JPS574363A - Method for changing guide device for continuously cast ingot - Google Patents

Abstract

PURPOSE: To interchange ingot guide devices properly, quickly and easily according to casting sizes by guding each of plural dummy bars or plural ingots to the ingot support bodies which run curved or crooked respectively and independently.

CONSTITUTION: An ingot guide device stand 1 paralled in one piece with flask type frames 2 is placed freely slidably on a guide bed 4. The bed 4 is provided in the direcion intersecting perpendicularly with the casting line. Uppwer, lower guide roll paris 5 and side guide roll pairs 6 which guide, for example, two pieces of cast ingots are disposed to one frame 2 in a manner as to form ingot passage areas A, respectively. Upper, lower guide roll pairs 7 and side roll pairs 8 which differ in casting center, casting section and the number of casting pieces from the above- described upper, lower roll pairs 5 are mounted to the other frame 2 in a manner as to form ingot passage areas B, respectively. To change the previous pass to the pass of this time for the purpose of composite multipiece casting, the passage areas A or B are matched to or deviated from the casting line by moving the stand 1 forward and backward in the direction intersecting perpendicularly with, for example, the casting line, whereby the guide system for multipieces of ingots is changed at one time.
