Abstract

The invention discloses a gas compressor bearing block of a gas turbine. The gas compressor bearing block comprises a metal body made of an alloy material. The alloy material is prepared from 1-2% of B, 0.7% of As, 1.4% of Ta, 0.5% of Ra, 1.1% of K, 1.3% of Zn and the balance Fe and inevitable impurities. The alloy material is prepared through the following steps that firstly, Fe, B, Fe-As alloy and Fe-Ta alloy are melted under the protective atmosphere; secondly, the temperature is adjusted to be 950 DEG C, Fe-Ra alloy, Fe-K alloy and Fe-Zn alloy are added in a melt and stirred evenly, and heat preservation standing is carried out for 25 min; thirdly, argon is introduced, the melt is subjected to standing, cooled to 650 DEG C and subjected to die casting, and the alloy material is obtained. The gas compressor bearing block of the gas turbine is high in strength, excellent in corrosion resistance, heat resistance and other performance and capable of being used for a long term.
