機床床身也是由高頻感應加熱爐淬火完成的

機床床身鑄件的品質好壞的評判標准包括：機床的耐磨性和消震性，工藝性能。提高機床床身的鑄件的內在質量和組織性能，必須要經過高頻感應加熱設備的熱處理。經過高頻感應加熱爐的工藝處理，能夠提高鑄鐵的耐磨性，同樣因爲石墨的存在消震性也會改善。

機床的精度要求是極高的，機床是制造金屬産品的一種設備，所以又稱“工具機”。床身是機床精度要求很高的帶有導軌的大型基礎部件，用于支撐、連接車床的各個部件，主要起到抗震、減震、抗壓等作用，是機床非常重要的成分。

那为什么说为什么机床床身铸件必须要经过高頻感應加熱爐的热处理？

首先床身鑄件是金屬組成的，要得到良好的性能和功能，改善床身鑄鐵的內在品質至關重要，床身鑄件要有抗壓耐磨的特性，否則就不能持久的工作。
使用高頻感應加熱爐对床身铸件进行热处理，主要是改变铸件本身的显微组织和结构，改变其表面的化学成分，从而提高床身铸件的物理性能、化学性能和力学性能。
高頻感應加熱爐对铸件的热处理主要是消除铸件的内应力以及改善切削工艺，主要的热处理包括消除铸件白口退火和应力退火以及表面淬火。

下面主要談談如果對機床床身鑄件進行高頻感應加熱設備的表面淬火處理：
通過高頻感應加熱設備對機床鑄件的快速加熱處理，是機床鑄件很快達到淬火溫度，熱量到達鑄件心部之前進行冷卻，這樣可以讓機床鑄件的表面獲得高硬度和高耐磨性。

AN OLD SETTLER. AN OLD SETTLER. "Of course, you know where the Dutchman is to be found?" "I am afraid I was as foolish as that," Bruce said, with a faint smile. "That sort of people seem to know when one is under the weather. And there was one very plausible fellow who sent me a confidential letter. I fell into the trap, and if I can't find ￡500 tomorrow I am ruined." "I believe that it is my duty to take that task upon me, assisted by some well-known burgesses, who have undertaken to stand by me. 72 When people in Parisian society thought of the country, they thought of lambs with ribbons round their necks, shepherdesses in fanciful costumes with long crooks, or a “rosière” kneeling before the family and friends of the seigneur to be crowned with flowers and presented with a rose as the reward of virtue, in the presence of an admiring crowd of villagers; of conventional gardens, clipped trees, and artificial ruins; but wild, picturesque mountain scenery was their abhorrence. She must have tossed the life preserver from the stern. Nothing else explained its employment. From the air, to an observer who had no idea that his craft had been used, all should seem natural, Larry decided as he and Dick, with Sandy’s discarded garments, and with the caretaker ruefully grumbling, chose a place of concealment. She smiled. "The chances that she will marry are excellent." Arizona had its full share of murder and sudden death. But New Mexico had more than that. Spring passed on there, with warmth for the snow-wrapped mountains, and blistering heat for the dead plains, and her way was marked with lifeless and mutilated forms. Chapter 24 "Deer Bat: Got yore $100 all right, but doant send by that "Rose, marry me." "Unhappy woman!" said the monk, in a tone that seemed to encourage her to proceed—"what would you of me?" "Roland de Boteler, do you intend to submit?—but you have not a mother's feelings!" "These knaves wish to carry things with a strong hand, my liege," said the Earl of Oxford, bending his knee as he presented the scroll. HoME 手机看片1204免费人一级ENTER NUMBET 002www.bj-net.com.cn
