Large deep pit type furnace and supporting water tank
Heating source: natural gas, resistance heating
Production capacity and design working temperature: non-standard customization
Basic structure of deep pit type furnace: mainly composed of furnace shell, furnace lining, heating elements, heat-resistant steel, furnace cover, furnace cover mechanical / hydraulic lifting mechanism, hot air circulation and cooling system.
Application of deep pit type furnace equipment: mainly used for long rod workpieces. For example, the normalizing, quenching, tempering and other heat treatment heating of workpieces such as barrel, turbine main shaft, generator rotor, marine diesel engine main shaft, roll, etc. can also be used for tempering and even temperature heat treatment of oversize carbon steel parts.
Detailed introduction of deep pit type furnace:
Main features of deep pit type furnace: large deep pit type furnace belongs to the intermittent heating furnace type. The furnace temperature changes with time according to the specified heating procedure. It has a vertical running furnace with a diameter of 0.5-4.5m and a maximum furnace depth of more than 30 meters. The junction of the well furnace is generally set on the top of the furnace, and the workpiece is vertically loaded into the furnace with a special sling for heating, so as to avoid bending deformation. In addition, the shaft furnace is generally equipped with a fast lifting bridge crane, which can quickly load the workpiece into the furnace or lift it out of the furnace, so that the temperature of the workpiece after heating can be minimized during quenching.
