starter and casting. Cooling water passes to and from the mandrel 6 and mould 7 through pipes 8. At the start, molten slag 12 is retained in the tapered inlet of the cavity by the top of the starter 9 as shown. The top of the starter also melts when the metal melts. During casting, mushy slag forms a heatinsulating and lubricating layer between the metal and casting surfaces. The vibration of the metal facilitates filling of the casting cavity and imparts grain uniformity.
