Ndodo yachitsulo yosalekeza yotenthetsera ng’anjo

Steel rod continuous magetsi oyatsira moto

In steel and machinery manufacturing plants, when the output is large, the continuous induction heating method for steel bars is now used more. After the steel rod is heated, it is subjected to hot shearing, and then die forging or stamping.

Chithunzi 12-51 ndi seti yachitsulo ndodo yapakatikati pafupipafupi mosalekeza kutenthetsa ng’anjo. Ndodo yachitsulo imayikidwa pa nsanja yogwedezeka ya choyikapo chakudya, ndipo imakokedwa kupita kumalo odyetserako chakudya kudzera mu makina okoka okha, omwe amayendetsedwa ndi kayendetsedwe ka kayendedwe ka DC motor. Wodzigudubuza wodyetsa amadyetsa bar ku inductor kuti atenthetsedwe. Kuchuluka kwa masensa kumatsimikiziridwa molingana ndi kukula kwa bar ndi zotsatira zake. Masensa awa amakonzedwa molunjika. Ng’anjo yotenthetsera yosalekeza imeneyi imagwiritsidwa ntchito kutenthetsa zitsulo zazitsulo zotalika Φ55 – Φ 100 mm ndi kutalika kwa 6m. Kutentha kwa kutentha ndi t = 1200 ℃ ± 25Y, ndiko kuti, kusiyana kwa kutentha pakati pa pamwamba ndi pakati pa bar ndi 50 ℃, ndipo zokolola ndi 3600kg / h. The thyristor inverter imayendetsedwa, mafupipafupi ndi 1100Hz, mphamvu ndi 1 320kW, ndipo magawo oyenerera a inductor akuwonetsedwa mu Table 12-10.

Ma inductors amagawidwa m’magulu atatu malinga ndi kukula kwa ndodo zachitsulo. Powotcha ndodo zachitsulo zamitundu yosiyanasiyana, ma inductors ofanana ayenera kusinthidwa. Mpaka 10 inductors akhoza kuikidwa pa induction ng’anjo yotentha. Kutalika kwa koyilo ya inductor ndi 550mm. Pambuyo pochiza chithandizo, koyiloyo imakutidwa ndi nsalu yotchinga kutentha yomwe imapangidwa ndi ubweya wa mchere komanso wosanjikiza wosatentha wopangidwa ndi zinthu zotsutsa. Pomaliza, bolodi la simenti la asbestosi limagwiritsidwa ntchito popanga bokosi, ndipo koyiloyo imakhazikika m’bokosi. . Kutalika kwa bokosi lililonse ndi 600mm, mtunda woyika pakati pa bokosi ndi bokosi ndi 200mm, ndipo chothandizira chodyetsa cholankhulidwa chimayikidwa pakati.

Mphamvu ya inductor ndi yakuti ma inductors awiriwa amagwirizanitsidwa mndandanda woyamba, ndiyeno amagwirizanitsidwa mofanana pa mzere wamagetsi, monga momwe tawonetsera pa Chithunzi 12-52.

Chithunzi 12-53 ndi mzere wopitilira muyeso wopangira kutentha wopangidwa ndi kampani yakunja yokhala ndi mphamvu ya 12MW, okwana 26 inductors, ndi kutalika kwa 157 m (47.86m) .
