What kind of heat treatment can the induction hardening na’ura mai girma-mita yi a kan nada spring?

Diamita na kayan sashe zagaye ya fi 12mm, gefen tsawon kayan sashin rectangular ya fi 10mm, kuma ruwan kwal tare da kauri mai kauri fiye da 8mm ana kera shi gabaɗaya ta hanyar samar da zafi. A takamaiman tsari ne karfe dubawa-yanke abu-dumama karfe sanda zafi nada spring-siffar-zafi siffata -Tempering-karshen surface nika-harbi peening-zafi matsa lamba jiyya-aibi gano-zane-zane ko phosphating fesa-bincike-marufi. A yau, zan gaya muku menene hanyoyin da na’urar tauraruwar induction ke iya aiwatarwa.

1. Bar dumama ana kullum da za’ayi ta high-mita quenching inji tare da atomatik ciyar da fitarwa. Diamita na kayan zai iya kaiwa 60mm, kuma tsawon kada ya wuce 8m. The dumama zafin jiki na karfe mashaya ne kullum 880-950 ℃.

2. Coiling, ta yin amfani da na’ura mai sarrafa kwamfuta ko na’ura mai zafi mai zafi, tare da diamita na aiki na 20-60mm, da zafi-nadi da zafi da kayan mashaya a cikin maɓuɓɓugar ruwa na matsawa na ƙayyadaddun da ake bukata. Zazzabi na bazara bayan zafin nada mai zafi ya kamata ya kasance sama da 840 ℃, wanda ya dace da kashe kai tsaye. Wato ana kashe shi a cikin mai a 50-80 ° C. Za a iya sarrafa zafin jiki na tankin mai na bazara a cikin kewayon 120-180 ℃ don hana nakasawa da rage damuwa. Bayan babban na’ura mai taurin shigar da induction ta kashe shi, taurin bazara ya fi 54HRC.

3. Tempering, da bazara bayan quenching dole ne a tempered a cikin 2h don hana quenching fasa. The tempering tanderun rungumi dabi’ar PLD iko, sabõda haka, da tempering zafin jiki ne sarrafawa a cikin ± 3 ℃, da kuma tempering zafin jiki ne 400-450 ℃. Bayan tempering, taurin bazara na iya isa 45-50HRC. Za a bi da maɓuɓɓugan ruwa waɗanda ke da saurin nakasu a lokacin aikin jiyya na zafi daban, kuma tsarin siffa ya kamata a ƙara gabaɗaya.
