Problems solved by technology
When the high-temperature steel wire enters the low-temperature lead liquid, the cooling speed is relatively slow, which is not conducive to the smooth progress of austempering and affects the production quality of the steel wire
On the other hand, the lead liquid will evaporate to produce lead vapor, which is not environmentally friendly and harmful to the health of the staff.

The invention relates to a lead bath quenching furnace for steel wire heat treatment. The lead bath quenching furnace comprises a lead boiler body, a steel structure bracket, a steel wire branching roller, a lead pan, a wire inlet compression roller, a wire outlet compression roller and a wire outlet carrier roller, and is characterized by further comprising a molten lead circulating device and anair cooling device; the molten lead circulating device comprises a lead absorbing housing, a channel sealing plate and a lead discharging center; and the air cooling device comprises an air cooling heat exchange pipe set, an air cooler, a cold air inlet pipe set and a hot air outlet pipe set, the air cooling heat exchange pipe set is arranged in the lead pan and located below the lead liquid level, the air cooler is arranged beside the lead boiler body, an air outlet of the air cooler communicates with one end of the air cooling heat exchange pipe set through the cold air inlet pipe set, andthe other end of the air cooling heat exchange pipe set is connected with the hot air outlet pipe set. The lead bath quenching furnace is ingenious in structure and reasonable in design, through mutual cooperation of the molten lead circulating device, the air cooling device and a lead pan external heating device, the temperature of molten lead can be accurately controlled, the temperature of themolten lead is kept stable, and the steel wire production quality is improved.
Description
technical field [0001] The invention relates to steel wire production equipment, in particular to a lead bath quenching furnace for steel wire heat treatment, which belongs to the technical field of metal processing. Background technique [0002] In the process of producing steel wire, it is necessary to carry out heat treatment on steel wire, such as recrystallization annealing of steel wire, normalizing of steel wire and austempering of steel wire, etc. Traditional steel wire heat treatment furnaces include heating furnaces and austempering furnaces. When working, the steel wire runs continuously in the heating furnace and is heated to a certain temperature required by the process, and then it is cooled out of the furnace or enters the isothermal quenching furnace for quenching. In the conventional steel wire production process, after the steel wire is heated to about 750°C in a continuous heating furnace and then cooled in the air, it is called the steel wire recrystalli...
