Continuous casting rolling copper

Types of Continuous Casting and Rolling Copper

Continuous casting rolling copper refers to a method of manufacturing copper alloys through sequential casting and rolling processes. Various types of machines are available that can manufacture copper through continuous casting and rolling or other methods.

• Continuous casting rolling mills:

  These are integrated mills that combine both continuous casting and rolling processes into a single unit. It's a large-scale industrial facility that streamlines the production of materials like copper by eliminating the need for separate machines for casting and rolling. Continuous casting rolling mills simplify the production flow, making it more efficient. Using one machine for both continuous casting and rolling can improve productivity and reduce costs compared to using different machines for each process. It also takes up less space in the factory. The mill produces copper strips or sheets directly.

• Independent casting units with rolling mills:

  This setup includes separate machines for continuously casting copper and rolling it into desired shapes. Independent casting units are responsible for pouring molten copper into molds to create solid pieces. These independent units are then linked to rolling mills that shape the cast copper into sheets, strips, or other forms. The rolling mills flatten and profile the copper material created by the independent casting units. While continuous casting units and rolling mills are distinct machines, they are often closely integrated. The casting units supply the raw material, and the rolling mills shape it further for various applications. Despite being separate machines, the two processes work together closely to efficiently produce shaped copper materials.

• Continuous casting machines:

  These are specialized devices used to produce copper alloys by continuously casting them into various shapes, such as billets, blocks, slabs, and ingots. In contrast to other casting methods, continuous casting offers better control over the material's properties and enhances productivity. The process typically involves melting the metal, pouring it into a mold, cooling it, and extracting the solidified cast continuously. Continuous casting machines for copper may come in different configurations depending on the specific alloy being produced and the shape of the cast that is desired.

• Rolling mills:

  These are machines that are used to shape metal by passing it through rolls. The process of rolling involves reducing the thickness of the metal, and in the case of copper, it results in the production of sheets, plates, strips, and foils made of copper or copper alloys. Non-ferrous rolling mills are usually employed to work with copper and other non-ferrous metals. Depending on the final product requirements, rolling mills for copper can vary in size, capacity, and technology. They may be:

  • Flat rolling mills: These are typically used to produce thin sheets and plates.
  • Cold rolling mills: These are used for rolling operations that are conducted at temperatures below the recrystallization temperature of the metal, resulting in a harder, stronger material with a superior surface finish.
  • Cross rolling mills: These are rolling mills in which the rolling direction is transverse to the metal flow direction, applied to non-ferrous metals and alloys.
  • Hot rolling mills:These are used to process metals at high temperatures, making them easier to shape and form. Rolls are giant heavy cylinders that are used to shape the metal into thin sheets or plates by pressing and squeezing the metal between them. The material is often heated before it is put between the rolls. In contrast to cold rolling, hot rolling increases ductility and reduces yield strength.
  • Universal rolling mills:These are versatile rolling machines that can perform various rolling processes, including flat, edge, and groove rolling universally.

Specifications and maintenance of continuous casting rolling copper

Specifications

Some key specifications related to the continuous casting copper process are as follows:

• Copper shapes: Continuous copper casting generally creates particular shapes, such as billets, ingots, bars, and slabs.
• Casting speed: This speed refers to the rate at which copper alloys are solidified and removed from the casting machine. In general, the casting speed (mm/min) varies depending on machine types, process parameters, and specific materials.
• Cooling methods: Continuous casting copper can use different cooling methods to solidify molten metal. Water cooling, air cooling, and spray cooling are typical. The cooling method also affects the casting speed and quality.
• Casting machine: Continuous casting machines for copper alloys can be classified into different types, such as the vertical (or upcasting), horizontal, and continuous casting and rolling methods. Each machine has its characteristics, advantages, and applicable areas.
• Material: Continuous casting copper is usually made from copper alloy. Its composition and properties may vary depending on the use requirements.
• Production efficiency: Continuous casting copper can improve production efficiency compared to traditional casting methods. It reduces the process of heating, melting, pouring, and cooling, thus shortening the production cycle.

Maintenance

The continuous copper casting machine must be regularly maintained for routine inspections and repairs to ensure its proper operation. The following are some general maintenance methods:

• Regular inspections: Scheduled inspections should be performed, such as weekly, monthly, quarterly, etc., to check various parts' status, such as electrical systems, cooling systems, and feeding mechanisms. Look for signs of wear, looseness, damage, etc., and promptly address any issues that may arise.
• Lubrication and maintenance: Continuously cast lubricate and maintain key parts, such as gears, bearings, etc., in accordance with the machine's manual. Ensure that the lubrication is suitable, ensuring the equipment runs smoothly.
• Replacement of wearing parts: Continuously cast wearing parts, such as molds, conveying belts and cooling pipes, need to be regularly replaced to ensure the stability of the casting process and the quality of the products.
• Cleaning: Regularly clean continuously cast molds, cooling systems, and conveying devices to remove residues, oxides, and impurities. Cleaning can prevent clogging and ensure smooth material flow and heat transfer.
• Electrical system maintenance: Regularly check and maintain the electrical systems, such as checking wires, connectors, and control devices, ensuring that the electric systems are in good condition and the electrical safety is ensured.
• Cooling system maintenance: Regularly check the working status of the cooling systems, such as water flow, water pressure, and cooling effect, ensuring that the equipment has effective cooling capacity.
• Keeping the working environment clean: The working environment should be kept clean, removing dust, debris, and impurities, thus preventing them from entering the continuously casting equipment and affecting its operation and product quality.
• Operating standardization: During the use of the equipment, the operating standardization is ensured, following the operating procedures, and avoiding improper operations that may damage the equipment.
