Stainless steel wire annealing device

Abstract

The invention discloses a stainless steel wire annealing device. The stainless steel wire annealing device comprises an acid pickling pond, a hydrogen annealing furnace and an annealing cooling trough which are arranged in sequence. The acid pickling pond contains an acid solution used for removing oxide layers of stainless steel wires, a plurality of guiding plates are arranged in the acid pickling pond, each guiding plate is provided with a plurality of guiding holes formed evenly, and anti-wearing ring blocks where the steel wires penetrate are arranged in the guiding holes; communicating pipes, heat tracing wires and high temperature pipes are sequentially arranged in the hydrogen annealing furnace from top to bottom. The stainless steel wire annealing device further comprises a first solution supplying pond and a second solution supplying pond, and the first solution supplying pond and the second solution supplying pond are both connected with the annealing cooling trough. The stainless steel wire annealing device is provided with the two solution supplying ponds, the situation that a production line needs to be stopped when annealing solutions in the solution supplying ponds are replaced can be avoided, and production benefits are increased.

Description

technical field [0001] The invention relates to the technical field of metal processing, in particular to a stainless steel wire annealing device. Background technique [0002] Stainless steel wire needs to be annealed. If the residual stress after stainless steel processing is not eliminated in time, it will often lead to cracking of the steel. The semi-finished steel wire after drawing has residual internal stress, which must be annealed to eliminate internal stress, so as to prevent cracking and eliminate work hardening, so as to facilitate continuous processing. Hydrogen annealing furnace is a commonly used annealing equipment for stainless steel wire. However, when the stainless steel wire passes through the conduction pipe of the hydrogen annealing furnace, due to the oxide layer on the surface of the steel wire, the oxide layer falls off in the conduction pipe and easily leads to conduction. The blockage of the pipe will increase the maintenance cost, which is not c...

Hydrogen annealing furnace is a commonly used annealing equipment for stainless steel wire. However, when the stainless steel wire passes through the conduction pipe of the hydrogen annealing furnace, due to the oxide layer on the surface of the steel wire, the oxide layer falls off in the conduction pipe and easily leads to conduction. The blockage of the pipe increases the maintenance cost and is not conducive to production and use

In addition, in the existing stainless steel wire annealing equipment, the annealing liquid in the annealing cooling tank is supplied by the pump in the liquid supply pool, and then is sent back to the liquid supply pool by the pump in the annealing cooling tank to form a cycle to achieve the purpose of saving, but Since the annealing liquid in the liquid supply pool needs to be replaced every once in a while, the production line is shut down and the production efficiency is affected
