Product Details

150-250 Kg/H Support Roller Mesh Belt Furnace Automatic for Drywall Screws

 

Application of Mesh Belt Furnace 

1.1 product: self-tapping screw, steel wall screw.

1.2 process: carburizing, carbonitriding, bright quenching and 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.
