Taw qhia txog hom hluav taws xob rauv taws

Industrial resistance rauv
② Vim yog qhov me me ntawm cov khoom siv nws tus kheej, txhawm rau ua tiav qhov xav tau hluav taws xob cua sov, qhov ua haujlwm tam sim no loj heev, yog li lub zog xa hluav taws xob thiab cov khoom siv yuav tsum nyob rau hauv kev sib cuag zoo kom tsis txhob arcing thiab hlawv cov khoom, thiab qhov kev tiv thaiv ntawm lub tsheb npav fais fab yuav tsum yog me me kom txo tau qhov hluav taws xob poob; Feem ntau cov cua sov ua kom sov yog cov cua sov tsis ncaj rau cov cua sov, uas tau nruab nrog cov resistor tshwj xeeb tsim los ua kom tau hluav taws xob hloov hluav taws xob, hu ua hluav taws xob rhaub, uas hloov hluav taws xob hluav taws xob rau cov khoom siv hauv lub cub tawg.
Lub plhaub ntawm lub qhov cub hluav taws xob no yog ua los ntawm cov phaj steel, thiab lub qhov cub yog lined nrog cov ntaub ntawv refractory xws li ceramics fibers, nrog cov ntaub ntawv tso rau hauv.
Cov khoom siv cua sov feem ntau yog hlau chromium aluminium cua sov cov ntsiab lus, nickel chromium cua sov ntsiab lus, silicon carbide rods, molybdenum disilicide rods, thiab silicon carbon rods, zirconium diboride ceramic composite cua sov ntsiab lus. Raws li kev xav tau, cov cua hauv qhov cub tuaj yeem yog qhov chaw zoo tib yam, tiv thaiv huab cua, lossis lub tshuab nqus tsev. Lub zog hluav taws xob dav dav yog 220 V lossis 380 V. Yog tias tsim nyog, ib qho kev hloov pauv nruab nrab nrog qhov hloov tau qhov hluav taws xob tau teeb tsa. Qhov cub me me (<10 kW) single-phase power supply, large furnace three-phase power supply. For materials with a single variety and a large batch size, continuous furnace heating should be used. For resistance furnaces with furnace temperatures below 700 □, most are equipped with blowers to enhance heat transfer in the furnace and ensure uniform heating. Resistance furnaces for melting fusible metals (lead, lead bismuth alloys, aluminum, magnesium, and their alloys) can be made into crucible furnaces; Or it can be made into a reverberatory furnace with a molten pool, and an electric heating body is installed on the top of the furnace. Electroslag furnace is a resistance furnace that realizes electrothermal transformation by dissolving slag (see Electroslag Remelting).
