Description
Technical Field
The invention belongs to the technical field of metal material preparation, and particularly relates to a manufacturing process of a conical opening steel drum.
Background
In the current steel drum production process, the drum body, the drum cover and the drum bottom are all formed by processing cold-rolled steel plates, so that complicated and huge coating processes and equipment such as cleaning, degreasing, phosphating, spraying, drying and the like are needed. The above production process has the following disadvantages: (1) steel drum manufacturers need a whole set of cleaning, degreasing, phosphating, spraying and drying equipment, and the equipment is complex, huge, expensive in manufacturing cost and occupies a large factory. (2) The procedures of cleaning, degreasing, phosphorizing, spraying and drying are complex, the quality of the product is difficult to control, and the consumption of water, electricity, steam, degreasing agent, phosphorizing agent, coating, fuel and the like is large. (3) The steel drum has no means of spraying anticorrosive paint on the inner surface of the roller pipe of the opened drum. (4) 200-230L of cylindrical-conical composite open steel barrel (conical steel barrel for short) is used for containing foods such as tomato sauce, fruit juice and the like, the annual demand is about 400 thousands, and the steel barrel is formedThe surface of the steel plate is pretreated to remove oil stains on the surface of the steel plate, and then the steel plate is phosphated, cleaned and dried to form a phosphated film, so that the surface coating process can be carried out, a large amount of waste water and waste gas are generated in the processes of degreasing, phosphatizing, cleaning, drying, paint spraying and drying again, and the waste water generated after each barrel is finished is 0.03m3Exhaust gas 2000m3Only, but also causes serious pollution to the environment and the like.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a manufacturing process of a conical opening steel drum.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
the manufacturing process of the steel drum with the conical opening is characterized in that the drum cover, the drum bottom and the drum body of the steel drum are formed by processing galvanized steel coils or color-coated steel coils through cutting and blanking, welding seam reserving and trimming, rolling, seam welding and forming procedures in sequence, and the drum bottom and the drum body are sealed and rolled into a whole.
Preferably, the method for trimming the weld seam leaving the blank is scraping, edging or milling.
Preferably, the thickness of the color-coated steel coil is 0.5-1.5 mm.
Preferably, the volume of the steel barrel is 200-250L, the inner diameter of the upper opening is 500-571 mm, the inner diameter of the lower opening is 450-550 mm, and the barrel height is 800-1100 mm.
Preferably, the galvanized steel coil is an aluminum-zinc-plated steel coil or an aluminum-magnesium-zinc-plated steel coil.
Preferably, the steel barrel body is formed by processing a steel plate through the working procedures of cutting and blanking, reserving a blank for a welding seam and trimming, rolling, seam welding, coating the inner surface and the outer surface of the welding seam, coating and drying and barrel body forming in sequence.
Preferably, the inner and outer surfaces of the welding seam are coated by spraying, rolling or brushing.
Preferably, the barrel body forming process sequentially comprises an expansion cone, a curling edge, a flanging and an expansion rib.
Preferably, the outer surface of the steel barrel is partially or integrally subjected to multicolor silk-screen printing, multicolor thermal transfer printing or multicolor pad printing.
The process method for manufacturing the steel drum can greatly simplify the production process of the steel drum and almost omit all coating procedures such as cleaning, degreasing, phosphorizing, spraying, drying and the like. The expensive investment on the coating equipment at the rear section of the steel drum after production can be saved, the factory building for production can be saved, the quality of the coating inside and outside the steel drum can be improved and stabilized (the quality of the coating of the color-coated plate in a rolling way is higher than that of the coating in a spraying way), the coating quality of the steel drum is improved, and the consumption of process consumables such as water, electricity, steam and the like can be reduced; in addition, the galvanized or color-coated cold-rolled steel coil is directly processed to produce the steel drum, and the pretreatment process of the cold-rolled coil is removed, so that zero discharge of waste water, waste gas and waste residue is realized in the production process of the steel drum, and any position of the inner wall and the outer wall of the steel drum can be covered by the coating.
