[Industrial Application Field] The present invention relates to a material with excellent corrosion resistance against molten metal. [Prior Art] Generally, melting equipment for melting zinc is used for zinc refining, zinc alloy casting, galvanizing, etc. Further, as this type of melting apparatus, a submerged melting system, a bridge wall melting system, etc. are known. These systems are configured so that molten zinc circulates within the tank while maintaining a uniform temperature, and various parts within the system such as the pump, thermoelectric protection tube, roller bearing, and steel plate for the plate holder. will come into contact with or be immersed in molten zinc. On the other hand, it is known that metal parts that come into contact with and are immersed in molten zinc are corroded by the molten zinc. In order to prevent corrosion caused by molten zinc, it has been proposed, for example, to form the pump from carbon, form the thermocouple protection tube and roller bearing from ceramic, and apply ceramic coating to the steel plate. Furthermore, it has been proposed that parts of such a melting device be made of an alloy of molybdenum (Mo) and tungsten (W), which are heat-resistant and hard materials. This kind of conventional alloy is 70% by weight
It has a chemical composition of Mo and the balance is W, and is produced by a melting method using a vacuum arc furnace. [Problems to be solved by the invention] However, although ceramics and carbon are excellent heat-resistant materials, they have low mechanical strength, poor impact resistance, and poor abrasion resistance, and melting equipment parts made of these materials cannot be used. has the disadvantage of short life. This increases the cost of the parts and therefore the production cost of the product. In addition, metal materials with high mechanical strength are generally unsuitable as materials for melting equipment because they are severely corroded by molten zinc, and only the alloys of Mo and W mentioned above are commercially available as materials for melting equipment and parts. It's just that. However, commercially available
Alloy materials of Mo and W exhibit better corrosion resistance against molten zinc than other metal materials, but their corrosion resistance is lower than that of ceramics and carbon, so commercially available alloy materials of Mo and W It is difficult to use it in place of ceramics, etc. The present invention was made in view of the above-mentioned drawbacks, and an object of the present invention is to provide a material having high mechanical strength and extremely excellent corrosion resistance against molten zinc. [Means for Solving the Problems] According to the present invention, there is provided a corrosion-resistant material characterized by being formed of an alloy having a chemical composition of 60 to 5% by weight of Mo and the balance being W. can get. The corrosion-resistant material according to the invention can be used as a part that is immersed in molten metal and is shaped by powder metallurgy in the form of a sintered material or in the form of a plastically worked material. [Function] The corrosion-resistant material in the present invention is made of an alloy of Mo and W, which have very high melting points of about 2600°C and about 3400°C, respectively. The melting point of this alloy is approximately proportional to its chemical composition.
It has a melting point between 2600°C and 3600°C, so it has extremely high heat resistance. The sintered material obtained by sintering the material made of this alloy can be produced by varying the proportions of Mo and W within the chemical composition range of 60 to 5% by weight of Mo and the balance W. , tensile strength 28 (Kgf/mm 2 )
It increases from 38 (Kgf/mm 2 ) to 38 (Kgf/mm 2 ). Furthermore, it was confirmed that when the sintered material having the above composition was immersed in molten zinc, the weight loss rate was 0 (g/m 2 hr).
On the other hand, when the chemical composition of the sintered material other than the above is 70% by weight or more, the weight loss rate becomes higher than 2.00 (g/m 2 hr) as the proportion of Mo increases, and the sintered material made of pure tungsten Weight loss rate is 0.05
(g/m 2 hr). In any case, Mo60~
It has been found that an alloy with a chemical composition of 5% by weight balance W has excellent corrosion resistance. In addition, in the case of a rolled material formed by rolling, if the composition is Mo60 to 5% by weight balance W, as the proportion of W increases, the tensile strength increases to 100 (Kgf/
mm 2 ) to 140 (Kgf/mm 2 ). Further, when immersed in molten zinc like the sintered material, the weight loss rate of the rolled material within the above composition range was 0 to 0.01 (g/m 2 hr). On the other hand, for rolled materials outside the above composition range, for example, rolled materials containing 70% by weight or more of Mo, the raw material speed is 0.105 (g/m 2
hr). Therefore, sintered and rolled materials made of alloys with a chemical composition of Mo60 to 5% by weight with the balance being W increase the heat resistance of melting equipment parts in actual molten zinc.
