1 Introduction
Many steel companies in China are currently conducting or planning a new expansion of production ba, for the internal and external logistics of steel plant are volume, and the status of a rious lack of iron ore, scientific lection of the steel plant site, rational distribution of the various operating units. To find the best spatial loca-tion of all facilities for the plant, the enterpri's materials, equipment and human resources are efficiently ud, improve the utilization of various resources, to make the most productive, to catch up with the trend of China's iron and steel enterpris developme
nt and to fulfill the requirements of a large number of imported iron ore and the special region development.
2 The Work Sites Overall Layout of Iron and Steel Plants
2.1 The Principle of Overall Layout of Iron and Steel Plants
Site in the established arrangement of plants within the various venues, to adapt to urban planning and industrial development zone request, local natural conditions combined rational u of land, fully arranged in various venues, and create synergies.
(1) to adapt to urban planning; (2) the rational u of land; (3) The arrangements

for venues; (4) to create collaborative conditions; (5) the effective protection of the environment.
2.2 The Design Requirements of the Major Operating Units
(1) Production areas (plant): iron and steel plant production area is the main part of the overall layout,
should give priority to lect the appropriate location. According to the nature of the steel production plant, A larger percentage of transportation out-side the factory, so should clo to interface points of the main mode of transportation outside the factory: stations, terminals, roads in the vicinity; production area is large consumption of water and electricity facilities, should clo to the water sup-ply and Power supply; Production areas are also produced pollution venue, should be installed in the minimum space required frequency of clean wind upwind side; around the production area may be t aside for the development of room for expansion.
(2) Transport Facilities Location: When using the waterway transport outside the factory, we must lect the appropriate to the domestic terminal building sites, par-ticularly the u of raw materials for large ships dock, to be near the production area, and a reasonable convergence conditions. As much as possible make the unload-ing of materials directly to the production areas, finished packing can be directly transported to the terminal. When u the rail transportation, Should on the basis of convergence conditions, logistics direction, working conditions of the transfer, to lect a similar size of the marshalling factories, should leaves the factory to the possible expansion of the scale synchronization. Production areas and cities, termi-nals, stations, water sources, wage treatment plants, substations, residue field, con-struction site, residential sites and adjacent areas such as enterpri collaboration should be roads.

(3) Water and power facilities: the water sources of iron and steel plants are mainly come from the natural water sources such as river or a. Either surface or groundwa-ter sources, if ud as domestic water, should leaves health protection regulations required distance to prevent pollution. Sewage treatment plant should layout in the direction of water discharge, clo to the water into point. Treated wage discharge outlet should be located downstream of water points, and has more than 100m from the health protection.
(4) Health Protection belt: between steel mill plant and other sites or adjacent en-terpris, according to the concentration of pollutants emitted by factories, according to local environmental asssment requirements t a certain width of the area of health protection. In the zone, according to functional requirements for green, light pollution, the facilities can be arranged, but not often live in housing arranged.
(5) Java games: slag and industrial waste disposal sites should be lected in the main plant slag and industrial waste discharge direction, make full u of low-lying land, wasteland, valley and beach land. Stockpiling sites may require unified planning, acquisition phas, the stockpiles of the early stage generally not less than 10 years. Slag and industrial waste should be fully comprehensive utilization, save resources, reduce the impact of keeping occupied land, which is the trend of develo
pment.
(6) Residential area: subject to health protection standards and does not affect plant development, should clo the factory layout. Between residential areas and the

(7) Construction Site: construction site t up for the construction of various facili-ties. Therefore, its location should choo the fixed end of the factory building, and plant a certain distance between the left does not affect plant development. To facili-tate the u of permanent rail, road, water, electricity and other facilities.[2] Bad on the above basic principles and general layout of the design requirement-sof the major operating units, combined with Baosteel Zhanjiang New Area in the special conditions and the geographical situation of the factory location, environ-mental factors, to determine the overall layout of the various sites on the iron and steel plant, shown in figure 1.

3 Systematic Layout Planning of Iron and Steel Plant
3.1 SLP Method Introduction
Systematic Layout Planning was propod by Richard • Muther of American, and had been widely ud. This approach applies not only to the factory layout design and production systems, also can be ud for logistics centers, shops, hospitals, schools, and other rvice facilities layout design [3]. When the SLP method is applied to the overall layout of industrial facilities design, commonly ud procedure is to analyze the relationship between production process, and then the logistics of the op
eration unit and non-flow analysis, and make a weight, to obtain a comprehensive relationship between them, Finally, according to the intensity of the various operating units draw their location diagram.

3.2 Production Process
In the iron and steel plant, supply of raw materials and fuel from raw materials pre-pared workshops to the sinter plant and coking plant workshop, Produced sinter and coke been supplied to the iron workshop, supply the production of hot metal to steel-making plant, supply the liquid steel continuous to casting plant, supply the pro-duction of steel ingot to steel rolling plant, Shipped out the production of finished steel products, form of the whole plant production process. The relationship be-K
tween the workshop is the production process relations, we must keep this process, in general can not be changed.
3.3 Logistics Relations (Quantitative Relations)
The design according to an annual output of 10 million tons of steel to consider, ac-cording to the scale of production, material consumption indicators and quality of materials to calculate the materials number of input and output. According to the quantity of material flow between the production plants, power plants, ancillary fa-cilities, residential areas, establish the material flow start and end table, letters on

雅思考试内容According to material flow start and end table and material flow classification ta-ble, t out the logistics amount, material name and relationship level between the workshop, and then according to the logistics amount and the relationship level, drawn logistics relationship diagram, shown in Figure 2. From the logistics relation-ship diagram can be en the relationship level of each workshop, just the proximity degree, and as a basis for layout.

3.4 Non-logistics Relationship
Steel plant is basically the non-logistics relationships are the following: (1) interfer-ence of environmental pollution; (2) curity aspects, such as fire, explosions, and traffic accidents, etc.; (3) Energy supply and demand requirements; (4) ea of pro-duction management, as the ca may change.
Relationship between level of non-logistics division, according to the qualitative factors identified above, need to study in detail the relationship between the various workshops, in accordance with th
e hierarchy of importance of the relationship, show in table 3.
