The description of my job

00Nowadays, most big and advanced factories need more equipments, less workers. So a new vocation brought out for the managers to control so many machines with few labours, we called the new line-Automatic project control.02br
02br
02font02br
00We use automatic control system mostly in iron works where there are lots of huge machines which are hardly operated by manpower, and sometimes it’s not convenient for workers to control the big machines just beside them, as the long distance between control center and the spot where the machines locate will take jockey so much time. For solve this problem, we begin to try to use a new system, which include industrial computer, low-tension apparatus, relay, switch, transformer, and the main part-we called it PLC(Programmable Logic Controller). By the industrial drawing software we can add all the machines need to be operated on the screen of a computer, and their location on screen is accord to the actual location outside. After completeing the drawing, we distribute a memory address of database to each unit displayed on screen, and then we will go on and edit the programme on the computer and download it into the CPU of PLC. Finally, we will connect all the computers and PLCs by Industrial Ethernet or Profibus. Thus, we have set up the whole control system, and the programme which control all the machines could absolute run automatically. The worker can operate one of the machines individually by just double-click on the screen, and most of the time, he can leave computers take their course by themselves. If we can disregard the failure of control-apparatus, it will be enough for only one person sit in the center control room, and the only thing what to do for him is just cleaning. With the nicer condition of machines outside, we can finish a control system as complicated as the one which used in a medium-sized iron works(about 450 steres) within fifteen days by three engineers. We are trying to serve the clients(the managers of factories mostly) with the most beautiful pictures and unimpeachable program. 02br

00What’s happened in iron works?02br
02br
001.00 00Plenty of coke and iron ore was send to the mouth of the furnace, there, the material passed first jaws-we called upper cover and got into the medium part of the furnace, and then, they went on passed the second jaws-we called nether cover and got into the abdomen of furnace. The action of the two jawses is separate the harmful gas from the air by alternate opening.02br
02br
02br
02br
02br
02br
002.00 00Hold by the strong press of the flaming air from dozen of meatus placed into the furnace, the material began to melt together in the air, and at the first time to see that I even could not believe the material can step to melting in a floating state!!!02br
02br
00 02br
02br
003.00 00The coke was burned out inside the furnace and turned into carbon monoxide. The gas passed through a pipeline and went into a gravitational dust catcher, where the bigger granules were filtrated off.02br
02br
00 02br
02br
004.00 00Then, the gas come to other dust catch system, we called hop-pocket dust cacther, where almost all impurity were filtrated off.02br
02br
00 02br
02br
005.00 00In the end, the gas entered heat air stove(maybe it’s called blast stove in USA), and was heated up to a high temperature about 1500 Celsius. With the big air pressure made by several huge fans outside, the gas was sent to the twelve meatus we mentioned above. And hereto, we have toured through an orbicular circulation fully. 02br

00The melting material become to melton iron gradually and flowed out from a confined exit. Generally, if there are copulate steel-making workshops, the melton iron will be sent to those workshops directly and be made into steel there. If there no workshops like that, the melton iron will be moulded into rion blocks at normal temperature, and carried to other places to remade into steel.02br

00We mainly use the products and softwares from SIEMENS and GE corporation. We look forward to use our native products.02br
