Problems solved by technology

However, during casting, in other words, when "heating", it causes a wavy deformation of the copper plates between the connections
Undoubtedly, such deformations of up to a few tenths of a mm are of little concern in normal continuous casting, but are completely unacceptable in hot-top continuous winding casting, because such deformations can cause the copper plate to separate from the Misalignment occurs within the mating plane between the refractory feed ports, specifically at the location where the first shell of solidified cast metal is formed

Embodiment Construction

[0016] refer to figure 1 , it can be seen that the top of the machine for vertical hot-top continuous casting of slabs is in a known manner along the direction of extraction of the cast metal given by the arrow F arranged on the casting axis A (i.e. in the drawing from top down) with: a funnel 1 containing molten metal 2 which conveys the molten metal through a dark nozzle 4 on each mold and side outlets 5 for the metal to a A mold 3 (or in general several molds 3), said outlet is located about 10 cm below the free surface 6 of the liquid metal in the mould. The mold generally comprises two superimposed worktables 7 and 8, which have corresponding independent but complementary functions.

[0017] The lower table 7 constitutes the main part of the mold - the mold - and the thermally active parts 9 of this part have the basic function of imparting a certain degree of stability to the cast metal in such a way that the mechanical strength of the casting skin is sufficient to prev...

Abstract

A mold for hot-top vertical continuous casting of metals includes a feed head made of a thermally insulating refractory material which surmounts a cooled copper crystallizer and is internally aligned with a cooled copper element of the cooled copper crystallizer in order to define a calibrating passage for the cast metal. The copper element is formed by an assembly of plates, some of which, termed ''large walls'', are each held against a reinforcing backplate. The front of each large wall has a crossette, which retracts relative to above passage so that it can connect to the claw of the clamp for adjusting the holding force between said plate and the backplate on the clamp. The crossette provides a space for holding infusible feed inlet.

Description

technical field [0001] This invention relates to hot top continuous casting of metals, in particular steel. In particular, the present invention relates to hot-top casting of semi-finished metals having elongated shapes, such as slabs, thin slabs, etc. casting. Background technique [0002] We recall that the wide-section mold was first a bottomless metal tube, set vertically, within which the cast steel solidified in contact with the inner walls, effectively cooled by the vigorous circulation of water. Such a tubular part is usually made of copper or more specifically a copper alloy and has a typical height of about one meter. However, this part differs from other types of continuous casting moulds, mainly in that it is not monolithic but consists of four plates connected together at right angles, a pair of large plates and a pair of Small side panels, said pair of large panels facing each other and forming a large surface of the slab, generally much greater than one met...
