At present, the imbalance of the tool structure is that the production tool and the demand are not right. For example, the hard alloy cutters that users need are large, but the high-speed steel cutters are overproduced; the high-efficiency cutters that are urgently needed in modern manufacturing are large, but the low-grade standard cutters are overproduced.
In developed countries, cemented carbide tools have now dominated the tool, accounting for 70%. High-speed steel tools are shrinking at a rate of 1% to 2% per year, and the current proportion has fallen below 30%. The proportion of superhard tools such as diamond and cubic boron nitride is about 3%.
The tool for domestic manufacturing consumption, the proportion of cemented carbide tools has reached more than 50%, and the problem of disconnected supply and demand structure has been very serious. The consequence is that a large number of surplus high-speed steel tools are exported at low prices or domestically, while high-efficiency cemented carbide tools are Had to rely on a large number of imports, the import volume has increased from 0.9 billion US dollars in 2001 to 450 million US dollars in 2005 (about 3.6 billion yuan).
China currently produces about 80,000 tons of high-speed steel, accounting for about 40% of the world's total output, and consumes a lot of precious resources such as tungsten and molybdenum. This blind expansion and low level of repetition have resulted in a large surplus of high-speed steel tools produced and have to be sold at low prices, resulting in a low efficiency of a large number of tool manufacturers.
China's current annual output of cemented carbide is 16,000 tons, which also accounts for about 40% of the global total. However, the highest added value of cutting inserts for cemented carbide products is only 3,000 tons, accounting for only 20%. This situation, on the one hand, has caused insufficient supply of cemented carbide tools that are urgently needed in China, and on the other hand, the precious cemented carbide resources have not been fully utilized.
In terms of economic benefits, China's annual sales revenue of cemented carbide is about 560 million US dollars; Japan is only 40% of China's output, but its sales revenue is as high as 2.633 billion US dollars, and its proportion of blades (knives) is as high as 72%, so that resources have been obtained. By making full use of the company, the company has also achieved good results. China's tool industry should get some useful inspiration.
The Septic Tank is underwater sedimentation tank used for waste water treatment through the process of biological decomposition and drainage. Septic tanks allows a safe disposal of waste water and hence are widely popular in areas that have a poor drainage system or are off the mains sewage network. We can offer two kinds of septic tank : Frp Septic Tank and PE Septic Tank with assembly.
