§ 2.3

　　Analyze: both the output and the coefficient of sinter increase, the daily output increase 129t. The waste of electricity decrease 1.41kwh/t. the quality of sinter also improve.

3 Some problems in reconstruction

　　§ 3.1 、 Because of the reconstruction of seal, the lubricating system of sinter has reconstructed, but the former lubricating system reserve the traditional lubricating system, so the different lubricating point has different position, different distance from oil pump and different resistance; Maybe there is not enough oil; some has more; some has less, even has not any; if under the situation, it can't lubricate the fixed slideway well; some times there is dry rub between the trolley sliding board and sinter fixed slideway in some part; it not only decrease the seal, but also decrease the life of the sliding board; So we reconstruction the sinter lubricating system with intelligent lubricating technology; and then we get those character: firstly, offering oil point by point, that is to say, we supply oil according to procedure and order. The lubricating pump just offer oil for a point in unit time; secondly, checking point by point, in other word, checking the shifting signal in pipeline, and then reflecting the situation of lubricating character; thirdly, judging the trouble intelligently can judge the trouble of every lubricating point and lubricating component.

　　At present, it has been used in No.3 sinter of No.1 workshop, it has good effect and get good lubricant effect; we will reconstruct the rest sinters in No.1 workshop.

　　§ 3.2 、 We should consider every detail in the process of reconstruction, we find No.2 sinter end seal board fretted seriously when the device run. After examination, we find that the main reason, the material can't go easily after pressurizing the board; and then the finished products was blocked on the seal board. The grain of sinter rub, erode the seal board for the long time, and then effect the life of the seal board. We will draw a lesson in the following reconstruction, and then solve the problem.

　　Besides, we find that the trolley board was crashed while the seal device run; the reason of the phenomenon is old trolley, some trolley has been fretted about 1m; although we have considered the problem before we design, but because of the big abrasion, it also make some trolley sliding board longer then the trolley body, under the situation, it can make few sliding board crashed while the trolley pass the bending road. Therefore, we demand the length of the sliding board longer than the trolley body about 1mm when we process the trolley sliding board.

　　§ 3.3 、 the seal of sinter is a whole system, in daily work, we should strengthen the daily operation management, for example, strengthen the end discharge the ash valve; Strengthen examination to the slideway lubricant; adjust the sinter's deviation; avoid leaking wind. It not only decrease leaking wind, but also guarantee the seal device that can run for long time, and then make the sinter leak air scarcely in long time.

4 Conclusion

　　§ 4.1 The sinter leaking wind rate will decrease below 40 ％ according to the technical reconstruction of sinter seal; the system of sinter's leaking wind rate reach below 45%. That is to say, it is effective to decreasing the leaking wind rate of sinter that the reconstruction to trolley slideway, fix slideway and head and end seal

　　§ 4.2 It improve the output and save the energy according to technical reconstruction of the sinter seal; the output of sinter improve about 4%; at the same time, because the effective wind accelerate, the consume of electricity decrease about 1kwh per ton; the quality of sinter is also improved. The economic benefit is more obvious.
