Problems solved by technology
[0003] Due to the extremely thin thickness, if the continuous hot-dip galvanizing process with the existing conventional thickness (>0.3mm) is used for production, it is prone to wrinkles, poor welding, chrome marks, smooth flowering, narrowing, wave shape, broken strips, etc. Defects, strength and hardness and other properties can not meet customer requirements

Embodiment 1
[0107] Three kinds of galvanized substrates of 0.27×1000mm, 0.2×1000mm and 0.16×1000mm were prepared according to the following process. Regarding the representation of steel plate specifications, such as 0.27×1000mm, the thickness of the steel plate is 0.27mm and the width is 1000mm.
[0108] 1) Incoming raw material roll inspection (up roll inspection)
[0109] ①Thickness tolerance: ±0.004mm, width tolerance: 5~6mm.
[0110] ②Edge quality: no edge cracks, to ensure smooth cutting edge quality without burrs, the shear layer should not be larger than the tear layer.
[0111] ③ Plate shape quality: no large side waves, rib waves, uplifts, and no serious compound waves.
[0112] ④The raw material roll at the entrance should be placed on the V-shaped large saddle, and the roll-up trolley and the saddle should be covered with rubber to prevent the roll from collapsing and bruising.
[0113] ⑤ The inlet looper is full of sleeves during welding. If there is a deviation, the cpc c...

Abstract
The invention provides a continuous hot galvanizing process of an ultra-thin galvanized substrate for color coating, which is characterized in that according to bottleneck links of production and quality of the ultra-thin galvanized substrate (less than or equal to 0.3 mm) for color coating, a process of welding, annealing, galvanizing, finishing, withdrawing and straightening and curling is formulated; the production, surface and appearance quality problems of poor welding, wrinkles, wave shapes, strip breakage and the like of ultra-thin specifications are effectively controlled, and the product quality is greatly improved. Through effective cooperation of tension of all sections, accidents such as deviation, narrowing and breakage of the ultra-thin steel strip are effectively eradicated, and the high-speed and constant-speed production stability of the ultra-thin steel strip is ensured. An incomplete low-temperature annealing process is adopted, the annealed structure is a semi-fibrous structure, and the hardness, the strength and the toughness meet the use requirements of customers on strength improvement and thinning of the color-coated sheet.
Description
technical field [0001] The invention belongs to the technical field of metal materials, and in particular relates to a continuous hot-dip galvanizing process for an ultra-thin galvanized substrate for color coating. Background technique [0002] With the increase of domestic and foreign infrastructure projects, the market demand for ultra-thin color-coated boards for construction such as disposable fences and simple color-board houses has increased, and there is a certain amount of ultra-thin color-coated boards with a thickness of ≤0.3mm The color-coated substrate is an extremely thin hot-dip galvanized sheet, and large and medium-sized steel companies at home and abroad hardly produce hot-dip galvanized steel sheets of this specification. Do some research on the production process of zinc steel sheet. [0003] Due to the extremely thin thickness, if the existing continuous hot-dip galvanizing process with conventional thickness (>0.3mm) is used for production, wrinkles...
