Part 1: Melting Room

The melting room of Taeantech high vacuum continuous casting machines is a vital part of the equipment, which is responsible for efficiently and evenly heating the metal raw material to a molten state, providing high-quality molten metal for the subsequent casting process. 

Frequency conversion heating: The melting room combined with IGBT frequency conversion technology can achieve precise adjustment of heating power to ensure temperature stability and uniformity during the melting process. Automatic frequency tracking, making the melting process more stable and safer. Operate without noise. Electromagnetic stirring function to reduce segregation of molten metal. Shrinkage porosity and porosity in castings are significantly reduced, and the appearance of castings is smoother.

PID±1°C Temperature Control: PIDs are used to precisely control the temperature inside the melting furnace to ensure that the metal melts within the optimal temperature range while avoiding overheating and affecting the quality of the metal product. PID temperature control system has the characteristics of accurate control, fast response, elimination of deviation accumulation, prediction and reduction of fluctuations, adjustable parameters, intelligence, automation, etc., as well as high reliability and stability. Together, these characteristics constitute the superior performance and wide application value of the system in the field of precious metal continuous casting.

Inert gas protection: Inert gases (such as nitrogen, argon, etc.) can effectively isolate oxygen and prevent metal oxidation due to their non-reactive chemical properties. It also allows for precise control of the atmosphere in the melting room and avoids interference from other impurity gases. This control is essential to ensure the stability and repeatability of the metal melting and continuous casting process. Under the protection of inert gases, the porosity generated during metal melting and continuous casting is greatly reduced.

The melting room of Taeantech High Vacuum Continuous Casting Machine plays an irreplaceable role in the continuous casting process of precious metals. Its efficient melting capacity, guaranteed metal purity, maximum resource utilization, safety and reliability, and improved product quality provide strong support for the precious metal processing industry.

Part 2 Casting Chamber

The casting room of the Taeantech high vacuum continuous casting machine is one of its key components, which is responsible for casting the molten metal in the melting room into the desired shape and size under a high degree of vacuum protection.

High vacuum protection: casting in a high vacuum state can effectively prevent porosity and inclusions in the casting, and the high vacuum environment can ensure the compactness and purity of the casting, thereby improving the overall quality of the casting. This is especially important for the manufacture of high-end metal raw materials such as bonding wire. In the vacuum state, the contact of the molten metal with oxygen is greatly reduced, which reduces the risk of metal oxidation and guarantees the surface finish and intrinsic quality of the casting. Due to the reduction of porosity, inclusions and oxidation, the quality of the casting is improved, which in turn reduces the scrap rate and subsequent processing costs.

Crystallizer: The crystallizer is located at the heart of the casting room and is the key to the solidification and crystallizering of molten metal. Taeantech crystallizers are manufactured with copper-based alloys that have good thermal conductivity and wear resistance. Taeantech precision continuous casting machines use down-lead casting technology where molten metal flows continuously into the crystallizer through a sprue. In the crystallizer, the molten metal is rapidly cooled and solidified into a shell, which is then continuously drawn out by a pilot rod or blank drawing device to form the desired casting shape. By controlling parameters such as pouring speed, cooling intensity, etc., the size and performance of the casting can be precisely controlled.

Guide wheel: guide wheel is located below the crystallizer. After the thick metal wire pulled out by the upper guide rod is squeezed and thinned, the guide wheel will rotate rapidly to pull the metal wire into circles of soft thin metal wire. Due to the clever spacing design and soft material of the guide wheel, the produced metal wire will not be defective, the produced metal wire is of good quality, and the production efficiency of the metal wire is extremely high. 

Cooling System: Taeantech cooling system is designed with materials and structures with high thermal conductivity to quickly remove heat from castings and molds, enabling rapid cooling and solidification of castings. By optimizing the distribution and flow of the cooling medium, it ensures that the casting is heated evenly during the cooling process, avoiding thermal stress and cracks caused by excessive temperature gradients. The cooling system can provide a variety of cooling mode options, such as spray cooling, water curtain cooling, etc., according to the needs of different metal materials and casting processes, to meet the cooling needs of different castings.

The casting room of Taeantech high vacuum continuous casting machine has been widely used and promoted in the metal materials industry due to its advantages of high quality, high efficiency, automation, safety and wide adaptability.

Part 3 Intelligent Control Systems

The intelligent operating system of Taeantech high vacuum continuous casting machine mainly embodies the characteristics of automation, digitalization, intelligence, and safety, and is an important intelligent brain in the process of metal continuous casting. 

Mitsubishi PLC: Taeantech high vacuum continuous casting machine adopts advanced brand Mitsubishi PLC (Programmable Logic Controller) control system, which has a high degree of accuracy and stability, and can realize automatic control of the production process. Through the Mitsubishi PLC control system, users can easily set production parameters such as temperature, pressure, time, etc., to ensure that the equipment operates accurately according to the set program.

Dual human-machine intelligent interface: Taeantech high vacuum continuous casting robot has two intelligent interfaces. (upper and below) With a simple UI (user interface) design, the concise interface layout helps reduce misoperation and improve production efficiency. The dual interfaces are highly intelligent. The upper interface allows the operator to easily adjust the machine's operating parameters through an intuitive touch screen or button, and the entire metal continuous casting process can be completed with just one click of a button. The below interface can display and adjust the cooling water inlet temperature and crystallization temperature. The dual intelligent operation interface ensures flexible operation while making the machine run most efficiently. Compared with traditional segmented continuous casting that requires a lot of manpower, Taeantech high vacuum continuous casting machine saves time, effort and is extremely efficient.

Safety protection: stable system, perfect electrical system protection function, highly intelligent fuselage self-test alarm system and multiple protection technology. Such as overload protection, short circuit protection, leakage protection, etc., when the equipment is abnormal, it can cut off the power supply in time and send out an alarm signal. At the same time, the system is equipped with emergency stop buttons, protective covers and other safety devices to deal with emergencies and prevent operators from being injured. 

The intelligent operating system of Taeantech high vacuum continuous casting machine realizes accurate data control and efficient management in the metal continuous casting process through PLC control, concise UI interface and safety protection functions, and improves production efficiency and metal continuous casting product quality.
