MANUFACTURING DEVICE OF COMPOSITE STEEL INGOT BY ELECTROSLAG REMELTING PROCESS

摘要

PURPOSE: To obtain a homogeneous composite steel ingot where the uniformity of the penetration at the boundary of a core material and an outer circumferential cladding by welding part is improved by synchronously rotating the core material and the mold by using a mechanical and electrical mechanism. ;CONSTITUTION: A transmission shaft 60 is rotated by the rotation of an electric motor 65, and the first and the second transmission gears 70, 72 are synchronously turned. One of the transmission gears is transmitted to the gear 23 which is fixedly provided to an inner cylinder 21 of a mold 20 to rotate the inner cylinder 21. The other is transmitted to a driving gear 81 to drive the stationary surface plate 2 for the core material, and the core material 1 is rotated together with the stationary surface plate 2 for the core material in a completely synchronous condition with the rotation of the inner cylinder 21 of the mold 20. Thus, since the rotation of the core material 1 and the rotational transmission to the mold 20 can be executed only through the mechanical transmission means and the mechanical transmission system consists of the transmission shaft 60 of the spline, a fixed transmission gear 72 mounted thereto, and a moving transmission gear 70, it is possible to securely execute synchronous rotation of the core material 1 and the mold 20 by using a simple constitution irrespective of the size of the device and to improve the uniformity of the penetration and the flow of the melting current.;COPYRIGHT: (C)1993,JPO&Japio
