Lead quenching unit

Lead quenching unitKnown as classical products in the industry, the lead baths have acquired a very good reputation among big producers. The FIB lead bath has evolved year after year and has been adapted in order to meet the requirements of patenting at high temperature as requested for the production of "High Tensile" tire cord as well as the pressure of the strict respect of the polluted emissions that is frequently required by wire drawers.

Thanks to a system of hood, to lead circulation pumps at high temperature and to a technique for elaborating materials that are specific to the requirements of the patenting temperatures, FIB has supplied more than 150 tanks throughout the world !

The wire drawers working with big wires have not been forgotten as FIB has developed some years ago a patenting system for big wires (25 mm diameter) based on the overflow of lead and the passage of wires without inflexion.

Advantages :

- Modular furnace: easy upgrade of the equipment
- Multigas combustion equipment
- Pre-bricked sections: allows to minimize the assembly operations
- Improvement of the lead-wire heat exchange by a special design specific to FIB
- Allows a perfect homogeneous quenching of wires even for a large diameters
- Diameter range: from 0,8 mm up to 18 mm
- High velocity burners: 130 m/s is the speed of combustion fumes at the exit of the burner brick
- Gas or electrical heating available
- Design exist for high temperature lead quenching operation
- Lead overflow technology available for very large wire sizes
- One tuning of air gas ratio set point per zone
- Special covers available for severe environmental specifications
