Analysis of the core features and technical advantages of vacuum furnaces

Efficient energy saving and environmental protection characteristics

Low energy consumption performance: The vacuum furnace uses high-quality insulation materials to build the heating chamber, and concentrates electrical energy in the heating area through insulating walls and barriers. The energy consumption is significantly lower than that of traditional salt bath furnaces, and the energy saving effect is obvious.

Pollution-free environment: No waste treatment is required, and there is no harmful emission during the heating process, which meets the environmental protection requirements of modern industry.

Zero water pollution: Built-in stainless steel heat exchanger to avoid pollution to the heating medium or workpiece.

Safe, reliable and long-life design

Negative pressure safe operation: Most vacuum furnaces work under negative pressure environment, without explosion risk, and are national inspection-free products.

Structural optimization to improve life: The high temperature zone and high pressure zone of the stressed steel plate are successfully separated, which prolongs the service life of the equipment by 2-3 times, and the design life can reach decades.

Sealing and cooling guarantee: The movable connection part is sealed with O-type rubber ring and cooled by water, and the furnace shell is cooled by water or air to prevent deformation and deterioration of sealing materials.

High-precision and intelligent control

Precise temperature control: Thermocouple temperature measurement accuracy reaches ±1.5℃, and with rarefied gas forced circulation technology, the temperature difference in the furnace can be controlled within the range of ±5℃.

Mechatronic operation: Workpiece movement, air pressure regulation, power control and other processes can be pre-programmed to achieve automated execution of quenching, tempering and other processes.

Remote and unattended: Support intelligent, unmanned operation or remote network control to improve production efficiency.

Compact structure and high-efficiency performance

High space utilization: The overall design is scientific and compact, and the floor space is saved by 2/3 compared with traditional equipment.

Fast preheating and heat exchange: Direct heat exchange in the furnace body, the thermal efficiency of the whole machine exceeds 90%, and hot water can be provided within 2-3 minutes after startup, shortening the preheating time.

Multi-functional adaptability: It can realize vacuum quenching, tempering, annealing, brazing, sintering and other processes to meet the needs of multiple fields such as metals, electronics, and medical devices.

Process adaptability and operating specifications

Gas selection and control: Different cooling gases are selected according to the material characteristics, such as 99.995% nitrogen for steel and 99.995% argon for titanium alloy to avoid high temperature reactions.

Vacuum standard: The pressure rise rate of domestic equipment is ≤1.33Pa/h, and the foreign advanced standard is 0.67Pa/h to ensure the stability of the processing environment.

Maintenance requirements: When idle, it is necessary to maintain a vacuum or pure nitrogen state to prevent air and moisture absorption from affecting performance.

Vacuum furnaces have become key equipment in the field of modern industrial heat treatment by integrating safety, efficiency and intelligent technology. Their applications in metal modification, precision manufacturing and other scenarios are constantly expanding.
