3 In the design, we conducted a difficult research to address the uneven heating and billet billet black print issues. (1) We move the cylinder to the level of the trip is designed to 320mm, the furnace is set to place the billet rack spacing 300mm, so the blank after the placement of each advance is not right on the rack of the groove, but fall In the alveolar slope, so that their rolling stock to the groove. Every step on the rolling stock once, so that makes it more uniform throughout the heating process. The improvements to solve the axles in uneven heating of the furnace, deformation problems, has very important significance. (2) using high heat. See bottom trajectory map in front of activities, that ③ bit heated. Previous design in ① bit heated,mulberry outlet, billet heating after the rise again, forward,ralph lauren danmark, horizontal beam on the rise, the suction from the water seal at the cold knife, black mark will appear blank. Heated to high, that rise in activity at the end, forward after heating. In other words, each blank to complete a cycle of action need to step 9.23 points, so it stays in ③ bit of time about 8 minutes. This time at a high seal knife, although cold air inhalation, but the billet in the heating state, the black will not print. (3) To prevent smoking cold, (the transfer p. 20) · 2O · Heavy Industry 2002No. 1 degree and the ratio of tangential velocity is constant, that is, (dp / dt) / p (d0/dt) = K,uggs nederland, which can be obtained by working bodies of the push to enhance the speed and the speed ratio]. The advantage is to describe the trajectory of a simple mathematical model,uggs online bestellen, the structure of machinery and equipment is simple, easy to control, easy to implement in engineering. For mining by the curve, through the arc S, tip the bucket on the track average speed: 1, an S / t eleven (1.11 ~ 0.93) m / s straight-line tap, the average speed of : j1, = l / t West (1.25 ~ 1) m / s at the track, the weight of the bucket tip speed ratio can be written as: blood R == dO = tan0tanet1 (1o) curve shown in Figure 2 Figure 2 faster than the curve from the curve to see, the basic linear change, the rate of change is basically the same, approximately constant, so easy to control, the project is also easy to operate. 3 Conclusion As with excavator digging the same kind of soil (hard rock), cutting the thickness of that same; take on the style to take the next digging force w-type digging force w: ratio: Q: == 321046 ...) W2w × indicating the ceremony to take mining resistance than the next to take the resistance type tap from the above analysis the following conclusions can be drawn: (1) after the soil excavation blasting, excavation on the way to better take style (2) To improve the fill factor should be taken mixed mining , that is excavated along the appropriate stockpile ramp (3) should be vigorously vibrating mining research.

Conclusion With the development of national economy, rail transport will become increasingly busy, train axis will have great market demand. Therefore, the development of train-axis lines have broad prospects for the train shaft production line design and manufacturing success for China's railway industry has laid a foundation, to alleviate the domestic situation of dependence into the El axle made some contribution.
