What safety protection knowledge about multi-purpose furnace heat treatment?

1. In order to prevent heat radiation, furnace walls should be filled with asbestos, diatomaceous earth, slag wool, expanded perlite and other insulation materials; furnace doors should be equipped with baffles and doors with circulating cooling water or air curtains.

2. The nozzles of gas and liquid fuel furnaces should be placed on the side walls of the furnace, and should not be placed on the back wall of the furnace opposite to the furnace door, so as not to burn personnel when the furnace door is opened, the flame of the heat treatment furnace should be sprayed out. Artificial ignition is not safe. Spark ignition devices should be used whenever possible.

3. The fuel tank of the oil stove is not allowed to be installed on the stove top. Exhaust devices and air valves should be provided at the branch of the piping system.

4. The furnace gas pipeline and flue must not cross. Safety valves should be installed to reduce the pressure in the pipeline in the event of an explosion.

5. The electric furnace must be well insulated.

6. The salt bath furnace will volatilize the harmful steam when it is heated. Therefore, it is necessary to install ventilation.

7. Various heat treatment multi-purpose furnaces should be equipped with automatic temperature control devices, which can not only meet the requirements of heat treatment processes, but also be conducive to safe production and improve working conditions.

There are many types of automatic temperature control systems, which can be selected according to the furnace type and process requirements.
