Table 4 plus standard recovery test plus recovery amount recovery rate oral steel ladle modification accelerator 3 sample analysis and analysis results are shown in Table 5. 11 precision tests on ladle modification accelerator, sub-table 5 sample precision The test number analysis value (n average No. 1 No. 2 - AES method for the determination of metal aluminum content in metallurgical slag, the detection data precision is good, fully meet the modern steel process production requirements.
4 Conclusion-AES method for the determination of metal aluminum content in metallurgical slag, the detection speed is fast, the analysis time is greatly shortened, and the use of modern analytical instruments greatly improves the degree of automation, and the patent information + instrument compressed air purification system application is reduced ( Patent): Shanghai Meishan Iron and Steel Co., Ltd. invention (design): Guo Haibin; Yang Jun; Tang Quangang pipe, outlet pipe, dehumidifier and dryer, also includes at least one dust removal and decontamination tank and a gas storage tank, The bottom of the dust removal and decontamination tank and the regulated gas storage tank is provided with a sewage outlet, the intake pipe is connected to the inlet of the dust removal and decontamination tank, the outlet of the dust removal and decontamination tank is connected to the inlet of the regulated gas storage tank, and the outlet of the regulated gas storage tank is The dehumidifier and dryer in series are connected to the trachea. In this way, the compressed air first enters the dust removal and decontamination tank through the intake pipe, and while the tank expands, the dust deposits, the compressed air is purified, and then enters the regulated gas storage tank, thereby suppressing the pressure fluctuation in the pipeline. After the dehumidifier and the dryer are output from the air outlet pipe, the purity and pressure requirements of the use occasion can be satisfied, the equipment is small, the operation and maintenance are simple and easy, the cost is low, and the labor intensity is small.
(This journal) has low labor intensity, and its test data is accurate and reliable, fully meeting the requirements of modern steel process production.
