Embodiment Construction

[0047] The invention is further illustrated by the following examples.

[0048] The embodiment relates to a formulation based on iron-poor sintered magnesia obtained from iron-poor and lime-poor magnesite.

[0049] The sintered magnesia used in the examples has the following composition according to Table 1, wherein the data in the right column (based on the ratio of each oxide to the total weight of the sintered magnesia) are data expressed in% by weight, respectively.

[0050] Oxide proportion MgO94.4 Fe 2 O 3 0.6 SiO 2 2.2 Al 2 O 3 0.1 CaO2.7

[0051] Table 1.

[0052] Three batching examples A, B and C based on the batching of sintered magnesia according to Table 1 for the present invention are given in Table 2 below, where the data in the batching column (based on the proportion of each component in each batching The ratio of the total weight) is the data expressed in weight %.

Abstract

The invention relates to a refractory ceramic batch composition for producing an unshaped refractory ceramic product; to the use of a batch composition of this type for lining metallurgical melting vessels; and to a metallurgical melting vessel lined with an unshaped refractory ceramic product based on a batch composition of this type.

Description

Technical field [0001] The present invention relates to refractory ceramic ingredients for the preparation of unshaped refractory ceramic products (Erzeugnisses), the use of such ingredients for the lining of metallurgical smelting vessels (Schmelzgefäßen) and the metallurgical smelting vessel, said smelting vessel being lined with Unshaped refractory ceramic products with a variety of ingredients. Background technique [0002] Refractory ceramic ingredients are well known to refer to a composition composed of one or more components, from which refractory ceramic products can be prepared by means of ceramic firing. The term "refractory ceramic products" in the meaning of the present invention especially refers to ceramic products with an application temperature above 600°C and preferably refractory materials according to DIN 51060, that is to say, the temperature cone equivalent> Material of SK17. The determination of the temperature cone equivalent can be carried out in part...
