Copper mould tubes are an essential component of steel casting machines. These tubes are widely used in the formation of continuous steel billets and slabs. They provide a crucial function of shaping and cooling the molten steel as it solidifies into a long, continuous strand.
Manufacturing copper mould tubes is a highly specialized process that requires great precision and attention to detail. Let's take a look at the various steps involved in the manufacturing of copper mould tubes.
Selection of Raw Materials
For the manufacturing of copper mould tubes, high-quality raw materials are essential. These materials are selected based on their chemical composition and physical properties that are suitable for the production process.
The primary material used in the manufacture of copper mould tubes is pure copper. Other materials such as chromium and zirconium are added to enhance the tube's properties such as hardness, thermal conductivity, and corrosion resistance. These elements are selected based on their ability to withstand high temperatures and resistance to chemical erosion.
Mould Preparation
The mould preparation process involves shaping the copper material into a tube with a specific internal diameter and taper angle. This process is carried out using high-precision machinery such as lathes and grinding machines. The mould taper also needs to be carefully calculated based on the type of steel being cast and the casting machine requirements.
Coating Application
Copper mould tubes require a special coating to protect them from the corrosive effects of molten steel. The coating also helps to improve the tube's release properties while making it easy for the solidified steel to be removed. The coating is a special chromium alloy that is sprayed onto the mould surface using a high-velocity flame. There are various types of coating materials available, and the choice of coating depends on the steel quality and the casting machine.
Quality Control
Throughout the manufacturing process, quality control measures are implemented to ensure that the copper mould tubes meet the required specifications. The tubes are checked for their dimensions, taper angles, coating thickness, and other properties to ensure that they are of the highest quality.
Final Inspection and Packaging
Once the copper mould tubes are manufactured, they undergo a final inspection process to certify their quality. All tubes are packed in specially designed wooden crates to protect them during transit. They are also marked with identification tags carrying information such as the tube dimensions, coating type, and date of manufacture.
In conclusion, the manufacturing process for copper mould tubes is a complex and highly specialized one that requires great precision and attention to detail. The use of high-quality raw materials and modern machinery, coupled with stringent quality control measures, ensures that the end product meets the required specifications.
