Packaging steel strip production power system flow equilibrium profile

Packaging steel strip production balance of power system flow profile of hot rolled strip steel plant using water is mainly used for cooling, cooling mode can be divided into cooling roll or finished products directly to the cooling and cooling furnace slippery course, indirect cooling two types of underground oil lubricating oil etc. Can be used according to different purposes, cooling water circulating water, industrial water, tap water, sea water, etc. Water circulating water is used, the agglutinate reoccupy after precipitation treatment wastewater treatment equipment. The biggest heating furnace, roller to use credit, descaling, output roller adopts the circulating water cooling, the circulation rate in more than 95%. Industrial water, better than the circulating water quality, for detecting instrument and bearing cooling to high water quality requirements. The used water, some into the circulating water system, some industrial water loop, the use of the individual system. Tap water is used for detecting instrument and the indoor cooler cooling, but the dosage is less. Most used in heating furnace of slide rail cooling seawater. In addition, the output roller cooling, also have to take the waste water treatment equipment of circulating water and untreated water in front of the common use way, generally speaking, the more new type, high yield of rolling mill, the more the water especially in roll and the increase of the output roller cooling water. The amount of cooling water for 20 - in general 60 m/tons. Steam, compressed air generally consists of a steel power supply center, but also some & other inside the air compressor in steel rolling workshop; Users throughout the &; The nearby. As a heavy oil steam heater heat source is used, or used for atomizing burning. Compressed air in cylinder and valve opening and closing device such as a power source or meter instrument of cooling, etc. - cooling water consumption are shown in table 2 48, steam, compressed air, the amount of actual lift - such as table 2 49, as shown in the flow of cooling water balance instance - as shown in figure 2 63? As shown in 69.
