The furnace adopts electric heating method, mainly for small batch or slender shaft workpiece without oxidation or bright heat treatment. Also applicable to all kinds of carbon steel tape, wire, wire; Metal parts are not oxidized or bright annealed.

Structure:

In the form of furnace structure, the furnace and the furnace cover are sealed with water-cooled rubber to ensure air tightness and have the function of vacuuming. In order to heat the workpiece evenly and increase the rate of rising and cooling, the upper end of the furnace cover is equipped with a heat flow fan and a diversion device to implement a strong convection circulation of the protective atmosphere in the furnace. A cooling air pipe is arranged in the bottom of the furnace or in the furnace bladder, and an exhaust pipe plug is arranged at the upper end. During cooling, a 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 heat treatment process, the material is always placed under the protection of high-purity nitrogen or hydrogen, so that the surface of the treated material is bright and non-oxidized.

The furnace is generally composed of the following parts: heating furnace body, stainless steel corrugated furnace bladder, hot air flow machine, vacuum pump, protective gas pipe valve, electric control system, cold air cooling, etc. The furnace protection pressure monitoring, flow adjustable, overpressure alarm and automatic pressure reducing function. The intelligent temperature transition control instrument is used to automatically control the temperature accurately according to the process requirements, and the whole heat treatment temperature process is automatically controlled. The whole process of temperature change is recorded and stored by U disk, which can be displayed directly on the computer and printed out.

Scope of application: carbon steel belt, wire; Copper wire, coil tube; Metal parts are not oxidized or bright annealed.

Well type bright annealing furnace, well type furnace RS Well type bright annealing furnace, well type furnace

I. Main technical parameters:

1, effective loading diameter: Φ800-2000mm

2, effective loading depth: 61500-3500mm

3, common working temperature: ≤700℃

4, heating power: 960-450KW

5, fan power: 4-37KW

6, protective gas consumption: 3-12Nm3/h

Ii. Remarks:

1, if no protective gas less oxidation heat treatment, no furnace structure, with independent partition temperature control, the working temperature can reach 1100℃.

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