Bobina posizionata molto dopo il miglioramento della direzione del flusso d'aria calda e il modo di cambiare, prima che il miglioramento del flusso di aria calda sarà più lento, questo perché la spira della superficie superiore e inferiore è più grande, gli effetti di blocco dell'aria calda saranno più evidenti, e perché la superficie della bobina e la direzione sono perpendicolari tra loro, so hot blast theory on each plate stay longer, so the temperature of the hot air will decline, hot air in contact with the plate, the temperature will be lower than the previous temperature, thus more let the temperature differences between different coil increasing.In addition, due to the surface of the hot air leaving the coil, il 90 - degree shift will happen, this shift is largely theoretical, in most cases the wind of change is not 90 gradi, so the wind will happen after a coil, questo è, when the vertical blowing hot air after a first coil of the wind, not as a vertical direction will happen some deviation, and with the upward mobility, hot wind deviation will be more and more big, so at the top of the furnace, the wind will be very confusion, may appear more than hot breeze blowing the same coil at the same time,And some coil and no hot wind to heat the situation.
il numero e la morfologia di queste fasi dipendono dalla temperatura di pre-invecchiamento, the improved coil placement method can effectively increase the number of coils placed in the furnace, which can also greatly reduce the cost of coil heating.
summary
Through the above analysis, we can see clear that improvements in the annealing furnace coil placed way, confezionamento del prodotto finito, effectively alleviate the same coil heating temperature nonuniformity, and also can effectively reduce the temperature difference between the different coil, the last is the laying methods can increase the number of coil is placed inside the furnace, reduce the cost of heating coil.
