Common Furnace Types

Furnaces play a vital role in the heat treatment industry, and different types of furnaces are suitable for different heat treatment processes. Let’s take a look at the common stove types and their characteristics.

Quenching Furnace

Quenching furnaces are used to rapidly cool metallic materials to produce high hardness and strength. It usually uses gas or liquid media for cooling, such as water, oil or salt baths. Quenching furnaces are usually divided into salt bath quenching furnaces, gas quenching furnaces and oil quenching furnaces.

Annealing Furnace

Annealing furnaces are used to heat metal materials to a higher temperature and then slowly cool them to reduce residual stress, improve processing performance and increase the toughness of the material. Annealing furnaces are usually divided into gas annealing furnaces, box-type resistance heating annealing furnaces and other types.

Heat Treatment Furnace

Heat treatment furnaces are used to perform a series of heating, insulation and cooling treatments on metal materials to achieve specific organizational and performance requirements. It usually has a sophisticated temperature control system and multi-functional process control functions.

Vacuum Furnace

Vacuum furnaces are used to heat treat metal materials in an oxygen-free or low-oxygen environment to avoid oxidation and surface contamination while achieving precise process control. It is usually used in the processing of high temperature alloys, powder metallurgy materials, etc.

Atmosphere Furnace

Atmosphere furnaces are used for heat treatment under specific atmosphere conditions, such as hydrogen, nitrogen or oxygen. It can achieve special heat treatment effects such as surface modification and surface hardening.

The above are some common furnace types, which play different roles in the heat treatment industry and meet the needs of various materials and process requirements.
