Mokhoa oa ho lokisa bakeng sa lekhalo la roll ea Multi Stand Reducing Rolling Mill ke ofe?

       TheMulti Stand Reducing Rolling Millke lisebelisoa tsa mantlha tsa ho qetela bakeng sa tlhahiso ea liphaephe tsa tšepe tse seamless. Lekhalo la moqolo le khetholla ka ho toba ho fokotseha ha boemo bo le bong, ho nepahala ha bophara ba ka ntle, ho lekana ha lerako le boleng ba holim'a li-tubes tse felileng. Litlhophiso tse fapaneng tsa sebopeho li amohela mekhoa e fapaneng ea ho lokisa lekhalo la roll, haholo-holo ho kenyelletsa tokiso ea eccentric sleeve synchronous, tokiso ea mochini oa motlakase, phetoho e ntle ea hydraulic le tokiso ea letsoho. Basebelisi ba ka beha liparamente sebakeng sa heno kapa ba le hole le khomphutha e kholo ea taolo. Mefuta e meng e tsoetseng pele e tšehetsa phetoho e ntle ea inthanete nakong ea ho thetheha ho tsitsitseng ho tsitsisa ho nepahala ha phaephe.

Main Roll Gap Adjustment Mekhoa

1. Eccentric sleeve synchronous phetoho 

       Ena ke sebopeho se atileng haholo bakeng sa tshilo e fokotsang 3-roll. Moqolo o mong le o mong o kenngoa ka har'a sleeve ea eccentric. Li-sleeve tse tharo tsa eccentric li hokahantsoe ke li-gear tsa sector bevel bakeng sa ho potoloha ha synchronous. Ho potoloha lesela la eccentric ho fetola boemo ba radial ba reng ea roll, 'me ka tsela e lumellanang ho bula kapa ho koala likheo tse tharo tsa roll ka nako e le' ngoe.

       Melemo: Setsi sa roll se lula se sa fetohe nakong ea phetoho, coaxiality e ntle; meqolo e meraro fetola synchronously, lekhalo junifomo; boima bo phahameng, bo tsitsitseng tlas'a moroalo o chesang. 

       Kopo: E sebelisoa bakeng sa phokotso e nepahetseng ea liphaephe tse se nang seamless, tse loketseng tšepe ea carbon, tšepe ea alloy le li-tubes tsa tšepe tse sa hloekang.

       Ts'ebetso: E tsamaisoa ke sistimi ea liboko kapa ea letsoho, liparamente li ka bolokoa ka har'a risepe ea rolling.

2. Sekoti sa motlakase / phetoho ea mechine ea motlakase

       Mochine oa screwdown oa motlakase o sebelisa motor, reducer le screw pair ho khanna motsamao oa roll chock ho fetola lekhalo la roll, le sebelisoang haholo ho li-roll tse peli.Multi Stand Reducing Rolling Mill.

       Melemo: Sebopeho se bonolo sa mochini, litšenyehelo tse tlase tsa tlhokomelo, tse tsitsitseng bakeng sa nako e telele e tsoelang pele e chesang. Boleng ba tokiso bo ka khutlisetsoa ho sistimi ea PLC, ho ts'ehetsa ho seta ho hole ho tloha ho HMI.

       Moeli: Lebelo la litokiso le batla le tsamaea butle, haholo-holo le sebelisoa bakeng sa ho seta pele ho marang-rang le ho lokisoa ha maemo; ha e loketse tokiso e ntle ea inthanete e potlakileng haholo.

3. Phetoho e ntle ea Hydraulic / hydraulic AGC e thusang phetoho

       Boemo bo phahameng ba kajenoMulti Stand Reducing Rolling Millli na le sistimi ea hydraulic cylinder servo-tuning system. Ha e kopantsoe le laser gauge kapa sesebelisoa sa ho lekanya bophara ba kantle, e theha taolo e ikemetseng ea loop. Li-cylinder tsa Hydraulic li etsa tokiso e nyane ea nako ea nnete ho sekheo sa roll nakong ea ts'ebetso.

       Melemo: Karabelo e potlakileng, ho nepahala ho phahameng, ho lefella leloala la selemo ka lebaka la ho feto-fetoha ha matla. Ka katleho e ntlafatsa phala e phethiloeng ea OD le botenya ba lebota bo tsitsitseng.

