Problems solved by technology

[0013] However, this type of casting machine has very high component maintenance costs
In fact, in order to guarantee sufficient heat exchange, the rollers must be of considerable size, with high structural and maintenance costs

Embodiment Construction

[0036] With reference to the drawings, a thin slab casting apparatus generally indicated by reference numeral 100 comprises in a preferred but not exclusive configuration a mold 1 or casting apparatus provided with a crystallizer 2 configured To make the liquid metal introduced into the crystallizer 2 solidify.

[0037] The crystallizer 2 comprises two first walls 5, 6 having the configuration of plates facing each other and two second walls 7, 8 also having The plates facing each other and connected to the first walls 5, 6 are configured to together define a recess 17 containing the cast liquid metal.

[0038] The first walls 5, 6 substantially define the planar surface of the slab, while the second walls 7, 8 substantially define the thickness of the slab.

[0039] The width of the first walls 5 , 6 substantially corresponds to the width of the slab 18 , being much greater than the width of the second walls 7 , 8 . Merely by way of example, the width of the first wall 5 , ...

Abstract

The device for casting thin slabs consists of a crystallizer with two curved mobile walls (5, 6) made of material with a good heat conductivity, cooled and opposite the casting plane (Z), and two fixed lateral walls (7, 8), perpendicular to the first, refractory so as to form a cross section with a funnel shape.

Description

technical field [0001] The invention relates to continuous casting installations, in particular for casting slabs of extremely limited thickness, for example comprised between 5 mm and 40 mm. Background technique [0002] In the steel industry, a cast product with a parallelepiped geometry and width over thickness is identified by the term "slab". [0003] Currently, the state-of-the-art in casting installations is represented by two different machine families: continuous casting, where the crystallizer is mounted on an oscillating table with adjacent cooling plates, and twin-roll belt casting machines. One such twin roll belt casting machine is described in patent US-A-2016 / 023268. [0004] The first type of casting machine consists of a vertical oscillating mold consisting of plates made of a material of high thermal conductivity, cooled by cooling means, such as tubes made of the thickness of the plates, to remove heat from the molten metal, passing it through crystalli...
