Hybrid Furnace

　　The Hybrid Furnace, which integrates tube furnace and box furnace, is a hybrid electric furnace that combines the advantages of tube furnace and box furnace. Its design aims to meet diverse experimental and production needs, achieve functional complementarity through modular structure, and is suitable for scenarios such as material sintering, heat treatment, and atmosphere control. The following analysis will be conducted from four aspects: structural characteristics, functional advantages, application scenarios, and selection suggestions: 1. Structural features: modular integration, complementary functions Tube furnace module Core structure: The furnace tube is made of quartz or corundum material, with sealed flanges at both ends, supporting vacuum pumping or the introduction of protective gases (such as nitrogen and argon). Heating method: Resistance wire, silicon carbon rod or silicon molybdenum rod are arranged around the furnace tube to achieve radial uniform heating. Temperature control: Supports programmed temperature control, with a temperature range typically from 300 ℃ to 1700 ℃ and a temperature control accuracy of ± 1 ℃. Box type furnace module Core structure: Square furnace, door opening in front, internal splicing of refractory fiber modules to reduce rapid cooling and heating cracks. Heating method: The top and bottom heating elements work together, and the hot air circulation system enhances temperature uniformity. Temperature control: Microcomputer programmed temperature control, supporting multiple heating curves, with a maximum temperature of 1800 ℃. integrated design Shared system: Integration of power supply, control system, vacuum pump and other components to reduce equipment footprint. Independent operation: Tube furnaces and box furnaces can operate separately or in combination to meet different process requirements. 2. Functional advantages: flexible and efficient, strong adaptability Process flexibility Tube furnace: suitable for high-temperature sintering and atmosphere protection experiments of small particle materials such as ceramic powder and glass powder. Box furnace: processes such as heat treatment, quenching, tempering, etc. for processing large workpieces (such as stainless steel target materials). Joint mode: Continuous operation of tube furnace vacuum treatment and box furnace high-temperature annealing is achieved through valve switching. energy efficiency Tube furnace: Quartz tubes have good heat permeability and high heating efficiency, suitable for rapid heating scenarios. Box type furnace: Double layered furnace sleeve and air-cooled heat dissipation design, reducing shell temperature (≤ 50 ℃) and minimizing heat loss. Hybrid mode: dynamically adjust power allocation and optimize energy consumption according to process requirements. Convenience of operation Intelligent control: supports 2 sets of 30 segment program programming, with adjustable parameters during operation, and real-time monitoring of temperature curves. Safety design: Multi point locking mechanism for furnace door, over temperature alarm, leakage protection and other functions ensure safe operation. 3. Application scenario: Cross industry coverage to meet diverse needs Materials Science Ceramic sintering: Tube furnace processes nano ceramic powder, and box furnace sinter large ceramic components. Metal heat treatment: The box furnace is used for aluminum alloy aging treatment, and the tube furnace is used for vacuum quenching of steel parts. Chemical Industry and New Energy Lithium battery materials: Tube furnace synthesis of positive and negative electrode materials, box furnace calcination of precursors. Catalyst preparation: The catalyst is activated by introducing reducing gas into the tube furnace, and the carrier is sintered at high temperature in the box furnace. Semiconductors and Electronics Crystal growth: Thin films are deposited by tube furnace CVD method, and wafers are annealed in box furnace. Packaging test: Vacuum packaging of tube furnace, aging test of box furnace. 4. Selection suggestion: Configure as needed, balancing performance and cost Process requirement matching Small batch experiment: Prioritize the use of tube furnace modules, while balancing vacuum and atmosphere control. Large scale production: Strengthen the box furnace module and equip it with an automated loading system. Composite process: Choose the tube box joint mode to support continuous production.
