Temperature Field Specification |
The maximum temperature point inside the furnace deviates from the geometric center of the furnace by no more than 20mm, and within ±20mm of the maximum temperature point, there is a uniform temperature field with a temperature gradient ≤ 0.4 ℃/10mm. |
Within 30mm axially from the bottom of the hole, the temperature difference shall not exceed 0.5℃; the absolute value of the temperature difference between any holes in the same cross-section at the bottom of the hole shall ≤ 0.25℃. |
Within the axial 30mm of the effective working area, the absolute value of the temperature difference between any two points shall ≤0.5℃; within the radial radius of not less than 14mm, the absolute value of the temperature difference between any two points on the same cross-section shall ≤0.25℃. |
