Cov khoom siv

1. Hlau thiab hlau Smelting: Cov tub ntxhais ntawm Deoxidation thiab Alloying

Raws li lub zog deoxidizer:Silicon muaj qhov sib txuam zoo heev rau cov pa oxygen hauv cov hlau molten, sai sai ua kom tsawg - melting -point SiO₂ (silicon dioxide) uas ntab mus rau slag, txo cov pa oxygen hauv cov hlau, tshem tawm cov npuas thiab porosity tsis xws luag, thiab txhim kho cov purity ntawm cov hlau. FeSi75%, vim nws cov ntsiab lus silicon ntau dua, muaj qhov ua tau zoo dua deoxidation.

Raws li ib qho tseem ceeb alloying ntsiab:Silicon tuaj yeem yaj hauv ferrite, ua kom muaj txiaj ntsig tseem ceeb hauv kev txhim kho cov nyhuv. Nws yog qhov tseem ceeb hauv cov qib steel hauv qab no:

Caij nplooj ntoos hlav steel:Txhim kho elastic txwv thiab qaug zog tiv thaiv.

FAQ

Q1: Dab tsi yog qhov txawv ntawm FeSi75-A thiab FeSi75-B?

A1: Qhov tseem ceeb sib txawv yog nyob rau theem ntawm impurity cov ntsiab lus tswj. FeSi75-A muaj kev txwv nruj rau cov impurities xws li txhuas, calcium, carbon, thiab phosphorus, ua rau nws "siab-purity" ferrosilicon, thiab nws cov nqi feem ntau yog siab dua. Nws yog tsuas yog siv nyob rau hauv daim ntawv thov uas tsis tshua muaj siab purity ntawm steel yuav tsum tau. FeSi75-B yog cov hom phiaj dav dav, haum rau feem ntau deoxidation thiab casting scenarios, thiab muab cov nqi zoo dua.

Q2: Vim li cas ferrosilicon inoculant "tso" hauv casting? Yuav hais li cas txog qhov no?

A2:Inoculant poob yog hais txog qhov tshwm sim uas cov nyhuv ntawm ferrosilicon hauv kev txhawb nqa graphite nucleation tsis muaj zog nyob rau lub sijhawm tom qab ntxiv rau cov hlau molten. Qhov laj thawj tseem ceeb yog vim li cas cov inoculum nuclei (xws li SiO₂) yaj los yog ntab mus rau saum npoo ntawm qhov kub ntawm - kub molten hlau.

Cov kev ntsuas muaj xws li:

① Siv "nyob rau hauv- ntws inoculation" (ntxiv ib txhij thaum casting) kom luv lub sij hawm cov tshuaj tiv thaiv;

② Xaiv cov inoculants uas muaj cov khoom siv ntev ntev xws li barium (Ba) thiab strontium (Sr);
