Atmosphere box furnace sealing technology

1.1 Infrared instrument and oxygen probe can be used as sensors for multiple control to control the carbon potential of the atmosphere and the depth of the carburized layer.

Technical thinking

1. The airtightness and atmosphere uniformity of the atmosphere box furnace. A high-level, high-quality multi-purpose furnace should have:

(1) Good sealing performance:

(2) The atmosphere is stable and the composition fluctuation is small;

(3) Furnace temperature control, with good furnace temperature uniformity;

(4) The monitoring system reflects timely and accurately.

Whether it is carburizing quenching or bright quenching. The airtightness of the multi-purpose furnace and the uniformity of the atmosphere are both very important properties. Only a uniform and good atmosphere can ensure the uniformity of the surface of the workpiece and the consistency of the composition.
