Product Introduction of Copper Mould Tube:

Our main products are square, Rectangular, Round, and Beam Blank copper mold tubes. We are dedicated to researching new technologies and continuously developing various sizes, materials, and special shapes, as well as large and super-large size mold tubes. We have also developed various types of high-efficiency copper mold tubes for continuous casting machines. Our product range also features mould assembly and other metallurgical spare parts.

Raw Material of Copper Mould Tubes

To meet our customers’ exact requirements, we deliver mould tubes crafted from premium materials, each selected for optimal physical and mechanical performance. Our mould tubes are available in the following materials:

P2 is a kind of material is selected by most of the steel plants.It shows excellent heat-proof and anti- fatigue property under high temperature and it has good processing property.

CuAg0.1 with 0.08%-0.12% silver during copper ingots melting will increase the recrystallization temperature of copper by 100C, which will increase the heat stress and anti-abrasive property of copper mould tube interior surface, showing better heat resistant property than TP2.

Cu-Cr-Zr is a kind of copper alloys which can be normalized by time.It has excellent mechanical property under both room temperature and hight temperature. It has hight heat conductivity, melting point, anti-fatigue and anti heat stress properties. Their outstanding features make it different from the previous copper alloys. It combines all good properties together. But compared with other copper alloys, Cu-Cr-Zr is difficult to be formed with higher products costs.

Taper

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.

Coating

Copper has relatively low hardness, resulting in limited wear resistance. This makes the lower part of the mould—where stress increases significantly due to the formation of solid shells—especially prone to wear. To extend the service life of copper moulds, CYKC GROUP offers precision interior surface plating with optimized hardness for enhanced durability.

For small-size billet casting, most copper mould tubes operate without rigid casting stream support, making them particularly susceptible to abrasion. To address this, we apply hard chrome plating, effectively improving the wear resistance and service life of the mould tubes. The plating thickness is strictly controlled within the optimal range recommended by CYKC GROUP.

As for mould tubes, we also provide advanced coating solutions for copper mould plates, leveraging our extensive industry experience. Available coatings include Cr (chromium), Ni-Cr (nickel-chromium), Ni-Fe (nickel-iron), and Ni Co-Cr (nickel-cobalt-chromium), tailored to meet the specific needs of customers both domestically and internationally.

Continuous casting machine

Copper mould tubes are a key component in any continuous casting machine. They play a vital role in quickly solidifying molten steel into billets during the casting process. Positioned at the core of the continuous caster, copper moulds must offer excellent thermal conductivity and high mechanical strength.

When molten metal is tapped from the furnace, it first flows into a ladle. From there, it’s directed through a refractory shroud into a tundish. The steel then moves from the tundish into an open-base copper mould through another shroud. As it passes through the copper tube, the liquid steel solidifies into billets with the desired shape.

Due to this crucial function, the quality of copper moulds is extremely important. Our mould tubes meet high standards to ensure reliable performance and casting precision.
