Description

Technical Field

[0001] This utility model relates to the field of heat treatment equipment technology, and more specifically, it relates to a spheroidizing furnace for steel production. Background Technology

[0002] Steel wire coils, as the most commonly used raw material in fastener production, require spheroidizing annealing during heat treatment before processing to meet pre-processing performance requirements. Because steel wire coils are cylindrical with large gaps between adjacent coils, placing heat sources in these gaps can accelerate the heating process and prevent high losses due to heat sources positioned on the furnace wall. Therefore, this invention proposes a spheroidizing furnace for steel production. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a spheroidizing furnace for steel production, which has the characteristics of low heat loss and strong specialization.

[0005] The present invention is further configured such that: the electric heating assembly includes a first heating rod extending from bottom to top, a second heating rod extending from top to bottom, and a heating elbow connecting the first heating rod and the second heating rod, wherein the first heating rod and the second heating rod pass through all the heat-conducting discs in sequence.

[0006] The present invention is further configured such that the outer walls of the first heating rod and the second heating rod are in contact with the heat-conducting disc.

[0007] The present invention is further configured such that the diameters of the heat-conducting discs are all equal.

[0008] The present invention is further configured such that the outer surface of the heat-conducting disc is close to the inner wall surface of the spheroidizing furnace cavity.

[0009] The present invention is further configured such that the spacing between two adjacent heat-conducting discs is equal.

[0010] The present invention is further configured such that the included angle between two adjacent working holes is equal.

[0011] In summary, this utility model has the following beneficial effects:

[0012] 1. The working holes arranged on the heat-conducting positioning frame can be used for heat treatment of coiled steel wire, preventing the coiled steel wire from tipping over, and the surrounding heat source is close, resulting in a fast heating rate.

[0013] 2. The heat source is located near the raw materials and at a certain distance from the furnace wall, so it does not act directly on the furnace wall, resulting in low heat loss and high utilization rate. Attached Figure Description
