Yog vim li cas rau qhov to ntawm induction melting rauv

Ib qho xwm txheej tshwm sim nyob rau hauv lub cub tawg lub cev ntawm lub qhov cub induction melting yog los ntawm lub qhov cub. Yog tias muaj kev sib tsoo, yog tias tsis muaj kev ntsuas, nws yuav ua rau lub raj tooj liab ntawm lub coil tawg, thiab cov hlau molten thiab cov coolant yuav tawg. s vim:

1. Cov yam ntxwv zoo ntawm cov ntaub ntawv siv rau hauv qhov cub tsim: feem ntau siv quartz acid rauv cov ntaub ntawv hauv ob sab phlu. Cov ntsiab lus silicon ntawm quartz xuab zeb thiab quartz hmoov yuav tsum siab tshaj 99.5%, nrog oily crystals, pob tshab thiab tsis muaj impurities. Feem ntau siv high-purity quartz xuab zeb (silicon ntsiab lus 99.85%, hardness 8, ceev 2.65, refractoriness 1850 degrees).

2. Cov khoom siv hluav taws xob siv rau hauv qhov cub siv hluav taws xob: cov txheej txheem kev tsim kho ntawm lub tshuab hluav taws xob feem ntau siv cov boric acid ua cov ntawv khi. Boric acid muaj ob qho zoo thiab qhov tsis zoo: qhov zoo yog qhov kev sib txuas ceev ceev ntawm qhov kub thiab txias, feem ntau pib ntawm 600-700 degrees; qhov tsis zoo yog tias nws tsis tuaj yeem tiv taus kub thiab yaig. Nyob rau hauv qhov kub thiab txias, qhov qis ntawm phab ntsa ntawm lub cub tawg yuav ua rau lub phenomenon ntawm boiling, tus naj npawb ntawm heats siv yog heev txo. Nws raug nquahu kom siv boric acid ua cov ntawv khi, vim tias boric acid muaj cov yam ntxwv ntawm kev sib txuas ntawm qhov kub thiab txias, siab melting point, kub tsis kam, thiab corrosion kuj.
