Molamu oa tšepe o tsoelang pele ho futhumatsa sebopi

Steel rod continuous ente e futhumatsang mollo

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.

Setšoantšo sa 12-51 ke sete sa tšepe ea molamu o bohareng o tsoelang pele ho futhumatsa sebopi. Molamu oa tšepe o behiloe sethaleng se thothomelang sa rack ea ho fepa, ‘me e huleloa lebaleng la ho fepa ka mochine oa ho hula o ikemetseng, o tsamaisoang ke tsamaiso ea lebelo le sa tsitsang la DC.

Sebōpi sena se sa khaotseng sa ho futhumatsa se sebelisetsoa ho futhumatsa mekoallo ea tšepe e bolelele ba Φ55 – Φ 100 mm le bolelele ba 6m . Mocheso oa ho futhumatsa ke t = 1200 ℃ ± 25Y, ke hore, phapang ea mocheso pakeng tsa bokaholimo le mokokotlo oa bar ke 50 ℃, ‘me tlhahiso ke 3600kg / h. Inverter ea thyristor e tsamaisoa, hangata ke 1100Hz, matla ke 1 320kW, ‘me litekanyo tse amehang tsa inductor li bontšoa ho Lethathamo la 12-10.
