Khoom Taw Qhia

Cov khoom siv hauv tsev yog cov khoom siv uas tsis yog cov khoom siv hauv tsev uas pab tsim lub tsev thiab kev tsim kho, xws li scaffolding, yeeb nkab xov regulators rau kev tsim kho, lub tsev khi rods, daim duab peb sab lub tsev brackets, steel bar pob qij txha, thiab lwm yam.

Cov khoom siv hauv tsev yog cov khoom tseem ceeb ntawm lub tsev, nrog rau cov kab: kab ke, cov kab ywj pheej, cov kab ke, cov pob zeb luv luv, kab, kab L-shaped; cib kem, pob zeb kem, thiab ntoo kem.

Beams: ncej beams, txuas kab teeb, lintels, nplhaib beams, cantilever beams, arc beams; steel beams, ntoo beams, qhob beams.

Board: cam khwb cia-hauv-qhov chaw board, prefabricated slab, prefabricated hollow board; reinforced pob zeb board, ntoo board.

Phab ntsa: cib ntsa, pob zeb phab ntsa, ru tsev parapet, sib faib phab ntsa.

Qhov rooj: qhov rooj ntoo, qhov rooj plywood, steel qhov rooj.

Qhov rai: steel qhov rais, ntoo qhov rais, aluminium alloy qhov rais, yas steel qhov rais.

Kev tsim kho cov khoom siv suav nrog kwv yees li 3 feem pua ​​-5 feem pua ​​ntawm cov nqi kho tsev. Qhov kev faib ua feem me me, tab sis nws tsis tuaj yeem tsis quav ntsej. Nws siv cov haujlwm muab faib ua pawg dav dav. Cov khoom siv kho vaj tse feem ntau muaj xws li cov xauv, pob khawm, cov hlua khi, cov tes tuav, cov hlua khi, cov ntsia hlau, cov hlua khi, lub qhov rooj kaw, cov khaub ncaws hooks, cov hlaws dai, cov ntawv khij nyiab, cov board pins, thiab lwm yam. Cov khoom siv chav dej kho vajtse muab faib ua pawg thiab cov khoom siv hauv chav ua noj. Kuv tsuas yog qhia txog cov khoom siv uas nquag siv, pawg.

Feem ntau, qhov tseeb ntawm cov hlau castings raug cuam tshuam los ntawm ntau yam xws li cov qauv casting, cov khoom siv casting, pwm ua, plhaub ua, roasting, pouring, thiab lwm yam. Txhua qhov txuas thiab kev ua haujlwm tsis tsim nyog yuav hloov qhov shrinkage tus nqi ntawm castings. Yog li ntawd, qhov tseeb qhov tseeb ntawm qhov casting deviates los ntawm qhov yuav tsum tau ua.

Cov hauv qab no yog cov yam ntxwv uas tuaj yeem ua rau muaj qhov tsis xws luag hauv qhov tseeb ntawm cov khoom cam khwb cia

(1) Kev cuam tshuam ntawm cov qauv casting ntawm lub tsev accessories:

a. Lub phab ntsa ntawm casting yog tuab thiab shrinkage yog loj, thiab phab ntsa ntawm casting yog nyias thiab shrinkage yog me me.

b. Tus nqi shrinkage dawb yog loj, thiab tus nqi hindered shrinkage yog me me.

(2) Kev cuam tshuam ntawm cov khoom siv casting ntawm lub tsev accessories:

a. Qhov siab dua cov ntsiab lus carbon nyob rau hauv cov khoom, qhov me me ntawm linear shrinkage, thiab qis cov ntsiab lus carbon, qhov loj ntawm linear shrinkage.

b. Lub casting shrinkage tus nqi ntawm cov khoom siv Architectural Poob Wax Castings yog raws li nram no: casting shrinkage tus nqi K=(LM-LJ)/LJ × 100 feem pua, LM yog cov kab noj hniav loj, thiab LJ yog qhov loj casting. K yog cuam tshuam los ntawm cov hauv qab no: ciab qauv K1, casting qauv K2, alloy hom K3, thiab pouring kub K4.

(3) Cov nyhuv ntawm pwm ua rau ntawm cov kab shrinkage ntawm castings:

a. Qhov cuam tshuam ntawm kev txhaj tshuaj wax kub, wax txhaj tshuaj siab, thiab lub sijhawm tuav lub sijhawm ntawm qhov loj ntawm cov pwm peev yog pom tseeb nrog rau qhov kub thiab txias, ua raws li kev txhaj tshuaj wax. Lub sij hawm tuav lub sij hawm muaj kev cuam tshuam me ntsis ntawm qhov kawg loj ntawm cov peev pwm tom qab lub peev pwm tsim.

b. Cov linear shrinkage ntawm cov khoom siv quav ciab (pwm) yog hais txog 0.9-1.1 feem pua ​​.

c. Thaum lub peev pwm khaws cia, nws yuav qis dua, thiab nws cov nqi shrinkage yog kwv yees li 10 feem pua ​​​​ntawm tag nrho cov shrinkage. Txawm li cas los xij, tom qab 12 teev ntawm kev cia, qhov loj ntawm cov pwm peev txheej yog qhov ruaj khov.

d. Lub radial shrinkage tus nqi ntawm cov quav ciab pwm tsuas yog 30-40 feem pua ​​ntawm cov shrinkage tus nqi nyob rau hauv lub longitudinal kev taw qhia, thiab lub zog ntawm cov wax txhaj tshuaj kub nyob rau hauv lub free shrinkage tus nqi yog deb tshaj qhov cuam tshuam rau lub hindered shrinkage tus nqi ( qhov zoo tshaj plaws wax txhaj tshuaj kub yog 57-59 degree C, qhov kub thiab txias Qhov siab dua qhov contraction, ntau dua qhov contraction).

(4) Kev cuam tshuam ntawm cov khoom siv plhaub:

Zircon xuab zeb, zircon hmoov, Shangdian xuab zeb, thiab Shangdian hmoov yog siv, vim hais tias ntawm lawv me me expansion coefficient, tsuas yog 4.6 × 10-6 / degree, yog li lawv yuav tsis quav ntsej.

(5) Kev cuam tshuam ntawm plhaub roasting:

Vim qhov me me expansion coefficient ntawm lub plhaub, thaum lub plhaub kub yog 1150 degree, nws tsuas yog 0.053 feem pua, yog li nws tuaj yeem tsis quav ntsej.

(6) Kev cuam tshuam ntawm qhov kub thiab txias:

Qhov siab dua qhov kub thiab txias, qhov ntau dua qhov shrinkage, thiab qhov kub ntawm qhov pouring qis dua, qhov me me qhov shrinkage, yog li qhov kub ntawm pouring yuav tsum tsim nyog.
