The industrial pit furnaces are the ideal compromise between capacity/space and consumptions used for annealing, tempering, etc. With electric or gas versions, with super heating elements or high output pre-mixed burners, the consumption is further reduced.

 

The pit annealing furnaces are high-tech furnaces and widely used in the following processes: quenching and tempering, cementing, carbonitriding, soft nitriding, tempering under controlled atmosphere and simple heating. The charge resides inside a steel retort suitable for the operating temperature of the furnace, and the atmosphere is mixed by a special impeller on the lid.

 

The automatic opening and closing of the lid, allows the operator to concentrate on the loading and unloading of the bunch, greatly increasing the efficiency of operations. They are usually coupled with other treatment machines, such as washing machines, automatic storage and planning systems of production.

 

Pit annealing furnaces is widely applied in the annealing heat treatment process.

 

Structures: It consists of furnace shell, furnace lining, heating element, furnace cover, furnace door lifting device, intelligent electronic control system and son on.

 

2. Features of industrial pit furnaces.

1). If it is damaged by mechanical collision, it only needs local modification, repairing, replacement, and can be put into application after repaired without heating the empty furnace.

2). The refractory fiber is ceramic fiber block, with good heat preservation effect, fast temperature rising, it can save energy by 20% - 30% compared with brick lining.

3). The service life of pit furnaces is long

4). Adopt circulation fan within the furnace to stir the air in the furnace, to strengthen the internal gas flow, effectively increase the furnace temperature uniformity.

5). Seismic resistance performance is good.

6).Good temperature controllability, temperature control precision can be up to ±10

7). Furnace internal temperature partition piecewise control can be realized.

8). Good corrosion resistance, especially effective for sulfur-containing atmosphere and those that is polluted by sulfur-containing substance.

9). The furnace door lifting adopts hydraulic hoist, electric hoist, to control the opening and closing, with better gas tightness, and now the furnace can be made into round and polygonal, oblong, and other forms according to the requirements of different customers, furnace can load at the same time one or more different containers or artifacts.

 

Pit annealing furnaces is mainly used in annealing treatment for circular castings, all kinds of slender rods, steel wires, automobile spare parts, motorcycle spare parts, standard parts, and so on. Such furnace can also be made into deep industrial pit furnaces according to the actual requests.
