られる。Blast furnace slag is a by-product of steel production, and has advantages such as low raw material cost and stable production because it is produced in large quantities. However, when manufacturing colored rocks used for applications such as building materials from blast furnace slag, first, it is possible to give a desired color of cold color or warm color, and secondly, it is moistened (glossy) with crystalline rock. It is required that the stone quality be given, and thirdly that the manufacturing cost and the raw material cost be as low as possible.

いる。However, if the blast furnace slag is simply melted and solidified as a main raw material, a black solidified product is produced, and even if a coloring material is added, the black color hinders a desired color from being obtained. Therefore, various attempts have been made in the past so that artificial stones of a desired color can be produced using blast furnace slag as a main raw material.In recent years, feldspar, alumina, and chromium oxide have been added to and mixed with blast furnace slag. It has been confirmed that a warm-colored artificial stone can be manufactured by melting in a swirling melting furnace in which an oxidizing atmosphere is secured.

It has been confirmed that a warm color artificial stone can be produced by melting a mixture of 20 parts by weight of feldspar, 40 parts by weight of alumina, and 0.3 parts by weight of chromium oxide in a swirling melting furnace under an oxidizing atmosphere.

In the range surrounded by A, B, C and D in FIG. 1, the melting is performed under oxidizing conditions and the cooling is 1100.

It contains O 2 , CaO, Al 2 O 3, etc., and these three components account for 90% by weight of all components. Further, feldspar has SiO 2 as a main component, and quick lime has CaO as a main component. These feldspars and quicklime are designed to give luster to warm-colored artificial stones by adjusting the basicity (CaO / SiO 2 ) in the raw materials.
In addition, alumina (Al 2 O 3 ) and chromium oxide (Cr 2 O 3
3 ) is for developing a warm color system. The tint of coloring of the warm-colored artificial stone can be changed by the addition amount of the warm-colored colorant, and when chromium oxide (Cr 2 O 3 ) is used as the warm-colored colorant, α-Al 2 O 3 By substituting a part of Cr with Cr, a color develops pink or wine red.

In addition to the three components of O 2 , CaO and Al 2 O 3 , MgO, MnO, TiO 2 , Fe 2 O 3 , SO 3 and the like are contained as minor components. SO 3 is contained in about 1% by weight,
Most or part is present as sulfur (S). This sulfur reacts with a metal oxide added as a warm colorant or a metal oxide contained in the blast furnace slag to form a black sulfide, or a metal oxide effective for good color development. Since it is consumed, it hinders the production of the target warm-colored artificial stone. Therefore, paying attention to the fact that sulfur easily burns in the air to become sulfur dioxide, in order to remove sulfur as sulfur dioxide by directly heating and melting the raw material in the air atmosphere (oxidizing condition). is there.

For melting, a method of blowing fossil fuel or plasma flame, or heating and melting the raw material by irradiation of electromagnetic waves, and supplying sufficient air to the melting portion at the same time as heating may be adopted. A method of burning a sulfur component with a flame while imparting a turning force to the above may be adopted.

The reason for cooling at a cooling rate of in or less (preferably 15 ° C / min or less) is 20 ° C / m between 1100 and 900 ° C.
This is because when cooled at a cooling rate exceeding in, crystals of α-Al 2 O 3 are hard to precipitate and vitrify.
