zofunika

Chida Chida cha H13 ndichitsulo chantchito yotentha ya chromium-molybdenum yomwe imagwiritsidwa ntchito kwambiri pantchito yotentha komanso ntchito yozizira. 

Kuuma kotentha (mphamvu yotentha) ya H13 kumatsutsana ndikutentha kwa kutopa komwe kumachitika chifukwa cha kutentha kozungulira ndi kuzirala kozungulira mu 

ntchito yotentha tooling. Chifukwa cha kuphatikiza kwake kolimba kwambiri komanso kulimbana ndi kutopa kotentha 

(Amadziwikanso kuti kutentha) H13 imagwiritsidwa ntchito popangira zida zotentha kuposa chida chilichonse chachitsulo.

Zomwe zimapezekanso ngati Electro-Slag-Remelted (ESR) ndi Vacuum-Arc-Remelted (VAR). 

Njira zotsitsimutsazi zimapangitsa kuti mankhwala azikhala ofanana kwambiri, kukonza kwa carbide size, komanso kusintha komwe kumalumikizidwa mu 

katundu wa makina ndi kutopa.


Mapulogalamu:

Kuyika, zokutira, ndi zotsekemera zimafera kufa, kufa kumanja kuponyera mfuti, kufa kumoto kotentha, kufa kwa extrusion, ndi zotsekemera za pulasitiki ndi zinthu zina zomwe zimafuna kulimba kwambiri komanso kupindika kwambiri.

zofunika:Kutentha:Mtima mwamsanga pambuyo pa kuzimitsa. Mtundu woyatsa kwambiri ndi 1000-1150 ° F (538-621 ° C). Gwiritsani kutentha kwa ola limodzi pa inchi (1mm) makulidwe, koma kwa maola awiri osachepera, kenako mpweya wabwino kuzizira kozungulira. Kutentha kawiri kumafunika. Kuti tiwonjezere kulimba ndi magwiridwe antchito, kupsa mtima kwachitatu kumagwiritsidwa ntchito ngati kupumula kwa nkhawa mukamaliza kumaliza kukonza, kupera, ndi ntchito ya EDM kumalizika pachidacho.

Annealing iyenera kuchitidwa mutatha kugwira ntchito yotentha komanso musanalimbikitsenso.

Kutentha pamlingo wosapitirira 400 ° F pa ola limodzi (222 ° C pa ola limodzi) mpaka 1575-1625 ° F (857-885 ° C), ndikugwiritsanso kutentha kwa ola limodzi pa inchi yakulimba kwambiri; Maola awiri osachepera. Kenako muzizizira pang'onopang'ono ndi ng'anjo pamlingo wosapitirira 1 ° F pa ola limodzi (2 ° C pa ola limodzi) mpaka 50 ° F (28 ° C). Pitirizani kuzizira kutentha kozungulira m'ng'anjo kapena mumlengalenga. Chowuma chotsatira chimayenera kukhala chambiri cha 1000 HBS.
