Cov neeg ua haujlwm cuam tshuam hauv kev lag luam steelmaking paub tias ferromolybdenum yog siv los ua cov khoom siv hlau ntxiv hauv steelmaking, uas tuaj yeem txhim kho cov tawv tawv ntawm cov hlau thiab pab tshem tawm kev npau taws. Ib qho tseem ceeb raw khoom hauv steelmaking, molybdenum yog ntxiv rau cam khwb cia hlau kom nws lub zog thiab hnav tsis kam. Nws hloov tawm tias ferromolybdenum muaj ntau txoj haujlwm, yog li cia peb saib nws cov smelting rau koj siv.
Cov khoom siv raw rau smelting ferromolybdenum feem ntau yog molybdenite (MoS2). Ua ntej smelting, molybdenum concentrate feem ntau yog oxidized thiab roasted nyob rau hauv ib tug multi-hearth cub kom tau roasted molybdenum ore nrog ib tug sulfur ntsiab lus ntawm tsawg tshaj li 0.07%. Ferromolybdenum smelting feem ntau siv cov txheej txheem sab nraud. Lub tshuab hluav taws xob yog lub tog raj kheej tso rau ntawm cov xuab zeb hauv paus, kab nrog av nplaum cib, thiab siv ferrosilicon uas muaj 75% silicon thiab ib qho me me ntawm txhuas cov khoom ua tus neeg sawv cev txo.
Tom qab tus nqi ntxiv rau hauv lub qhov cub hluav taws xob ib zaug, nws yog smelted los ntawm txoj kev ignition sab sauv. Siv tus pib (saltpeter, aluminium chips lossis magnesium chips) ntawm cov khoom siv. Tom qab hluav taws kub hnyiab, nws yuav hnov mob hnyav, tom qab ntawd txias, tso slag, thiab tshem tawm lub tshuab hluav taws xob. Cov ferromolybdenum ingots yog thawj zaug txias hauv cov xuab zeb zes, thiab ces xa mus rau chav txias kom yaug nrog dej kom txias, crushing thiab ua tiav.
