Embodiment Construction

[0019] exist figure 1 A ladle 1 can be seen in it, which is basically constructed in a conventional manner and has a wall 2 . exist figure 2 The structure of the wall 2 is shown in detail in .

[0020] Correspondingly, the wall 2 is embodied in three layers. The layer 5 facing the hot inner side 7 is made of a refractory material. The layer 6 facing the outer side 8 is a metal casing. There is a liner in between, which forms layer 4 .

[0021] As can be seen, measuring elements in the form of optical waveguides 3 are introduced into corresponding holes or channels in the lining 4 . It is important here that there is good contact between the optical waveguide 3 and the lining 4 so that a good heat transfer can take place.

[0022] The optical waveguide 3 is made of a basic fiber (Grundfaser), which has different thicknesses depending on the measuring method used. The fiber Bragg method requires relatively thin optical waveguides (single-mode fibers) with a core diamete...

Abstract

The invention relates to a foundry ladle or an intermediate vessel (1) for receiving a liquid metal for further processing of said liquid metal, wherein at least a part of the wall (2) of the foundry ladle or of the intermediate vessel (1) comprises at least one measuring element (3) for detecting the temperature and / or the mechanical load. In order to be able to detect the temperatures and / or the mechanical load in the wall of the foundry ladle or in the intermediate vessel precisely, quickly and along the extension of the wall, according to the invention the measuring element (3) comprises at least one optical waveguide which is integrated in the wall (2) of the foundry ladle or of the intermediate vessel (1).

Description

technical field [0001] The invention relates to a ladle or intermediate vessel for containing liquid metal for its further processing, wherein at least a part of the wall of the ladle or intermediate vessel has at least one measuring element for mechanical loads . Background technique [0002] Metallurgical installations with heating elements having a high energy density, such as melting furnaces, are usually provided with temperature monitoring elements, with which it can be monitored whether the thermal load on the walls of the furnace is too high. For this purpose, furnaces are usually provided with cooling systems, as shown for example in document EP 1 600 717 B1. The electric furnace described here is equipped with a water cooling system, that is to say a cavity is arranged between the hot side and the cold side, through which cooling water can flow. [0003] As described in document WO 2004 / 015349 A2, an optical waveguide can be used to monitor a furnace. In this c...
