Title:
INVAR WIRE HEAT TREATMENT APPARATUS AND METHOD
Document Type and Number:
WIPO Patent Application WO/2024/078162
Kind Code:
A1
Abstract:
Provided in the present invention are an invar wire heat treatment apparatus and method. The invar wire heat treatment apparatus provided in the present invention comprises a continuous heating furnace, wherein the heating furnace is provided with a hearth, which is heated by means of open fire combustion so as to perform continuous heat treatment on a steel wire, a flue gas guide tunnel is provided in each side wall of a furnace body on two opposite sides of the hearth, a plurality of heat treatment pipes, which extend through front and rear ends of the furnace body and are configured to heat an invar wire, are provided in each flue gas diversion tunnel, and the flue gas diversion tunnel in each side wall is in communication with a rear end of the hearth, so that high-temperature heat treatment on a high-carbon steel wire and medium-temperature heat treatment on the invar wire can be performed at the same time. In the present invention, a temperature gradient difference is designed, and continuous heat treatment on the invar wire is performed by using waste heat of the steel wire heating furnace body and waste heat of flue gas, so that the waste heat is fully exchanged, the smoke exhaust temperature is low, and the aims of increasing the quality, improving the efficiency, saving energy and reducing the cost can be achieved; and compared with an offline heat treatment method, the manufacturing cost of the invar wire is obviously reduced.
