Kub txwv:Qhov ntsuas kub qis tshaj plaws rau S890Q yog-20 degree.
Kev tsim cov khoom: * Cold forming:Ua tiav ntawm qhov kub thiab txias hauv qab qhov siab tshaj plaws tso cai rau kev ntxhov siab-relieving kub (530℃rau 580 degree).
Kub txoj kev:Ua ntawm700℃rau 1050 degree; Txawm li cas los xij, kev rov kho dua yog qhov yuav tsum tau ua tom qab los kho cov khoom xa tuaj zoo li qub.
Txiav:Cov hlau yog combustible thiab haum rau hluav taws xob arc txiav. Rau nplaim taws txiav, preheating rau100-200 degreeyog pom zoo rau thicknesses saum toj no30 mmlos xyuas kom meej qhov txias crack kuj.
Fabrication thiab Vuam
Preheating:Preheating (100-200 degree) raug pom zoo yog tias qhov kub ntawm qhov chaw ua haujlwm qis dua5 degreelos yog yog hais tias thermal txiav npoo yuav tsum txias - tsim thaum lub sij hawm tom qab ua.
Txoj Cai Ua Raws Cai:Cov hlau yog tsim nyog- kuaj rau kev tsim cov hlab ntsha thiab cov kav dej siab raws li German cov cai
Cov ntawv thov tseem ceeb
S890Q yog tsim los rau kev xav tau ib puag ncig uas muaj kev thauj khoom siab -cov kabmob muaj peev xwm thiab qhov hnyav txo yog qhov tseem ceeb:
Heavy Machinery:Lifting thiab mining khoom.
Kev thauj mus los:Siab - cov khoom siv kev ntxhov siab rau cov tsheb hnyav - lub luag haujlwm.
Kev tsim kho:Tshwj xeeb siab -loaded steel kev tsim kho thiab siab- hais txog infrastructure.
