Description

Technical Field

[0001] This utility model relates to the field of heat treatment technology for hot-rolled steel, and in particular to a high-efficiency multi-channel heat treatment device for hot-rolled steel. Background Technology

[0002] Hot-rolled steel is steel produced by rolling steel billets after heating them at high temperatures. The heated billets have good plasticity and ductility. Under the pressure of the rolling equipment, they undergo plastic deformation and eventually form the required plates, profiles, or pipes. This processing method does not require complex cooling or subsequent strengthening treatments, and can retain the steel's good toughness, plasticity, and weldability. Moreover, the production process is simple and the cost is relatively low. It is widely used in fields such as building structures, machinery manufacturing, and pipeline laying, where there are basic requirements for material strength and processing adaptability. It is a widely used basic steel type in industrial production.

[0003] Heat treatment of hot-rolled steel is a subsequent processing technique that adjusts the internal microstructure of the steel through controlled heating, holding, and cooling operations. This process does not rely on intelligent control; it optimizes material properties solely through physical temperature changes. It can improve the strength, hardness, toughness, or wear resistance of hot-rolled steel, eliminate internal stresses generated during rolling, and enhance the dimensional stability and processing adaptability of the steel. It is widely used in machinery manufacturing, construction engineering, and other fields, providing steel products with precisely matched performance for different applications.

[0004] Traditional single-channel heating furnaces suffer from limited internal space layout and a single material heating path, resulting in limited processing capacity per unit time, low production efficiency, easy heat loss along the channel and difficulty in centralized utilization, leading to energy waste. At the same time, the heat distribution is affected by the channel structure and cannot evenly cover the material, which easily causes local temperature differences and affects the heating effect.

[0005] Therefore, it is necessary to provide a high-efficiency multi-channel heat treatment apparatus for hot-rolled steel to solve the above-mentioned technical problems. Utility Model Content
