Description

Technical Field

[0001] The utility model belongs to the field of nonferrous metal smelting, in particular to a copper hawk beak for a suspension converting furnace. Background Art

[0002] The suspension converting furnace at Henan Zhongyuan Gold Smelter began operation in August 2015. The original design for the copper tapping system used a prefabricated component and castable material to guide blister copper from the converting furnace chute to the anode refining furnace. However, due to the non-integrated structure between the prefabricated component and the castable material, gaps easily formed during temperature fluctuations, leading to copper leakage. Furthermore, the bottom of the anode refining furnace was prone to blister copper sticking and castable material cracking. The prefabricated and castable tapping system typically required replacement and recasting after only about two weeks of use, with a cumulative copper discharge of less than 3,000 tons. The short service life and frequent replacement of the tapping system severely impacted the safety of copper tapping operations and production continuity in the suspension converting furnace.

[0003] According to incomplete statistics, existing copper tapping systems for suspension converting furnaces mostly utilize various methods, including chute extension, prefabricated casting, and high-alumina brick masonry. However, these systems generally have a short service life of approximately one week, severely impacting the safety and continuity of suspension converting furnace operations. From August 2015 to March 2021, our company's suspension converting furnaces experienced over 100 interruptions due to copper tapping system failures, necessitating multiple reductions in throughput. This significantly increased the workload for our employees and severely limited the company's sustainable development.

[0004] Therefore, providing a safe, reliable and durable copper eagle beak is an issue worthy of study. Utility Model Content

[0005] In order to overcome the defects of the prior art, the utility model provides a copper hawk beak for a suspension converting furnace.

[0006] Based on the above purpose, the present invention adopts the following technical solutions:

[0007] A copper discharge beak of a suspension converting furnace comprises a chute connected to the copper discharge port of the suspension converting furnace and a beak connected to the other end of the chute, the end of the beak being connected to an anode refining furnace, guard plates being provided on both sides of the beak and the inside of the chute, a sealing plate being provided at the end of the beak close to the anode refining furnace, an integrally casted casting material being provided in the beak and the chute, a groove being provided in the middle of the upper end surface of the casting material, the groove serving as a copper discharge channel, the end of the copper discharge channel being connected to the copper inlet of the anode refining furnace so that the crude copper melt of the suspension converting furnace flows into the anode refining furnace.

[0008] Furthermore, the eagle's beak and the chute are both enclosed by a bottom plate and two side plates fixed on both sides of the bottom plate, and the bottom plate of the eagle's beak has a certain curvature from the chute to the anode refining furnace.

[0009] Furthermore, the height of the guard plate is lower than that of the eagle beak or chute, and the guard plate is a right-angled trapezoid, one right-angled side of the guard plate is fixed to the side plate of the eagle beak or chute, and the other right-angled side of the guard plate is fixed to the bottom plate of the eagle beak or chute.

[0010] Furthermore, the sealing plate is in a concave shape, the notch in the middle is a copper placement channel, and the two sides are flush with the top of the eagle's beak.

[0011] Furthermore, flanges are provided on outer walls of two side plates at one end of the chute close to the suspension converting furnace.

[0012] The utility model designs an eagle beak, welds the eagle beak and the chute together, and installs a guard plate inside the eagle beak and the chute to make them a rigid structure; the new copper-laying eagle beak can be prefabricated in advance, ensuring sufficient curing time for the castable, and at the same time, replacement is more convenient and quick.

[0013] The beneficial effects of the utility model are:

[0014] (1) The copper discharge hawk beak is adaptable to the high-temperature flue gas of the anode refining furnace and the crude copper melt of the suspension converting furnace, avoiding the weaknesses of the copper discharge hawk beak composed of prefabricated parts + castables, such as easy copper leakage, easy adhesion, and frequent replacement. The phenomenon of suspension converting furnace copper discharge operation being suspended due to copper discharge hawk beak problems is eliminated, thereby improving the safety of suspension converting furnace copper discharge operation and ensuring the continuity of suspension converting furnace production.

[0015] (2) The service life of the eagle beak and the chute has been improved. Now the service life of a single copper-discharging eagle beak can reach 4 months, and the cumulative copper discharge volume can reach more than 25,000 tons, which is a major breakthrough in service life.

[0016] (3) The copper eagle beak of the suspended blowing furnace can be prefabricated in advance, and the curing time is longer, so that the strength of the castable can be fully exerted. BRIEF DESCRIPTION OF THE DRAWINGS
