Kinetics of iron oxides reduction in a blast furnace
The mechanism of reduction of iron oxides in a blast furnace is shortly characterized on the basis of data [4, 11].
The essence of the method consists in reduction of test by carbon monoxide under the set temperature conditions and definition of extent of reduction by results of the chemical analysis of the initial and reduction test or loss of mass of oxygen at reduction.
Such design of a reactionary glass allows to avoid a stream limited mode at rather small expenses of gas and to neglect internal diffusion resistance when processing experimental data [10].
Then it is necessary to construct the schedule of dependence of the actual extent of the reduction calculated by results of measurement of loss of mass of reduction test from reduction time.

Firstly, the test data was discretizated and attribution reduced to get the reduction decision table.
Firstly, the test data is reduced through Rough Sets Theory to get the reduction decision table.
The 9 times test fault data is extracted in Table1, in which the data from the 1st time to the 7th time is diagnosis sample, the 8th time data is the normal sample, the 9th time data is the verified sample.
Through the equipment normal work interval, the above data can discretizated and the original decision table is gotten in Table1.
Then, contrasting it with the 9th test data, we can see they are consistent, so the above method is valid.

This reduction can be regarded as electron transfer followed by protonation.
The values obtained complemented by data taken from the literature [2,3] enabled the mean value of δ to be calculated to be 5.0 µm, under the particular stirring conditions employed. 4.
The reduction was found to occur at a half wave potential of -0.25 V vs.
Only a single reduction peak was observed, even though potentials down to -1.4 V vs.

Furthermore, a complete data acquisition system was utilized into the field tests, and all pressure values are measured and recorded by the system, which contributes to the analysis and optimization on the working performance of the oscillation tool with an amplifier.
ST004400 Pressure 0~70Bar Input 10V~24V Output 4~20mA Temperature (˚C) -40~+125 Precision (%) 0.5 Field test In order to monitor and measure the variation of pressure pulse with the pumped flow rate, there are totally 5 groups of flow rates are pumped into the oscillation tool with a fluidic amplifier, and all of the pressure pulse values are simultaneously obtained by the data acquisition system.
In the meantime, all the obtained pressure values are timely grasped and recorded by the data acquisition system while the pumped flow rate is ranging from 5L/s to 18L/s.
The pressure variation of monitored cross-section of the oscillation tool with pumped flow rate is obtained by data acquisition system, which directly implies the work performance and status of the friction reduction tool with a fluidic amplifier.

The material parameters σci and mb in the HB criterion are reduced directly in [3], and the MC parameters corresponding to the line tangent to the HB curve are reduced by the traditional MC strength reduction method [4].As for the HB criterion, the relationship between the HB and MC strength reduction factors are developed [5].
Fu [10] also derived the relationship between the material strength reduction factor incorporated in the HB yield function and the shear strength reduction factor in the p-q plane and exactly implement the non-linear shear strength reduction on the FLAC3D.
To verify our proposed reduction method, the FEM results were compared with the results of limit equilibrium methods: the Gle/Morgenstern-price method, the simplified Bishop method and the corrected Janbu method.
By analyzing the data in Table 3, influences of dilatancy angles on the factor of safety can be approximately described as a linear function, see Eq. 19
