Dilatometer DF-4

Overview

• Swelling rate (increase in volume when heated) is an important indicator of the quality of coal for coking. It is determined by a standard dilatometric test.
• From the expansion curves the following numerical parameters of the tested coal samples can be deduced:
  • Softening Temperature
  • Temperature of maximum contraction
  • Temperature of maximum dilatation
  • Value of maximum contraction
  • Value of maximum dilatation

Features

• High productivity of measurement
• One measuring cycle = Four samples measured at once
• Contact less measuring of measuring pistons movement (dilatation)
• Fully automated performance
• One measuring cycle lasts for approx. 120 minutes
• Course of the test controlled by Computer
• Real time monitoring of complete measuring process
• Auto-diagnostics of the equipment
• Measurement of temperature of each dilatation measuring tube
• Precise digital control of furnace unit
