Embodiment Construction

[0078] Figure 1 shows a base with two layers, namely a lower layer 10 and an upper layer 20 arranged on top. Both of them are approximately circular in top view (plan view).

[0079] The lower layer 10 is designed as a permanent lining and is made of a refractory ceramic mass based on alumina. The permanent lining 10 is entirely designed as a prefabricated element and features a horizontal lower surface 10u and a three-dimensionally designed upper surface 10o. Surface 10o is characterized by the following regions:

[0080] - about the first rung 13 in the center;

[0081] - raised impact pad 14 in the upper left third;

[0082] All areas of the surface 10 o are inclined at approximately 3° relative to the horizontal, with a slope in the direction towards the discharge area 30 .

[0083] The upper layer 20 , so the wear layer, consists mainly of (>80M.-%) cubic refractory bricks 21 of the same size and uniform layout (except in the area of ​​the discharge opening 30 ).

Abstract

The floor has a base that includes a lower layer of a refractory ceramic outer lining and a top layer of a refractory ceramic wearing lining (20). The outer lining has an upper surface (20o) with a three-dimensional design which is partially inclined to a horizontal by more than one adjacent to the wearing lining. The wearing lining consists of a refractory ceramic solid brick (21). The outer lining and the wearing lining include an interruption for forming a common outlet for a high-temperature melt.

Description

technical field [0001] The invention relates to a refractory ceramic base (bottom) in the region of the connection to at least one wall of a vessel for handling a high-temperature melt. Background technique [0002] The container may be, for example, a metallurgical bucket. This application is used below to further describe the prior art and the present invention. [0003] Such a bucket is shown eg in US 5.879.616 A. Very simply put, the scoop consists of a base and a wall extending upwards from the base, the scoop having an almost circular internal cross-section so that overall a tank shape results. At least one hole (drain area) is arranged in the base. [0004] The molten metal carried in the bucket enters a downstream device, such as a tundish, through a discharge port (tap). In order to adjust / control the amount of molten metal, there are for example stoppers or sliding plate valves, which are also called control devices. [0005] If slag also gets into the tundish...
