The green transportation is the transportation characterized by energy conservation and reduction of exhaust emissions. It is the inevitable trend of future transport development to popularize green and low carbon means of transport as well as weed out and update or remould old vehicles and ships. At present, the internal combustion locomotive is still the main power of railway transportation in plant of Baotou Steel, which is with such disadvantages as high energy consumption and costs and more pollutions so as to be replaced by new energy locomotives in the near future. In the paper, it is briefly introduced the methods for transforming GK₁ type internal combustion locomotive into remote control gas-electric hybrid locomotive, focused on the process of applications in plant of Baotou Steel and analyzed the significances of energy conservation and environment protection, transportation efficiency and cost saving for reformed gas-electric hybrid locomotive through practices of applications.

The methods for improving the measuring accuracy of resistance strain type rolling force dynamometer are analyzed from such two aspects as sensor and secondary instrument respectively. The manufacturing accuracy and on-site installation conditions of sensor are the main factors affecting accuracy. The voltage-multiplying of excitation power supply and six-wire bridge circuit are helpful to reduce the errors caused by excitation power supply. The ratio calibration of sensor could solve the problem of measurement errors caused by calibration errors, which is very convenient to apply in the steel rolling field. The modified formulas of calibration ratios are obtained through mathematical derivation considering the problem of cable between the sensor and secondary instrument in the steel rolling field.

In this paper, it is introduced a design of calculating and recording the deviations of predicted and actual rolling forces for all stands of CSP hot continuous rolling mill by the VBA language environment. The deviations of predicted and actual rolling forces for all stands in a certain range are calculated and with classified statistic based on various rolling parameters in the VBA language environment so that the analysis time is greatly shortened and errors of manual computation are reduced as well as the effects of various rolling parameters and specifications on accuracy of predicted rolling forces could be reflected intuitively. Moreover, the effects of various rolling parameters on accuracy of predicted rolling forces are illustrated through analysis combining with the practical examples, which is with great reference significances for adjusting the corresponding secondary parameters for rolling mill.

In the information economy era, the drawbacks of traditional operation and management models for separation of finance and business have become more prominent. The problem that how to overcome the delayed decision-making and inner control of enterprise caused by lag of corporate financial information due to the “information isolated island” has become the urgent problem for many large enterprises. In the paper, it is described the organic integration of finance and business process is prompted through sorting out business processes so as to effectively improve the management level of large enterprises, ensure that financial data could reflect the whole production management process accurately in real time and achieve the effect of dynamic monitoring of important links in the process in detail. Moreover, the three main processes in enterprise operations, that is the business processes, financial accounting process and management process are with interworking and coordination.

The physical archives are archives in physical forms with important preservation significance and collection value formed in various work activities and outside communications of colleges and universities. They are the important components of archives and important supplement to documentary archives of colleges and universities. They concentrate the essence of school development as well as they are the powerful proof of historical development of colleges and universities and the crystallization of practical experiences and wisdom for teachers and students. They are with relatively obvious characteristics and are different from the traditional archives so that they are with important significances and values. In this paper, the current situation of physical archives in colleges and universities is analyzed starting from the work experiences of managing them as well as the management of them is discussed from such aspects as collection, arrangement and utilization of them. Moreover, their outlook is proposed.

In this paper, the boron in low-alloy steel is determined with ICP-AES and multispectral fitting analysis technology. The analytical spectral lines of elements, interference and correction of coexistence elements as well as detection limits are studied by the condition experiments with instrument. The measuring range is determined to be 0.001%~0.100%. With the method, samples are dissolved with the mixed acid of hydrochloric acid and nitric acid, then they are directly determined with instrument. As a result, a simple and rapid analysis method for determining boron content in low-alloy steel is established, which is with good accuracy and precision.

The 5th generation American Morgan technology was introduced in the early 1990s for a production line of high speed wire rod and its design capacity was 0.38 million tons. With the constant improvement of production technology and efficiency for the deep processing industry of wire rod, the requirements of dimensional accuracy, surface quality and mechanical properties for wire products in the market are higher. In order to satisfy the market changes and improve product competitiveness, the size reducing mill is added in the production line of high speed wire rod. In the paper, it is introduced the construction transformations of such types of equipment as mechanical, electrical and power as well as the roll gaps of finishing rolling unit and size reducing mill are redesigned. Moreover, the R values of each stand are given as well as different accident types and solutions after the mill put into production are summarized.

The mineral species that have been found in Bayan Obo ore deposit are sorted and recorded based on the list of mineral species in Bayan Obo mining area in Mining and Metallurgical Technology of Baiyuneboite as well as the research achievements of minerals of Bayan Obo are collected combining with such documents as Mineralogy of Bayan Obo. The results showed that there were 172 types of minerals in the list of mineral species in Mining and Metallurgical Technology of Baiyuneboite after correct obvious errors, the minerals reached 191 types by supplementing the minerals that were not recorded in Mineralogy of Bayan Obo; a total of 209 types of minerals have been found in Bayan Obo ore deposit so far, together with the newly found minerals and new minerals.

The stock of medium-lean oxidized ore in Bayan Obo is huge as well as its degree of oxidation and impurity content are high. Among them, iron and rare earth are the main recovered components. The grade of iron is 28.74%, content of FeO is 1.99% and grade of rare earth is 5.45%. The iron in the ore mainly exists in forms of hematite and limonite and magnetic iron as well as the distribution ratios are 48.54% and 43.84% respectively. The qualified iron concentrate with grade of iron concentrate of 66.07% and gross recovery of iron of 87.47% is obtained by studying the ore properties of medium-lean oxidized ore in Bayan Obo as well as exploring and recycling its iron resource with the process of “preconcentration-hydrogen-based mineral phase transformation-stage grinding-stage magnetic separation”. This method is beneficial to the full utilization of iron resources and improving the utilization rate of mine resources.

It is considered that there is no direct relation among the bubble coke rate for large capacity coke oven and the strength, ash content as well as scurf resistance M₁₀ of coke after reaction while there is certain correlation between it and coking time through their data analysis. As a result, it could not be as the evaluation index for coke quality.
