Lead Patenting Furnace manufactured by United Enterprises is a continuous wire heat treatment system where high-carbon wire is heated to 950C and then quenched in a molten lead bath at 550C, producing a fine-grained patenting sorbite structure.
Brief Description:
Lead patenting is the traditional and proven route for producing high tensile drawn wire for prestressing strands, springs, ropes and tyre cord. Our Lead Patenting Furnaces are built for continuous, dependable operation with tight temperature control and good metallurgical consistency.
The system integrates the heating furnace, lead bath, pickling, galvanizing (optional) and take-up units. Electric or gas-fired heating versions are available, with PLC and SCADA-based control across the line.
Each line is built around the customers wire size range, throughput and downstream drawing requirements.

FAQs:
Q: How is lead handled safely?
A: Safety enclosures, fume hoods, exhaust scrubbing and operator protective practices are designed in line with the customers safety policy.
Q: What downstream operations can be added?
A: Pickling, galvanizing, phosphating and drawing equipment can be integrated as part of a turnkey line.
Q: Do you offer salt-bath alternatives?
A: Yes. Where lead is restricted, salt-bath or fluidised-bed patenting systems can be supplied instead.
