Main Features of Mesh Belt Furnace Line
1 General Introduction
1.1 The mesh belt furnace heat treatment line combines the advanced technologies from
Taiwan. Its key parts
are imported from overseas.
1.2 The mesh belt furnace production line is comprised of magnetic
belt charging machine, pre-cleaning machine,
support roller quenching furnace, quenching tank, oil removing
stand, post-cleaning machine, support-roller mesh belt tempering
furnace, and electrical control system.
2.Features:
2.1 To meet the production needs of fastening parts, the mesh belt furnace employs Taiwan technology,
and improves its energy-saving effect in the area of refractory
lining.
2.2 The production line employs low-voltage heating through the
transformer to prolong the service life of the heating tubes.
2.3 The mesh belt is supported by the support rollers with
synchronized movement so that the mesh belt bears a minimum
tension.
2.4 The rollers are supported by special high-pressure sealed
bearing.
2.5 The mesh belt is designed with abnormal transportation alarm
device to assure the stable movement of the mesh belt.
2.6 The drip-in atmosphere is gasified by a gasifier and then sent
into the furnace. The atmosphere is monitored and controlled
continuously by an oxygen probe.
2.7 The hot mesh belt returns back to the entrance of the furnace
and preheats the cold parts, which saves energy greatly.
