As described above, the melt-discharged sand produced through the heating device 4 is quenched and solidified while passing through the cooling zone of the cooling device 5.

At this time, a short heating device 4 may be installed at a distance from the lower part of the nozzle 3 to the start position of the cooling zone of the cooling device 5, that is, the length L of the hood.

The length (L) of the hood is a delay cooling zone or heating zone, the length (L) of the hood has a 50 to 250mm, the air contact surface temperature is 250 to 400 ℃.

Here, according to the method of blowing the cooling air in the cooling zone of the cooling device (5), it is preferable that Open Quenching, Circular Closed Quenching, and Radial Outflow Quenching are applied. However, it is not limited thereto.

The discharged yarn solidified while passing through the cooling zone of the cooling device 5 is first oiled through the spinning oil feeder 12 provided in the lower part of the cooling device 5 to become an undrawn yarn.

Example 1

An oil was oiled to the stretched yarn during the stretching process through each spinning oil feeder provided sequentially between the front and rear ends of each gourd roller.

At this time, a water dispersion emulsion oil was used as an oil agent, and the yarn was manufactured by making the relative value of the usage-amount of a water dispersion emulsion oil into 90.

Example 2

An oil was oiled to the stretched yarn during the stretching process through each spinning oil feeder provided sequentially between the front and rear ends of each gourd roller.
