1. Slag tshem tawm ntawmgraphite crucible
Txoj kev tsis ncaj ncees lawm: cov khoom seem nyob hauv lub crucible yuav nkag mus rau phab ntsa crucible thiab corrode lub crucible, yog li shortening lub neej ntawm crucible.
Txoj kev kom raug: Koj yuav tsum siv lub shovel steel nrog lub tiaj tiaj hauv qab txhua hnub kom ua tib zoo khawb tawm cov seem ntawm phab ntsa sab hauv ntawm lub crucible.
2. Lub khoob ntawm graphite crucible
Txoj kev tsis ncaj ncees lawm: dai lub kub crucible tawm ntawm lub cub tawg thiab muab tso rau ntawm cov xuab zeb, cov xuab zeb yuav hnov mob nrog glaze txheej ntawm crucible rau daim slag;cov kua hlau residual yuav solidify nyob rau hauv lub crucible tom qab lub crucible raug kaw, thiab cov hlau yuav melted thaum lub sij hawm tom ntej cua sov.Lub expansion yuav tawg lub crucible.
Txoj kev raug: tom qab lub kub crucible raug tshem tawm ntawm lub cub tawg, nws yuav tsum tau muab tso rau ntawm ib tug high-temperature resistant phaj, los yog tshem tawm ntawm ib tug hloov lwm lub tsev twj;Thaum cov khoom raug cuam tshuam los ntawm lub cub tawg lossis lwm yam teeb meem, cov kua hlau yuav tsum tau muab nchuav rau hauv pwm (me me ingot pwm) los tsim cov ingot ingots, vim cov ingots me me tuaj yeem rov qab siv tau yooj yim dua.Cov kev ceev faj:
Tsis txhob cia cov kua hlau seem khov rau hauv lub crucible.Nws muaj peev xwm muab pov tseg cov kua thiab nqa tawm slag tu thaum hloov pauv.
Yog hais tias cov kua hlau solidifies nyob rau hauv lub crucible, thaum reheated, cov hlau expanding yuav tawg lub crucible, tej zaum kuj tawg rau hauv qab ntawm lub crucible tag nrho.
