Kev npaj Billet thiab cua sov

 

Kev xaiv Billet: Ua ntej, nws yog ib qho tseem ceeb uas yuav tau xaiv cov khoom tsim nyog los ua cov pob zeb dov. Qhov zoo ntawm cov pob zeb casting yog qhov tseem ceeb heev rau cov txheej txheem dov tom ntej thiab kev ua haujlwm ntawm cov khoom kawg. Rau siab-lub zog shipbuilding steel daim hlau, lub casting billets yuav tsum muaj zoo zoo sab hauv, nrog rau sab hauv porosity, blowholes thiab lwm yam tsis xws luag minimized. Vim tias cov teeb meem no tuaj yeem nthuav dav thaum lub sijhawm dov thiab cuam tshuam rau kev ua haujlwm ntawm cov hlau.

 

Lub hom phiaj ntawm kev tswj cua sov thiab ntsuas kub: Cov billets yuav tsum tau ua kom sov ua ntej nkag mus rau hauv lub tshuab dov. Lub hom phiaj tseem ceeb ntawm cov cua sov yog los txo qhov deformation tsis kam ntawm cov billets, ua rau cov txheej txheem dov smoother, thiab ua kom cov qauv billet zoo ib yam. Cov cua kub feem ntau yog nyob ib ncig ntawm 1100 - 1250 degree . Nyob rau hauv qhov ntsuas kub no, cov nplej hauv cov pob zeb yuav maj mam loj tuaj thiab ua kom zoo dua qub. Yog tias cov cua kub qis dhau lawm, qhov deformation tsis kam ntawm cov billets yuav siab heev, uas yuav ua rau muaj kev nyuaj ntawm dov thiab tej zaum yuav ua rau cov hlau tsis zoo tom qab dov. Yog tias qhov kub thiab txias siab dhau lawm, cov teeb meem xws li dhau - hlawv thiab decarburization ntawm daim tawv nqaij yuav tshwm sim, cuam tshuam rau cov hlau zoo. Thaum cov txheej txheem cua sov, cov cua kub yuav tsum tau tswj nruj me ntsis kom tsis txhob muaj qhov sib txawv ntawm qhov kub thiab txias ntawm qhov chaw sab hauv thiab sab hauv ntawm cov billets vim yog overheating, uas yuav ua rau muaj kev ntxhov siab thermal thiab ua rau muaj kev puas tsuaj xws li tawg. Segmented cua sov thiab lwm yam kev siv feem ntau yog siv los tswj tus nqi cua sov.
