2. Steelmaking: Deoxidization thiab Desulfurization​

Hauv kev tsim cov hlau,calcium carbideua apurification tus neeg sawv cev, tshem tawm cov pa oxygen thiab sulfur impurities los ntawm cov hlau molten los ua cov hlau zoo - zoo.

Mechanism​

Deoxidization: Reacts nrog oxygen hauv molten steel los tsim calcium oxide (CaO) thiab carbon monoxide (CO), txo cov porosity thiab tsis muaj zog.

Desulfurization: khi nrog sulfur los tsim calcium sulfide (CaS), uas ntab mus rau saum npoo li slag thiab yog skimmed tawm.

Kev cuam tshuam rau Steel Quality​

Txhim kho tensile lub zog, ductility, thiab corrosion kuj.

Tiv thaiv qhov tsis xws luag xws li kub luv ( brittleness ntawm qhov kub thiab txias) thiab porosity.

Kev lag luam nyob ntawm qhov kev siv no​

Automotive (tsheb ncej, cav qhov chaw).

Kev tsim kho (reinforcement bars, structural steel).

Manufacturing (cov cuab yeej, khoom siv, machinery).

3. Chemical Manufacturing: Feedstock for Plastics and Solvents​

Acetylene muab tau los ntawm calcium carbide yog lub hauv paus raw khoom rau kev tsim cov tshuaj muaj:

Cov tshuaj tseem ceeb tsim tawm​

Vinyl Chloride: Monomer rau polyvinyl chloride (PVC), siv nyob rau hauv cov kav dej, cables, flooring, thiab ntim.

Acetic acid: Siv nyob rau hauv vinegar, adhesives, textiles, thiab pharmaceuticals.

Synthetic Roj Hmab: Neoprene thiab nitrile roj hmab rau cov log tsheb, cov ntsaws ruaj ruaj, thiab cov hoses muaj.

Ethylene Glycol: Ib qho precursor rau antifreeze thiab polyester fibers.

Kev lag luam tseem ceeb​

Tshaj li 70% ntawm lub ntiaj teb no acetylene ntau lawm rau tshuaj cia siab rau calcium carbide.

Txhawb $ 500 billion + plastics thiab petrochemicals kev lag luam.

4. Hlau Fabrication: Brazing thiab Soldering​

Calcium carbide-tsim acetylene yog siv rau hauvbrazing(sib koom hlau nrog cov khoom muab tub lim) thiabsoldering​ (kev sib txuas cov hlau nrog qis- melting- taw tes alloys).

Koom nrog cov kav dej tooj liab hauv HVAC systems.

Kho cov khoom siv txhuas thiab tooj dag hauv tshuab.

Fabricating hniav nyiaj hniav kub thiab precision ntsuas.

Qhov zoo​

Precise cua sov tswj rau kev ua haujlwm me me.

Ntxuav, muaj zog pob qij txha tsis ua puas lub hauv paus hlau.

5. Mining thiab Tunneling: Carbide Teeb thiab tawg​

Keeb kwm, calcium carbide tau siv hauvcarbide teebrau miners thiab tunnel neeg ua hauj lwm, muab portable teeb nyob rau hauv qhov tsaus ntuj nti. Thaum LEDs tau hloov lawv nyob rau hauv feem ntau mines, carbide teeb tseem ceeb heev rau:

Teeb pom kev kub ntxhov: Kev cawm hauv qhov tsua, hluav taws xob hluav taws xob, thiab kev puas tsuaj.

Tshawb nrhiav chaw taws teeb: Kev nthuav dav hauv thaj chaw tsis muaj hluav taws xob.

Secondary Siv hauv Mining​

Calcium carbide kuj tseem siv los tsimcalcium cyanamide(CaCN₂), ib qho chiv thiab tshuaj tua kab mob siv rau kuv cov av rau kev rov kho dua.

6. Kev kho dej khib nyiab​
