Aluminium boron master alloy AlB8
Aluminium borontswv alloyAlB8
Master alloys yog cov khoom semi-tiav lawm, thiab tuaj yeem tsim nyob rau hauv cov duab sib txawv. Lawv yog pre-alloyed sib tov ntawm alloying ntsiab. Lawv kuj tseem hu ua modifiers, hardeners, lossis grain refiners raws li lawv daim ntawv thov. Lawv tau ntxiv rau yaj kom ua tiav qhov tshwm sim tsis zoo. Lawv tau siv los hloov cov hlau ntshiab vim tias lawv siv nyiaj ntau heev thiab txuag lub zog thiab lub sijhawm ntau lawm.
Al-B master alloy siv rau grain refining ntawm casting Aluminium alloys thiab rau purification ntawm EC qib Aluminium alloys. Peb cov neeg siv khoom Iran kuj sivAl-8Bmaster alloy hauv cov tub ntxhais sib txuas rau ACCC (Aluminium conductor composite core) cables.

| Daim ntawv thov | 1. Hardeners: Siv los txhim kho lub cev thiab lub zog ntawm cov hlau alloys. 2. Grain Refiners: Siv rau kev tswj cov dispersion ntawm ib tug neeg muaju nyob rau hauv cov hlau los tsim ib tug finer thiab ntau uniform grain qauv. 3. Modifiers & Tshwj xeeb Alloys: Feem ntau yog siv los ua kom muaj zog, ductility thiab machinability. | ||||||||||

Kev tsim khoom:
Raw khoom xaiv & proportioning → melting → thawj refining → alloying → particles generation controlling → on-line testing & analyzing → morphology regulating of particles → thib ob refining → functional test → casting → final test → kawg khoom
