Furnace, chamber & vacuum heating system
High-Temperature Furnaces are ideal for a wide variety of high-temperature tests, including tension, compression, bend and fatigue testing of metals, composites, ceramics and many other materials. The furnaces have a user-friendly design that helps operators perform setup tasks more quickly – without compromising test quality or accuracy.
Vacuum chamber is an industrial furnace that uses a vacuum system to discharge substances inside the chamber. The chamber pressure is reduced to below standard atmospheric pressure through components such as vacuum pumps, measuring devices, and valves. It can be directly heated by electric resistance furnace wires (such as tungsten wires) or by high-frequency induction heating, with a heating capacity up to 3000 ℃.

Application Field
In material mechanics performance testing, the ultra-high temperature and special environment simulation test system, namely the high-temperature vacuum (inflatable environment, etc.) test device, is mainly used in national defense and military industry, aerospace, modern space technology, nuclear fusion reactor engineering, and new materials research departments.
New materials are almost exclusively used in high-tech fields, so the requirements for performance and lifespan are even more stringent. Unconventional material mechanical performance tests, such as tensile, compressive, bending, shear (interlaminar shear), peel, torsion, fatigue (low cycle high cycle), creep endurance, impact, and hardness tests, are almost all required for new materials, and most require testing of their material mechanical properties under high temperature and other environmental conditions. New test methods are constantly being added, such as high-temperature fracture mechanics test, variable temperature creep fatigue test, etc.
Development history
The development of vacuum furnaces play a crucial role in human progress.
In the Shang Dynasty (BC1600-BC1046), China developed a relatively complete copper smelting furnace with a temperature of 1200 ℃ and an inner diameter of 0.8 meters.
During the Warring State Period(BC770-BC210), Chinese people further mastered the technology of increasing furnace temperature based on copper melting furnaces, thus producing cast iron.
In 1794, John Wilkinsona developed the straight cylindrical blast furnace (cupola) for melting cast iron and applied a patent in Britian.
In 1855, British engineer Karl William Siemens (1823-1883, originally from Germany) invented a high-temperature flame furnace equipped with a heat storage chamber and obtained a patent in 1856. This furnace was first used for melting glass.
In 1864, Frenchman PiereEmile Martin used the principle of Siemens’ regenerative furnace from Britain to build the first steelmaking open hearth furnace heated by gas fuel(Siemens-Martin furnace). He used a heat storage chamber to preheat the air and gas at high temperatures, ensuring a temperature of over 1600 ℃ required for steelmaking.
Around 1900, the supply of electricity gradually became sufficient, and various resistance furnaces, electric arc furnaces, and core induction furnaces began to be used.
Vacuum furnaces appeared around the 1930s.
In 1927, the United States produced a vacuum annealing furnace for electrical materials.
In 1953, vacuum consumable electric arc furnaces were used in industry for melting sponge titanium. Vacuum induction furnaces were widely used in industry around the 1950s.
In 1960, the United States developed an oil quenching vacuum furnace.
In 1969, SINOTEST started to develop high-temperature vacuum system.
In 1984, SINOTEST successfully developed the first high temperature vacuum tensile creep testing machine CJS-9 model, the highest temperature capacity of 1600℃ in China.
In 2012, SINOTEST successfully developed a 900 ℃ vacuum three-point bending test device for ceramic materials。
In 2017, SINOTEST successfully developed a 1000 ℃ vacuum multi-station creep testing device.
