Material Load Softening Temperature Tester

Published: 3/14/2025

The Material Load Softening Temperature Tester is designed to measure the high-temperature load softening temperature range of ceramic refractory materials, graphite materials, and others. It complies with YB/T 370, GB/T5989, and ISO1893:1989 standards and offers multiple structures to meet different material testing needs.

Product Description

The CHY-II-17/16 Material Load Softening Temperature Tester can be used to test the high-temperature load softening temperature range of ceramic refractory materials, graphite materials, and others. The softening temperature under load indicates the material's resistance to simultaneous high temperature and load, and also characterizes the temperature range where the material exhibits significant plastic deformation. This device is manufactured according to the requirements of YB/T 370 "Test Method for Load Softening Temperature of Refractory Products (Non-differential Heating Method)" and also meets GB/T5989 and ISO1893:1989 "Test Method for Load Softening Temperature of Refractory Products (Non-differential Heating Method)". The CHY-II-17/16 offers multiple structures to satisfy the load softening temperature testing needs of different materials. Main technical parameters of the Material Load Softening Temperature Tester (two options: differential method and non-differential method):

  1. Heating temperature: maximum up to 1650℃; 1750℃ (two options available); corresponding usage temperatures: 1600℃, 1700℃; temperature control accuracy: heating stage less than ±2℃
  2. Heating rate: 0-20℃/minute; freely adjustable
  3. Heating mode: manual or automatic program heating; more than 30 program segments
  4. Deformation measurement range (mm): 0–10; deformation measurement indication error: no greater than 0.03mm
  5. Sample size: height 50±0.5mm; diameter 36±0.15mm; or height 50±0.5mm; diameter 50±0.35mm
  6. Uniform temperature zone height not less than 75mm; temperature difference no greater than 20℃
  7. Maximum power: 3.5KW to 6KW
  8. Sample load pressure: 0.2Mpa, 0.1Mpa, etc.
  9. Pressurization method selectable as direct pressure digital display; load range (N): 100–1000, accurate to 1N force
  10. The furnace body uses an open-type furnace body, making it very convenient to replace the upper and lower pressing rods; the independent loading system ensures higher loading accuracy
  11. Can connect to a computer for fully automatic control, Chinese operation interface, and automatic printing of test reports
