Example Embodiment

[0016] A high temperature resistant valve material. The high temperature resistant valve material is composed of the following components in a weight ratio: 1-10 parts of yttrium, 10-20 parts of niobium, 20-30 parts of carbon steel, 12-22 parts of shell powder, 10-20 parts for steel and 1-10 parts for activated carbon.

[0017] Preferably, the content of each component is: 2-8 parts of yttrium, 12-18 parts of niobium, 22-28 parts of carbon steel, 13-20 parts of shell powder, 12-18 parts of steel, 2-8 parts of activated carbon.

[0018] Preferably, the content of each component is: 4-6 parts of yttrium, 14-16 parts of niobium, 24-26 parts of carbon steel, 15-18 parts of shell powder, 14-16 parts of steel, 4-6 parts of activated carbon.

[0019] A method for preparing a mold using the above-mentioned high temperature resistant valve material includes the following steps:

[0020] (1) Grind niobium, carbon steel and steel into powder, and then put it into a container;

[0021] (2) Stir ...

Abstract

The invention discloses a high-temperature-resistant valve material and a preparation method thereof. The high-temperature-resistant valve material is prepared from components in weight ratio as follows: 1-10 parts of yttrium, 10-20 parts of niobium, 20-30 parts of carbon steel, 12-22 parts of shell powder, 10-20 parts of steel and 1-10 parts of activated carbon. The method for preparing a die from the high-temperature-resistant valve material comprises the following steps: (1), niobium, the carbon steel and the steel are ground into powder and the powder is placed in a container; (2), the powder in the container is stirred for 30-50 min and then is heated to 300-350 DEG C, and the heat is preserved for 40-60 min; (3), stirring is performed again, yttrium, the shell powder and the activated carbon are sequentially added, the mixture is heated again to reach 400-450 DEG C, and the heat is preserved for 30-50 min; and (4), cooling is performed for 80-120 min, the temperature is reduced to 100-150 DEG C, stirring is performed again finally, and a product waits for cooling shaping finally. The produced high-temperature-resistant valve material has the advantages of being healthier andharmless to a human body.

Description

technical field [0001] The invention relates to the field of mechanical materials, in particular to a high temperature resistant valve material and a preparation method thereof. Background technique [0002] Existing high-temperature-resistant valve materials have average performance, complex and cumbersome proportioning, and high cost, which greatly increases the cost required for production, resulting in reduced profits and increased market prices, which do not meet actual production requirements. [0003] Existing high temperature resistant valve materials often contain substances harmful to human health. Contents of the invention [0004] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a healthier, more cost-effective, high-temperature-resistant valve material with simple proportioning and a preparation method thereof. [0005] Technical solution: In order to solve the above technical problems, the prese...
