2. Technical parameters
2.1 Specifications
1) Effective heating zone size - L1200×W800-H800mm
2) Loading capacity - 1000kg/batch (Including tooling)
3) Furnace height - ..00mm
4) Total weight- About 20T
2.2 Temperature parameter
1) Maximum temperature - 1320°C
2) Operating temperatur - 550°C~1280°C
3) Precision of controlling temperature - +1°C
4) Heating zone - Two sections
5) Furnace temperature uniformity- 5°C
(850°C, 1050°C. Empty furnace 9 points temperature measurement)
6) When full loading temperature rise from room temperature to 1150°C times
From room temperature to 500 Cr about 10°C/min. From 500°C to higher temperature could reach 20-30°C/min, When reach more higher temperature, temperature rise maybe reach 40-50°C/min. More higher temperature, more faster heat transfer speed, so more quicker temperature rise rate.
2.3 Vacuum performance

2) Working vacuum - .6.7×10 Pa
3) Leakage rate -0.5Pa/h
2.4 Tune parameters.
1) Empty fumace temperature rise time. 1200°C) $30min (From room temperature to
2) Pumping time - 25min (IX10 Pa 4 Pa)
3) Cooling chamber inflation time - 9-15
2.5 Electric parameters
1) Heating power - 260KW
2) Power of gas-cooling motor - 280KW
3) Whole equipment power - 620KW
2.6 Cooling performance
1) Cooling gas inflation pressure. 9x10 Pa (10bar)
2) Empty furnace temperature from 1200 °C to 500 °C - ≤4 min
3) Cooling rate when full loading from 1150°C to 500°C: 60°C Min.and it has ability to be controlled.
3) Capacity of gas storage tank - 15m²
4) Pressure of gas storage tank - 2.4MPa
2.7 Vacuum pump parameters
