Tom qab annealing thiab txias ntawm tin bronze tooj liab qhov chaw, qhov nruab nrab nyias pob tshab zaj duab xis uas tsis tev tawm tuaj yeem tsim rau ntawm cov hlau nto, kom tooj liab thiab tooj liab alloys muaj kev tiv thaiv zoo -discoloration thiab anti- oxidation muaj peev xwm. Qhov nruab nrab annealing yog ua kom cov ntsiab lus nyob rau hauv lub alloy diffuse nyob rau hauv ib tug khoom lub xeev kom txo tau lub unevenness ntawm cov tshuaj muaj pes tsawg leeg, feem ntau yuav txo tau cov unevenness ntawm tshuaj muaj pes tsawg leeg nyob rau hauv lub grain txheem. Yog vim li cas vim li cas qhov nruab nrab annealing kub yog li ntawd yog kom ceev lub diffusion ntawm alloying ntsiab thiab shorten lub sij hawm tuav kom ntau li ntau tau.
One of the most important process parameters for annealing is the maximum heating temperature. The choice of annealing heating temperature for most alloys is based on the phase diagram of the alloy system. The average annealing temperature for non{{0}}ferrous alloy ingots is generally "0.95solidus temperature (K)". The average annealing has high heating temperature and long holding time, so the thermal energy consumption is large. The annealing temperature of various non-ferrous alloys is a certain temperature below the solidus temperature of each alloy, above or below the solidus temperature.
Qhov nruab nrab annealing kub ntawm lub tes tsho tooj yog ntau dua li ntawm Ac3, feem ntau yog 1050-1200 degree. Lub ingot los yog casting yog rhuab mus rau ib tug ntau dua kub hauv qab lub solidus kub ntawm txhua alloy, khaws cia rau ib ntev lub sij hawm, thiab ces maj mam txias. Ib txoj kev annealing siv rau ingots los yog castings ntawm tin bronze, silicon bronze, thiab txhuas bronze.
