Definitions
- the present invention relates to an immersion nozzle for continuous production that is difficult to adhere to alumina, that is, a immersion nozzle for continuous production in which alumina is hardly adhered to a wall surface of an inner hole serving as a passage of molten steel by using a material containing CaO. It relates to a manufacturing method. Background art
- Japanese Patent Application Laid-Open No. 57-71860 describes that graphite and sintering power Lucia, electrofusion calcium, or Ca A production nozzle using a refractory obtained by combining other ceramic raw materials containing 0 component is disclosed. This is to prevent alumina from depositing by reacting alumina adhering to the inner wall surface of the nozzle with CaO in the brick to generate a low melt.
- Such C a O-containing refractories have shown a certain effect on the prevention of alumina adhesion, and in particular, C a O as a mineral phase such as potassium lucia clinker and potassium lucia-magnesia clinker including dolomite clinker. Contains ⁇ The effect of the refractory using clinker is excellent.
- a composition using clinker containing Ca ⁇ as a mineral phase was placed in the immersion nozzle, including the inner hole and main body, and a zirconia-graphite compound was used in the powder line. And molded integrally, and then fired in a reducing atmosphere to produce the compact.
- Japanese Patent Application Laid-Open Publication No. 2000-501-3944 states that adding a CaO-containing powder to the zirconia-graphitic compound in the powder line allows each part to be treated.
- a proposal has been disclosed which attempts to eliminate the occurrence of cracks by making the expansion behavior the same.
- a CaO-containing powder is added to the zirconium / graphite blend, there is a problem that the corrosion resistance is reduced and the durability of the powder line portion, which is the application site, is reduced. DISCLOSURE OF THE INVENTION.
- a zirconia-graphitic compound is arranged in a powder line portion, and a clinker containing Ca0 as a mineral phase is used in at least an inner pore portion to prevent adhesion of alumina.
- An object of the present invention is to provide a method of manufacturing an immersion nozzle in which articles are arranged and integrally molded, and the molded body is fired in a reducing atmosphere, in which cracks generated during the firing are prevented.
- the present invention provides a clinker containing Ca ⁇ as a mineral phase by performing a hydration prevention treatment on the volume expansion during firing, which is one of the causes of crack generation in the above-described manufacturing process. This has been completed based on the finding that by suppressing the digestion reaction between water released from the resin and C a O, the occurrence of fire cracks can be prevented. That is, the present invention provides a immersion nozzle for continuous production in which a zirconium-graphitic refractory is applied to a powder line portion, and at least a hydrated surface of particles containing CaO as a mineral phase in at least an inner pore portion.
- a body containing the clinker having been subjected to the preventive treatment in an amount of 10% by mass or more and a main body are integrally formed.
- a specific method for preventing hydration of clinker containing Ca ⁇ as a mineral phase a method of converting CaO exposed on the surface of clinker into a stable compound that does not react with water and a method of entirely clinker There is a method of coating with a film through which moisture does not easily pass.
- the former method for example, there is a technique of the C A_ ⁇ stable compound, such as C a COC a SOC a 3 ( P 0 4) 2.
- C a COC a SOC a 3 P 0 4
- && (3 & O 3) there is a method in which untreated clinker is heat-treated at about 300 to 850 ° C in a CO 2 atmosphere.
- a coating with a coating such as a heat-resistant resin such as a silicone resin, a pitch, and a water-permeable coating such as magnesium sulfate.
- the treatment of C a O exposed on the clinker surface as C a C O 3 affects the processing cost, hydration prevention ability, and quality of refractory after firing. And is preferred.
- This hydration prevention treatment is preferably applied to all the clinkers contained in the refractory composition, but even in some cases, the effect is exerted depending on the degree of the treatment.
- C a O and C a Z r 0 3 clinker which is not present, C a O ⁇ S I_ ⁇ 2 Clean force first and other C a O system as mineral phases in the clinker containing C a O It may be a material mainly composed of a compound, or an arbitrarily added oxide, carbide, carbon or the like.
- the mineral phase in all formulations is 10% by mass or more, preferably 20% by mass or more, and more preferably 30% by mass or more. Further, the main body portion can be handled by using a commonly used material.
- FIG. 1 is a diagram schematically showing a cross section of a dolomite clinker subjected to a hydration prevention treatment applied to the present invention.
- Zirconia / graphite materials were placed in the powder line section, CIP-molded under a molding pressure of 1000 KgZcm 2 according to each formulation example, reduction firing was performed at a firing temperature of 1000 T, and the state of cracking after firing was observed.
- each 4-6 is Karushiakurin force one, whether C_ ⁇ 2 process to dolomite clinker.
- All of the dolomite clinkers of the examples shown as the present inventions 1 to 3 are clinkers which have been subjected to a heat treatment in a CO 2 atmosphere and subjected to a hydration preventing treatment.
- Dolomite clinker shown in Comparative Examples 1 to 3 is a general clinker not subjected to a surface hydration preventing treatment.
- the portion other than the powder line portion is a clinker containing CaO as a mineral phase, and is composed of a mixture obtained by adding an appropriate amount of phenolic resin to the raw materials shown in the table and uniformly kneading.
- the zirconia graphite material is composed of 90% by mass of zirconia and 10% by mass of graphite to which an appropriate amount of phenol resin is added and uniformly kneaded, and is common to all nozzles in Table 1.
- FIG. 1 is a diagram schematically showing a cross section of the dolomite clicker subjected to the hydration prevention treatment shown in Table 1 of the present invention, wherein the C a O exposed on the surface of the clinker containing C a O is shown. the indicating the state of being covered by the processing method of the C a C 0 3.
- Examples 1 to 3 of the present invention in Table 1 cracks during firing could be prevented by using clinker subjected to hydration prevention treatment, whereas Comparative Examples 1 to 3 were all Lateral cracks occurred at the boundary between zirconium and graphite.
