• Cov twj tso kua mis castings thiab valves ua los ntawm zirconium, siv rau hauv kev lag luam tshuaj lom neeg thiab marine drilling, thiab lwm yam.

Lub hauv paus ntsiab lus ntawm levitation melting:

Lub tshuab cua sov VIM-HC vacuum levitation melting furnace muab cov hlau uas yuav tsum tau yaj rau hauv ib lub zog siab lossis nruab nrab alternating electric field uas tsim los ntawm lub induction coil nyob rau hauv lub tshuab nqus tsev. Lub crucible hlau txias dej ua haujlwm ua "concentrator" ntawm lub magnetic field, tsom lub zog ntawm lub magnetic field hauv lub crucible qhov ntim. Qhov no tsim cov eddy currents muaj zog ze ntawm qhov chaw ntawm lub charge, tso tawm Joule cua sov los yaj lub charge thiab tib lub sijhawm tsim lub Lorentz force field uas levitates (lossis semi-levitates) thiab do cov yaj.

Vim yog lub zog sib nqus, cov yaj raug cais tawm ntawm phab ntsa sab hauv ntawm lub crucible. Qhov no hloov pauv tus cwj pwm cua sov ntawm cov yaj thiab phab ntsa crucible los ntawm kev sib kis mus rau kev tawg, txo qhov kev poob cua sov. Qhov no tso cai rau cov yaj kom ncav cuag qhov kub siab heev (1500 ℃ -2500 ℃), ua rau nws tsim nyog rau kev yaj cov hlau uas yaj siab lossis lawv cov hlau sib xyaw.

Kev Zoo ntawm Kev Siv Tshuab:

1. Yaj
Rov yaj thiab alloying;

Degassing thiab refining;

Kev yaj tsis muaj cruise (kev yaj ntawm kev ncua);

Kev siv dua tshiab;

Kev ntxuav kom txo qis thermal, kev ntxuav thaj tsam yaj, thiab kev ntxuav distillation ntawm cov khoom siv hlau;

2. Kev Ua Casting
Kev taw qhia crystallization;

Kev loj hlob ntawm ib qho siv lead ua;

Kev ua kom zoo nkauj casting;

3. Kev Tsim Khoom Tshwj Xeeb
Nqus plua plav txuas ntxiv casting (tuav, phaj, raj);

Nqus plua plav casting (strip casting);

Kev tsim cov hmoov nqus tsev;

Kev faib tawm khoom:

* Kev ncua ntawm lub cub tawg them thaum lub sijhawm smelting zoo tiv thaiv kev sib kis ntawm kev sib cuag ntawm lub them thiab phab ntsa crucible, ua rau nws tsim nyog rau kev tau txais cov khoom siv hlau thiab cov khoom tsis yog hlau uas muaj kev ntshiab lossis muaj kev cuam tshuam ntau.

* Electromagnetic stirring ntawm cov yaj muab kev sib xyaw zoo heev thermal thiab tshuaj lom neeg.

* Kev tswj hwm qhov kub thiab txias ntawm cov khoom siv los ntawm nruab nrab lossis siab zaus tam sim no los ntawm lub kauj induction ua tiav kev tswj hwm zoo heev.

* Kub siab heev, tshaj 2500 ℃, muaj peev xwm yaj cov hlau xws li Cr, Zr, V, Hf, Nb, Mo, thiab Ta.

* Kev cua sov induction yog txoj kev cua sov uas tsis sib cuag, zam kev cuam tshuam thiab volatilization los ntawm plasma beam lossis electron beam cua sov txoj kev ntawm crucible thiab molten hlau.

* Muaj ntau yam kev ua haujlwm, suav nrog kev smelting, kev casting hauv qab, kev tilting casting, thiab kev them nqi, thiab tuaj yeem nruab nrog kev them nqi tas mus li, cov khoom siv rub billet tas mus li, thiab cov khoom siv centrifugal casting (xaiv tau).
