The data governance refers to the process of transition from using sporadic data to using unified data, from few or no organization flow to enterprise-wide comprehensive data governance and from data confusion to well-organized data. In this paper, the standards and methods of data governance are formulated through the data extraction, cleaning and governance for the system of raw fuel procurement management, transportation management and storage management as well as exploring and researching the application processes combining with the current status of raw fuel procurement, transportation management and storage management. In the process of enterprise informatization, the enterprise development is enabled through informatization, which is the application mode of deep integration for new generation information technology and manufacturing industry as well as will become the core carrier of enterprise competitiveness.

The tubular belt conveyor is the main tool for materials transportation in modern productions. In the paper, the causes of such faults as off tracking, rolling over, tearing and tube expanding of belt for tubular belt conveyor are found out through analyzing its working principle and common various faults in operations in detail. As a result, the devices for preventing off tracking, tearing, spillage and tube expanding are manufactured and installed so that the loss of belt and fault rate of tubular belt conveyor could be effectively reduced as well as the normal operations of production are ensured.

In the paper, the transformation plan of increasing four sub lines in the area of car dumper inside station is proposed based on the weak transportation organization as well as study of capacity expansion and transformation of station aiming at the problem that the holding volume of cargo trains in railways bureau is so great that the lines inside rare earth steel station are limited. The effect of limited lines on efficiency of fetching and delivering train is relieved, traffic congestion inside plant is avoided as well as unloading capacity of goods allocation is improved so that the unloading of raw materials and productions are further ensured.

There are certain influences of fluorinion contained in barren liquor of organic amine on the effects of flue gas treatment in the process of roasting rare earth, so the accurate determination of fluorinion is required. Thus, the ion selective electrode method for determining the content of fluorinion in barren liquor of organic amine is established. The effects of pH value, temperature, accompanying ion and organic amine matrix on the determination results are studied as well as the interference elimination test of accompanying ion is carried out. The research results showed that the influences of organic amine matrix on determination of fluorine could be ignored, pH value was controlled at 5.0~6.0 with acetic acid-sodium acetate, interference of accompanying ion could be masked by adding 10 mL of total ionic strength adjustment buffer, analysis effect was the best with stirring for more than 5 min. when determined under the condition that the temperatures of detection and drawing working curves were the same. For this method, the mass concentration of fluorinion shows good linear relationship within the range of 0.04~40.00 μg/mL, detection limit is 0.021 μg/mL and quantification limit is 0.069 μg/mL.The standard recovery experiment for three barren liquor of organic amine samples is carried out based on this method and the recovery rate is 97.22%~104.10%. The method is applied for determining the fluorinion in three barren liquor of organic amine samples and the relative standard deviation (RSD, n=11) of results are 1.9%~2.4%. The results are basically consistent with those obtained with the chromatography.

The sample is dissolved by acid, residue is precipitated and filtered, the mixed flux of anhydrous sodium carbonate and boric acid is melted as well as it is mixed with acid dissolving test solution and the constant volume process is carried out. The contents of Si, Mn, P, Al and Cu in ferrotitanium are determined with the ICP-AES, the analytical spectral lines of elements to be determined and working parameters of instrument are optimized with this method as well as the disturbing effects of matrix elements Ti and Fe are investigated. The disturbing effects are eliminated with the mode of matrix matching and detection limit of the method is 0.000 3%~0.002 7%. The standard samples are determined with this method as well as measured values are consistent with certified values of all compositions, relative standard deviation (RSD, n=11) is 0.85%~9.03%, which could meet the analysis requirements of ferrotitanium.

The rare earth wear resistant steel produced by the production line of wide and thick plate of Baotou Steel is the national green design product. In this paper, the distribution of carbon emissions for products in such four stages as within enterprise, load of upstream, transportation stage and recycling by products and carbon emission of each working procedure in enterprise are analyzed as well as the technological paths of carbon drop for rare earth wear resistant steel products are discussed through the life cycle assessment (LCA) of product. The results showed that the carbon emission of rare earth wear resistant steel was mainly in enterprise, accounted for about 78.86% so that such processes as the iron making, sintering and coking as well as energy load in enterprise were the key points of carbon drop, recycle of by products played an active role in carbon drop and applications of advanced technologies made significant carbon drop possible. The carbon emissions in enterprise will be increased by developing high-performance rare earth wear resistant steel, but the effects of energy conservation and carbon drop for the society are significant so that it plays an active role in realizing carbon neutrality in our country to vigorously promote and apply rare earth wear resistant steel.

The waste emulsion is the oily wastewater in high concentration discharged in steel rolling process and the key of treatment is demulsification. In this paper, the suitable demulsification methods are selected through experimental study as well as the experimental conditions of electrooxidation demulsification and chemical flocculation demulsification are selected. The results showed that the most suitable demulsification method was electrooxidation, its optimum current range was 2.0~3.8 A and optimum voltage range was 140~200 V; the optimum coagulant for chemical flocculation demulsification was polyaluminum chloride. When the quantity added to is 1.5 g/L and pH value is adjusted to 7~9, the chemical oxygen demand (COD) in waste emulsion reduces to less than 8 000 mg/L, oil content reduces to less than 1 000 mg/L and suspended solids reduces to less than 1 500 mg/L.

In this paper, the dimensional changes of austenite grain for X80 pipeline steel with such conditions as different heating temperatures and heating times are studied with the thermal simulation method. The results showed that the austenite grain coarsening was obvious, which was from the minimum, about 35 μm to about 120 μm with the increase of heating temperature and soaking time; but if the soaking time was shorter (1 min), the austenite grain size still remained within 80 μm even if it was heated at 1 280 ℃, which showed the essence of fine grained steel. As a result, the mathematic model of austenite grain growth for X80 pipeline steel was obtained by the regression of experimental data, which could provide basis for industrial production.

The super large deposit of Nb, rare earth and iron in Bayan Obo is currently one of the mines with the most varieties of new minerals discovered in the world. The dolomite type ore with Nb and rare earth is the most widely distributed ore type in this area as well as it is with significant meanings to research its characteristics such as mineralogy. The dolomite type ore in East Mine of Bayan Obo is collected through field work as well as the petrographic identification and process mineralogy analysis are carried out. The results showed that the dolomite was distributed in subidiomorphic-xenomorphic granular form among fluorite, its particle size was uniform and generally 0.1~0.3 mm; the magnetite was mostly disseminated in subidiomorphic aggregation among fluorite and dolomite and its particle size was generally 0.3~1.0 mm. The main oxides of ore are CaO and MgO as well as the content of dolomite in this type of ore could reach 70%.
