Cov haujlwm ntawm ferroalloys tsuas yog suav nrog cov hauv qab no:
Nqe Nrhiav Nrhiav tau: Kev ua lag luam Ferrroalloy futures kev cia siab rau cov nqi tom ntej ntawm ntau tus neeg koom nrog cov neeg tsim khoom lag luam, cov tub luam thiab cov tub ua lag luam.
Hedging: ferrroalloy futures muaj kev ua haujlwm ntawm hedging. Rau cov ferrroalloy manufacturers thiab cov neeg siv khoom, los ntawm hedging hauv kev ua lag luam yav tom ntej, lawv tuaj yeem xauv cov nqi lossis cov txiaj ntsig kev ua haujlwm.
Kev Ua Si: Ferrroalloy Futures muaj kev ua tiav siab, uas txhais tau tias cov tub ua lag luam tuaj yeem yuav lossis muag cog lus cog lus ntau dua, yog li paub cov peev txheej faib thiab kev tswj hwm kev pheej hmoo.
Deagidizer: Hauv cov txheej txheem statmaking, ferrroalloys tuaj yeem siv los ua deoxidizers tshem oxygen los ntawm Molten hlau. Qee cov ferroalloys kuj tseem tuaj yeem tshem tawm lwm cov impurities nyob rau hauv cov hlau xws li cov leej faj thiab nitrogen.
Alloy Ntxiv: Raws li kev muaj pes tsawg ntawm cov kev cai ntawm tus qauv steel, ferrroalloys tuaj yeem txuas ntxiv rau kev ua tau zoo ntawm cov hlau, xws li kev txhim kho hardness, nruj thiab hnav tsis kam.
Inoculant: ntxiv rau hauv molten hlau ua ntej caming los txhim kho cov qauv siv lead ua ntawm lub pov.
Txo tus neeg sawv cev: hauv cov txheej txheem metallurgical, ferrroalloys tuaj yeem siv los ua cov neeg sawv cev thiab deoxidizers txhawm rau txhim kho cov kev sib tw metallgical, nce ntau lawm thiab txo tus nqi.
Kev Lag Luam Hluav Taws Xob: Cov Khoom Chromium, Cobalt, thiab Vanadium Hauv Cov Khoom Siv Hluav Taws Xob, thiab siv tau cov khoom siv hluav taws xob, muaj zog sib nqus, hluav taws xob cua sov alloys, thiab lwm yam.
