Qhov sib txawv ntawm nruab nrab zaus rauv thiab electroslag remelting rauv

Qhov zaus ntawm qhov nruab nrab zaus rauv thiab lub tshuab hluav taws xob electroslag remelting qhov cub yog qhov sib txawv, thiab qhov zaus ntawm qhov nruab nrab zaus rauv yog siab dua li ntawm qhov cub hluav taws xob electroslag remelting. Lawv muaj tib lub hauv paus ntsiab lus: alternating tam sim no generates alternating magnetic teb, thiab cov hlau nyob rau hauv lub alternating magnetic teb tsim alternating induced muaj peev xwm thiab induced tam sim no, thiab cov kev taw qhia ntawm induced tam sim no yog opposite rau cov kev taw qhia ntawm tam sim no nyob rau hauv lub induction kauj. lub cub tawg. Nyob rau hauv qhov kev txiav txim ntawm induced electromotive quab yuam, cov rhuab hlau generates ib tug induced tam sim no. Thaum qhov tam sim no dhau mus, nws tsim cov cua sov kom kov yeej cov hlau tsis kam thiab ua haujlwm. Lub tshuab hluav taws xob nruab nrab siv qhov cua sov no los ua kom sov thiab yaj cov hlau kom ua tiav lub hom phiaj ntawm melting. Nws lub ntsiab nta yog raws li nram no:

1. Cov hlau molten yog raug electromagnetic quab yuam los tsim kom muaj zog nplawm. Qhov no yog ib qho tseem ceeb ntawm qhov nruab nrab zaus qhov cub. Lub zog (stirring) ntawm cov kua hlau pib los ntawm qhov chaw ntawm lub pas dej molten thiab txav mus rau ob qho kawg ntawm lub kauj. Hauv qab thiab cov phab ntsa rauv yog txwv, yog li qhov kawg txav yog ib txwm nce siab, ua ib lub hump rau saum lub pas dej ua ke.

2. Lub tshuab hluav taws xob electroslag remelting rauv yog nyob rau theem pib ntawm kev tsis sib txuas. Tag nrho cov khoom siv hlau yuav tsum tau yaj yog tsim los ntawm cov khoom me me. Vim yog txoj kev pub mis thiab lwm yam teeb meem, qhov kev them nqi tsuas yog kwv yees li 1/3 ntawm lub tshuab hluav taws xob. Lub sijhawm no, tus nqi siab heev. Nrog rau cov hluav taws xob tsis zoo, thaum lub zog nkag mus rau lub qhov cub, tus nqi ntawm tus kheej yuav pib arcing thiab raug welded ua ke. Thaum welded ua ke, tag nrho cov nqi hluav taws xob yuav tsim ib daim loj, yog li qhov ua tau zoo ntawm lub cub tawg tau txhim kho. Lub arc pib ceev ntawm ib zaug xwb nyob ntawm qhov ua tau zoo. Lub cev thiab tshuaj lom neeg cov khoom ntawm cov hlau yuav tsum tau yaj yog txawv, thiab qhov yuav tsum tau muaj zaus tsis sib haum. Qhov me me ntawm qhov me me, qhov ntau dua qhov yuav tsum tau muaj, thiab qhov ntau zaus kuj yuav ua rau lub melting ceev.
