There are such problems as the temperature at gas inlet of burner for Kalugin top combustion stove is too high, package is red as well as weld joint of gas pipeline cracks and leaks. After soldering and surface air cooling, the effects are not obvious. It is found that the internal refractory bricks collapse through opening pore on the pipeline. Thus, the special measures are taken as well as the area is sprayed and with lining making to repair so that the hot air temperature returns to normal, blast temperature of blast furnace keeps at 1 200 ℃ for normal production and the effects are obvious.

In the article, it is introduced the rail is deformed violently in rolling process and internal compactness is changed greatly due to the cross section size of ingot blank increases when rolling 60 kg/m rail using ingot blank with the cross section of 320 mm×415 mm instead of that with the cross section of 280 mm×380 mm in the production of rail. In order to ensure the product quality in rolling process, the roller of each rolling mill is adjusted to ensure stable as rolled state. After rolling the finished products, the macrostructure, microstructure, grain size and impact performance of rail are tested and analyzed with such equipment as the optical microscope, scanning electron microscope and impact testing apparatus. The results showed that the compression ratio of ingot blank was increased by rolling rail with large size ingot blank so that such mechanical properties as grain size and impact of rail could be improved.

In the paper, it is found that the hardness and wear resistance of working layer for cast iron roll are improved as well as the labor costs are reduced by developing continuous rolling concave roll with the metal spraying process through optimizing such key control points as the chemical composition and production process of continuous rolling roll as well as comparing and analyzing its mechanical properties and microstructure before and after optimization, which provide the technical basis for developing large grooved roll and roll collar in future.

In this paper, the influences of super-thick material layer on sintering process indexes as well as productivity and quality of sinter based on the iron material configuration condition that high proportion of iron concentrate of sintering of Baotou Steel are mainly elaborated. The study results showed that the FeO content of sinter could be significantly reduced by increasing thickness of sintering material layer, the thickness of material layer was increased from 700 mm to 1 000 mm and the FeO content of sinter was decreased by 1.39 percentage points, or 14.2%. The solid fuel consumption of sintering could be effectively reduced, yield and drum strength of sinter could be improved by increasing the thickness of sintering material layer. In this paper, such indexes as the fuel consumption, yield, drum strength, RI and RDI_{+3.15 mm} of sinter tend to be increased then decreased with the thickness of material layer increases as well as they are optimal when the thickness of material layer is 800 mm, which shows that the suitable thickness of material layer is 800 mm with the iron material configuration condition of 20% Barun iron concentrate+20% Mongolian iron concentrate+60% imported iron ore powder.

The phase transition law of continuous cooling for SWRCH35KM test steel is tested with Gleeble-1500 thermal simulated test machine. The phase transition law of spheroidization of pearlite after final rolling is studied by the thermal simulation test of online spheroidization. There are transformations of ferrite and pearlite at different cooling rates as well as the characteristics of microstructure for ferrite change with the increase of cooling rates. When the cooling rate is below 2 ℃/s, the metallographic structure of SWRCH35KM test steel is ferrite and pearlite. With the cooling rate gradually increases, the acicular ferrite along with Widmanstatten structure appear continuously in the metallographic structure. Meanwhile, the ferrite is more refined than before and its volume fraction is also gradually reduced. Based on the phase transition law of microstructure and with thermal simulation test data of SWRCH35KM test steel, rolling and cooling will be strictly controlled in industrial production in order to obtain ideal metallographic structure, especially the controlled cooling mode of Stelmor cooling line to ensure to obtain fine ferrite and spheroidized pearlite.

In the paper, it is introduced the experimental study on heat treatment at a series of temperatures of 1 000~1 250 ℃ was carried out by taking the Fe-Mn-Al-C high manganese austenitic test steel as object of study. The surface oxide layer, microstructure and grain size of test steel were detected and analyzed separately. The results showed that the thickness of surface oxide layer increased with heating temperature increased, there was grain boundary oxidation when heating temperature was above 1 150 ℃; the grain size of test steel increased with heating temperature increased, there was mixed crystal at 1 150 ℃ and the grain size increased obviously at 1 250 ℃.

The process technology of “oxidation+chemical precipitation+coagulating sedimentation and heavy metal collector” is proposed through studying the treatment technology of thallium-containing desulfurization waste water as well as the optimal proportion meeting the requirements of removing thallium is determined by adjusting the concentration (set value) of oxidant (sodium hypochlorite), pH, polyaluminum chloride (PAC), heavy metal collector and polyacrylamide (PAM). The experimental results showed that the removal efficiency of thallium was 99.75% when the concentrations of oxidant (sodium hypochlorite), PAC, heavy metal collector and PAM were 1 500 mg/L, 200 mg/L, 1 300 mg/L, 4 mg/L respectively and pH value was 10, which could meet the requirements of discharge standard for thallium in desulfurization waste water.

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.

With the information construction of iron and steel enterprises, more and more data are generated in each link of logistics for crude fuel in iron and steel enterprises. The process of logistics for crude fuel relates to the safety of inventory for crude fuel and utilization ratio of storage space. In order to further improve the utilization of data, the real-time collection and monitoring of logistics data are particularly important. Therefore, the visual management of logistics process could intuitively show the connection and trend among information. In the paper, the applications of visual data management in logistics management of crude fuel in iron and steel enterprises are discussed by taking the construction of visualization system of logistics for crude fuel of Inner Mongolia Baotou Steel Union Co., Ltd. as an example.
