Copper wire rod continuous casting machine

Types of Copper Wire Rod Continuous Casting Machines

A copper wire rod continuous casting machine is an industrial machine that casts copper metal in a continuous manner into rod copper. Therefore, different types of machines are usually used for casting copper continuously to form rods or wires. One popular continuous casting machine for copper alloy is the Conarc machine or continuous casting and rolling machine. The Conarc machine consists of an immobile vertical water-cooled copper moulds that have simulated inverted T-shaped cross-sections. The copper alloy is molten inside a furnace, then the molten alloy is poured into the copper moulds for cooling and solidification. The solidified Copper is then extracted from the mould in a continuous rolling process.

Another popular type of continuous casting machine is the Purl machine. The Purl method of casting copper utilizes a bottom-up continuous casting technique. Firstly, a metallic mold is cooled by water and is submerged in the molten copper. As the water-cooled mold heats up, molten copper solidifies and is simultaneously withdrawn from the cooled mold and submerged container. The process leads to the formation of copper rods that are further processed by drawing, rolling, or extruding to obtain the desired shape.

The Tundish-free Casting Rolling Copper Rod Machine is a newly developed continuous copper rod casting machine. The modern machine combines casting with rolling in a single step without tundish (a kind of refractory container that is used as a feeder for steel casting molds). It also has high production efficiency due to rapid cooling and solidification of copper alloy under the effect of low-temperature liquid nitrogen.

Specification and Maintenance

• Material: Copper wire rod continuous casting machines are made of copper alloy. The alloying elements affect its mechanical properties, thermal conductivity, abrasion resistance, and corrosion resistance.
• Structure: It usually includes a melting unit, a pouring unit, a cooling unit, a conveying unit, and a cutting unit, among other parts. The specific names and functions of some units may vary according to different manufacturers.
  The melting unit is responsible for melting the copper or copper alloy, transforming it into liquid copper, and feeding it to the pouring unit. The pouring unit is responsible for uniformly pouring the liquid copper into the cooling unit for solidification and continuous casting. The cooling unit is responsible for cooling and solidifying the liquid copper, which is often achieved through a water cooling system. The conveying unit is responsible for conveying the continuously cast copper to the cutting unit, which is responsible for cutting the copper wire rods into required lengths.
• Capacity: The processing capacity of a continuous casting machine typically ranges from several tons to over ten tons per hour, depending on the type.

Copper wire rod continuous casting machines have complex structures and precise parts, so they require regular maintenance. The following is a detailed maintenance plan:

• Regular Inspection:Develop a regular inspection schedule and ensure it is carried out. During the inspection, check all parts to observe if there are any signs of wear, damage, or looseness. Pay particular attention to key components like transmission systems and cooling systems.
• Lubrication Maintenance:Lubricate each moving part according to the equipment manual and ensure the lubricant is clean and free of impurities. Regularly replace lubricants and thoroughly clean the parts prior to lubrication.
• Cooling System Maintenance:Check the water flow rate and temperature of the cooling system to ensure it remains within the appropriate range. Regularly inspect water pipes and cooling devices for leaks or blockages, and clean them promptly as necessary.
• Electrical System Maintenance:Clean the electrical components and connections, removing dust and dirt. Check the electrical circuits for signs of wear or damage, and repair or replace them as needed.
• Hydraulic System Maintenance:Check the oil level and oil quality of the hydraulic system, ensuring it is within the specified range and free of contaminants. Inspect hydraulic pipes for leaks or damage, and tighten them as needed.
• Dust and Debris Removal:Regularly remove dust and debris from the surfaces of critical components and radiators to ensure adequate equipment cooling and prevent overheating.
• Operating Procedures:Ensure operators are familiar with the equipment manual and operating procedures to avoid improper operations that could lead to equipment damage.
