[Prior art] Conventionally, a molten metal container generally has 2 or It is lined with three layers. From the side of the shell, bricks or castables made of high quality or medium alumina are used as materials for protecting the steel skin, inside of which bricks made of low stone or medium alumina are lined, and silcon is used as the lining that comes into direct contact with the molten metal. quality, high alumina, spinel (MgO Al

There are drawbacks such as deterioration.

It is generally known that the infiltration of molten slack can be reduced by adding CaO to a 5% compound, and the CaO source is added to the malix part as alumina cement 1. General. However, the current situation is that when the amount of CaO added is increased, the corrosion resistance of the resulting lining material decreases rapidly.4 Therefore, the purpose of the present invention is to prevent pill-up without drastically reducing the corrosion resistance. The purpose of the present invention is to provide a lining material for a molten metal container that can be used.

本発明を完成するに至った。[Means for Solving the Problems] As a result of intensive research to solve the above-mentioned problems, the present inventors have found that by adding CaO as particles instead of in the matrix, corrosion resistance is lower than before. We have discovered that it is possible to add CaO while suppressing the amount of slag, and that the above-mentioned pill-up of slag can be prevented by using a lining material to which CaO has been added in a molten metal container.
The present invention has now been completed.

く低下するためである。The alumina-lime talinka used as an aggregate in the lining material of the molten metal container of the present invention contains 5 to 12% by weight of CaO, the remainder is alumina, and the main composition is Ca0.6Aβ20.
3. Here, the CaO content is 5 to 1
The reason why it is specified as 2% by weight is that if it is less than 5% by weight, the effect will be small, and if it is more than 12% by weight, the corrosion resistance as an aggregate will be significantly reduced.

特に限定されるものではない。As for the particle size of the aggregate, if it becomes too small, the corrosion resistance will deteriorate, so it is preferable to use a particle size of 0.2+nm or more, but when the above-mentioned components are mixed alone in the lining material construction product. In some cases, it may be necessary to use a material with a smaller particle size, and the particle size is not particularly limited.
