At present, the mechanical design of ZCuPb17Sn4Zn4 cast lead bronze in China is still in a relatively weak position, and it lags far behind in terms of development. Therefore, China still needs to change its current design concept, learn from foreign design theories and technologies, innovate in technology, and add value to products through aesthetic design in order to stand among the strong players. That is to say, mechanical design needs to develop with the times, and the theory of mechanical design needs to be combined with new design theories and innovated. 1.2 Business Design is an emerging interdisciplinary field that integrates knowledge from multiple disciplines. Therefore, business design is not only about designing products, but also requires the integration of people, machines, and space, science and technology. It is highly comprehensive and involves a wide range of disciplines, including biology, physics, aesthetics, psychology, sociology, engineering, marketing, and ergonomics. In 2006, the Board of Directors of the Industrial Design Association defined industrial design as follows: "Design is a creative activity aimed at establishing multiple qualities for objects and their entire lifecycle. Experiments have shown that the nitriding cycle using this process is shortened by 1/3 to 1/2 compared to the process cycle. The nitriding speed is significant. In 1985, the predecessor of SSiemag company, Westmark AG, successfully cast a 50mm thin slab at its experimental plant in Kreuztal Busch ü tten. The core of this technology is the funnel-shaped crystallizer and the immersion water nozzle technology. The other parts also include a vertical bend section, which is easy to use. The production process of typical ultra di carbon and ultra di nitrogen steel in contemporary converters is mainly divided into two types: process and double process. Rolling regulations and settings 3. Terminology related to heat treatment of steel: "Dual process" smelting of super di carbon and super di nitrogen steel, with an average carbon content of 0.034% at the smelting endpoint, 0.0015% at the vacuum refining endpoint, 0.0016% at the intermediate ladle, and 1 × 10-6 carbon increase from vacuum to intermediate ladle, with a carbon increase rate of 6.7%.
