Description

Technical Field

[0001] The invention relates to the technical field of industrial processing, in particular to a salt backflush device at a salt bath tank outlet. Background Art

[0002] Nowadays, the requirements for high performance and low cost of steel wire products are getting higher and higher. Ultra-high strength steel wire is made of high-carbon pearlite wire rod through continuous multi-pass cold drawing deformation. Due to its ultra-high strength and good plasticity, it is widely used in many important fields. Now a more reasonable processing method is to transform the steel wire from austenite to troostite by salt bath at a suitable temperature.

[0003] After the steel cable is in the salt bath, it needs to be desalted and cleaned. The traditional way is to use high-speed airflow to blow the crystallized salt back into the salt tank, so as to recycle industrial salt and reduce production costs. However, the current back-blowing device at the salt bath tank outlet generally uses a high-pressure fan to blow out high-temperature airflow to achieve this.

[0004] This means that in the actual operation process, since the overall cross-section of the steel cable is roughly circular, there are dead corners when the high-pressure fan is used to blow back the salt, and the salt at the bottom of the steel cable is not completely cleaned. At the same time, when the steel wire passes through the salt bath tank outlet, it is easy to cause scratches on the steel wire due to the bending angle of the steel cable. For this reason, a salt bath tank outlet salt backblowing device is specially provided to solve the above problems. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the present invention discloses a salt backblowing device at a salt bath tank outlet to solve the problem raised in the above background technology that, during actual operation, since the overall cross-section of the steel cable is roughly circular, when the high-pressure fan is used to blow back the salt, there are dead angles for blowing, and the salt at the bottom of the steel cable is not thoroughly cleaned.
