Introduce the production process of customized Dalian special steel

The production of customized Dalian special steel is a precise journey intertwined with technology and craftsmanship, and every process is filled with a persistent pursuit of good quality.

At the beginning, in-depth demand research kicked off. A professional team interacts closely with clients and comprehensively analyzes industry characteristics. If special steel is required for automobile engine manufacturing, the strength retention and fatigue resistance under high temperature and high pressure must be considered; For deep-sea exploration equipment, corrosion resistance and pressure resistance have become key indicators. After accurately anchoring these requirements, the formula design has direction, and researchers carefully mix the proportion of alloy elements based on this, like a "secret recipe" for a precise chemical reaction.

The preparation of raw materials follows closely behind, which is the cornerstone step. According to the formula, high-purity iron ore, rare metals and other raw materials are carefully selected from all over the world, and the impurity content is strictly controlled. Even the slightest deviation may affect the performance of the finished product. Only high-quality and adaptable raw materials can enter the subsequent rigorous manufacturing process.

The raw materials in the smelting process are accurately proportioned and fed into the electric furnace or converter, where they are transformed into red molten steel at high temperatures. During the process, the temperature is precisely controlled to Celsius degrees, and the atmosphere is meticulously regulated to ensure that various alloy elements are fully and uniformly fused. Impurities are further removed through refining techniques such as vacuum degassing and external refining.

In the forming stage, relying on continuous casting or mold casting processes, liquid steel is shaped into various shapes according to customer needs, from large forging steel ingots to fine pipes, with dimensional deviations controlled within a very small range.

The subsequent heat treatment process involves precise control of heating, insulation, and cooling rates to optimize the internal crystal structure of the steel and improve its hardness, toughness, and other properties. After going through multiple quality inspection stages such as fine flaw detection and mechanical performance testing, only customized Dalian special steel that fully meets the standards can flow into the market, injecting strong power into the exclusive industrial field and achieving industrial legends.
