The first kiln ore pellet plant renovation project Documentary section
Speed, fast frequency, large-scale, high intelligence Siemens products; 66 Intelligent temperature controller, 4 sets of ultrasonic level meter, also used in all technologically advanced imported equipment; a 12 - transmission of information using the advanced \bus \They have come up design} and then transferred to some of the projects commissioned to design the addition to the specific unit plus engineering design, the meter control room using the computer fine L1. Detection points and 25 meter box installation construction design and drafting tasks. After a tight construction organization, juice control room installation and commissioning of the meter, metering, and automation facilities are more than 100 sets, all by section, into process operation, without leaving any last work, the new laying more than 10,000 m cable is not a \. Chain grate machine, annular cooler programmable controller, is commissioned by China Metallurgical Industry Automation Institute designed by international standards, Shougang Mining Company assumed total control room operating cabinet with 8 disk task. Reconstruction of sectional kiln pellet production process after the implementation of automatic control and digital display,[link widoczny dla zalogowanych], all through a variety of meters and meter devices on-site collection of information, the current vector of transmission of PLC reduced the signal processing parameters to achieve. Control of the chain grate construction of stations, because the hardware uses a PIC Siemens products, equipment installation and the Automation Institute of Metallurgy is responsible. Shougang Mining Company account bear only on-site control room and the current signal acquisition parameters of the transmission. After installation, commissioning docking with the current signal when the abnormal phenomenon, cut off the 5-way signal in any way,[link widoczny dla zalogowanych], the other 4 more than the upper limit of the current meter range, a serious distortion of the outgoing parameters. The investigation. Field data transmission parameters and the current signal no problem. Clearly the problem lies in the PLC hardware. The original abnormal phenomenon is due to the negative input current signal of the negative terminal end and PLC24V generated potential difference. Technical staff will input current signal and the PIC controller, the negative side of the reference potential short circuit, the problem is solved. The chain grate machine before the transformation material thickness monitoring system, using the \In the production process, once the stacker, will inevitably lead to deformation of the probe, leading to failure to monitor. To address this issue, namely, the gay squad control room redesign of the \Pellet plant Fan ESP main pressure and flow monitoring, design and construction of the unit entrusted with the \main control room is not conducive to centralized control. Squad in time to change the design, with \. After closing the kiln pellet production process transformation 6 large system, 17O a point field signal collected by the real-time instrumentation, PLC programmable control input 3 sub-station, information processing, on the one hand signals to industry control microcomputer for signal display; the other hand through the various process parameters DP bus pass (Master Control Room) PIC programmable control station, through the system software, the chain grate, rotary kiln, annular cooler and other main equipment to monitor the implementation of and automatic control. Go through the main control room of the industrial control computer,[link widoczny dla zalogowanych], the signals to the secondary server, and the factory computer management system docked to form the covers over the whole plant industrial site computer network management, to the domestic first-class technical level of automatic control. Liu Chengjun ABBMV2000T Shougang Mining Company launched a new transmitter in China in June 2000, Shanghai Zi Jiang Wei Ertai Instrument Co.,[link widoczny dla zalogowanych], Ltd. and ABB Group of companies, launched simultaneously in Shanghai and Germany ABBHartmann (Braun's new Intelligent Multi MV2OOOT differential pressure / pressure transmitter. Hartmann (Braun Company in the preceding series of products for the AS800, which uses HART protocol, accuracy of 0.1, range ratio of about 3O: 1. 1999 launch of the new product has the following advantages MV2OOOT : 1 transmitter design using components from the electrical components with integrated pressure sensor assembly and the button control unit with amplifier, based on measurement range and measurement variables, the use of micro-shaped silicon sensors, solid-state sensor or a variety of ceramic complex multi-parameter measurement sensor technology ((P, P, T, QV, QM). 2 high precision, with 0.075%, 0.05 two.
