Steel Barrel Production Training - Technical Art 1

First, the type of steel drums
According to different classification methods, drums can be divided into several types.
1, according to the size of a container drums: drums (200 liters and above), the barrel (200 liters - 80 liters) and kegs (80 liters less).
2, according to type of bung steel drums: Closed Barrel (small mouth barrels, in the open drum) and the opening drum (straight opening drums, steel drums and openings conical opening necking drums).
3, according to steel drums coating Category: paint bucket, galvanized bucket, plating barrels, Tu barrels and so on. There steel plastic composite barrels, pre-coated sheet steel drums, steel drums coated plates.
4, according to the material thickness of steel drums: Heavy Barrel (1.5mm), medium-sized buckets (1.2mm), second medium barrel (1.0mm) and light barrel (0.8mm).
5, according to the commercial transportation of steel drums: sales packaging and transport packaging drums drums.
6, according to steel drums containing dangerous goods of: Ⅰ level, Ⅱ and Ⅲ. Its steel drum test requirements are different.
Second, the capacity of steel drums
Steel drum capacity is divided into nominal capacity (standard capacity) and the actual capacity. Proportion of goods of different costumes, different seasons and temperature environment, safety capacity is different, the nominal capacity is only a basic guarantee.Under normal circumstances, the actual capacity than the nominal capacity of around 5%. Security capacity based steel containing articles and different environment, scientific calculated. This method of calculation in the "steel drum manufacturing technology" (Professional Edition) with instructions.
Correct choice of steel drums security capacity, dressed reasonable amount of cargo, is to ensure the basic conditions for transport safety.
Third, the drums of raw materials
1, according to the thickness of points, there are heavy barrels, medium-sized buckets, barrels and light second medium barrel. Containing different proportion of goods, steel drums of material thickness is somewhat different.
2, according to type of material coating, whether coated steel (cold rolled), galvanized sheet, pre-coated steel, coated steel. Depending on different conditions, use of different materials.
3, the raw performance, quality, production process for steel drums tremendous impact.Example: Material tough, too brittle, prone to rupture, rebound, affecting the quality. Poor surface quality, easy to produce tensile cracking phenomenon. Thickness of the ultra-poor, affecting the quality of curling.
Fourth, the drums of diameter series
Determine the diameter of the drums, to comply with the dimensional requirements of international transport of goods determined non-compliance would result in wasted space transportation, or not allowed to export. Relevant national standards are "rigid straight cube transport package size series", "cylinder transport package size series", "cargo packaging unit size" and "transport package size limits." In the "steel drum manufacturing technology" can be found in the appendix. Traditional drums diameter size of the problem, the solution: W rib barrel, necking barrel, the international standard steel drums.
Fifth, the structural steel drums
1, the basic structure of steel drums: bottom of the barrel, barrel body, barrel top closure (closed barrel closures and openings barrel closure).
2, steel drums structural development:
· Tapered steel structure, purpose;
· Opening drums of the structure, use and closure of the type;
· Do not leave residue drums structure: closure structures, barrel roof structure.
· Plastic composite barrel structure and purpose.
ODD barrels for the roof structure as the national standard steel drums, steel drums with international standards, the tapered barrels and plastic composite barrel structure comparison.

Six, auxiliary materials for steel drums
1, the steel drum coating: environmental protection requirements and the development of water-based coatings, the development of pre-coated sheet, film development board.
2, steel drums coating: interior paint and interior cargo compatibility, construction conditions.

3, Sealant: Sealant choice, and the compatibility of the goods contained therein.
