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 &ldquo;large walls&rdquo;, are each held against a reinforcing backplate ( ) to which it is rigidly fastened by a clamp ( ), the shape of which is elongate in the width direction of the large wall and which goes over the top of the large wall and its associated backplate.

Mold or wide cross section for the hot-top vertical continuous casting of metals

In this type of mold, a feed head (,) made of thermally insulating refractory fits on top of the cooled copper crystallizer (,) being internally aligned with it in order to define a passage for the cast metal, with interposition between the two of an insert (,) made of dense refractory having mechanical strength properties. This insert (,) consists of bars, each bar (,) being formed by a rigid assembly of aligned and juxtaposed contiguous elements (,) kept clamped against each other by a clamp incorporated into the bar, such as a cross-tie (,) associated with compression pads (,), and positioning and aligning the bar on the crystallizer (,) are provided and consist of a battery of spring pushers (,), which battery is associated with a positioning stop (,) on the crystallizer against which the bar (,) presses.

The continuous casting installation includes an ingot mould the walls (,) of which are formed by cooled metal walls (,) surmounted by a hot-top element (,) made of a heat insulating material. Holes for injecting a gas under pressure, such as a slot (,), lead into the ingot mould at least at the interface between the hot-top element and the metal wall. The insulation includes means (,to,), connected to the said holes, for supplying a gas or a gaseous mix with a thermal expansion capacity adjustable according to the composition of the cast metal alloy and the casting conditions. The adjustment of the thermal expansion capacity of the injected gas enables the adjustment of the heat flux density extracted from the cast metal in the zone where it starts to solidify.

A continuous casting mold for metals is provided that is formed of an assembly of four metallic plates (13, 14) which plates have channels in their respective interiors. The channels are vertically oriented and serve to pass a fluid which is being circulated for the purpose of cooling. Two or more of said plates (13, 14) each have one or more horizontal channels (6a, 6b) in the upper part of the plate, which channels serve for circulation of cooling fluid and are independent of the aforesaid vertical channels, wherewith the said vertical channels are terminated at a level below said upper part of the plate.

The subject of the invention is a method of lubricating a mold (1) for the continuous casting of a metal product (16), of the type including a vigorously-cooled vertically-oscillating metal tubular element (2) defining a passage (4) for the cast metal and intended to cause, in contact with its wall (3) in said passage, the solidification of said metal product, in which a lubricant in the liquid state is injected through said metal tubular element toward said metal product being solidified, wherein said injection is carried out at points distributed annularly at a single level of said tubular element, said level lying at a distance greater than 20 cm from the lowest level at which solidification of said product is able to be initiated, and in that the flow rate of said lubricant is sufficient to cause a fraction of said lubricant to rise up along said wall to the level at which solidification of said product is effectively initiated.

According to the invention, molten metal 3 is poured into a continuous-casting ingot mold and the thickness of the product 1 emerging from the ingot mold is reduced using a device for reducing the thickness 20, while the core 5 of said product has still not solidified. The thickness of the product 1 is reduced only in a central zone, excluding the solidified edges of the product, using means for reducing the thickness such as rolls 22 whose working length is less than the width of the large faces 11 of the ingot mold. Means 8 are provided downstream of the rolls 22 in order to crop the edges 7' of the product in the manufacture of thin slabs 9.
