tempering;
1.3 productivity: quenching: 150-250kg/h;
Main Features of Mesh Belt Furnace
1. General Introduction
1.1 The mesh belt furnace combines the advanced technologies from
Taiwan. Its key parts are imported from overseas.
1.2 The production line is comprised of 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 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.
