Txoj Kev Taws Teeb Ua Tau Tus Kheej

Ningbo Qianhao Hlau Khoom Co., Ltd | Updated: Jul 03, 2017

Valve casting forming performance: casting temperature using 1540 ~ 1570 ℃, casting forming performance zoo dua, casting shrinkage feem ntau 2% rau 2.5% ntawm phab ntsa thickness. Yuav tsum xav txog qhov kev tsim ntawm qhov siab, qhov chaw nce thiab xaiv cov qauv khoom. Thaum lub plhaub zis loj, yuav kho tau tom qab kho cua sov, tom qab kho qhov chaw los ntawm kev kho cua sov uas yuav tsum tau kho kom sov dua.

Piv nrog rau lwm cov hlau casting txheej txheem, lub valve casting manufacturing txheej txheem muaj cov yam ntxwv nram qab no:

① valve casting raug txoj kev thiab cov txheej txheem soj ntsuam ntau dua.

Txoj hlua khoob vov plawg yog ib txoj haujlwm hu ua nyias plab nyias lub cev. Lub castings yuav tsum tau ib tus ntse, pov ib lo lus meej, tshwj xeeb tshaj yog kom muaj qhov ntom ntom. Yuav ua kom tau raws li cov cai saum toj no, casting yuav tsum siv cov kev ntsuas, xws li kev siv cov khoom ua kom tsis muaj zog thiab kev tswj cov dej hauv cov xuab zeb, kev ua qauv yuav tsum tau muab pov tseg kom paub tseeb tias cov xuab zeb hardness, siv lub hau tsim nyog thiab tswj nruj Pouring ceev thiab kub. Vim muaj kev kawm siab, cov txheej txheem casting ntawm lub valve casting yog teeb meem ntau tshaj qhov kev pov thawj.

Tsis tas li ntawd, lub valve casting ntxiv mus xyuas qhov loj me, qhov tseeb qhov tseeb thiab qhov zoo li, thiab qee cov muaj rau lub microstructure, mechanical zog, corrosion tsis ua hauj lwm thiab tsis kuaj thiab lwm yam kev xeem, yog li cov valve casting tshuaj txheej txheem ntau dua.

② valve casting ntawm lub tshuab los nruab ntau nyuaj

Valve casting qauv, qhov zoo tshaj qhov nyuaj, qee qhov chaw muaj nyias, daim ntawv me, tsis rigidity. Thaum uas ua haujlwm ntawm lub tshuab, qhov teebmeem thiab clamping yog qhov nyuaj, feem ntau yog li xav tau kev kho tshwjxeeb.

Qee qhov chaw ntawm qhov chaw, qhov chaw ntawm lub hauv paus ntom ntom ntawm qhov qis dua, qhov chaw siab plawg, thiab qee zaus txawm tias siv cov khoom tsis ua haujlwm. Thiab cov zauv ntawm qhov ntom ntom thiab lwm qhov chaw ntawm qhov tseeb thiab qhov yuav tsum ua kom siab dhau heev lawm, nws yog qhov nyuaj ua kom muaj kev ua tiav. Yog li, yuav kom tau raws li qhov xav tau ntawm tus txheej txheem, feem ntau yuav tsum txhim kho qhov tseeb ntawm qhov chaw ntawm qhov chaw thiab txo qhov kev npau taws, los yog hauv cov zauv uas tsis ua haujlwm ntawm qhov chaw ntawm qhov chaw, uas ua rau kom tsis muaj teeb meem ntawm qhov kev lag luam .

③ nyuaj rau tshuab ua

Vim ntau ntau cov ntaub ntawv pov thawj castings, ntxiv rau ntau hom hlau, steel hlau, feem ntau ntawm nws lub zog, corrosion kuj thiab siab tawv ntaub ntawv txiav kev txom nyem, nws yog qhov nyuaj ua kom tiav cov feem yuav tsum tau ua qhov tseeb thiab qhov chaw ntawm lub plhaub zais Qhov Valve casting ntom ntom geometric puab raug thiab qhov yuav tsum ua kom siab dhau qhov siab, yog li ua qhov teeb meem ntawm qhov kev siv casting machining. Nyob rau tib lub sij hawm, cov ntaub ntawv siv cov khoom siv txiav nyiaj pluag tsis zoo, tab sis kuj yog rau cov khoom siv kev siv tshuab, cov cuab yeej cuab tam, txiav cov khoom siv tshuab thiab khoom siv, thiab coj cov teeb meem tshiab.