       Moeli: Litlhoko tse phahameng tsa matsete le tlhokomelo, li hloka tlhokomelo ea oli ea hydraulic le tlhahlobo ea khafetsa ea li-valve tsa servo.

4. Phetoho ea letsoho (lebili la letsoho / gear ea seboko ka letsoho)

       Phetoho ea letsoho e sebelisoa bakeng sa liloala tse nyane tsa batch kapa ho lekanya hantle ka mor'a phetoho ea moqolo. Basebelisi ba bilikisa lebili la letsoho le lisebelisoa tsa seboko ho khanna sekoti sa eccentric kapa mochini oa screw ho fetola sekheo sa roll.

       Melemo: Ha ho na matla a hlokahalang, a loketseng tlhahlobo ea static, calibration le ho netefatsa lekhalo la roll nakong ea tlhokomelo ea lisebelisoa.

       Moeli: Tšebeliso e tlaase, e ke ke ea sebelisoa nakong ea ho roala; feela bakeng sa litlhophiso le ho hlahloba ntle le inthanete.

Mekhoa ea Ts'ebetso: Litokiso tsa lehae le litokiso tse hole tsa inthanete

       1. Tokiso ea sebakeng sa on-rack: Basebelisi ba lekanya setulo se seng le se seng setšeng ka mor'a phetoho ea roll, ba sebelisa seea-le-moea kapa teko ea indentation ho netefatsa boleng ba 'nete ba lekhalo, ho lefella leloala le hlabang.

       2. Remote console e lokisoa: Kamora ho boloka li-recipes, basebelisi ba kenya li-parameter tsa target roll gap ho HMI ka phaposing ea taolo e bohareng. Sebaka se seng le se seng se etsa liphetoho tse seng li setiloe ka mokhoa o lumellanang. Bakeng sa likarolo tse tsoetseng pele, tokiso e nyane ea inthanete e ka etsoa ntle le ho emisa leloala tlas'a boemo bo tsitsitseng.

Lintlha tsa Bohlokoa tsa Phetoho ea Lekhalo la Roll

       1. Roll gap setting e lokela ho ela hloko leloala spring bounce. Hot rolling tla hlahisa rekere deformation ea leloala matlo, e leng lokela ho busetswa ka palo palo ea paramethara.

       2. Ha u fetola lipehelo tsa liphaephe, seta sekheo sa roll bakeng sa sethala se seng le se seng, bapisa tsitsipano ea lipakeng le lebelo la lebelo hammoho. Lekhalo le sa nepahalang la moqolo le motsoako oa tsitsipano li baka poligone e ka hare habonolo, ho kheloha botenya ba lebota kapa mengoallo.

       3. Bakeng sa leloala la ho fokotsa li-multi-stand, lekhalo la moqolo oa setopo ka seng se tlameha ho hokahanngoa, eseng ho lokisoa ka thoko. Kabo ea phokotso ea mohala o felletseng oa tlhahiso ke sete e felletseng ea risepe ea theknoloji.

       4. Ka mor'a ho roala ha roll, hlahloba lekhalo hape 'me u lokise lekhalo khafetsa ho boloka ho mamellana ha pipe e se nang seamless.

       Mokhoa oa ho lokisa lekhalo le ka sehloohong bakeng saMulti Stand Reducing Rolling Millke eccentric sleeve synchronous adjustment, e tsamaellanang le drive ea motlakase bakeng sa ho seta esale pele. Mehala e phahameng ea tlhahiso e nepahetseng e eketsa hydraulic servo-tuning bakeng sa tokiso ea inthaneteng. Meetso ea lirolo tse peli hangata e sebelisa li-screw tsa motlakase, ha ho lokisoa ha mabili a letsoho ka letsoho ho sebetsa bakeng sa ho lekanya ho tsitsitseng. Ho khetha sebopeho se nepahetseng sa ho lokisa ho itšetlehile ka thepa ea phala, tlhokahalo ea mamello ea boholo le bokhoni ba tlhahiso. Taolo e nepahetseng ea lekhalo le thusa ho tsitsisa bophara ba tube ea kantle, ho fokotsa sekhahla sa ho hana le tahlehelo e tlase ea hlooho le mohatla.