Helps increase mechanical strength and improve corrosion resistance. [Example] Next, an example of the present invention will be described with reference to the drawings. Example 1 The corrosion-resistant material according to Example 1 of the present invention is Mo-
It is formed from a sintered material made of W alloy. In this case, first, tungsten powder with an average particle size of about 2 μm and molybdenum powder with an average particle size of about 4 μm are weighed so that the chemical composition of Mo is 5, 20, 25, 30, 50, and 60% by weight, and then used in a V-type mixer. Mixed. After that, about 3 tons/
cm 2 by mold press, and the resulting plate-shaped compact was sintered at approximately 1800°C in a high-purity hydrogen atmosphere for 30 hours to obtain an ingot with a thickness of 15 mm as a sintered material. . The mechanical strength and corrosion resistance of this sintered material were examined as follows. Regarding mechanical strength, the tensile test of the above sintered material was conducted in accordance with JIS B-7702 (JIS Z
-2201), and the tensile strength and elongation of each test piece were measured. Also,
Corrosion resistance depends on the conditions in which actual zinc melting equipment parts, such as pumps, are placed, i.e. temperature.
Cd (cadmium) 0.10% by weight, Pb at 695±10℃
The entire surface of the sintered material test piece was immersed for 506 hours in a molten metal containing 14 ppm (lead) flowing at a constant rate of 2.7 mm/sec. Thereafter, the test piece taken out from the molten metal was washed with dilute sulfuric acid to dissolve the zinc adhering to the test piece. Then, the weight loss rate was determined from the difference in weight of the test piece before and after immersion in the molten metal, and was used as a measure of corrosion resistance. Table 1 shows the results of the tensile test and the corrosion resistance test. The Mo70, 75, 100, 0% by weight materials and hard graphite in the table are reference examples for comparison.

It is significantly improved within the composition range of Mo60 to 5% by weight balance W, and furthermore, within the above composition range, the sintered material has the same elongation as carbon, but shows 5 to 8 times the tensile strength. I understand that. Example 2 The corrosion-resistant material according to Example 2 of the present invention is Mo-
It is formed from a rolled material made of W alloy. In this case, the rolling mill receives approximately 900 to 900 ingots produced by the same sintering method as the ingot produced in Example 1.
It was obtained by hot rolling at 1500°C and finishing it into a 2 mm thick plate. The mechanical strength of this rolled material was determined by a tensile test using a JIS B-7702 test piece similar to that used in Example 1, and the corrosion resistance was determined by testing the molten metal at a temperature of 965°C ± 10°C as described above in the same manner as in Example 1. The weight loss rate was determined by dipping the entire surface of a specimen of the rolled material and measuring the weight difference.

することが可能である。[Table] As is clear from Table 2, as the weight percentage of Mo decreases, the mechanical strength of the rolled material increases. On the other hand, an alloy having a chemical composition of 60 to 5% by weight of Mo and the balance being W exhibited extremely excellent corrosion resistance against molten zinc, similar to the test results in Example 1. Moreover, it was found that it exhibited an elongation of 1% or more in a tensile test. The tensile strength of rolled materials with a chemical composition within the above composition range is 20 to 28 times that of carbon.
It was twice as hot. In FIG. 1, a curve 11 shows the relationship between the tensile strength of the sintered material and the Mo content, while a curve 12 shows the relationship between the tensile strength and the Mo content of the rolled material of Example 2. In addition, in FIG. 2, the relationship between the weight loss rate of the sintered material and the Mo content is shown by curve 13, and the relationship between the weight loss rate of the rolled material and the Mo content is shown by curve 14.
is shown. The weight loss rate is a factor that determines corrosion resistance, and the smaller the value of the weight loss rate, the better the corrosion resistance. Although materials manufactured using the powder metallurgy method, such as those manufactured using the electron beam or arc melting method, also have high mechanical strength,
Results showed excellent corrosion resistance. [Effect] As stated above, in the present invention, Mo60
If the alloy has a chemical composition of ~5% by weight and the balance is W, it is a sintered product manufactured by powder metallurgy or melting.
A corrosion-resistant material can be obtained that can be applied to ingots or all parts that have been plastically worked from ingots by forging, rolling, etc. This corrosion-resistant material has excellent corrosion resistance against molten zinc and also has excellent mechanical properties. Therefore, the life of parts of melting equipment for zinc refining, alloy casting, galvanizing, etc. is extended, and it is possible to reduce the production cost of metal products such as zinc.
