Peb feem ntau hais tias cov yeeb nkab kub uas yog hais txog cov yeeb nkab steel uas tau nthuav dav thiab muaj cov qauv hluav taws xob tsis sib xws Cov kav dej tuaj yeem tsim cov kav dej txheem, thiab tus nqi qis thiab kev ua haujlwm tsawg yog siab. Nws yog ib txoj kev ua ib qho rau cov kav dej seamless. Vim yog cov khoom siv hluav taws xob siab ntawm cov ntoo hluav taws xob uas muaj ntau dua 508 hli tsim los yog nws.

 

Qhov ob-kauj ruam tawm cov yeeb nkab expander siv rau kub-expanded steel kav hlau ua ke thev naus laus zis induction cua sov thev naus laus zis, thiab hydraulic tshuab hauv ib lub tshuab. Nrog nws cov txheej txheem tsim nyog, kev siv peev qis, thiab cov khoom lag luam zoo dua qub tau hloov cov txheej txheem rub tawm-hom uas tuaj yeem siv tus txheej txheem ntawm cov yeeb nkab kev lag luam.

 

Nws yuav tsum raug sau tseg tias cov kws kho tshuab ntawm kub-nthuav steel kav yog feem ntau tsis zoo dua li kub-polled steel kav.

 

Cov txheej txheem dav dav ntawm cov yeeb nkab ntawm cov yeeb nkab yog txhawm rau txhim kho cov yeeb nkab ntawm cov yeeb nkab ntawm cov yeeb nkab, thiab kev sib txuas thiab kho qhov hlau hauv cov yeeb nkab. Kev sib txuas ntawm cov yeeb nkab thiab cov pob zeb saum toj kawg nkaus nyob hauv qab no, koj yuav tsum tau tawm ntawm lub raj ua ntej, kom lub raj xa mus rau sab saum toj anvil thiab txuas ntxiv. Sab saum toj Anvil dier Cov yeeb nkab lub taub. Tom qab tag nrho cov yeeb nkab hla, cov yeeb nkab yuav tsis ncaj vim yog cov txheej txheem cua sov, yog li nws xav tau ncaj nws.

Qhov saum toj no yog cov ntsiab lus yooj yim ntawm thermal expansion thev naus laus zis.

 Cov hauv qab no yog cov mis uas cuam tshuam ntawm thermal exetanded yeeb nkab

 

Nthuav hnyav:

Carbon Hlau: (txoj kab uas hla-tuab)× qhov tuab× 0.02466 = hnyavt ntawm ib meter (kg)

Alloy: (txoj kab uas hla-tuab)× qhov tuab× 0.02483 = nyhavntawm ib meter (kg)

Tus naj npawb ntawm metres tom qab kub nthuav dav:

Thawj Tube Diam÷ Kub nthuav dav txoj kab uas hla× 1.04× ntev *

 

Thawj Tube Meters:

nthuav ntev× (taub÷ Thawj Tube Diam÷ 1.04)

 

Ceev:

100000÷ (thawj txoj kab uas hla-tuab× qhov tuab)

 

qhov tuab:

Txhab tuab (1 zaug)) = pas dej qub× 0.92

Txhab tuab (2 zaug) = tus pas dej qub * 0.84

 

Inch:

Nthuav dav hla = pwm loj + nthuav tuab× 2

Pwm loj: nthuav dav txoj kab uas hla-2 * Nthuav phab ntsa tuab

Sab hauv thiab sab nraum ntawm Kos:

 

Khawb qhov tob tob: 0.2 hli, ntev: 2cm, nws yog hu ua kos. Tsis pub

Ncaj: ≤6meter, khoov yog 5 hli, ≤12Meter yog 8 hli

 

Rau kev sib txawv:

Lub raj raj qub 610 * 19 kub nthuav 660 * 16

Thawj Yeeb Ntsig Ntev: 12.84Meter

Nthuav tuab: 19 * 0.92 = 17.48 (1time)

19 * 0.84 = 15.96(2times)

Nthuav ntev ntawm cov yeeb nkab: 610 ÷ 660 * 1.04 * 12.84 = 12.341962

Nthuav dav txoj kab uas hla: 625 + 17.48 * 2 + 1 = 660.96 (1time)

625 + + 15.96 * 2 + 1 = 657.92 (2times)

 

Module Loj: 660-2 * 16 = 628
