The ore company's asking price has increased recently
"As the world's largest demander of iron ore, China's principles and positions in iron ore negotiations have never changed." China Steel Association said that the 40% minimum decline is based on the comprehensive measurement of steel production and market demand. It is concluded that in the downturn of the market, it is impossible to accept other prices. Experts said that China is the biggest bargaining chip in iron ore negotiations. First, iron ore is not bought. Due to the weakening demand for iron ore, the current global iron ore is in an “oversupplyâ€. In addition, mines other than the three major mines have emerged in recent years, which also have an impact on the global iron ore supply pattern. Second, steel companies are not good. At present, global steel companies, including Chinese steel mills, are still in sustained losses.
"But in the near future, we have become more and more passive in the negotiations." Xu Xiangchun, director of the steel network consulting department, said in an interview that the first is that Japan and South Korea took the lead in accepting the 33% decline in the negotiations. The original unified negotiating camp was one by one. Afterwards, the three major mines began to focus on the Chinese spot market, raising the spot price through spot bidding – the price of the Australian powder mine (Fe62%) reached CIF77 US dollars/ton, very close to Rio Tinto and Japan, South Korea. The customer reached a 33% reduction in the initial price; from the port spot price, 63.5% of the Indian mine port car tax price is 600 yuan / ton, 62% PB fine ore price is 600 yuan / ton, 65% of Brazil The price of coarse powder is 660 yuan / ton, up 10 yuan / ton to 20 yuan / ton.
“Actually, the over-imported ore in the first three months and the crude steel output that has grown against the trend have become the weight of the ore company’s asking price,†Xu Xiangchun said.
The data shows that China's crude steel output reached 46.46 million tons in May this year, an increase of 0.6% year-on-year. According to the crude steel output in May, the steel output this year will exceed 500 million tons.
3 billion tons of reserves for China's iron ore negotiations
“The discovery of the Dataigou iron ore mine in Benxi has undoubtedly weakened the strong position of the three major iron ore producers on the supply side. Combined with the recent efforts of China Steel Association to rectify the speculation of imported iron ore, it is likely to be on the way. Iron ore negotiations play an important role, putting pressure on the three major mining companies." Xu Xiangchun said.
It is understood that the Dataigou iron ore mine was discovered by Benxi City based on the geological data of the city for nearly 15 years to carry out regional geological surveys and secondary developments throughout the city. The ore reserves of this iron ore are equivalent to the total reserves of all iron ore mines in the Anshan and Benxi areas of Liaoning Province, which are rich in iron ore. They also have the characteristics of deep burial, deep extension of ore body, steep dip angle and large scale of ore body. The industrial type is a mixture of magnetite and hematite, which is an extra-large iron deposit with an iron ore grade between 25% and 62%.
Based on this estimate, the iron ore reserves that have been identified have exceeded 3 billion tons. According to theoretical estimates, it is possible to double the number and the local area is continuing to explore.
Three-dimensional composite drainage network is a new type of geosynthetic material. The structure is a three-dimensional geotechnical core, and both sides are adhered with needle-punched non-woven earthwork fabrics. The three-dimensional geotextile core includes a thick vertical rib and a beveled rib at the top and bottom. The groundwater that can be quickly drained from the road itself has a pore maintenance system that can block capillary water at high loads. At the same time, it can also play a role in isolation and foundation reinforcement, is a new type of geosynthetics. Three-dimensional composite drainage network made by the unique three-dimensional geotextile double-sided adhesive geotextile. Combined with geotextile filter effect and geotextile drainage and protection, to provide a complete "filter - drainage - protection" effect.
It is laid between foundation and base, which is used to discharge water between foundation and base, block capillary water and effectively combine it into the marginal drainage system. This structure automatically shortens the foundation drainage, drainage time significantly shorter, and can make the decrease in the number of the use of the material selection of foundation can be used with more fine material, low permeability of materials. Can extend the life of the road.
In the base layer laying three-dimensional composite drainage network to prevent the base of fine material into the ground floor, that is, play a role in isolation. Aggregate grass will enter the upper part of the geonet in a limited degree. In this way, the composite geotextile network also has a potential to limit the lateral movement of the aggregate base, in this way, its role is similar to the strengthening of the Geogrid. In general, the tensile strength and rigidity of the composite geotechnical drainage network is superior to many geogrids for foundation reinforcement, and this restriction will improve the supporting capacity of the foundation.
Road aging, cracks formed, most of the rain will enter the section. In this case, the three-dimensional composite drainage network directly laying under the road, instead of drainage of the foundation. The three-dimensional composite drainage network can be collected before the water enters the foundation / sub-base. But also in the three-dimensional composite drainage network at the bottom of a layer of film, to further prevent the water into the foundation. Whether it is for rigid roads or flexible road systems, this structure can extend the life of the road.
Three-dimensional composite drainage network is a new type of drainage geotechnical materials. To high-density polyethylene (HDPE) as raw materials, a special extrusion process from the processing, with three special structure. The middle ribs are rigid and longitudinally arranged to form drainage channels, and the upper and lower cross bars form support to prevent the geotextile from being embedded in the drainage channel, and maintain high drainage performance even under very high loads. Sided adhesive seepage geotextile composite use, with "filter - drainage - breathable - protection" comprehensive performance, is the most ideal drainage materials.
product usage
Mainly used for railway, highway, tunnel, municipal engineering, reservoirs, slope protection and other drainage works in a significant effect.
Features
1. Drainage strong (equivalent to one meter thick gravel drainage).
2. High tensile strength.
3. To reduce the probability of geotextile embedded core, to maintain long-term stability of the drainage.
4. Long-term high-pressure load (can withstand about 3000Ka compression load).
5. Corrosion-resistant, acid and alkali, long service life.
6. Construction convenience, shorten the construction period, reduce costs.
Seam and lap of three - dimensional composite drainage network
1, adjust the direction of geosynthetics, so that the length of the material roll perpendicular to the road.
2, composite geotechnical drainage network must be terminated, adjacent geotextile geotextile along the material roll lap.
3, the adjacent geotextile material of the geotextile core with white or yellow plastic buckle or polymer tape connected to connect the material roll. Along the length of the material roll, every 3 feet with a tape connected once.
4, The direction of the geotextile lap to overlap with the direction of packing. If the geotextile material is laid between the foundation / base layer and the base layer, continuous wedge welding, flat welding or stitching shall be carried out so that the upper layer of the overlapped geotextile is fixed. If stitching, it is recommended to use a flat seam method or a general seam method to achieve the minimum requirement for pin length.
