Bottom lifting furnace is an industrial equipment used for high-temperature treatment processes, commonly applied in fields such as metallurgy, glass manufacturing, and ceramic production. Its primary feature is the ability to adjust the height of the furnace bottom through lifting devices, thereby controlling the contact time and temperature of materials within the furnace chamber. Typically operating within a temperature range of 400-1700°C, this equipment's basic structure comprises the furnace body, heating apparatus, and bottom lifting mechanism. Heating is achieved through resistance heating, with specific material selection depending on process requirements and material properties. The design of the bottom lifting furnace enhances process flexibility and efficiency by allowing adjustments to the furnace volume and material processing time as needed.

The main components of the lifting furnace include:

1. Furnace Body (Chamber): The furnace body is the main part of the bottom lifting furnace, used to accommodate materials and provide heating space. It is typically constructed from ceramic fiber materials (plates, blankets, etc.) to withstand high temperatures and chemical corrosion. In addition to ceramic fiber materials, wear-resistant materials such as hollow sphere bricks are also chosen for the bottom platform to ensure long-term quality stability.
2. Heating Elements: Heating elements provide heat energy inside the furnace chamber to heat the material to the desired target temperature, ranging from around 1200°C to 1700°C. They are typically made of resistance wires (belts), silicon carbide rods, or silicon molybdenum rods.
3. Bottom Lifting Mechanism: The bottom lifting mechanism is one of the key components of the bottom lifting furnace, used to adjust the height of the furnace bottom. Through the lifting mechanism, the distance between the material and the heat source can be controlled, thus adjusting the heating time and temperature of the material. The lifting mechanism typically consists of hydraulic systems and screw rods. The bottom platform adopts a ladder-like structure, which fits with the furnace chamber, saving energy and insulation while reducing heat loss and improving sealing effectiveness.
4. Control System: The control system monitors and regulates the operation of the bottom lifting furnace, including parameters such as temperature, pressure, and lifting speed. Temperature control is usually achieved by temperature controllers, and the lifting movement is controlled by variable frequency drives. Large-scale lifting furnaces are equipped with touchscreen controls to improve production and control efficiency.

Optional Features:

1. Customizable Control Modes: Control modes can be customized from traditional domestic PID control to imported instruments or PLC control, providing various options to meet different customer preferences.

2. Platform Entry and Exit: Platform entry and exit can be customized for automatic movement, with a maximum of two platforms to facilitate loading and unloading while firing on one side.

3. Multi-Sided Heating: Depending on the furnace size, in addition to ensuring furnace temperature uniformity as much as possible, additional options for multi-sided heating are provided to meet higher requirements for furnace temperature uniformity.

4. Multi-Point Temperature Control: Depending on different usage scenarios, customers can choose multi-sided heating to improve heat radiation efficiency and expand the coverage of furnace temperature.

5. Exhaust Ports and Gas Paths: Exhaust ports, gas paths, and flow meters can be added according to customer requirements to meet process requirements (without vacuum sealing structure).

6. Touchscreen Control: Y&H can produce touchscreen control systems based on popular industrial touchscreen interfaces in the market, allowing real-time observation, report generation, and data download.
