In the paper, a new understanding of the benchmarking management for enterprises is put forward by further digging the root causes of problems in benchmarking management of enterprises, and the value and significance of reducing the cost of production through the implementation of benchmarking management are expounded. Through the perfect combination of benchmarking management, project management and lean management, the reasonable control of sintering production cost is realized.

Based on the analysis of the production status of steelmaking in Baotou Steel and the characteristics of ERP system, the corresponding design of steelmaking operation management system of Baotou Steel is made. According to the process of steelmaking, the system modules are divided from the flow backward station, desulfurization, converter, refining, casting machine and material number maintenance; according to the relationship between the data source and data dropping, the relationship between steelmaking operation management system and other ERP subsystems is designed to ensure the accuracy of data source and data dropping.

Based on the analysis of implementation principles and characteristics of two-dimensional code anti-counterfeiting technology, two-dimensional code anti-counterfeiting system applied to common mobile devices is designed and developed based on the actual needs of different products in the process of product circulation. The system is applied to product anti-counterfeiting, with low cost, high efficiency and can be separated from the cable network to achieve the purpose of anti-counterfeit verification. The system can greatly improve the ability of product anti-counterfeiting, effectively combat the overflow of counterfeit products, and is very important for maintaining Baotou Steel's product image, purifying market order and enhancing product competitiveness.

In the paper, the solution to the contradiction between prominent problems of traditional personnel management in Baotou Steel, such as inconsistent information, the complicated business processes, the low work efficiency, and the growing situation of enterprises is made. Use the current mainstream Java language and MVC design pattern for design. Personnel management is a part of ERP human resource management, and ultimately will achieve the isolation of information from all previous secondary units and asymmetric personnel information are transformed into unified information, staff information updated in time. It is organized by the Organization Department of personnel management, realizing the first level management of the company.

The continuity equation and the Euler equation are the core contents of the momentum transfer. The derivation process has always been the focus and difficulty in teaching and students generally reflect it is difficult to understand in the past. In order to make students better understand and master the derivation process of the continuity equation and Euler equation, in the paper, it is discussed the topic teaching method and deduced the continuity equation and Euler equation of fluid flow, and some understanding and experience in topic teaching method for derivation of the continuity equation and Euler equation are shared, providing the reference for teaching of momentum transfer theory.

In the important period of country to promote supply-side structural reform and steel industry to achieve transformation and upgrading, combined with the current situation of China's iron and steel industry, the difficulties and opportunities are analyzed, and the way out for the development of China's iron and steel industry under the new situation of economic development is discussed. It is pointed out that innovation drives the transformation and development of iron and steel industry, and adjusting the structure and realizing the green manufacturing of iron and steel industry are imperative.

The work of dry dedusting instead of wet dedusting for No. 1 and No. 2 converter in CSP Plant of Baotou Steel has been completed in 2006. In view of the problems existed in equipment of 210t converter dry dedusting system, such as failure, failure of multiple parts and the low efficiency of equipment operation and so on, after a long period of exploration, measures to reduce the equipment failure and equipment operation rules have been found out, and some equipment have been effectively improved and transformed to reduce the equipment accident time and improve the efficiency of dust collector.

In the paper, usage amount ratio of desulfurizer and stirring time of desulfurization are studied in the process of KR desulfurization for pretreatment of hot metal, and on the basis of reducing 30% desulfurizer addition amount in the original design, while extending the stirring time 3~6 min, which can improve the utilization of desulfurizer, achieve desulfurization with low cost, thereby reducing the cost of raw material consumption.

In the paper, it is introduced the use scheme of self-produced saturated steam from 210 t converter in Sheet Plant of Baotou Steel and the steam is used for RH vacuum pumping, EC spray gun of dry dedusting, deaerator water tank heating and damp down of opening for oxygen core lance and so on, and the corresponding measures are adopted to reduce the steam release rate of converter, reduce the waste of energy and the consumption of external superheated steam, realize the gradient utilization of energy and save energy and reduce consumption, achieving obvious economic benefits.

Through the analysis of w (FeO) change in top slag of silicon steel, it is concluded that the converter tapping of silicon steel is not completely deoxidized, which leads to the transmission of oxygen from steel to slag, and it is the main reason for poor effect in top slag modification of steel ladle in converter process. Through two-step top slag modification, the one is top slag modification of steel ladle in converter process, the other one is top slag modification of steel ladle in RH process, and taking the technical measure of alloying of manganese before RH decarburization, the w (FeO) in RH top slag of steel ladle for ultra-low carbon steel can be reduced to less than 5%, and the w (MnO) shall be controlled at about 4%, and the w [O] _T in tundish molten steel shall be controlled below 20 × 10^-6, through which the cleanliness of ultra-low carbon steel will be remarkably improved.
