Me yasa zabar mitar da ta dace don tanderun narkewa

Zabar wani injin wutar lantarki tare da mitar da ba ta dace ba zai shafi ingancin dumama kayan aikin: girman ikon; matsalar ƙayyadadden saurin dumama da ingantaccen aiki na kayan aikin; lokacin dumama yana jinkirin, ingantaccen aikin aikin yana da ƙasa, dumama ba daidai ba ne, kuma zafin jiki ba zai iya biyan buƙatun ba. Zai haifar da lalacewa ga aikin aikin kuma ya haifar da kishiyar sakamako.

Yadda za a zabi mitar daidai daidai? Da fatan za a tuna da waɗannan kalmomi:

(1) Mafi girma diamita na workpiece, ƙananan mita ya kamata;

(2) Matsakaicin madaidaicin Layer quenching, mafi girman mitar;

(3) Mafi girman girman walda, ƙananan mitar ya kamata ya kasance.

Fa’idodin quenching na saman a cikin tanderun narkar da matsakaicin mitar idan aka kwatanta da quenching na kayan aikin dumama na yau da kullun:

1. saurin dumama yana da sauri sosai, wanda zai iya faɗaɗa yanayin canjin zafin jiki na A kuma ya rage lokacin canji.

2. Bayan quenching, musamman lafiya cryptocrystalline martensite za a iya samu a saman da workpiece, tare da dan kadan mafi girma taurin (2～3HRC). Low brittleness da babban gajiya ƙarfi.

3. The workpiece sarrafa ta wannan tsari ne ba sauki da za a oxidized da decarburized, kuma ko da wasu workpieces za a iya kai tsaye harhada da kuma amfani da bayan aiki.

4. Zurfafa Layer Layer, mai sauƙin sarrafawa da aiki
