Thermite vuam: technology. Xyaum thermite nyob rau hauv lub tsev thiab nyob rau hauv qhov hluav taws xob kev lag luam

Vuam ua hauj lwm, cov khoom tsis hais txog ntawm lub tshuab siv yog nrog los ntawm yuav tsum es puab workflow. Master yog los npaj cov khoom, consumables, raws li zoo raws li saib xyuas kev ruaj ntseg. Yog li ntawd nws yog tsim nyog los noj mus rau hauv tus account tus nqi rau kev ua ub no raws li nyiaj txiag rau tej kev ua hauj lwm nyob rau hauv cov kev hom tsis yeej ib txwm nrhiav pov thawj rau qhov zoo ntawm cov kev tshwm sim. Nyob rau hauv no hais txog, ib tug ntawm cov feem ntau ib qho kev zoo yog cov thermite welding, uas yog ib qho yooj yim ua, nyob rau ntawm cov ntaub ntawv thiab nyob rau hauv tej rooj plaub tso cai rau peb mus cuag siab zog pob qij txha.

technology nta

Tus kab npaug vuam txoj kev yog yus muaj los ntawm kev siv tshwj xeeb hmoov mixtures uas thaum lub sij hawm combustion emit loj nyiaj ntawm tshav kub. Raws li ib tug txoj cai, nws yog ib tug sib tov ntawm hlau, uas yog hu los ntawm kab-rwg. Tsoos ua ke yuav siv cov ob lub Cheebtsam - lub ignition loj thiab muaj pes tsawg leeg, los ntawm uas thaum tshav kub kub yog tso tawm. Raws li cov oxide teev protrudes los ntawm hlau thiab yog ib tug loj activator ntawm tus kab npaug uas muaj magnesium thiab txhuas. Tsis tas li ntawd, thermite vuam txheej txheem tso cai rau kev siv ntawm oxides ntawm chromium, tungsten thiab npib tsib xee. Vim hais tias ntawm cov hmoov yog tiav los ntawm kev ntxiv zog rau thaum tshav kub kub. Yog li, yog tias ib tug sib tov ntawm txhuas thiab magnesium muab warmth txog 2500 ° C, tus compositions ntawm chromed kub twb tsa mus rau 3500 ° C. Txawv thiab fuse lub sib tov. Feem ntau cov qauv rau qhov teeb meem no yog ib tug ua ke ntawm magnesium, sodium thiab barium peroxide. Qhov tshwj xeeb nta ntawm lub hlawv thermite muaj xws li kev tswj active kub txawm nyob rau hauv kev sib cuag nrog dej. Nyob rau hauv lwm yam lus, lub sib tov yog suab tsis yooj yim sua tua lo cuam tshuam.

Hom thermite vuam

Muaj plaub lub ntsiab ua tau zoo xws vuam hom kev kawm - los ntawm nruab nrab molding, ua ke, thiab abutting ob lub tsev. Thaum lub sij hawm lub lag luam lub intermediate molding cov hmoov sib tov rau hauv ib lub xeev ntawm cov kua hlau, thiab qhov no tsis cuam tshuam rau starting yam ntxwv ntawm lub active tshuaj tus kab npaug. Feem ntau cov txheej txheem no yog siv rau cov mounting kho vajtse, uas yog pre-mounted nyob rau hauv txoj hauj lwm. Tshwj xeeb rau cov khoom uas muaj ib tug phaj, cathode thiab ntws terminals siv thermite taub qab vuam, rau cov uas pre-tov yog raug rho tawm haujlwm nyob rau hauv ib qhov cub. Ua ke cov txheej txheem yuav ua ke nrog ntawm ib tug txhaj txoj kev thiab taub qab vuam. Hais tias yog, tus tswv yuav ua tau yooj yim ua hauj lwm siv kua Fusing, thiab cov ntug modifying ilv ntawm taub qab vuam. Nrog kev xav txog cov duplex, qhov no txoj kev muab rau cov kev taw qhia ntawm ib tug ntxiv cov kauj ruam, nyob rau hauv uas lub molding yog ua los ntawm fused tsim kis.

