Abstract

The invention discloses a production method of microalloyed tin bronze alloy. The production method of the microalloyed tin bronze alloy includes the steps of firstly, subjecting alloy to smelting, thermal insulation, degassing, deslagging and refining in a smelting furnace; secondly, adding refiner to refined melt for microalloying; thirdly, performing alloy casting, namely subjecting the microalloyed melt to ingot casting; and fourthly, performing cold rolling and cogging, namely subjecting the alloy subjected to alloy casting to cold rolling so as to obtain deformed tin bronze alloy. Casting grain of the microalloyed tin bronze alloy produced by the production method is small in size, segregation degree of Sn in the alloy can be lowered, brittle cracking in rolling can be eliminated, and the alloy is highly plastic. Especially, the microalloyed castings can be directly subjected to cold rolling, and accordingly a homogenizing step in the existing production method is omitted, energy resources are economized, process flow is shortened, production efficiency is improved, and production cost is reduced.
