Hauj lwm lawm
Lower pressure casting riser raj yog ib qho ntawm cov khoom tseem ceeb ntawm lub tshuab tsis tshua muaj siab casting. Thaum lub sij hawm tuag-casting txheej txheem, cov txhuas yaj (kub 700 ~ 900 degree) yog pressed los ntawm cov yeeb nkab riser mus rau pwm kab noj hniav txhua 3 mus rau 5 feeb.
Cov yeeb nkab steel riser yog siv rau hauv cov txheej txheem ntau lawm. Vim tsis zoo thermal poob siab tsis kam, tsis zoo corrosion kuj, luv luv kev pab cuam lub neej thiab nquag hloov, nws tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov khoom siv tas mus li thiab zoo. Silicon nitride riser raj tau dhau los ua cov khoom siv zoo tshaj plaws rau kev npaj qis qis casting riser raj vim nws tsis tshua muaj thermal expansion, zoo thermal shock resistance, thiab tsis-stick aluminium.
