Operational Parameters

Temperature Control and Uniformity

Temperature control and uniformity are critical parameters in the successful operation of a trolley type heat treatment gas furnace. The temperature must be precisely controlled to ensure that the workpieces are heated to the desired temperature without being overheated or underheated. The temperature uniformity must also be maintained to ensure that all workpieces are heated evenly.

To achieve these goals, the furnace must be equipped with a reliable temperature control system. This system should be capable of measuring and controlling the temperature within a narrow range. It should also be able to adjust the temperature quickly and accurately in response to changes in the process parameters.

Atmosphere Management

Atmosphere management is another important parameter in the operation of a trolley type heat treatment gas furnace. The atmosphere inside the furnace must be carefully controlled to prevent oxidation or other chemical reactions that could damage the workpieces.

To achieve this, the furnace must be equipped with an atmosphere control system that can maintain the desired gas composition and pressure within the furnace. The system should also be able to monitor the atmosphere and adjust it as necessary to maintain the desired conditions.
