Latest ArticlesThe stope highway of Baiyunebo Iron Mine is constructed with gravel grading materials, a lot of dust and exhaust gas are produced during the operation of mine-cars and sprinklers, which not only cause great damage to personal and environment, but also have security risks when the heavily-loaded sprinklers go down the slope. Through research and analysis of the fixed highway running condition in Baiyunebo Iron Mine, a set of electric control spraying system of the stope is built to complete the watering dust suppression of the fixed highway and realize the safety production and environmental protection of the highway in the mine stope.
This paper mainly analyzes the function of hand-held meter reading instrument in water fee management system of Baiyunebo Iron Mine and how to integrate it into the existing water fee collection management system. At the same time, it also briefly introduces the development tools of the system.
This paper mainly introduces the current situation of rare earth protection management in Baiyunebo Iron Mine, and analyzes the function of video surveillance system. In this paper, video surveillance system is used as a tool to realize the transformation of management mode for rare earth resources through the integration of technology, management, rules and regulations. And the enormous social benefits that produced after the transformation of management mode is analyzed in detail.
This paper discusses how to use the characteristics of network model of VMWARE software and how to select and set up the virtual local area network that complies with the experimental platform to obtain an efficient and practical network experiment test platform at a very low price. The virtual local area network can be used for all kinds of server environment debugging, intrusion and defense technology, software testing and so on, so as to achieve the purpose of experimental test which needs to be completed.
Retrospecting the history of discovery, exploration and exploitation for the main and east ore body in Bayan Obo, this paper summarizes the research and industry practice on beneficiation and hydrometallurgy of Bayan Obo rare earth mine. It also overviews the research and development course of rare earth functional materials, points out that the research and comprehensive utilization of Bayan Obo rare earth resource interrelates with the generation and development of rare earth industry in China, and proposes some problems that need to be further understood in the current and future development of rare earth industry.
According to the construction lagging of the rock phase Ⅱ and ore reduction belt convey system in East stope, and the slip mass in C zone that affects the normal advancing of the stope, the delineation of stope boundary is redetermined, the highway exploit layout under 1404 m is ascertained, the production scale of the stope is verified, and the safety measures of the slope is confirmed, so as to ensure the normal production of the stope.
In this paper, the influence factors of desalting water system assorted with coke dry quenching are studied, part of the desalting water process is optimized, and the pretreatment and dosing system are modified. In summer, adding the non-oxidizing fungicides to the original water tank has osmotic stripping effect on the sediment and slime of the raw water, and it strictly controlled the pollution factors of the system.
In November 2016, the furnace condition of No.7 blast furnace in Baotou Steel is poor: high pressure difference, great fluctuation of furnace temperature and low gas utilization rate. Through analysis, the adjustment method is: stabilize the fuel ratio, thereby stabilizing the furnace temperature; on the premise of ensuring the central airflow, reduce the thickness of the edge material layer; enlarge ore difference and improve gas utilization; reduce the amount of stocking sinter, improve the permeability of the column and reduce the pressure difference.
In this paper, it aims at the problems encountered after the commissioning of pulverized coal injection system for two large blast furnaces in Baotou Steel, such as serious silo deformation of roof scrubber, large consumption of nitrogen injection, frequently worn-out of branch injection pipe and spray gun soft connection. By means of gradually improving the production process, equipment defects and poor ventilation, strengthening the silo, adjusting the pipeline air nozzle, increasing operation methods, improving operation technique and reducing injection air volume to reduce the energy consumption and to solve the problems in production.
The smelting of high Cr alloy steel has always been the difficulty of converter smelting. During the smelting of high Cr alloy steel in Steel-melting Plant of Baotou Steel, converter bottom blowing system is optimized through adjusting the converter loading system as well as the remaining slag double slag process and so on. The results show that the optimization of bottom blowing system ensures the melting for a large number of alloys during the tapping process and reduces the carbon and oxygen concentration product, and provides a basis for smooth smelting, solving the problem of high alloy smelting.
