Description
Technical Field
The utility model belongs to the technical field of the flow of water pipe hinders and decreases the test, concretely relates to metallurgical cooling arrangement's flow hinders and decreases test system.
Background
The metallurgical cooling equipment is a key component of the metallurgical equipment. As for the blast furnace staves, hundreds of staves are used for each blast furnace and installed on the furnace shell in sections. Circulating cooling water is introduced into the cooling water pipe cast in the cooling wall to cool the furnace shell of the blast furnace and maintain the normal production of the blast furnace. The water pipes of all the cooling walls are connected in series in a partition mode for supplying water, and the water flow speed in the water pipes of the cooling walls is generally 1.5-2.5 m/s according to different areas of the blast furnace. The diameter specification of the cooling water pipe adopted by the cooling wall is different according to the different furnace volumes of the blast furnace. In addition, the shape of the stave water pipe is also various, and particularly in the tuyere or taphole area, the shape of the stave water pipe is more complicated and varied in order to adapt to the shape of the tuyere or taphole area. For the above reasons, the flow resistance loss (resistance loss) of each stave is also different in the entire cooling system of the blast furnace. In order to ensure that the flow rate of cooling water in each area meets the requirement of blast furnace cooling, the resistance loss of each shape of cooling water pipe under a certain flow and water inlet pressure is accurately measured, specific parameter values of water pressure and water quantity of each section of cooling wall of a cooling system are calculated according to measured data, and the partition of the cooling wall and the type selection of equipment such as a water pump, a pipeline and the like are determined according to the specific parameter values.
After the diameter and the shape of the pipeline are determined, the flow resistance value of the pipeline is related to the pressure and the flow of the system, so when the flow resistance of the metallurgical cooling equipment is tested, the measurement is carried out under the preset pressure and flow. Generally, a set of test parameters are determined by up-and-down floating of preset pressure and flow by taking actual use condition parameters as reference standards. Such as: to accommodate a certain 1780m3The working condition of the cooling wall of the blast furnace and the test parameters are selected as follows: the pressure is 0.6MPa, and the flow rate is 8m respectively3/h、10m3/h、12m3H is used as the reference value. For test systems under other metallurgical cooling equipment use conditions, the selected parameters are determined separately.
At present, when a metallurgical cooling system is designed, empirical data is generally adopted to determine a resistance loss value, and in order to ensure normal use, large parameter allowance of water supply equipment is reserved, so that the capacity of the water supply equipment is wasted. Therefore, the flow resistance loss test of the metallurgical cooling equipment with each shape has important significance in accurately designing a water supply system of the metallurgical equipment, reducing equipment investment, saving energy consumption, reducing waste of water resources and the like.
