1.Buyer Requirement

1.1 product: fasteners, sleeves;

1.2 process: bright quenching, tempering;

1.3 productivity: quenching: 200-250kg/h;

3. Equipment General Introduction and Main Features

1 General Introduction

1.1 The heat treatment line combines the advanced technologies from

Taiwan. Its key parts are imported from overseas.

1.2 The 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.

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 partss, which saves energy greatly.
