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

The invention concerns an ingot mould comprising in succession, in the direction for extracting the metallic product to be cast ( ): a preheater ( ) made of noncooled refractory material acting as reservoir for the melting metal to be cast and a standard cooled tubular metal element ( ) for solidifying the metal. A slot ( ) for injecting the shearing gas (for example Ar) is arranged between the preheater ( ) and the metal clement ( ) so as to emerge on the ingot mold internal periphery. The injection slot comprises means ( ) for reducing the gas flow in each of the ingot mold angles, preferably formed by obstructing elements. The invention enables to reduce, even eliminate, defects encountered along the edges of the solidified cast products.

Ingot mould with multiple angles for loaded continuous casting of metallurgical product

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.

Mould head for the vertical hot-top continuous casting of metal products elongate cross section

The invention concerns the adjustment of the linear distribution of an injected shearing fluid, during casting, through a slot (,) provided in the cooled metal body (,)&mdash;refractory riser block (,) interface of an ingot mold for continuous metal casting charge and emerging along said ingot inner periphery, the latter being provided with clamping means for adjusting the slot thickness. The invention is characterized in that it consists in &ldquo;cold&rdquo; injecting through said slot (,) a regulating inflammable fluid, which is ignited on its exit from the slot, and in acting on the clamping means (,) such that the height of the flames (,) coming out of the slot (,) is substantially constant along the whole ingot inner periphery. The invention provides the advantage of an accurate and lasting adjustment of the injected flow rate without requiring the adjustment of the injection slot thickness. The invention is applicable to continuous steel charge casting in particular.

Method and device for continuous metal charge casting

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.
