Sebōpi sa ho futhumatsa maqhubu a mahareng litlhoko tsa tekheniki

1. Thyristor intermediate frequency inverter :

1.1 Ka ts’ebetso e felletseng ea sebopi se batang, qala sekhahla sa katleho: 100%; lintho tse chesang 100%. Sebōpi se phatlohang se qala ho futhumatsa thepa ea boraro ho fihlela mocheso oa ts’ebetso. ‘Me e ka forged ho qetela lintho tse bonahalang.

1.2 Motlakase o na le likarolo tsa 500 kw , ‘me boima bo feteletseng bo lumelloa ho ba 20% ka nako e khutšoanyane.

1.3 e lekantsoe matla a tlhahiso ea 500 kw a mathang matla a matla ka holimo ho 0.9.

1.4 Likarolo tse ka sehloohong tse kang li-thyristors ka har’a khabinete ea inverter ea IF le likarolo tse kholo tsa mohala kaofela ka ho khetheha li romelloa ho tsoa ho lisebelisoa tse tsoetseng pele tsa kantle kapa tsa lehae tse tsebahalang. Likarolo tsohle tsa moralo li hloka ho nkeloa sebaka ke boemo bo le bong ka lebaka la mathata a ho reka, ho netefatsa ts’ebetso e tsitsitseng le e tšepahalang ea lisebelisoa.

1.5 heater ea maqhubu a mahareng e na le ts’ebetso ea ho boloka mocheso (ts’ebetso e tlase ea maqhubu a phepelo ea matla a mahareng).

1.6 Ka mor’a ho futhumatsa, likheo tse sa tšoaneng li fihla mocheso oa mokhoa oa lisebelisoa tse fapaneng (1150 ° C), ‘me thepa ha e khomarele.

1.7 Sebopeho sa potoloho: inverter e tšoanang.

1.8 Tabeng ea ho feto-fetoha ha matla a marang-rang a 15%, ho fetoha ha motlakase oa IF output ha ho fete ± 1%.

1.9 brass dual reactor configuration, e hokahaneng le karolo e ka hare ea koporo e kholo ka ho lekaneng ho fokotsa feberu.

2. Induction futhumatsang:

2.1 Ho lumellana ha mocheso: Phapang ea mocheso oa holim’a pelo ea billet e fokotsehile ho ea bonyane ha e lokolloa.

2.2 Sensor e entsoe ka knotting ea boleng bo holimo, ‘me bophelo bo tloaelehileng ba coil ea sensor bo feta lilemo tse 3. Sensor linening e na le bophelo bo tloaelehileng ba tšebeletso ea nako e fetang selemo.

2.3 Terene ea tataiso e ka hare ea sensor e na le lisebelisoa tse sa senyeheng.

2.4 ka ho sebelisa moralo o tšoanang oa inductor, sekheo se ntse se eketseha butle-butle ho tloha pheletsong ea phepelo ho ea mocheso oa mocheso ho netefatsa hore sekheo ha se hlahise mapetso a manyane ts’ebetsong ea ho futhumatsa, ho chesoa ha mocheso o feteletseng le liphoso tse ling.

2.5 Coil ea inductor, bareng ea bese le likhoele tse hokahanyang li na le sebaka se seholo se arohaneng ho fokotsa mocheso.

2.6 Khokahano ea ka hare ea coil ea inductor e ka tšeptjoa, inductor e etsoa ka thata ho ea ka litlhoko tsa ts’ebetso, ‘me tlhahlobo e phahameng ea khatello e phahameng e etsoa pele ho kopano.

3. Mokhoa oa ho laola mocheso

3.1 Thermometer:

3.1.1 American Raytheon infrared thermometer e ka sebelisoa bakeng sa ho ts’oara le ho seta bocha ka boiketsetso. Boemong ba 1150 ° C, phoso ea tekanyo ea mocheso ha e fete ± 0.3%, ‘me ho nepahala ho pheta-pheta ha ho fete ± 0.1%.

3.1.2 Sesebelisoa sa ho lekanya mocheso ha se angoe ke bokaholimo ba oxide scale, lerōle, mosi le mouoane oa metsi.

3.1.3 Beha thermometer boema-kepeng ba ho lahla ho etsa bonnete ba hore matla a koalehile taolong;

3.2 Sesebelisoa sa ho laola: Mokhoa oa ho laola mocheso o na le mosebetsi oa ho fetola “PID” le taolo e koetsoeng ea mocheso oa sebōpi.

Molao-motheo oa taolo ea sistimi:

Taolo ea taolo ea motlakase nakong ea ho futhumatsa:

Nakong ea ho futhumatsa workpiece, phetoho ea matla e itšetlehile haholo ka lintlha tse peli.

Mocheso o laoloa ka loop e koetsoeng ho ea ka mocheso o behiloeng oa ho tlanya.

Ho ea ka tlhokahalo ea “beat beat” ea workpiece, tlhokahalo ea lebelo e finyelloa ke phetoho e koetsoeng ea loop ea matla.

4. Sistimi ea taolo ea motlakase:

4.1 Sehlopha se feletseng sa lisebelisoa se ka laoloa ka pel’a khabinete ea taolo kapa sebakeng sa ts’ebetso.

4.2 e khona ho sebetsa ka mokhoa o itekanetseng, oa semi-automatic, le mokhoa oa ho fetola ka letsoho.

4.3 Karolo ea ho laola Eketsa PLC ho segokanyimmediamentsi sa motho, beha li-parameter ka nako ea sebele, matla a pontšo, motlakase, hona joale, mocheso le likarolo tse ling, tse utloahalang le tse ka tšeptjoang.

5. Mehato ea polokeho:

5.1 Likarolo tsa khokahano ea lisebelisoa tsa motlakase li na le litemoso tse hlokahalang (matšoao a lehalima, litemoso, likarolo, joalo-joalo), tšireletso le tšireletso ho sireletsa tlhokomelo le polokeho ea opareitara.

5.2 Ts’ebetso e hokahaneng le ts’ireletso ea sehlopha sohle; Stop stop, over voltage, over current, phase loss, inverter failure, voltage cutoff, current cutoff, over the temperature of parts and under pressure and cooling of cooling system, mocheso o phahameng oa metsi (metsi ka ‘ngoe a khutla) Makala ohle a na le lisebelisoa tsa ho lemoha mocheso. ), le ts’ebetso e latelang (metsotso e ka tlase ho metsotso ea 15 ea ho fokotsa matla a phoso, ho feta metsotso e 15 ea ho koala phoso) le ho kopanya tse ling, alamo ea phoso, ho hlahlojoa ha phoso, joalo-joalo, ts’ebetso e feletseng, e ka tšeptjoang. Ho tiisetsoa hore lisebelisoa li ke ke tsa senyeha, ‘me ho hlōleha ha lintho tse bonahalang ka har’a heater ea induction le polokeho ea botho ho tla etsahala.

5.3 Sehlopha sohle sa lisebelisoa sea tšepahala ebile se na le nako e loketseng, e ka qobang ka katleho kotsi e bakoang ke tšebeliso e mpe ea thepa le ‘mele oa motho.

5.4 Ho hlahisa le ho kenya li etsoa ho latela Melao ea Tlhahlobo ea Tšireletso ea Indasteri ea Mechini ea Lekala la Indasteri ea Mechini.

5.5 E entsoe ho latela maemo a naha a ho futhumatsa sebōpi ‘me e kopana le litekanyetso tsa naha tsa ts’ireletso ea tikoloho le polokeho.
