Installation Guidelines

Proper installation method for vertical hanging of U-shaped heating elements

Vertical Hanging Method

Due to the material's brittleness at room temperature and plasticity at high temperatures, U-shaped elements should be vertically suspended from the furnace top using support clamps. This prevents mechanical stress on the heating zone and minimizes breakage risk.

Support Clamp Requirements

Specialized clamps are required for 9/18 and 6/12 elements. Proper installation ensures vertical alignment and even heat distribution. The tapered lower end must extend fully into the furnace chamber to prevent localized overheating.

Application Range

1700 Type: Suitable for operations up to 1700°C
1800 Type: Suitable for operations up to 1800°C
1800J Type: For temperatures ≥1800°C (Φ3-12mm W-type)
1800T Type: For temperatures ≤1800°C (Φ3-12mm W-type, U-type)
