Reached under the pressure of the objectives of the government to close the polluting capacity exceeded by the end of 2010, it seems that Chinese factories are not fully explain its steel production.
Saudi Arabia appreciates the mill that the production of crude steel in the country under-reported by as many as 47 million tons and the production of pig iron from 44 million tons.
Consequently, the productionof crude steel in 2010 were as high as 674 million tons. Published in comparison with a value of 627 million tonnes by the National Bureau of Statistics of China.
Some clues about the true extent of the production of steel has been issued in the current production data for the year 2011, after the government ended the 2010 campaign against the obsolete steel production capacity. This shows the production of steel at the beginning of this year is running at an annual rate of production of 706 million tons.
RespectMEPs with estimates that the production of crude steel in 2010, culminating with an annual rate of 739 million tons. The highest annual rate of run after the Chinese National Bureau of Statistics for 2010 indicated, the 674 million tons. This means that the production of crude steel, earlier this year, which was traditionally a period of poor performance in the Chinese steel industry, 5% higher than peak levels in 2010. Analysts agree that this is unlikely.
The product model Sitop PSU400M SITOP modularField becomes high DC voltages in the range of input voltage 200-900 volts broader extremely efficient in a market regulated 24 volts DC.
SITOP PSU400M suitable for drive applications, the conventional system of automation tools and textile machines for wind turbines Telsmith switch.
The power range of Siemens Industry Automation Division has expanded with a converter that converts DC voltages efficiently from 200 V900 V to 24 V.
Wide range of fitness
SITOP PSU400M is suitable for connection to the bus voltage of power systems and networks to connect to the battery. The output voltage can be adjusted with a potentiometer between 24 V and 28.8 V to 24 V, the converter provides a current rating of 20 A, it can provide, if necessary, by another 50 per cent extra power for 5 seconds. This provides 30 A current loads with high inrush currents, such ascapacitive loads are connected without any problems. Yemen mill for sale new device has an alarm contact for "24 V OK".
The design of the 400M PSU
400M power supply is designed as a series of all types of products SITOP for rail mounting. The DC / DC converter is 90 mm in width and can be used to more than 70 degrees Celsius to temperatures of minus 25 The device is in a rugged metal housing to withstand shock and vibration, so thatmay be near or directly into the machine. There is also a high level of electromagnetic compatibility (EMC), which is a specific requirement in the DC Circuit characterized by unity.
The new network is part of Siemens for a broad spectrum of different applications. PSU400M can be used with frequency, type, for example, an efficient and affordable plan cut in which the energy stored in the intermediate circuit used to supply power to 24 Vnecessary to ensure the machine does a safe and controlled manner.
An example of use of shock and vibration DC / DC converter with batteries is to control the angle of wind turbine blades. For security reasons, the energy for the supply of these so-called step controller is powered independently of the electricity network.
