High-Temperature Devices

High-temperature furnaces for tests in a temperature range from +200°C to 1,600°C are used to determine the thermal-elastic behavior, heat resistance and re-crystallization temperature of materials.

High temperature furnace 200°C to 1,600°C

Key Advantages and Features

  • Zwick offers an array of solutions, with a minimum temperature of 200°C and a maximum temperature of 1,600°C
  • Depending on the materials to be tested, 1-zone or 3-zone furnaces with air or vacuum environment are available
  • Zwick solutions feature optimal coordination of furnaces (including temperature controllers), the correct specimen grips for tensile and flexure tests, and the appropriate extensometer
  • The high-temperature furnaces and extensometers are provided with swivel units, allowing comfortable, convenient operation of the testing machine, which can then be used for room-temperature testing with practically no reconfiguration
  • An optional specimen temperature measuring device with up to three thermocouples is available for direct temperature measurement on the specimen, ensuring standard-compliant testing at temperature.

Temperature-controlled progressive load tests on cast iron materials

To characterize the specific properties of gray cast iron (cast iron containing lamellar graphite) the Austrian Foundry Research Institute (ÖGI) is carrying out progressive load tests at both room temperature and elevated temperatures. Progressive tensile tests using a Zwick 100kN AllroundLIne testing machine are designed to determine the temperature dependence of Young's modulus and of the static E0 modulus of gray cast iron.
