Application:

Horizontal continuous casting machines for copper are widely used in industrial production, mainly for continuous casting of pure copper (red copper) and copper alloys (such as brass, bronze, etc.), producing semi-finished products such as bars, tube billets, and flat ingots, and providing high-quality billets for subsequent processing (such as extrusion, rolling, and drawing). The following are its main application areas and typical products:

1. Electrical and electronic industry

High-purity oxygen-free copper (OFHC)

Used in the manufacture of wires and cables, electromagnetic wires, transformer windings, etc., requiring extremely low oxygen content (≤10ppm) and high conductivity (≥101% IACS).

Product form: round bars (Φ8mm~Φ30mm), flat ingots (for rolling copper strips).

Copper alloy lead frames

Such as copper-iron alloys (C19400), copper-chromium-zirconium (C18150), etc., are used for integrated circuit lead frames. Horizontal continuous casting can reduce component segregation.

2. Copper alloy profiles and pipes

Brass (H65, H68, etc.)

Rods (Φ20mm~Φ100mm) for bathroom accessories, valves, and locks. Horizontal continuous casting can control zinc volatilization and ensure uniform composition.

Bronze (such as tin-phosphor bronze C5191)

Flat ingots for casting wear-resistant bushings and shrapnel, and then cold-rolled into strips.

Copper tube billets

Horizontal continuous casting hollow ingots (need to match hollow crystallizers) are used for the production of air conditioning refrigeration pipes and water pipes.

3. High-end equipment manufacturing

High-speed rail contact wire (copper-magnesium alloy, copper-silver alloy)

Horizontal continuous casting can reduce pores and inclusions, and improve the fatigue resistance and conductivity of the wire.

Vacuum coating target

Dense ingots of high-purity copper or copper alloys (such as copper indium gallium selenide, CIGS) are used for solar thin film coating.

4. Copper materials for special purposes

Special-section ingots

Production of non-standard sections (such as square and hexagonal) through customized crystallizers to reduce subsequent processing allowances.

Composite copper materials

Such as core material casting of copper-clad aluminum and copper-clad steel, metallurgical bonding is achieved by horizontal continuous casting.

5. Recycling of recycled copper

Direct continuous casting of scrap copper

The scrap copper (such as scrap wire and copper scraps) recycled by smelting is regenerated into billets through horizontal continuous casting to reduce energy consumption and metal loss.

Technical advantages and selection points

Applicable alloys: pure copper, brass (zinc content ≤ 40%), bronze, white copper (nickel segregation needs to be controlled).

Inapplicable scenarios: ultra-high zinc brass (such as H59, zinc is volatile), lead-containing easy-to-cut copper (lead is easy to segregate), etc.

Production capacity range: small and medium batches (single-line annual output of 10,000 to 50,000 tons), suitable for flexible production of multiple varieties.

The horizontal continuous casting machine achieves a balance of high efficiency, low oxidation and stable composition in the copper processing field through sealed melting, precise temperature control and continuous forming. It is an important choice to replace traditional mold casting or vertical continuous casting.

Product Features:

The horizontal continuous casting unit consists of the melting furnace, holding furnace, crystallizer, casting machine, on-line 

cutting machine and electric control system. It is mainly used for melting, holding and casting pure copper or brass. The horizontal continuous casting furnace has two kinds of structure: combined and separated. It is designed most appropriate according 

customers’ needs.

According to the melting capacity, one or two sets melting furnaces can be designed. The melting furnace is of vertical structure, 

and the melting furnace is arranged on both sides of the holding furnace.  There is a group of melting channel type inductor 

equipped on the back side of the holding furnace. It can continuously add the copper liquid to the holding furnace.

The raw material is added into the melting furnace, then melted to the working temperature by the melting channel type inductor,and then the bottom copper liquid flows out through the teapot spout type rotating mouth of the melting furnace, and then flows

into the holding furnace through the sealed flow channel. It can improve the quality of finished ingot.  

the continuous horizontal combined furnace adopts the under cannel combined structure. The melting furnace uses the under channel to supply copper liquid to the holding furnace, which avoids the heat emission of copper liquid when passing through 

the flow channel, and reduces the power consumption and copper material loss. The copper liquid has little contact with air, 

which is beneficial to stabilize and improve the quality of ingot.
