Embodiment Construction

[0025] The present invention applies the process of thin slab continuous casting and rolling to produce Ti microalloyed high-strength weather-resistant steel plate. According to the characteristics of thin slab continuous casting and rolling process and the metallurgical composition of molten steel, electric furnace or converter is used for smelting, refining, thin slab continuous casting, casting After the slab is solidified, it directly enters the process flow of roller hearth heating or soaking furnace, hot rolling, laminar cooling, and coiling. The temperature of the thin slab entering the furnace is 900-1100°C, the temperature of exiting the furnace is 1050-1180°C, and the temperature of final rolling is 850-850°C. 910℃, after laminar cooling, the coiling temperature is 550~650℃, the metallurgical composition range of molten steel is: C: 0.04~0.07wt%; Si: 0.3~0.5wt%; Mn: 0.4~1.2wt%; P: 0.075 ~0.10wt%; S: ≤0.005wt%; Cu: 0.20~0.40wt%; Ni: 0.15~0.35wt%; Ti: 0.02~0.15wt%; Cr: ...

Abstract

A conticasting and tandem rolling technology for manufacturing the high-strength and-weatherability Ti-microalloyed steel plate includes such steps as smelting, refining, conticasting, solidifying, heating, hot rolling, laminar flow cooling and coiling. Its advantages are high strength, high shaping performance, high weatherability and high weldability.

Description

technical field [0001] The invention relates to a production process of a high-strength weather-resistant steel plate. Background technique [0002] High-strength weather-resistant steel plates are important materials for containers, railway carriages, and urban subway carriages. With the economic development of our country, the logistics industry is growing rapidly. High-strength weathering steel plays an important role in reducing weight, increasing speed, increasing freight volume, prolonging the service life of equipment and reducing logistics costs. High-strength weathering steel refers to σ s ≥450MPa weathering steel, this type of steel is mainly used in the manufacture of special containers, bridges and high-speed train carriages. Since high-strength weathering steel requires high corrosion resistance and high strength level, good formability and welding performance, it requires a high level of metallurgical process and equipment control.
