与preheating相关的网络例句 [注：此内容来源于网络，仅供参考]

The hot air furnace is a kind of energy conservation type furnace, composed of burner, furnace chamber, mixing room, hot air outlet and outside jacket, the diluted air in the jacket has two functions, firstly, having insulation purpose: the air belongs to inert gas, it has good insulation function for furnace body, can reach to purpose to cool/protect inside lining and reduce its thickness of furnace chamber; secondly, having preheating function: the gas in the jacket is contacted with hige temperature furnace wall, and enters the mixing room after heat absorption, then to teach the purpose of preheating and energy conservation.

热风炉由燃烧器、炉膛、混合室、热风出口和外夹套构成，是一种节能型炉型，夹套中的稀释空气有两种作用，其一，保温作用：空气属惰性气体类，对炉体有良好的保温作用，达到冷却保护和减薄炉膛内衬的目的；其二，预热作用：气体在夹套中与高温炉壁相接触，吸热后进入混合室，达到了预热节能的目的。

It is shown that the effect of dynamic thermal tensioning by trailing intensive cooling is greatly influenced by the heat-dissipating conditions of the fixtures.Without uniform preheating it is difficult for trailing intensive cooling alone to create a saddle-shaped temperature field and the mechanism of reducing distortion is equivalent to the decrease of welding heat input. While combined with uniform preheating ,dynamic thermal tensioning comes into being to some degree and the effect of reducing distortion increases obviously.

研究表明，由随焊激冷造成的动态温差拉伸减小焊接变形的效果受夹具自身散热条件的影响较大：不采用整体预热时，难以造成马鞍形温度场，此时减小焊接变形的机理主要是焊接线能量的等效降低；采用整体预热后，能够造成一定程度的温差拉伸，减小焊接变形的效果明显提高。

Preheating shall also be applied to the tack welding, when the weldment requires preheating.

c 需要预热的焊件，定位焊时也应按规定进行预热。
