Well type bright annealing furnace

The furnace adopts electric heating method, mainly for small batch or slender shaft workpiece without oxidation or bright heat treatment. It is also suitable for all kinds of carbon steel strip, wire, wire, metal parts, etc. without oxidation or bright annealing.

Well type bright annealing furnace structure:

The structure of the furnace tank is adopted, and the furnace tank and the furnace cover are sealed with water-cooled rubber to ensure air tightness and vacuum pumping function. In order to heat the workpiece evenly and improve the speed of temperature rise and fall, the upper end of the furnace cover is equipped with a heat flow fan and a guide device to carry out a strong convection cycle for the protective atmosphere in the furnace. Cooling air pipes are respectively arranged at the bottom or in the furnace tank, and exhaust pipe plugs are arranged at the upper end. During cooling, the frequency conversion pressure fan is used to blow cold air to cool down quickly, which effectively solves the problem of difficult cooling of the well furnace. In the process of heat treatment, the material is always under the protection of high purity nitrogen or hydrogen, so that the surface of the treated material is bright without oxidation.

The furnace is generally composed of the following parts: heating furnace body, stainless steel corrugated furnace, hot air flow machine, vacuum pump, protective gas pipe valve, electric control system, cold air cooling, etc. The furnace has the functions of air pressure monitoring, adjustable flow, overpressure alarm and automatic pressure relief. The intelligent temperature crossing control instrument is adopted, and the temperature is controlled accurately by PID in different sections according to the process requirements, and the temperature process of the whole heat treatment is controlled automatically. The whole process of temperature change is recorded and stored by U disk, which can be displayed and printed on the computer.

Scope of application: carbon steel strip, wire, copper wire, coil, metal parts, etc. without oxidation or bright annealing.

1、 Main technical parameters:

1. Effective loading diameter: Φ 800-2000mm

2. Effective loading depth: 61500-3500mm

3. Common working temperature: ≤ 700 ℃

4. Heating power: 960-450kw

5. Fan power: 4-37kw

6. Protection gas consumption: 3-12nm3 / h

2、 Note:

1. If there is no protective gas, less oxidation heat treatment and no furnace structure, the temperature can be controlled by independent zone, and the working temperature can reach 1100 ℃.

2. For example, using high purity nitrogen as protection gas, using heat-resistant steel furnace and strong circulation fan, the working temperature can reach 850 ℃.
