Lift type bell jar furnace

The lifting bell jar furnace is an intermittent production or experimental kiln that achieves efficient loading and precise process control through the lifting of the furnace body, suitable for material processing in multiple fields. The following is a detailed explanation of its core characteristics, application areas, and advantages:

1. Core Features
Design of lifting furnace body:
The furnace body is vertically lifted and lowered by a hydraulic or electric screw system, with a large furnace opening and sufficient operating space, making it easy to load and unload large and irregular workpieces. For example, the dual cart cyclic feeding design can achieve continuous production and reduce downtime.
Efficient insulation and energy saving:
The furnace is made of alumina polycrystalline fiber or lightweight ceramic fiber material, which reduces weight by 2/3 and improves insulation performance. The double-layer furnace shell structure is equipped with an air-cooled circulation system to ensure that the outer wall temperature of the furnace body is ≤ 45 ℃, resulting in better energy-saving effect.
Precise temperature control and atmosphere control:
Equipped with PID intelligent temperature control system, the temperature control accuracy is within ± 1 ℃, and it supports 30 programmable temperature curves. Vacuum can be evacuated to ≤ 10 ⁻ ³ Pa, or protective gases such as nitrogen, argon, hydrogen can be introduced to prevent material oxidation or achieve specific reactions.
Safety and operational convenience:
The furnace body is made of high-temperature resistant materials, with good insulation performance, and equipped with multiple protections such as overheating, breaking, overcurrent, and leakage. The 7-inch touch screen dynamically displays the heating curve, supports RS-485 serial port computer communication, and enables remote monitoring and data tracing.

2. Application Fields
