Product Description

Equipment features and description of working process:

It is mainly designed for heating of copper, copper alloy in controllable atmosphere before rolling. This production line adopts the most advanced and reliable atmosphere control technique. The whole working procedure can be automatically controlled; It saves investigation cost, with high thermal efficiency, reliable and safety operation.

Installation level and Main Characteristics:

To save energy, reduce heat loss, it adopts one end loading and the other end unloading method, furnace door will need not to be frequently opened during production.

The proper and reliable hydraulic system ensures slab can be evenly and smoothly transferred in side of furnace chamber, no sliding and no scratch; The advanced positioning devices and aligning devices can make sure that slab can exactly positioned and delivered to rolling machine.

High quality imported combustion device and perfect control system ensure temperature can be automatically controlled; The double-cross limit controller ensures air-gas ratio is automatically regulated, and atmosphere inside of furnace chamber is adjusted.

Each heating zone can be individually controlled with help of analyzer and industrial PC. Inner atmosphere can be regulated as micro-reducing atmosphere, neutral atmosphere, and micro-oxidizing atmosphere.

To meet requirement of small batch of workpieces to be suitable to heated in the furnace, working process can be modified or re-set at any time.

The "soften loading" function ensures surface of slab remain in good condition.

To improve surface quality of slab flow rate inside of furnace chamber can be regulated. Burner can be controlled automatically or remote manually controlled.

The "stepping" function ensures slab can be uniformly heated.

Proper history records function.

The working process parameter and temperature curves are recorded and stored in the industrial PC.

Slab numbers will be automatically calculated in the control system.

Alarm history will be stored for operator analyzing and management.
