Introduction: The instrument is used to determine the melting characteristics of coal ash. It is a silicon carbide tube for the heating element, in accordance with the provisions of GB GB / T219 automatic completion of the ash melting point of the heating process, can also be a certain range of control parameters to select and modify. There are optional heating procedures for other heating processes. Technical indicators: 1. Control: to single-chip as the core, automatically measure and correct the temperature and current, automatic phase-shift trigger thyristor closed Loop control heating current 2. Measuring range: 0-1600 ℃, resolution 1 ℃, with the value of thermocouple s 3. Time range: 0-999min, resolution 1min (1s less than 10min) 4. Heating rate: 900 ℃ before 15-20 ℃ / min, 900 ℃ after 5 ± 1 ℃ / min 5. Measurement error: ± 3 ℃? Timing error: <1s / h 6. Power supply: AC220V ± 10%, 50Hz? 7. Power: ≤ 6.5KW 8.
