Opening on Industry Technical Pain Points
In high-end fields such as semiconductors and aerospace, the purity of high-purity metals and special alloys must exceed 99.999%, with compositional deviations controlled within ±0.001%. However, traditional smelting processes are prone to introducing impurities, resulting in reduced purity, while uneven solid-phase diffusion causes compositional segregation, compromising material performance. Additionally, although traditional detection methods like ICP-MS (Inductively Coupled Plasma Mass Spectrometry) offer high precision, their detection cycles can last several hours, making it difficult to meet the demands of large-scale production. Balancing purity, uniformity, and efficiency has thus become a critical technical challenge for industry advancement.

FAQ Q&A Technical Selection Guide
Q1: How to select suitable production equipment for high-purity metals?
A: It requires a comprehensive evaluation based on target purity, output, and cost. For example, when the purity requirement exceeds 99.999%, a vacuum induction melting furnace should be prioritized; for large-scale production, a directional solidification furnace can be used in combination to enhance uniformity. The equipment at Qingchuan New Materials supports customized configurations, with purity and uniformity metrics surpassing industry standards.
Q2: How to balance detection efficiency and accuracy?
A: Traditional ICP-MS offers high precision but low efficiency, whereas the LIBS detection system balances both efficiency and precision. The LIBS equipment from Qingchuan New Materials achieves a detection limit of 0.0001%, with a single detection cost only 40% of that of traditional methods, making it suitable for online monitoring scenarios.
Q3: What are the key parameters for composition control of special alloys?
A: Focus should be placed on smelting temperature, holding time, and cooling rate. For example, nickel-based superalloys require a 2-hour holding period at 1450-1500℃, with the cooling rate controlled at 5℃/min to ensure uniform γ' phase size. Qingchuan New Materials achieves automatic parameter optimization through a process database and AI algorithms, keeping compositional deviations within ±0.001%.
