Wok bilong 'annealing furnace' em long hatim wok i go long wanpela temperaja ol i bin makim pinis na long hatim metal bihain long wanpela haptaim bilong.
Ol ditel i olsem:
1. Impruvum o karemaot ol difren strakja defek mo residual stres we i kamaot from steel long taem blong kasting, forging, roling mo welding blong blokem defomesen mo kreking blong ol wokpis.
2. Softenim wokpis long katim.
3. Rifainim grein na kamapim gut straksa bilong kamapim gut ol mekanik samting bilong wokpis.
4. Redim straksa bilong fainel hat tritmen (kinking, tempering).
As tingting bilong wok bilong mekim wok:
Long rot bilong sirkulasen bilong fan, tempereja distribusen long furnace rum bilong annealing furnace i wankain, na tupela oven rum bilong annealing furnace i ken wok indipenden, we i mekim gutpela wok bilong annealing i wok gut{{0} i gat tupela fan i stap insait long wan wan oven rum, tasol i no gat ea filta i stap insait long fur situesen {2} Em i narapela kain long fur situesen i stap insait long fur situesen. saiklon, na maikrostraksa bilong ol samting bilong piksa i kamap gen long rot bilong hat tritmen, na long dispela rot ol i stretim gut stebiliti na konvesen efisiens. Ol kasting i hat long samting olsem 950 digri na bihain ol i kol inap long wanpela haptaim bilong daunim hevi insait long ol ain kasting na weldim hap. Taim ol i hatim 200 digri , na bihain long ol i hatim ain, em i save kamap long ol tempereja long temperaja, na bihain ol i save hatim austenite i save kamap long ol tempereja long tempereja. bilong daunim ol hevi insait .
