Centrifugation device high-temperature alloy used for glass wool production

Abstract

The invention discloses centrifugation device high-temperature alloy used for glass wool production. The alloy comprises the following chemical components according to the weight percent: 0.65% to 0.75% of C, 28.5% to 30.5% of Cr, 4.0% to 6.5% of Co, 4.5% to 6.0% of W, 3.0% to 5.0% of Mo, 4.8% to 5.9% of Al, 2.0% to 3.0% of Ti, 0.01% to 0.05% of Ce, 0.01% to 0.05% of B and the balance of Ni. Because of unique formulation, the alloy obtains excellent high-temperature mechanical property, high-temperature corrosion-resisting property and high-temperature oxidation resistance property under the composite action of technical means of solid solution strengthening, precipitation strengthening, crystal boundary strengthening, and the like, and the service life is obviously enhanced.

Description

technical field [0001] The invention belongs to the field of high-temperature alloys, in particular to a nickel-based high-temperature alloy used in a centrifuge for glass wool production. Background technique [0002] The centrifuge is an indispensable key component in the centrifugal blowing glass wool production line. It needs to work under the high temperature of 960℃~1020℃ and the centrifugal force of 1900~2400rpm / min. Erosion and erosion. Therefore, the materials used in the manufacture of centrifuges for glass wool production must have excellent high-temperature mechanical properties, high-temperature corrosion resistance and good high-temperature oxidation resistance, so that the centrifuges made can operate normally in a long life No deformation, breakage. Generally speaking, cobalt-based superalloys can basically meet the above requirements, but as the main element cobalt in the material, it is a scarce element, the price is very expensive, and it is impossible t...

Problems solved by technology

Generally speaking, cobalt-based superalloys can basically meet the above requirements, but as the main element cobalt in the material, it is a scarce element, the price is very expensive, and it is impossible to apply it on a large scale in industry

At present, the centrifuge superalloy used in the production of glass wool has poor resistance to repeated impacts of high-temperature glass liquid, and its service life is very short. Its performance of high-temperature oxidation and corrosion resistance needs to be improved urgently.
