Na’urar kashe wuta da yawa hanyar fushi

Kayan aiki masu saurin kashewa suna amfani da tasirin fata, wato, fasahar dumama shigar da kayan aiki, don haɓaka yanayin zafin aikin da sauri, kuma zafin saman aikin na iya tashi zuwa 800-1000 ° C a cikin ƴan daƙiƙa kaɗan. Tare da haɓaka masana’antu, fasahar dumama shigar da kayan aikin kashe mitoci da yawa an ci gaba da inganta, kuma ana ci gaba da faɗaɗa aikace-aikacen. Bayan da workpiece ne quenched da high-mita quenching kayan aiki, shi yana bukatar da za a tempered a lokaci don rage brittleness na quenching mika mulki yankin, kawar da ciki danniya bayan quenching, inganta plasticity da taurin, da kuma cimma da ake bukata inji Properties. A taurin workpiece bayan high-mita quenching ne mafi girma fiye da na talakawa quenching, da kuma taurin ne sauki rage bayan tempering. Editan mai zuwa yana gabatar da hanyoyin zafi guda uku da aka saba amfani da su anan:

1. Yin zafi a cikin tanderu:

Furnace tempering ne ya fi na kowa Hanyar tempering, kuma shi ne dace da daban-daban masu girma dabam na workpieces. Gabaɗaya ana yin zafi a cikin tanderun rami tare da fan. Ya kamata a ƙayyade zafin jiki na zafin jiki bisa ga kayan aiki na kayan aiki, taurin bayan quenching da taurin da ake bukata. Gabaɗaya, zafin zafin jiki na gami karfe ya fi na carbon karfe; da taurin bayan quenching ne m, kuma tempering zafin jiki ya kamata a saukar da yadda ya kamata.

2. Haushin kai:

Abin da ake kira zafin kai shine sarrafa lokacin sanyaya na induction quenching na babban mitar quenching kayan aiki, ta yadda saman workpiece ke kashe amma ba sanyi ta. Zafin da ya rage a cikin yankin quenching yana da sauri canjawa wuri zuwa ga quenched saman na workpiece da kuma kai wani zazzabi don sa saman quenched Layer zafi. Canjin yanayin zafin jiki na shigar da taurare kayan aiki yayin zafin kai. Haushin kai ya dace da dumama lokaci guda da kashe kayan aiki tare da siffofi masu sauƙi.

3. Induction zafin jiki:

Ƙarar zafin jiki Bayan shigar da tauraruwar dogayen igiyoyi da hannayen riga, ana amfani da zafin ƙara wani lokaci. Yawan zafin jiki na induction yawanci yana daidaitawa tare da taurin shigar don samar da bututun maganin dumama zafi. Bayan workpiece ne mai tsanani da quenching inductor kuma sanyaya da ruwa fesa zobe, shi ne ci gaba mai tsanani da tempering inductor ga tempering.

Idan aka kwatanta da zafin wuta a cikin tanderun, ƙaddamar da zafin jiki yana da ɗan gajeren lokacin dumama da saurin dumama. Sakamakon shine microstructure tare da babban bambanci. Juriya na lalacewa da tasirin tasiri bayan zafin jiki sun fi na masu zafi a cikin tanderun wuta. Wutar tana da yawa.
