Brief Introduction of Steel Barrel Development

Steel Drums first appeared in the United States, has been 100 years of history. Drums is an important transportation containers , it has the following features.

First, the advantages :

1 . Good mechanical properties , pressure, impact resistance , resistance to impact ;

2 . Good sealing , easy to leak ;

3 . Environmental adaptability , heat, cold ;

4 . Convenient storage , loading and unloading the contents easy ;

5 . Drums barrier , suitable for packing volatile , air and moisture sensitive goods ;

6 . Most drums can be reused.

Second, the disadvantages :

1 . Their larger mass , cost , and the high cost of transportation and recycling ;

2 . Corrosive , requires special spraying ;

3 . Good thermal conductivity , not temperature sensitive goods packaging ;

Drums are now widely used for storing and shipping liquids, slurries , powders and solid food and light industry raw materials , packaging, flammable, explosive , toxic materials .

As the world economy, on the one hand the increasing demand for steel drums ; hand on product quality and functionality of a higher requirement. Thus promoting the steel drum manufacturing technology advancement . To promote the rapid development of the industry . Computer controlled automatic welding adoption of new technology popularization triple curling , drums and external surface automatic coating systems, advanced automatic detection equipment put into operation, cooperage special steel was developed to enable automated manufacturing equipment, steel drums the constant increase in the cooperage more mature technologies and processes . Currently cooperage advanced automatic production line can produce per hour, more than 600 steel drums , steel drums due to the thin , beautiful technology , convenient and multi-functional development, so that the specifications of steel drums , increased variety , quality and performance improvement , which greatly broadens the scope of the use of drums .

Section cooperage industry development overview

Since 1899 the United States made ​​the first manufacturing company in New York, armored steel drums only , since its only a hundred years of history . The advent of steel drums , instead of the cask followed for many centuries .

The early 1930s , Mobil Oil opened in Shanghai China 's first steel drums factories, subsequently , Texaco , Asia Petroleum, Shell and other foreign oil companies , have been in China to set up steel drums factory. At that time the main production barrels of gasoline and 53 gallons of kerosene party dress barrel. Before the liberation of our country , the domestic production of equipment used in steel drums all come from abroad .

1950s and 1960s, the Chinese steel drum industry is basically semi-mechanical , semi- manual operation, the time, only Shanghai , Tianjin, Yingkou several old factory formed steel drum production line, but the individual processes are still manual , most drums factories cooperage craft is : hand edging ; welding barrel body with oxygen ; using cutting garden machine bottom of the barrel under the ejector ; devices using a single head rolling barrel body ripples and cuffs ; with vertical roll Package with barrel machine , hand feed wheel seaming ; artificial painting, natural drying after painting ; manual handling between processes ; these processes , labor-intensive , but can not guarantee product quality.

The late fifties , made ​​by the former Soviet Union -made semi-automatic drawing seam welder come out. Many cooperage plant successively replaced by seam welding gas welding barrel body . With mechanical processing capacity cooperage plant , have generic American 1940s 200 l drums middle equipment, processes of transport between the extensive use of steel drums chain conveyor . 1972 Beijing cooper works first electrostatic painting, overhead conveyors , electric drying device, instead of hand painting or painting .

After the reform and opening up , many companies have technological transformation cooperage , so far, China has built 340 complete 200 l drums production line, however , the technology level and production capacity gap. Since 1986 , China's steel drums have their own manufacture of professional automatic production lines , and now there are about ten companies to develop and produce special steel drum manufacturing equipment and tooling .

In early 1979 , Beijing cooperage factory visits Japan first sent cooperage business, the end of our cooperage industry autarky situation, opened and technical exchanges and abroad cooper cooper prelude to the introduction of technology and equipment . Now, China 's cooperage enterprises have successively introduced the United States , Britain, Italy, Federal Republic of Germany , Switzerland, automatic seam welding machine 37 sets, 24 sets of equipment cooper middle .

China 's cooperage enterprises with foreign exchange technology, the introduction of advanced technology and equipment, to do the work of digestion and absorption of imported equipment and domestic cooperage machinery sentinel sentinel production and design , are effectively promoted the development of China's cooperage . China cooperage industry has undergone tremendous changes.

As China's scientific and technological development and opening-up policy, in recent years , cooperage process has been greatly improved , cooperage industry in the ongoing process of research and improvement , based on the already formed a relatively mature technology method , but also to improve the structure of the steel drum . The new process is mainly manifested in the following aspects:

( A ) to triple curling weight instead of the original two curling process , improve the impact resistance of steel drums , anti-leakage performance.

( 2 ) original circle cutting machine cutting and punch -pressure to the top end of the blanking pressure drums shaped composite mold process . Reduce labor intensity and improve production efficiency.

( 3 ) the original glue made ​​with brown sugar and seal packing improvements for the new steel drums sealant. Improve the drums anti-leakage performance.

( 4 ) The original length steel drums with steel sheet coil for the introduction of improved use of open-book device unwinding . Improving material utilization .

( 5 ) in the surface coating on the inner and outer drums , using the automatic airless spray , electrostatic painting or powder coating instead of the previous manual or mechanical spray with oven drying instead of the original natural drying , thereby increasing drums appearance quality .

In recent years, steel drums species also increased a lot , expanding the use of steel drums , steel drums improved performance. By bunghole form of points , there are closed , open , necking, in the mouth barrel ; by zoning , there are solid caustic barrels, rosin barrels, honey buckets , barrels carbide , yellow phosphorus barrels ; press the barrel points, there are cylindrical barrel, easy buckets , rectangular buckets , barrels and other cone ; divided by material , galvanized buckets, plastic composite barrels, plating barrels, tin barrels .

In order to adapt to the development of industry, steel drums , steel drums of standardization work is constantly being improved . Currently, the national standard steel drums have been formed, which is China's cooperage industry milestone.
