Vim stainlesshlau forgingsfeem ntau siv nyob rau hauv txoj hauj lwm tseem ceeb ntawm lub tshuab, yog li qhov zoo ntawm stainlesshlau forgingstseem ceeb heev. Vim lub sab hauv zoo ntawm stainlesshlau forgingstsis tuaj yeem kuaj los ntawm txoj kev nkag siab, yog li kev tshuaj xyuas lub cev tshwj xeeb thiab tshuaj lom neeg siv los ntsuas.

Ua ntej, txhua yam khoom ntawm forgings
Mechanical Properties ntawmforgingsraug txiav txim raws li cov khoom xav tau. Cov txheej txheem xeem tau muab faib ua hardness test, tensile test, impact test and fatigue test.
1. Kev kuaj Hardness
Hardness yog qhov deformation tsis kam ntawm cov khoom nto, nws yog ib qho kev ntsuas uas ntsuas cov khoom siv hlau mos. Hardness thiab lwm yam khoom siv kho tshuab muaj qee yam kev sib raug zoo, yog li lwm yam khoom siv hluav taws xob tuaj yeem kwv yees los ntawm tus nqi hardness. Kev kuaj Hardness tsis tas yuav npaj cov qauv tshwj xeeb, thiab nws yuav tsis ua kom puas cov qauv, yog li kev sim hardness yog feem ntau siv los tsim cov cuab yeej cuab yeej xeem txoj kev.
Feem ntau siv cov kev sim hardness thiab qhov sib txawv yog: Brinell hardness (HB), Rockwell hardness (HRC), Vickers hardness (HV), Shore hardness (HS), thiab cov hardness tester.
2. Tensile xeem
Los ntawm kev siv lub tensile load rau cov qauv ntawm ib tug tej yam duab los ntawm lub tensile tshuab, proportional elongation stress, yield point, tensile zog, elongation thiab txo ntawm seem ntawm cov khoom hlau yog ntsuas.
3. Kev sim cuam tshuam
Qhov cuam tshuam toughness ntawm cov hlau tau txais los ntawm kev siv lub pendulum high-speed pendulum los cuam tshuam cov qauv nrog notch.
4. Kev sim qaug zog
Cov kev txwv qaug zog thiab qaug zog ntawm cov hlau tuaj yeem ntsuas tau tom qab rov ua dua lossis hloov kev ntxhov siab.
Ob, tsis muaj kev puas tsuaj tshuaj xyuas ntawm forging
Kev kuaj tsis muaj kev puas tsuaj tuaj yeem muab faib ua kev kuaj hluav taws xob, kuaj ultrasonic, kuaj cov khoom sib nqus, kuaj pom thiab kuaj tam sim no. Forgings feem ntau yog siv rau hauv kev kuaj ultrasonic thiab sib nqus particle kuaj.
1. Ultrasonic tshuaj xyuas
Ultrasonic yoj (feem ntau yog ntau dua 20000Hz) yuav muaj kev cuam tshuam thiab thim rov qab ntawm cov khoom sib txawv. Yog li ntawd, yog tias muaj qhov tsis xws ntawm cov khoom sib txawv hauv cov khoom siv, yoj kev xav thiab attenuation yuav raug tsim. Lub hav zoov ntawm qhov tsis xws luag tuaj yeem txiav txim tau los ntawm waveform signals.
Rau loj thiab nruab nrabforgings, kev kuaj ultrasonic yog ib qho tseem ceeb ntawm kev kuaj tsis muaj kev puas tsuaj.
2. Magnetic particle soj ntsuam
Qhov tsis xws luag xws li tawg, qhov pores thiab nonmetallic inclusions nyob rau thiab ze ntawm qhov chaw forging tuaj yeem kuaj xyuas los ntawm kev tshuaj xyuas cov khoom sib nqus. Vim nws cov cuab yeej siv yooj yim, kev ua haujlwm yooj yim thiab muaj kev nkag siab zoo, txoj kev no feem ntau siv los kuaj me me thiab nruab nrab-qhov loj me tuag forgings uas ua rau ntau qhov ntau.
Peb, lub zog qis thiab kev kuaj pob txha
Kev tshuaj xyuas lub zog qis yog cov qauv tom qab qee qhov kev ua tiav, thiab tom qab ntawd nrog lub qhov muag liab qab hauv 10 ~ 30 npaug ntawm lub iav tsom iav los xyuas cov qauv, txhawm rau nrhiav qhov tsis xws ntawm stainless hlau forgings. Streamline, dendrite, xoob, naphthalene, pob zeb tawg thiab lwm yam tsis xws luag tuaj yeem kuaj xyuas los ntawm kev txiav cov qauv wafer thiab acid etching. Txhawm rau txhawm rau txheeb xyuas kev sib cais, tshwj xeeb tshaj yog qhov tsis sib xws ntawm sulfide, sulfur luam ntawv txoj kev siv.
Plaub, kev tshuaj xyuas lub zog siab
Stainless hlau forgings yuav ua rau hauv ib qho piv txwv nyob rau hauv lub tshuab kuaj kab mob los xyuas cov forgings sab hauv (los yog tawg) ntawm lub xeev ntawm lub koom haum lossis microscopic defects. Cov qauv sab hauv thiab kev faib tawm ntawm cov forging tuaj yeem kuaj xyuas los ntawm kev txiav cov qauv longitudinal. Deg tsis xws luag xws li decarburization, coarse-grained, carburized thiab hardened txheej tuaj yeem kuaj xyuas los ntawm kev txiav cov qauv transverse.
