Casting problems? Looking to increase production? Solve quality issues? LMMGROUP offers custom copper mold tubes that are designed based on your specific needs.
The role of mold copper tube：
In the process of steelmaking and continuous casting of steel companies, molten steel must first pass through the crystallizer copper tube to exothermic cooling and solidification at a certain speed before it can change from liquid to solid.
What are the characteristics of copper tube mould？
The copper tube mold must have the characteristics of wear resistance, high temperature resistance, corrosion resistance, high strength, high hardness, and good heat dissipation.
What are the raw materials of the crystallizer copper tube?
To provide mould tubes with optimal physical and mechanical properties to customers’ specifications, mould tube products are supplied of the following materials:
- Cu-DHP: Normally used for mould tubes section size below 180x180mm and round tubes below Dia.150mm.
- Cu-Ag: Normally used for mould tube section size above 180x180mm and round tubes above Dia.150mm
- Cu-Cr-Zr: Normally used for beam blank mould tubes
These materials have different levels of hardness and thermal conductivities. We are highly experienced in choosing proper materials to meet the specific demands in heat resistance and thermal conductivities of customers’ applications. The physical and mechanical properties of these materials are compared in details in the following tables:
| High Phosphorus Deoxidized Copper | Normal deoxidized copper. |
| Silver-Bearing Copper | Through the addition of about 0.1% silver, strength is significantly enhanced with no loss in thermal conductivity. Compared to deoxidized copper, the softening temperature is also about 100 degrees Centigrade higher than deoxidized copper |
| Cu-Cr-Zr | Cr and Zr precipitation hardening provides this alloy with high strength, high resistance to heat, and thermal conductivity as high as high-phosphorus deoxidized copper. |
| Material | Cu-DHP | Cu-Ag | Cu-Cr-Zr |
| Melting point | 1083℃ | 1083℃ | 1078℃ |
| Coefficient of thermal expansion at 20℃ | 1.68×10-5 | 1.68×10-5 | 1.70×10-5 |
| Thermal | 340 W/(m·K) | 377 W/(m·K) | 325 W/(m·K) |
| Recrystallization | 330℃ | 370℃ | 700℃ |
| Hardness at 20℃ | Min. 85 HB | Min. 90HB | Min. 120HB |
Taper exactly to your specifications:
The Taper of Copper Moulds is of vital importance to the performance and life.
We supply Copper Moulds of best suitable tapers and stronger anti-wearing plating for copper mould tubes and mould plates.
Ranging from Single Taper, Double Taper, Triple Taper to Multiple Taper we supply all variants.
Each mould taper is tested by the computer-operated taper monitor and the taper graph for each mould tube is delivered along with mould tubes.
Nevertheless, the mold also has a service life, reaching a certain amount of steel, and the inner layer must be replaced after wear.
Although there are some companies that repair and rebuild or trade in copper pipes that are replaced during use, they are all repairs in the traditional sense, and they are plated with the original metal material – hard chrome. It has no practical significance to completely change the performance of copper pipes, increase the amount of steel passing through, and reduce costs.
