Lub chaw kuaj hluav taws xob cub hluav taws xob yog qhov hluav taws xob tsis ncaj qha hluav taws xob

Feem ntau cov hluav taws kub tsis kam yog cov cua sov tsis ncaj rau cov cua sov, uas tau nruab nrog lub cev resistor tshwj xeeb uas siv los paub txog kev hloov hluav taws xob hluav taws xob, hu ua hluav taws xob cua sov lub cev, uas hloov hluav taws xob hluav taws xob mus rau cov ntaub ntawv hauv qhov cub. Lub plhaub ntawm lub qhov cub hluav taws xob no yog ua los ntawm steel phaj, lub hearth yog lined nrog cov ntaub ntawv refractory, thiab cov ntaub ntawv muab tso rau hauv. Cov khoom siv hluav taws xob feem ntau siv yog hlau-chromium-aluminium electric heaters, nickel-chromium electric heaters, silicon carbide rods thiab molybdenum disilicide rods. Raws li kev xav tau, cov cua hauv qhov cub tuaj yeem yog qhov cua zoo tib yam, tiv thaiv huab cua lossis lub tshuab nqus tsev. Feem ntau, lub hwj chim mov voltage yog 220 volts los yog 380 volts, thiab ib tug nruab nrab transformer nrog adjustable voltage yuav tsum tau nruab yog tsim nyog. Ib-theem fais fab mov rau cov cub tawg me me (<10 kW) and three-phase power supply for large furnaces. For materials with single varieties and large batches, continuous furnace heating should be used. Most resistance furnaces with furnace temperature lower than 700 □ are equipped with blowers to strengthen heat transfer in the furnace and ensure uniform heating.

Thaum cua sov hauv chav kuaj hluav taws xob rauv, koj yuav tsum xyuam xim rau:

① Txhawm rau kom sov cov khoom sib xws, cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob ntawm txhua qhov ntawm cov khoom yuav tsum ua kom zoo ib yam; ②Vim qhov tsis kam ntawm cov khoom nws tus kheej yog me me, qhov ua haujlwm tam sim no loj heev kom ua tiav lub zog hluav taws xob uas xav tau, yog li cov khoom siv hluav taws xob thiab cov khoom siv yuav tsum nyob rau hauv kev sib cuag zoo Arcing hlawv cov ntaub ntawv, thiab lub zog tiv thaiv. kis tau tus mob yuav tsum me me kom txo tau qhov hluav taws xob poob; ③Thaum muab lub zog AC, lub network luv yuav tsum tau teeb tsa tsim nyog kom tsis txhob muaj qhov inductance ntau dhau thiab tsis muaj zog.

Nyob rau hauv cov cua sov ncaj qha mus kuaj qhov cub, qhov tam sim no kis ncaj qha los ntawm cov khoom siv. Vim hais tias cov hluav taws xob cua sov lub zog yog concentrated nyob rau hauv cov khoom nws tus kheej, cov khoom yog rhuab sai sai, uas yog haum rau cov txheej txheem uas yuav tsum tau ceev cua sov, xws li cua sov forging blanks. Qhov zoo ntawm qhov cub hluav taws xob no tuaj yeem ua kom sov cov khoom mus rau qhov kub siab heev. Piv txwv li, cov khoom siv hluav taws xob graphitization hluav taws xob tuaj yeem ua kom sov cov khoom rau ntau tshaj 2500 □. Lub qhov hluav taws xob hluav taws xob ncaj qha tuaj yeem ua rau hauv lub tshuab nqus tsev cua sov los yog lub tshuab hluav taws xob tiv thaiv cua sov. Nyob rau hauv hmoov metallurgy, nws yog feem ntau siv rau sintering tungsten, tantalum, niobium thiab lwm yam khoom.
