In the modern industry that pursues ultimate performance, the continuous castability of metal materials directly determines the ceiling of the final product. The traditional continuous casting method is carried out in an atmospheric environment, and problems such as incomplete and intermittent metal products are difficult to avoid, which has become a bottleneck restricting the development of high-end metal materials.
So, is there a technology that can fundamentally eliminate these defects like casting metal in a ‘space environment’? The answer is yes – vacuum continuous casting machine. And the application field of vacuum continuous casting machine is very wide
What is vacuum continuous casting?
Simply put, vacuum continuous casting is an advanced process that continuously injects molten metal into a crystallizer and continuously pulls out the casting billet in a highly vacuum environment. It combines the two major advantages of “vacuum degassing” and “continuous molding” into one:
Vacuum environment: completely eliminates the reaction between molten metal and gases such as oxygen, nitrogen, and hydrogen, greatly reducing porosity and oxide inclusions, and improving the purity, density, and mechanical properties of the metal.
Continuous forming: It achieves uninterrupted production from liquid metal to solid castings, with high efficiency and automation, and can also obtain infinitely long castings with uniform structure and excellent surface quality.
Disrupting which industries? The Wide Application Field of Vacuum Continuous Casting Machine
The application of this’ artifact ‘goes far beyond the traditional steel field, it is injecting new vitality into a series of high-end manufacturing industries.
1. Special alloys and aerospace
Application: This is the core battlefield of vacuum continuous casting machines. Used for casting materials with extremely high purity requirements such as high-temperature alloys, titanium alloys, and precision alloys. These materials are crucial for manufacturing aircraft engine blades, rocket engine components, and spacecraft structural parts.
Value: The extremely high fatigue strength and high-temperature stability ensure the safety and reliability of the aircraft in extreme environments.
2. High end medical implants
Application: Used for producing biocompatible metal billets such as medical titanium alloys (such as Ti-6Al-4V) and cobalt chromium alloys.
Value: The cast billet is pure and free of impurities, avoiding corrosion or allergic reactions of implants in the human body. At the same time, its excellent mechanical properties are more compatible with human bones, making it an ideal choice for manufacturing artificial joints, dental implants, and bone plate screws.
3. Semiconductors and Electronic Information
Application: Production of high-end conductor materials such as oxygen free copper, high-purity copper, and phosphorus deoxidized copper. These materials are the basis for manufacturing semiconductor silicon single crystal growth furnace crucibles, lead frames, and sputtering targets.
Value: The extremely low oxygen content and high conductivity ensure the stability of the thermal field and the efficiency of current transmission during the chip manufacturing process, directly affecting the performance and yield of the chip.
4. Research and development of new materials
Application: Major research institutes and material laboratories use small vacuum continuous casting machines to develop new alloy formulas, study solidification processes, and conduct small-scale trial production.
Value: Provided a key “first step” preparation method for new materials from the laboratory to industrialization, accelerating the emergence of new materials.
Can everything be cast? What models can vacuum continuous casting machine make?
The “model” of a vacuum continuous casting machine does not refer to toys or figurines, but rather to the primary product form directly produced by it, that is, the billet for subsequent deep processing. According to the shape and drawing method of the crystallizer, it can produce a variety of “models”:
1. Rod/Round Ingot
Description: This is the most common form, with a circular cross-section.
Subsequent processing: It can be further processed into shaft parts, turbine discs, bar products, etc. through forging, rolling, turning, and other methods.
2. Square billet/flat ingot
Description: The cross-section is square or rectangular.
Subsequent processing: mainly used for rolling into plates, strips, and foils, it is the substrate for aerospace skins, medical boards, and electronic components.
3. Pipe billet
Description: Hollow tubular billets are directly drawn and cast through specially designed crystallizers.
Subsequent processing: It can be used for subsequent cold rolling and cold drawing to produce precision seamless pipes, which are applied in fields such as medical devices (such as vascular stent blanks), nuclear industry, and special fluid transportation.
4. Customized profiles
Description: Customize crystallizers with specific cross-sectional shapes according to customer needs, in order to cast billets that are close to the final product shape in one go.
Subsequent processing: This greatly reduces the amount of subsequent mechanical processing, saves material costs, and is suitable for mass production of products with specific cross-sections, such as profiles, guide rail blanks, etc.
Vacuum continuous casting machine is no longer an unattainable expensive equipment, but one of the core equipment driving the upgrading of high-end manufacturing industry. It protects the purity of metals with “vacuum” and defines efficient production with “continuity”. In today’s pursuit of ultimate material performance, choosing vacuum continuous casting technology means choosing more reliable quality, superior performance, and a more competitive future.
When others are still troubled by material defects, you can already create your own technological barrier in one go.
