Annealing furnace steam protection device

Abstract

The invention discloses a steam protection device of an annealing furnace. The steam protection device comprises a cylindrical steam storage bag and a plurality of annealing furnace pipes. The multiple annealing furnace pipes are laid in parallel at equal intervals, and all the annealing furnace pipes penetrate the steam storage bag in the horizontal direction and are in sealed connection with the steam storage bag. The two ends of the steam storage bag are provided with steam inlet pipes, and the lower end face of each annealing furnace pipe is provided with steam inlet holes. The lower end of the steam storage bag is provided with a drain pipe which is used for draining accumulated water in the steam storage bag, and the drain pipe is provided with a drain valve. A metal protection cover is arranged on the periphery of the steam storage bag. According to the steam protection device, the annealing furnace pipes are laid side by side at equal intervals and penetrate the steam storage bag in the horizontal direction, the lower ends of the furnace pipes are provided with the steam inlet holes, steam enters the annealing furnace pipes from the lower portions, the drain valve is arranged at the lower end of the steam storage bag, and the accumulated water in the steam storage bag is automatically drained; the structure is exquisite and simple, the design is ingenious, the instability phenomenon of copper wire annealing is avoided, the copper wire annealing effect is good, and the defect rate of products is greatly reduced; and the protection cover is arranged on the periphery of the steam storage bag, and tidiness and attractiveness are improved.

Description

technical field [0001] The invention relates to the technical field of copper material processing, in particular to a steam protection device for an annealing furnace. Background technique [0002] In the manufacturing process of copper wire, annealing is an important process. The copper wire is slowly heated to a certain temperature, kept for a sufficient time, and then cooled at an appropriate speed. The purpose is to reduce hardness, eliminate residual stress, stabilize size, reduce deformation and crack tendency; refine grain, adjust structure and eliminate structure defects. At present, there are two types of annealing furnace steam protection devices: one is an annealing furnace steam protection device for thicker copper wires; the other is an annealing furnace steam protection device for thinner copper wires. However, most of the annealing steam protection devices currently on the market have problems: 1. The amount of steam entering each furnace tube is uneven, resu...

Problems solved by technology

However, most of the annealing steam protection devices currently on the market have problems: 1. The amount of steam entering each furnace tube is uneven, resulting in unstable annealing of multiple copper wires in the whole machine; 2. The joints of the steam storage drum are easy to Water leakage and steam leakage occur, resulting in unstable annealing of copper wires; 3. Serious water accumulation in each furnace tube leads to serious water in copper wires, resulting in unstable annealing of copper wires; 4. Water is easy to accumulate in the steam storage drum, causing copper wires to Severe water, resulting in unstable annealing of copper wire; 5. Exposure affects appearance
