Introduction of New Galvanized Steel Coil Process

The invention relates to a production process of a galvanized steel coil, which comprises the following steps: firstly, uncoiling the cold-rolled hard steel coil, cutting the head and tail, and welding; secondly, preparing a degreasing solution, and sequentially immersing the treated steel coil in the degreasing solution, Brushing with brush rollers, drying with hot air, and processing through the inlet loop; then annealing the obtained steel coil; S4, putting the annealed steel coil into a zinc pot, soaking for 4-5 seconds, and then purging with an air knife, cooling, and hot air in sequence. After drying and smoothing, the galvanized steel coil is obtained; then the galvanized steel coil is heated, and after being taken out, the passivation droplets are sucked on the surface of the galvanized steel coil with a straw, and dried; the treated steel coil is treated with anti-fingerprint coating, and the After the looper is exported, oil is applied; the obtained steel coil is slit, coiled, uncoiled and packaged. The production process of the galvanized steel coil in the present invention can effectively remove pollutants such as dust and iron powder firmly adhered to the surface of the steel coil, which is beneficial to improve the quality of the galvanized steel coil, thereby prolonging the life of the galvanized steel coil. The service life, this new process makes the best galvanized steel coil, it will enhance resistance of galvanized steel coil.

Features of the new galvanized steel coil process

A production process of galvanized steel coil is characterized in that the production process of galvanized steel coil includes the following steps: after the cold-rolled hard steel coil is uncoiled by an uncoiler, the head is cut and the tail is cut, and then welded by an automatic seam welder. Weigh 15-25 parts of sodium phosphate and 130-140 parts of deionized water in proportion, put them in a glass container, stir at room temperature to completely dissolve the sodium phosphate, adjust the pH of the solution to 5-6, and then add 2- 3 parts of gallium chloride and 15-25 parts of sodium silicate are stirred at 600-650r/min for 3-5h at room temperature to prepare a degreasing solution, and then the cold-rolled hard steel coils treated by S1 are immersed in sequence Degreasing liquid, brushing with brush rollers, drying with hot air, and looping through the entrance to obtain degreased cold-rolled hard steel coils. The obtained degreasing cold-rolled hard steel coil is annealed to obtain an annealed steel coil. Finally, galvanize the product to obtain galvanized steel coil, which is the best galvanized steel coil and enhance resistance of galvanized steel coil.

Introduction of The best galvanized steel coil

The invention relates to the technical field of steel coil processing, in particular to a production process of a galvanized steel coil. The production process of hot galvanized steel coil takes cold-rolled hard steel coil as raw material, and immerses the cold-rolled hard steel coil in a molten zinc bath to make the surface adhere to a layer of zinc. Galvanized steel coil has excellent corrosion resistance and can prolong its service life. It is widely used in construction, light industry, automobile, agriculture, animal husbandry, fishery and commerce. For example, the construction industry is mainly used to manufacture anti-corrosion industrial and civil building roof panels. , roof grilles, etc.; light industry uses it to make home appliance shells, civil chimneys, kitchen utensils, etc.; automobile industry is mainly used to manufacture corrosion-resistant parts of cars; agriculture, animal husbandry and fishery are mainly used for grain storage and transportation, meat and aquatic products It is mainly used for storage and transportation of materials, packaging tools, etc.

In order to enhance resistance of galvanized steel coil, in the prior art, the galvanized steel coil is usually coated with a topcoat layer, and the topcoat layer is usually composed of acrylic paint, aliphatic polyurethane paint or acrylic polyurethane paint, and these paints have good weather resistance and corrosion resistance, so as to prolong the service life of the galvanized steel coil.

Enhance resistance of galvanized steel coil

In view of the deficiencies in the prior art, the purpose of the present invention is to provide a production process of galvanized steel coil, which can effectively prevent the pollution of dust, iron powder and the like firmly adhered to the surface of the steel coil. It is beneficial to enhance resistance of galvanized steel coil and prolong the service life of galvanized steel coil, which is the best galvanized steel coil.
