Vim li cas peb lub phaj hnav muaj kev tiv thaiv zoo li no?

1. Cov tshuaj sib xyaw ua ke yog qhov tseem ceeb.

Cov khoom xyaw tseem ceeb ntawm Wodon phaj yog C (%): 3.0-5.0 thiab Cr (%): 25-40.

Qhov sib piv tshuaj lom neeg no ua rau muaj ntau cov khoom tawv Cr7C3 chrome carbide. Qhov micro-hardness (txog HV1800)ntawm cov nocov khoom me me thoob plaws hauv txheej yuav lav qhov chaw hnav tsis kam zoo.

 

 

 

 

 

 

 

 

 

 

Kev Ntsuas Kev Ua Tau Zoo:

Cov khoom siv sim: Lub log roj hmab quartz xuab zebtshuab kuaj kev puas tsuaj.

Cov xwm txheej: 1. Xaiv cov qauv loj tib yam rau cov ntaub ntawv sib txawv thiab cov neeg tsim cov phaj hnav, thiab muab tso rau hauvnyob rau hauv tib lub sijhawm hnav ua haujlwm hauv peb cov khoom siv kuaj.

2. Chromium carbide microstructure

Qhov kev tiv thaiv kev hnav ntawm cov phaj hnav feem ntau nyob ntawm qhov nyuaj, cov duab, qhov loj me, qhov ntau thiab kev faib tawm ntawm cov chromium.cov khoom tawv carbide.

 

Raws li koj tuaj yeem tshawb xyuas ntawm daim duab, qhov ntim ntawm carbide (Cr7C3) ntawm cov qauv me me yog siab dua 50%.

 

3. Lub zog sib txuas ntawm cov txheej txheej thiab lub phaj hauv paus.

Cov txheej sab saud thiab lub phaj hauv paus sib txuas zoo heev. Cov txheej sab saud yuav nkag mus rau hauv lub phaj hauv paus li ntawm 0.8mm-1.8mm, ncav cuagtxog li 350Mpa hauv peb qhov kev sim.
