Hongbo Group Shines at SMM CCAE 2026 (15th) Copper Industry Conference

As the first year of the "15th Five-Year Plan," 2026 marks a critical stage for the global copper industry, characterized by supply-demand restructuring, technological innovation, and green transformation. Constrained by resources, costs, and geopolitics, copper supply growth remains limited. Meanwhile, new energy, new-type power grids, and AI computing power are driving substantial copper demand, widening the supply-demand gap and heightening copper's strategic value. Leveraging the "Implementation Plan for High-Quality Development of the Copper Industry (2025–2027)," China's domestic copper industry is accelerating its high-end, intelligent, and green transformation.

Against this backdrop, , will be held on October 28-30 at the Shangri-La Hotel, Nanchang, Jiangxi. Shanghai Metals Market (SMM), together with Jiangsu Hongbo Gas Equipment Technology Group Co., Ltd., invites you to attend. The conference focuses on the high-quality development of the copper industry, bringing together stakeholders from industry, research, and finance to discuss technological innovation and resource synergy, thereby shifting China's copper industry from scale advantage to dual leadership in technology and value.

Application of Nitrogen Generators in the Entire Copper Processing Industry Chain (Primarily PSA Nitrogen Generation, with Purification Units and Hydrogen-Nitrogen Ratio Control)

Copper easily oxidizes, blackens, rusts, and forms scale at high temperatures. Nitrogen, as an inert protective gas, isolates oxygen and moisture and is an essential gas source for melting and casting, wire drawing, annealing, copper pipe & tube and strip, electronic copper foil, and furnace purging. On-site nitrogen generation replaces liquid nitrogen/nitrogen cylinders, significantly lowering gas costs.

Product Introduction

Fully Automatic PSA Nitrogen Generator

Nitrogen purity adjustable 99.5%–99.999%

Flow rate 5–1,000 Nm³/h

PSANitrogen Generator + Carbon Deoxidation Purification Unit

Nitrogen oxygen content 1–10 ppm

Flow rate 30–1,000 Nm³/h

Nitrogen dew point ≤ -60°C

PSANitrogen Generator + Hydrogenation Deoxidation Purification Unit

Nitrogen oxygen content 0.3–10 ppm

Flow rate 30–1,000 Nm³/h

Nitrogen dew point ≤ -60°C

Ammonia Decomposition Hydrogen Generation and Fully Automatic Hydrogen-Nitrogen Ratio Control Unit

Hydrogen content optionally adjustable

Ratio precision ≤ ±0.5%

Flow rate 5–350 Nm³/h

Advantages of the Nitrogen Generator Solution (Compared with Externally Purchased Liquid Nitrogen)

1. Continuous and stable gas supply, eliminating the risk of production halts due to gas interruptions;

2. Long-term operating cost only 1/3 to 1/4 of liquid nitrogen;

3. Pressure, purity, and flow rate automatically adjustable, matching the operating conditions of annealing furnaces/melting furnaces;

4. Skid-mounted integrated design, adapted to the dusty and high-temperature environment of copper plants, supporting 24-hour unattended operation.

I. Melting and Casting Process (Upward-drawing copper rod, continuous casting, medium-frequency melting)

1. Liquid surface sealing protection for melting furnace

2. Furnace body replacement, furnace washing, purging

3. Nitrogen protection specifically for upward-drawing bare bright copper rod

II. Bright Annealing (The largest gas-consuming station in the copper industry)

After cold working, copper wire, copper strip, copper pipe & tube, copper busbar, brass/phosphor bronze harden; annealing at 400–650℃ to relieve stress. Without nitrogen protection, the surface becomes black and scale forms.

III. Wire Drawing, Copper Foil, and Precision Copper Semis Production

1. Intermediate annealing for heavy/medium/micro drawing

2. Electronic copper foil, ultra-thin copper strip

3. Hollow copper pipe & tube, precision alloy copper

IV. Other Supporting Process Applications

1. Sintering of powder metallurgy copper parts

2. Finished product packaging, anti-oxidation storage

3. Hydraulic/pneumatic purging, leak detection
