copper mould tube
Main product: Square/Round /Rectangle Copper tubes
With dedicated to research of new technologies, we continuously developed various sizes,materials and special shapes, large and super large size mould tubes. We also developed various types of high efficiency copper mould tube for continuous casting machine. Our products range also features mould assembly and other metallurgical spare parts. Apart from copper mould tubes, we also produce various types of copper mould plates and assembled beam blank moulds.
Copper mould tubes are mainly used in the process of continuous metal casting as molds for cooling and solidifying liquid metal. During the casting process, liquid metal is injected into the crystallizer tube and cooled and solidified along the tube wall to eventually form a casting of the desired shape. Due to its excellent thermal conductivity, corrosion resistance and electrical properties, copper crystallizer tubes are widely used in the field of metal casting.
Material and characteristics
Material: Copper mould tubes are mainly made of copper or copper alloys. Copper, as a metal element, has good electrical conductivity, thermal conductivity and ductility, which enable copper crystallizer tubes to perform excellently in the metal casting process.
Characteristics:
Excellent thermal conductivity: Copper crystallizer tubes can quickly transfer the heat of liquid metal to ensure that the casting can be cooled and solidified evenly and quickly.
Corrosion resistance: Copper crystallizer tubes can still maintain good performance and service life in harsh environments, which is of great significance for ensuring the quality of castings and extending the service life of equipment.
Electrical performance: Copper crystallizer tubes also have good electrical properties, which makes it also have potential application value in some specific electrical applications.
Production process and coating
Production process: The production process of copper crystallizer tubes usually includes casting, processing, heat treatment and other links. Among them, the casting link is one of the key steps to ensure that the copper crystallizer tube has excellent performance. Through the precise casting process, the copper crystallizer tube can be ensured to have the required shape and dimensional accuracy.
Coating: In order to improve the service life and wear resistance of the copper crystallizer tube, a coating with suitable hardness is usually applied to its surface. Common coating materials include hard chromium, nickel-chromium alloy, etc. These coating materials can significantly improve the wear resistance and corrosion resistance of the copper crystallizer tube, thereby extending its service life.
Application field
Copper crystallizer tubes have a wide range of applications in the field of metal casting, especially in the continuous casting process. It is widely used in the production of castings of various shapes, such as steel pipes, copper pipes, aluminum pipes, etc. In addition, copper crystallizer tubes can also be used to manufacture other metal products, such as automotive parts, mechanical equipment parts, etc.
As the old saying goes, one must sharpen his tool before going to make a perfect work, our company spends heavily on the manufacturing equipment of copper mould tubes and plates. Now we have 9 sets of large, medium and small hydraulic press, 30 sets of CNC machine centers, 2 sets special CNC processing machines, We have complete electroplating facilities, first class electro-plating equipment and up-to-date electro-plating technologies. We have two electro-plating workshops for mould tube plating and mould plates plating separately and each of them covers an area of 1800 square meters. There are 32 tanks for Cr plating of mould tubes and 7 tanks for plating of mould plates. The maximum siza of round tubes that can be plated is up to Dia.1500mm and the widest mould plates can be plated is up to 3800mm. We have advanced watertreatment system. We adhere strictly to the environmental policy of zero emission which makes our company a green and environment-preserving enterprise.
TP2 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 is adding 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 heatresistant property than TP2.
Cu-Cr-Zr is a kind of copper allys 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.
Copper has lower hardness which leads to lower anti-abrasive property. Therefore, the area at the lower part of the moulds, where the stress increases drastically due to shells, will be more severelyworn. To increase the life time of copper moulds, LMM provides uniform mould interior surface plating with suitable hardness. Most of the copper mould tubes for small size billet casting are not used in any casting system where there are rigid casting stream support, therefore they are very sensitive to be worn. We use hard chrome plating to increase the life of mould tubes. The plating thickness recommended by LMM will be controlled in the best range. As for the coating of copper mould plates, based on our years of experience, we are able to provide Cr coating, Ni-Cr coating, Ni-Fe coating and NiCo-Cr coating to meet the demand of various customers both at home and abroad.
Our company has 50 technicians and 15 of them have senior professional titles. We have strong ability to develop products of various materials and sizes (Square, Rectangular, Round, Nonstandard and Beam Blanks, with range from the smallest of 50x50mm to the largest of Dia.1500mm round tubes, 500x500mm Square tubes, 120×650 rectangular tubes). Strong R&D abilities can meet the customers demand to the maximum extent. The perfect combination of experience and theories constantly improves the quality of our products. We are dedicated to shaping steel!
We not only provide products, we also provide handicrafts, the mirror finished tubes surface is like a mirror.
