Yuav ua li cas Tswj Cov Kub Pouring Cov Valve Castings?

Yuav ua li cas los tswj lub qhov cub kub ntawm valve castings?

Txhua txhua xyoo nyob rau hauv qhov kev tsim tawm ntawm valve castings, feem ntau yog vim casting kub seem castings accounted rau txog 20%, casting kub yog ze rau casting zoo, yog li ntawd, los txhim kho cov qoob loo ntawm valve castings, koj yuav tsum tau tswj lub pouring kub.

1, qhov siab tshaj plaws uas kub hnyiab. Kev siab kub hnyav siab yuav ua rau cov xuab zeb zoo li nce, tshwj xeeb tshaj yog nrog cov xuab zeb cag hlau castings, thaum nchav kub 1420 thaum khwv tau nce, nchuav kub ntawm 1460 tsib hnub khib nyiab txog li 50%. Yog li ntawd, qhov siab tshaj casting yuav tsum raug tswj nyob rau hauv 1420 Shan.

2. Qhov qis tshaj kub. Thaum lub qhov cub tawg qis dua 1380 Tsib, qhov me me ntawm txhua lub monomer yuav muaj nyob hauv qhov chaw ntawm cov hlau cam hlau, thiab lub taub ntawm lub qhov taub 1. Feem ntau ntawm cov neeg muaj tsuas yog 1-2 qhov me, thiab cov qhov no kuj yuav tshwm sim nrog ib qho me me ntawm kua slag. Cov kev tshwm sim qhia tau hais tias qhov kev ntxub no muaj feem xyuam rau kev sov siab, thiab thaum lub qhov cub tawg siab siab tshaj 1380 Tsib, qhov tsis xws luag yuav tsis raug tsim tawm hauv cov yeeb yaj kiab valve.

Ua ke, nws pom tau hais tias qhov kub thiab txias yuav tsum tau tswj nyob rau hauv 1380. Tsis tas li ntawd, feem ntau yog qhov ua rau qis dej tsawg yog qhov uas ua ntej yuav nchuav, cov hlau uas tau raug thauj mus los thiab nyob hauv lub tshav poom qhib ntev ntev. Lub tshav kub tuaj yeem raug txo kom txo tau los ntawm lub hau npog nrog ib qho khoom siv adiabatic.
