What Are the Common and Commonly Used Types of Shaft Furnaces?

1. Pit-type resistance furnace.

The pit-type resistance furnace is a cyclically operated furnace suitable for the heat treatment of bars and long shaft parts. It is mainly used for quenching, tempering, annealing and other heat treatment of steel parts in an oxidizing atmosphere.

Kejing's high temperature laboratory furnace achieves stable heating through precise temperature control, which prevents steel parts from bending due to gravity and ensures uniform heating. Our high temperature lab furnace is widely used in the manufacturing and processing of long-sized steel parts such as auto parts, machine tool spindles, and large bolts—specifically in quenching (to improve part hardness), tempering (to adjust part toughness), and annealing (to eliminate internal stress and facilitate subsequent processing). Additionally, Kejing's high temperature laboratory furnace features a compact and lightweight design, with its core characteristics as follows:

·Adopt multi-stage intelligent temperature control design, which can refine the temperature control interval according to different experiments or small batch processing requirements, further optimizing furnace temperature stability and consistency;

·The furnace cover adopts a manual and convenient opening and closing design, and is equipped with a precise positioning structure, which saves labor and ensures a smooth opening and closing process of the furnace cover, and fits the use scenarios of small equipment;

·The furnace body and furnace cover are made of high-density energy-saving insulation materials, which effectively reduces heat loss at high temperatures of 1200 ° C, reduces energy consumption, and saves use costs;

·No harmful gas emissions are emitted during the operation process, and the small size design reduces the floor area, which meets the environmental protection and space requirements of laboratories and small production scenarios, and has excellent environmental benefits.

2. Deep well furnace.

Deep well furnaces are specially used for quenching, tempering and other heat treatment of long-axis workpieces. Adopt a split structure, and the length of the workpiece can reach 10 meters. The control system adopts intelligent instruments and PID adjustment, and has the characteristics of high temperature control accuracy. The applicable heat treatment temperature range is 650-1000℃, which can stably ensure the structural transformation requirements of large-size carbon steel parts during the tempering process.

3. Deep well resistance furnace.

Deep well resistance furnace is a vertical heat treatment equipment specially designed for long size workpieces. With its vertical furnace structure and precise temperature control capabilities, it can adapt to the heating and process treatment of long members such as shafts. It is mainly used for quenching, normalizing, annealing and other heat treatment of long workpieces such as shafts.

4. All-fiber deep well furnace. 

The all-fiber deep well furnace is a light and efficient well furnace lined with ceramic fiber modules. Its lining is composed of ceramic fiber modules and ceramic fiber blankets. Application: Full fiber deep well furnace is mainly used for shaft quenching and normalizing.

5. All-fiber well type resistance furnace. 

The lining is made of a new type of high-purity silk carpet and specially processed. The temperature control adopts PID intelligent fully automatic control in the upper and lower areas. It can be programmed according to the process of the workpiece. It can be followed by the insulation curve. The furnace cover can be lifted manually or electrically according to the weight. Suitabl for alloy rings, flanges and wires for high-temperature soaking, normalizing, tempering, annealing, quenching and other purposes.
