Momwe Mungagwiritsire Ntchito Ndodo ya Tungsten Carbide Composite

1. Sungani pamwamba paukhondo

Zomwe zimapangidwira ndodo ya carbide ziyenera kutsukidwa bwino komanso zopanda dzimbiri ndi zinthu zina zakunja. Kuwombera mchenga ndi njira yokondedwa; kugaya, kutsuka mawaya, kapena kusenda mchenga nazonso n’zokhutiritsa. Kuphulika kwa mchenga pamwamba kumapangitsa kuti pakhale zovuta mu tinning matrix.

2. Kutentha kwa kuwotcherera

Onetsetsani kuti chidacho chayikidwa kuti chiwongolere pansi. Ngati n'kotheka, tetezani chidacho pamalo abwino a jig.

Yesetsani kusunga nsonga ya nyali yanu mainchesi awiri kapena atatu kuchoka pamtunda womwe mukuvala. Pang'onopang'ono yambani kutentha mpaka pafupifupi 600 ° F (315 ° C) mpaka 800 ° F (427 ° C), kusunga kutentha kochepa kwa 600 ° F (315 ° C).

3. Njira zisanu za kuwotcherera

(1)Kutentha koyenera kukafika, perekani pamwamba kuti muveke ndi brazing flux powder. Mudzawona kuwira kwa flux ndikuwira ngati pamwamba pa workpiece yanu ndi kutentha mokwanira. Flux iyi imathandizira kupewa mapangidwe a oxides mu matrix osungunuka panthawi yovala. Gwiritsani ntchito tochi ya oxy-acetylene. Kusankha malangizo kumatengera momwe zinthu ziliri- #8 kapena #9 pakuvala madera akulu, #5, #6 kapena #7 kumadera ang'onoang'ono kapena ngodya zothina. Sinthani ku moto wocheperako wosalowerera ndale ndi zoyezera zanu zoyikidwa pa 15 pa acetylene ndi 30 pa oxygen.

(2)Pitirizani kutenthetsa pamwamba kuti muveke mpaka nsonga zamagulu a carbide zikhale zofiira ndipo nsonga yanu yotentha imakhala yamadzimadzi komanso yoyera.

(3)Pokhala 50 mm mpaka 75 mm kuchoka pamwamba, sungani kutentha kumalo amodzi mpaka kufiira kofiira, 1600 ° F (871 ° C). Tengani ndodo yanu yowotchera ndikuyamba kuwotcha pamwamba ndi chivundikiro chakuda cha 1/32 "mpaka 1/16". Ngati pamwamba patenthedwa bwino, ndodo yodzaza madzi idzayenda ndikufalikira kutsatira kutentha. Kutentha kosayenera kumapangitsa kuti chitsulo chosungunula chizime. Pitirizani kutentha ndi malata pamwamba kuti muveke mofulumira monga momwe matrix osungunula amamangira.

(4) Tengani ndodo yanu ya tungsten carbide ndikuyamba kusungunula gawo la 1/2 "mpaka 1". Izi zitha kukhala zosavuta poviika kumapeto mu chitini chotseguka.

(5)Deralo litaphimbidwa ndi ndodo yophatikizika, gwiritsani ntchito tinning kuti mukonzekere ma carbide okhala ndi m'mphepete mwawo. Gwiritsani ntchito mayendedwe ozungulira ndi nsonga ya nyali kuti musatenthedwe pamalo ovala. Sungani kuchuluka kwa carbide muzovala kukhala wandiweyani momwe mungathere.

4. Kusamala kwa wowotcherera

Onetsetsani kuti malo ogwirira ntchito ali ndi mpweya wabwino. Gasi ndi utsi wopangidwa ndi flux kapena matrix ndizowopsa ndipo zimatha kuyambitsa nseru kapena matenda ena. Wowotchera ayenera kuvala #5 kapena #7 lens yakuda, zobvala m'maso, zotsekera m'makutu, manja aatali, ndi magolovesi nthawi zonse pakugwiritsa ntchito.

5. Chenjezo

Osagwiritsa ntchito ndodo yochulukira ya matrix - idzachepetsa kuchuluka kwa carbide matrix.

Osawotcha ma carbides. Kuwala kobiriwira kumawonetsa kutentha kwambiri pama carbides anu.

Nthawi iliyonse zidutswa zanu za carbide zikana kukhala malata, ziyenera kuchotsedwa pamadzi kapena kuchotsedwa ndi ndodo yowotcha.

A. Pamene ntchito yanu ikufuna kuti mumange mapepala kupitirira 1/2 ", izi zingafunike chitsulo chochepa cha 1020-1045 chopangidwa ndi chitsulo chowotcherera ku chida chanu mu malo ovala.

B. Mutatha kuvala dera lanu, muziziziritsa chidacho pang'onopang'ono. Osazizira ndi madzi. Osatenthetsanso malo ovalawo powotchera pafupi ndi malowo.

6. Momwe mungachotsere ndodo ya carbide composite

Kuti muchotse malo anu ophatikizika atazimitsidwa, tenthetsani malo a carbide kuti akhale ofiira osawoneka bwino ndipo gwiritsani ntchito burashi yachitsulo kuti muchotse grits ndi matrix pamwamba. Osayesa kuchoka ku ma carbide grits ndi matrix ndi tochi yanu yokha.