siv cov khoom

Lub hauv paus ntawm cov zaub uas cov crucible, uas tso cai rau lub lag luam ntawm kab-rwg, xws li nws yog los npliag thiab cov molten hlau loj. Lub caij no tej zaum yuav ua los ntawm tej hub los yog tungsten nyob rau hauv lub qhov yuav tsum tau kub tsoom fwv. Nyias npaj thiab molds. Tshwj xeeb matrix tso cai rau koj mus ua hauj lwm nrog ib tug ntau yam ntawm molten hauv paus. Nws yuav tsum tau npaj rau thermite vuam cov khoom nyob rau hauv daim ntawv ntawm clamping thiab kho pab kiag li lawm rau loj heev designs, ib tug tshwj xeeb cutter thiab kev mem hluav tsim los rau no hom ntawm cov lag luam. Nyob ntawm seb cov ua hauj lwm tej yam kev mob thiab kev kawm ntawv uas yuav tsum tau yuav tsum tau ib tug tshwj xeeb burner rau lub inverter thiab ib tug pas ntsuas kub.

Xyaum Ua hauj lwm nyob rau hauv tsev

Nyob rau hauv lub domestic kev khwv nyiaj txiag, qhov no zoo ntawm vuam cawm cov uas yuav tsis zoo siv cov qauv ntawm cov hluav taws xob los yog roj kev twb kev txuas qhuav. Feem ntau nyob rau hauv xws li mob, ib tug tus kab npaug nrog ib tug tsawg kawg nkaus kub - txog 1300 ° C. Qhov no hom pub rau tej yam yooj yim txhuas muaj pes tsawg leeg, uas tej zaum yuav ua tau vim kho me kab nrib pleb nyob rau hauv hlau lug, ua hauj lwm los yog siv avtoslesarnye weld qhov cuab lub zog siv. Raws li ib tug txoj cai, thermite vuam yog ua nyob rau ntawm lub tsev tsis muaj tshwj xeeb inverters. Ua hauj lwm cov cuab tam yuav ua thermite mem hluav, yog tias leej twg adroitly, uas nws yog tau mus cuag ib tug ruaj kev twb kev txuas.

Xyaum ua hauj lwm nyob rau hauv industrial tej yam kev mob

Muaj koom haum ntawm tus txheej txheem ntawm Vuam nrog thermite mixtures muaj ntau qhov sib txawv. Ua ntej ntawm tag nrho cov, nws yuav siv ntau npaum hlau tebchaw nrog high tshav kub. Kab-rwg yog tib yam nrog rau lub xam nrog ntawm chromium, tungsten thiab lwm yam hais nrog active combustion muaj nuj nqi. Rau cov kev koom haum ntawm tus txheej txheem kuj yuav tsum tau siv los ntawm ntau haib khoom, xws li ib tug thermite mem hluav kws txawj yog tsis txwv. Piv txwv li, thermite vuam nyob rau hauv qhov hluav taws xob kev lag luam tas yuav siv cov inverters, kom tshuab nrov tuaj, thiab lwm yam khoom, uas tso cai rau yuav tau taug qab qhov workflow chaw. Qhov thib peb feature ntawm lub vuam nyob rau hauv lag luam - yog npaj ib tug tshwj xeeb tuav SNAP qhia. Siv foundry refractory ntaub ntawv sau khoob, siab crucible tuav tseg thiab clamps rau txawv designs.

Nta vuam nyob ntawm tej

thermite vuam txheej txheem ua hauj lwm zoo tshaj plaws rau kev ua hauj lwm nrog hluav taws xob thaiv. Ntxiv mus, qhov no mus kom ze yuav siv tau ob qho tib si nyob rau hauv kev lag luam thiab nyob rau hauv lub tsev. Thaum lub sij hawm ua hauj lwm-hlau compound xov tsim txoj. Nws yog ib qho tseem ceeb kom nco ntsoov tias txo txheeb ze rau qhov seem ntawm cov khoom nyob rau hauv qhov chaw ntawm lub vuam hlau nyeem tas feem hluav taws xob kuj. tshwj xeeb thermite cartridge yog siv rau feem ntau welding. Nyob rau hauv kev, nws yog ua siv thermite vuam hlau ua los ntawm txhuas thiab stalealyuminiya. Tseem muaj tshwj xeeb cov mos txwv siv rau cov tooj liab xov - lawv yog ua los ntawm cov hlau pwm.

