1、 General Introduction
1.1、summary
India K Company is located in kerala province, southwest of India, the distance from Koppal is 14Km; from Hospet 16Km; and from NH-63 Expressway 6Km.
Transportation by train is very convenient, because the distance from railway station is only 6Km.
There are 2 sets of 125m3 blast furnace, foundry plant, material yard, facility such as power plant, air compressor station, pump station, fuel device etc. in the cooperation.
In order to save energy consumption, increase utilization factor of blast furnace to acquire better economic index, K cooperation decide to build a new set of sinter plant. This blast furnace shall adopt 60% agglomeration instead of raw ore. So that K cooperation trusts China Shougang international trade & engineering company to design a new sinter plant with annual production capacity of 530.000t.
1.2、 Design Basis
In accordance with the development plan, made by of India K Company in October 2006, for constructing one sintering plant with an annual capacity of 500,000 tons, it is preliminarily designed to build one 50m2 belt sintering machine to be provided with one 60m2 circular cooler so as to turn out 530,000 tons of sintered ores per year.
1.3、 Main Contents of Design
Design contents of the project include main production process system, public and auxiliary facilities in the sintering plant area; the production process system includes: flux and fuel crushing system, batching system, blending system, sintering and cooling system, sintering fan system and finished product screening system.
Public and auxiliary facilities include: power distribution and power supply facilities, water supply and drainage facilities, ventilation and dust removal facilities, thermal power facilities, automation control facilities, instruments and apparatuses, communication facilities, testing and chemical analysis facilities, general layout and transport facilities.
1.4、 Design Principle and Design Characteristics
Engineering design scheme complies with the design principle of practicality, reliability and economic rationality, and adopts advanced technology properly, so as to realize the production target of high quality, high efficiency and low consumption. Meanwhile, it can meet the requirements of environmental protection, labor protection, safety production, etc. Therefore, the design is featured in following:
(1)Batching system adopts computer automatic control batching, is equipped with belt electronic scales, frequency conversion and speed regulation feeding equipment so as to increase the accuracy of raw materials by weight.
(2)Add lime hydrate to sintering mixture to strengthen the process of balling and sintering and increase the production quality.
(3)Equip with hearth layer system. Hearth layer can not only protect the bar grate and pallet, but also increase the gas permeability of batch layer, reduce the dust content of flue gas, protect the equipment and environment.
(4)Adopts large air flow, low carbon and thick sinter bed sintering technology to increase the thickness of batch layer, reduce the fuel consumption and increase the sinter quality; planned sintering batch layer thickness of the scheme is 500mm.
(5)Main machine adopts belt sintering machine and circular cooler process; It has the characteristics of small floor area, compact structure and high cooling efficiency, and becomes a presently proven, reliable, economical and reasonable sintering process.
(6)Equipped with complete flue gas dust removal facilities, smoke and dust discharge concentration<100mg/m3.
(7)Dust collected by dust collector within the sintering plant area should be pneumatically conveyed to the ash bin in the batching building by means of a vacuum suction and discharge tank car (prepared by India K Company), and then returns for sintering batching.
(8)Production system equipment for the main sintering process flow adopts PLC to realize the centralized control of whole production process of the main process flow. Key production posts are equipped with industrial TV monitoring and production dispatching instruction system, and an overall production operation and management can be realized in the master control room.
(9)General layout of the plant is compact and reasonable; Process flow is smooth and optimized.
1.5、 Division of Design
Design Scope of Chinese Party:
The general layout and vertical arrangement of buildings and structures, road and virescence within the land used.
Responsibility scope of Indian Party:
Demolition and relocation of all kinds of buildings and structures, ground and underground pipelines within the land used; TOPs of external water supply and drainage, power supply, compressed air, and etc.; road transportation equipment, metering facilities, etc.
1.6、 Engineering Design Scope and External Joints
1.6.1 Engineering Design Scope
Engineering design scope of the sintering machine includes a process starting from flux and fuel crushing building and batching building of raw materials to the transfer station in the blast furnace area where the sintered ore is brought through No.4 and No. 5 finished product belt conveyors, respectively; and includes the design of general layout, processes, equipment, civil engineering, electric, automation, telecommunication, warm air, water supply and drainage, thermal power, fuel gas, fire protection and other disciplines engineering designs within the scope.
