A high temperature furnace (or high temp. furnace) is useful for melting as well as heat treating different materials. You can use a high temperature furnace for melting a number of metals and alloys including both ferrous and non-ferrous alloys. You can also use high temperature furnaces for different heat treating applications including annealing, hardening, carbo-nitriding and calcining.

Suppliers of high temperature furnaces can provide high temperature furnaces in different types and configurations. A high temperature furnace could be a box furnace, a muffle furnace, a belt furnace or a pit furnace. You can also buy a continuous or batch type high temperature furnace depending on your production requirement. You can also buy high temperature forced air furnaces if your application requires controlled air (or gas) flow.

Some important parameters you must consider before you buy a high temperature furnace are:

1. Type of heat treatment process
2. Material, dimensions and weight of the products
3. Power consumption of the high temperature furnace
4. Gas environment within the high temperature furnace
5. Requirement of over temperature protection device

The best contacts and resources to help you get it done

Buy a furnace from reputable manufacturers of high temperature furnaces

Once you have enough information on high temperature furnaces and your application needs, buy a high temperature furnace that suits your heat treating requirements.

I recommend: Sentry Company is a furnace manufacturer that supplies high temperature electric furnaces with uniform heat distribution patterns. CM Furnaces supplies batch and continuous type high temp furnaces. You can also buy high temperature forced air furnaces at Thermal Product Solutions, another reputable manufacturer of furnaces.

Buy high temperature furnaces from distributors or retailers

You can compare different high temperature furnaces based on their features and prices at distributors or retailers' websites. You can also buy a used high temperature furnace to get a cost-effective solution for your requirements.

I recommend: S & S Furnace Sales, a used furnace distributor, can supply various furnaces including high temperature furnaces. Cole-Parmer is another distributor that sells high temperature furnaces. Machinery & Equipment Company provides used furnaces from reputable manufacturers such as Harper, Cress and Lindberg.

Buy customized high temperature furnaces

Even though the high temperature furnace itself is a specialty furnace, you might need a high temperature furnace that has non-standard characteristics. You can ask the suppliers of high temperature furnaces to manufacture a furnace to suit your requirements.

I recommend: If you need an ultra-high temperature heat furnace, check out the products offered by L&L Special Furnace, a custom manufacturer of furnaces. You can buy a high temperature infrared furnace at Despatch, another supplier of heat treating equipment. Thermal Technology can design and manufacture high temperature furnaces as per customers’ requirements.

Tips & Tactics