Kev Nyab Xeeb nyob rau hauv vuam

Dua li ntawm qhov simplicity ntawm qhov kev siv ntawm lub vuam txoj kev yog vim hais tias ntawm cov kev tshuaj thaj chaw ntawm thermite mixtures yog txiav txim los ntawm heev nruj raws li kev ruaj ntseg cov kev cai. Firstly, tshwj xeeb uas yuav tsum tau rau lub koom haum ntawm lub cia ntawm nws yog xim hlau hmoov. Nws yog tsim nyog los muab rau cia nyob rau hauv qhuav thiab rhuab chav. Ntxiv mus, thermite vuam tsis pub siv ntawm ntub hmoov ncaj qha thaum lub sij hawm tiv cav tseb. Ob, tshwj xeeb uas yuav tsum tau thiab mus rau lub tej yam kev mob ntawm welding. Lub lag luam yuav tsum tau tsuas yog nyob rau ib tug kub saum toj no 10 ° C. Cov kev sib txuas yuav tsum tau yav tas los ntxuav thiab degreased.

Pros thiab cons ntawm thermite vuam

Cov kev pab cuam muaj xws li cov nyob rau ntawm cov ntaub ntawv, cov simplicity ntawm feem ntau ntawm cov neeg ua haujlwm thiab sab zog noj thaum lub sij hawm tua ntawm tej hauj lwm. Nyob rau hauv lwm yam lus, qhov no embodiment yog haum rau loj-scale vuam loj heev Siv thiab khiav hauj lwm rau me me tsev neeg. Raws li rau lub drawbacks, lub thermite vuam muab ib tug ntau ntawm teeb meem nrog rau cov kev seamless connectivity. Qhov tseeb hais tias cov khoom ncaj nraim thaum lub sij hawm tus tswv lag luam yuav tsis qoos saib xyuas qhov zoo ntawm cov kis tsim thiab cov tebchaw. Raws li ib tug tshwm sim, cia siab tias ib tug swm thiab huv si nws qhov chaw ntawm lug tsis muaj teeb meem loj deformation nyob rau hauv feem ntau yog tsis tsim nyog. Tab sis nyob rau hauv cov nqe lus ntawm lub dag lub zog thiab durability ntawm thermite tebchaw no yog raws li ib tug ntawm qhov zoo tshaj plaws.

Manufacturers ntawm Vuam khoom feem ntau txhim kho cov khoom siv rau tej, muab kev kawm ntawv siab instrument yog thermal los. Qhov no mus kom ze rau txoj kev loj hlob ntawm pab kiag li lawm yog tsis txhaum, tab sis lub lag luam ntawm cov khoom nrog nce hwj chim lawm yuav tsum tau loj kev nqis peev uas nyob rau hauv lub zog mov. Xyaum qhia tau hais tias thermite nyob rau hauv lub tsev, kev siv cov hlau hmoov mixtures raws li txhuas thiab magnesium nyob rau hauv lub tej kev quab yuam ua cov nyhuv tib yam li lwm txoj kev. Ib qho ntxiv uas yog hais tias lub ntsiab lus ntawm cov mixtures yog tseem yuav tsum tau ib tug ntau ntawm hassle thiab tus nqi. Tab sis cov no inconveniences them rau versatility technology. Cov muaj nyob rau hauv lub sector ntau yam ntawm cov hlau hmoov txhuas rau tungsten yuav tsim ib tug ntau yam ntawm mixtures haum rau lub tebchaw ntawm railway sleepers thiab mus ua hauj lwm nrog zoo nyob ntawm tej.
