Thaum tau txais cov nplhaib hlau rau txhua daim ntawv thov, cov teeb meem feem ntau tuaj yeem taug qab cov txheej txheem hlau. Casting rings feem ntau plagued nrog lub zog tsis zoo thiab kev ncaj ncees. Rolled thiab welded los yog txiav rings los ntawm phaj yog qhov ua rau qaug zog, thiab nqa cov khoom siv ntau dhau thiab cov nqi ua haujlwm. Lwm cov txiaj ntsig suav nrog:
1. Tswj kev taw qhia cov nplej ntws
2. Ua kom muaj zog
3. Superior structural kev ncaj ncees
4. Tshem tawm ntawm kev suav nrog thiab porosity
5. Txo cov khoom pov tseg
6. Tshem tawm cov vuam, uas txo qhov qaug zog thiab kev tawg
Muab piv rau Kub Rolled Burnout phaj
Lub unidirectional grain flow inherent nyob rau hauv kub dov phaj ua exposed grain xaus thaum txiav lub nplhaib puab. Qhov no renders cov khoom ntau lub luag hauj lwm rau qaug zog thiab ntau rhiab heev rau kev nyuaj siab corrosion cracking. Cov txheej txheem forging tsim cov khoom mus rau qhov xav tau lub nplhaib loj yog li tsis tas yuav tshem tawm cov ces kaum ntau dhau los yog qhov chaw nruab nrab. Tsis tas li ntawd, cov khoom muaj thiab cov phaj loj rau cov phaj loj loj yuav nyuaj kom tau txais. Zuag qhia tag nrho, forging tso cai rau ntau qhov ntau thiab tsawg thaum txo cov khoom pov tseg, feem ntau txo nqi.
Muab piv rau Castings
Cam khwb cia rings feem ntau tsis muaj cov qauv nplej uas xav tau. Qhov no ua rau muaj kev cuam tshuam loj heev, ductility thiab qaug zog ntawm lub nplhaib thiab tuaj yeem ua rau muaj peev xwm tawg lossis tawg. Forging muab kev tswj kev tswj cov nplej ntws los yog ua kom muaj zog thiab muaj kev ua haujlwm zoo dua qub, tshem tawm cov kev sib txuas thiab cov porosity feem ntau pom hauv castings.
Muab piv rau Rolled Thiab Welded Rings
Fabricated rings yog raug rau porosity thiab inclusions nyob rau hauv cov khoom. Kev siv dav dav ntawm lub nplhaib dov thiab welded txo qhov kev ncaj ncees, ua rau muaj kev tiv thaiv corrosion thiab tuaj yeem ua rau muaj kev cuam tshuam ntawm lub nplhaib cov duab. Nrog rau qhov tsis muaj vuam los ntawm cov txheej txheem seamless dov lub nplhaib forging, ib feem ntawm kev ncaj ncees, kev tiv thaiv corrosion, thiab cov duab tuaj yeem tswj tau ... thaum kawg ua tiav lub nplhaib muaj zog thaum txo kev pheej hmoo ntawm kev qaug zog thiab tawg.
