Yuav Ua Li Cas Txiav Txim Siab Ntawm H13 Khoom

Cov txheej txheem tseem ceeb rau kev ntsuas qhov ruaj khov ntawm cov khoom siv H13 yog txhawm rau ntsuas nws cov metallographic sib xws, kev kho cua sov txheej txheem traceability, thiab hardness uniformity. Thaum ua ke, peb lub ntsiab lus tsim lub voj kaw uas txiav txim siab cov khoom siv ruaj khov.

1. Ceev ntawm -Qhov Kev Ntsuam Xyuas Qhov Kev Ntsuas Hardness Uniformity

Kev Ntsuas Cov Txheej Txheem: Ntsuas peb mus rau tsib lub ntsiab lus tseem ceeb (xws li qhov chaw, ntug, thiab thaj tsam tuab) ntawm txhua qhov chaw ua haujlwm uas siv lub ntsuas qhov tawv tawv.

Kev lees txais: batch nruab nrab hardness zoo ib yam ntawm 48 thiab 52 HRC; ib zaug -piece hardness range Tsawg dua los yog sib npaug rau 2 HRC.

Kev Ceeb Toom Tsis Zoo: Cov yam ntxwv ntawm cov khoom tsis ruaj khov tuaj yeem tshwm sim los ntawm qhov tsis sib xws los yog tsis txaus tempering yog tias qhov ntau tshaj 3 HRC.

Tswv yim tswv yim: 100% kev ntsuam xyuas ntawm cov khoom tseem ceeb; sampling tus nqi tsawg kawg yog 10% ib batch.

2. Metallographic Analysis (Basis for Authoritative Judgement)

Kev ua haujlwm ruaj khov ntawm Microstructure nta Kev ua haujlwm tsis txaus ntseeg

Matrix Structure: Dispersed carbides ntxiv rau cov khoom siv tempered martensite Network carbides, coarse martensite, lossis ferrite seem

Tsis muaj oxidation, tsis muaj microcracks, thiab ib tug ntshiab grain ciam xeev Microcracks (overheating), remelting spheres, thiab oxidation ntawm lub grain interface

Network dispersion, homogenous nag lossis daus aggregation, nplua carbide tis, thiab txo toughness

Kev Ntsuas Kev Ntsuas: Siv lub tshuab ntsuas metallographic nrog qhov loj ntawm 400 × lossis ntau dua tom qab kuaj thiab ua tiav. Kev ntsuas tsawg kawg yog tsib feem pua ​​​​ntawm txhua pawg tau qhia.

3. Kaw -Loop Quality Assurance (Txheej txheem Traceability)

Rauv Qhov Kub Kub Profile: Txheeb xyuas qhov ntsuas kub thaum lub sij hawm tempering nyob ruaj khov ntawm 550-600 degree, nrog rau cov cua sov thiab cua txias kom tsim nyog, thiab tsis muaj kev cuam tshuam lossis kev hloov pauv;

Batch Report: Muab cov ntaub ntawv ua haujlwm, kuaj cov neeg ua haujlwm cov ntsiab lus, thiab cov ntaub ntawv ntsuas qhov nyuaj;

Kev Pabcuam Kev Tsim Nyog: Muab qhov kev nyiam rau cov chaw kho cua sov nrog CQI-9 daim ntawv pov thawj, uas nws cov txheej txheem tsis sib xws thiab lawv cov ntaub ntawv muaj meej.

"Data traceability, organisation credibility, and process controllability" yog cov ntsiab cai tseem ceeb ntawm kev nyab xeeb.
