- Hlau Hlau Production:
Silicon-manganesealloy kuj tseem ceeb heev rau kev tsim cov hlau hlau (ductile hlau). Nws pab tswj kev tsim cov graphite, tsim cov hlau ntau dua thiab cov tawv tawv, uas yog qhov tseem ceeb rau kev tsim cov khoom uas yuav tsum tau muaj kev cuam tshuam thiab toughness.
- Daim ntawv thov piv txwv:
- Cav Cheebtsam
- Cov kav dej thiab fittings
- Cov cuab yeej siv tshuab
3. Vuam electrode manufacturing
- Alloying cov ntsiab lus hauv electrodes:
Silico-manganese alloy yog siv los tsim cov vuam electrodes. Nws yog siv los ua cov khoom siv hlau hauv electrode coatings kom muaj zog thiab hardness ntawm vuam hlau. Qhov no ua rau muaj zog thiab ruaj khov welds uas yog qhov tseem ceeb rau ntau yam kev siv vuam hauv kev lag luam xws li kev tsim kho, tsheb thiab nkoj tsim.
- Txhim kho weldability:
Lub xub ntiag ntawm silicomanganese alloys kuj txhim khu lub weldability ntawm vuam electrodes, ua rau lawv yooj yim rau siv thiab ua tau zoo dua welds. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau hauv kev lag luam uas yuav tsum tau muaj qhov tseeb thiab txhim khu kev qha vuam.
- Piv txwv daim ntawv thov:
- Steel qauv thiab txuas hniav
- Automotive thiab marine vuam
- Cov cuab yeej siv kho vaj tse
4. Ferroalloy ntau lawm
- Ib qho tseem ceeb ntawm ferroalloys:
Silico-manganesealloys yog siv los tsim ntau yam ferroalloys uas yog qhov tseem ceeb rau cov txheej txheem alloying hauv steel manufacturing. Nws ua ke nrog lwm cov hlau los tsim cov alloys uas txhim khu cov khoom ntawm cov hlau thiab lwm yam hlau. Cov ferroalloys no yog qhov tseem ceeb rau kev tsim cov hlau zoo nrog cov khoom tshwj xeeb rau kev siv sib txawv.
- Daim ntawv thov piv txwv:
- Stainless hlau ntau lawm
- Ferromanganese alloys
- High zog steel alloys
5. Kev lag luam tshuaj
- Catalyst ntau lawm:
Silico-manganese alloys yog siv rau hauv kev lag luam chemical ua catalysts rau ntau yam tshuaj tiv thaiv. Lawv cov khoom ua rau lawv tsim nyog rau cov txheej txheem uas yuav tsum muaj cov manganese thiab silicon los pab txhawb cov tshuaj tiv thaiv thiab ua kom cov txheej txheem ua haujlwm tau zoo.
- Piv txwv daim ntawv thov:
- Kev tsim cov tshuaj hluavtaws thiab cov polymers.
- Petrochemical refining txheej txheem.
- Kev tsim cov pigments thiab dyes.
