The materials of crankshaft mainly use QT900-2 and QT800-2 high-strength rare earth, magnesium, copper, molybdenum, spherulitic iron, and auxiliary with forging steel crankshaft.

公司产品以 QT900-2、 QT800-2高强度稀土镁铜钼球墨铸铁的曲轴为主，锻钢曲轴为辅。

The test results indicate that T2 Cu/2A50 Al alloy must first be done by blacksmith welding, and then heated between 515℃ and 525℃ for 180 min, the sample pressure is offered by heating and insulation in the process through special fixture, the joints of T2Cu/2A50Al alloy with metallurgy bond can be obtained, and there is obvious welding seam in the interface.

试验结果表明，T2铜／2A50铝合金，采用先锻接，后加热到515~525℃之间，保温180 min，并在加热和保温过程中通过特殊的夹具提供给试样压力，能得到冶金结合的T2铜／2A50铝合金接头，接头界面处出现了明显的焊缝。

T2 Cu/2A50 Al alloy was bonded by blacksmith diffusion welding technology.

采用锻接扩散焊法进行了T2铜／2A50铝合金异种材料的焊接。

And a relative preparation is characterized in that according to mol ratio (0.8-0.975):(1.8-1.95):(0.010-0.15):(0.010-0.15) to prepare and mix Mg powder, B powder, C nanometer powder, and SiC nanometer powder uniformly to be filled into an iron tube or iron-copper composite tube to be sealed, rotationally forges, draws and rolls to obtain MgB2 superconductive material containing C and SiC nanometer powder, or tablets the raw powder mixed uniformly via a tablet press, to obtain MgB2 superconductive block containing C and SiC nanometer powder, arranges obtained band or block in a vacuum furnace, vacuums and fills argon gas, keeps temperature for 0.2-3h at 600-1200DEG C, and obtains MgB2 superconductive material containing C nanometer powder and SiC nanometer powder.

制备这种MgB 2 超导材料的方法，其特征在于，将Mg粉，B粉，C纳米粉，SiC纳米粉按照摩尔比(0.8-0.975)∶(1.8-1.95)∶(0.010-0.15)∶(0.010-0.15)配制并混合均匀，装入铁管或铁铜复合管中密封后，按顺序先后进行旋锻、拉拔、轧制，得到含C和SiC纳米粉的MgB 2 超导线材；或者将混合均匀的原料粉用压片机进行压片，得到含C和SiC纳米粉的MgB 2 超导块材；将得到的线带材或块材放置真空炉中，抽真空后充入氩气，在600℃-1200℃保温0.2-3小时，最终得到含有C纳米粉和SiC纳米粉的MgB 2 超导材料。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
