Lub hom phiaj ntawm qhov riser hauv kev ua haujlwm yog dab tsi?
Ib riser (tseem hu ua "feeder") txuas rau cov pwm ntawm qhov chaw ntawm cov hlau molten nkag, tiv thaiv kab noj hniav los ntawm kev sib sau vim qhov shrinkage thaum lub sij hawm khov vim kawg taw tes kom solidify yog sab nraum pwm kom zoo.
Lub luag haujlwm tseem ceeb ntawm tus riser yog dab tsi?
Rau alloys nrog loj ntim shrinkage thaum lub sij hawm solidification thiab uas zoo li yuav ua rau cov concentrated shrinkage, xws li cam khwb cia hlau, manganese tooj dag, thiab txhuas bronze, lub luag hauj lwm tseem ceeb ntawm cov risers yog rau compensate cov kua shrinkage ntawm cov hlau molten nyob rau hauv kab noj hniav thiab shrinkage ntawm cov castings thaum lub sij hawm…
Kev khiav thiab riser yog dab tsi?
Khiav, rooj vag, thiab risers siv rau kev pub cov hlau molten hauv pwm kab noj hniavtuaj yeem tsim ib feem ntawm cov qauv. Cov qauv tsim kom zoo thiab ua tiav thiab du nto txo qhov tsis xws luag. Cov qauv tsim kom raug txo qis tus nqi tag nrho ntawm cov castings.
Lub hom phiaj ntawm tus riser yog dab tsi yog tus dig muag riser?
qhov muag tsis pom kev, lossis cov risers kaw, yog siv los pub ntau yam castings … Qhov muag tsis pom kev yog nyob rau hauv qis qis ntawm cov castings, los yog cia li muab zais ntawm ib theem hauv qab cov risers saum toj kawg nkaus., thiab zoo li qhib risers, lawv ua raws li cov reservoir uas muab cov kua hlau rau hauv acasting raws li nws cog lus rau solidification.
