Graphite mold vacuum heat treatment furnace is a furnace used to heat treat graphite molds in a vacuum environment. It consists of a furnace, a heating element, a vacuum system, and a control system.
The furnace is where the graphite mold is placed. It is usually made of high-temperature resistant materials such as graphite or ceramic. The heating element is used to heat the furnace to the desired temperature. They can be made of resistance wires, induction coils, or radiant heaters.
The vacuum system is used to remove air from the furnace chamber. This prevents the graphite mold from oxidizing during the heating process. A vacuum system usually consists of a vacuum pump and a vacuum tube.
The control system is used to control the temperature and vacuum level of the furnace. It usually consists of a temperature controller and a vacuum controller.
Graphite mold vacuum heat treatment furnaces are used in a variety of applications, including:
Annealing: The graphite mold is heated to a high temperature and then cooled slowly to make it softer and more ducid.
Quenching: Graphite molds are heated to high temperatures and then cooled quickly to make them harder and more wear-resistant.
Tempering: The quenched graphite mold is heated to a lower temperature to make it more ducid.
Graphite mold vacuum heat treatment furnace has the following advantages:
Prevents oxidation of graphite molds
Improve the hardness and wear resistance of graphite molds
Improve the toughness and strength of graphite molds
Improve the surface finish of graphite molds
The disadvantages of graphite mold vacuum heat treatment furnace include:
High cost of equipment
High operating costs
High maintenance requirements
