预热

Base on the weldability tests , the repair welding procedures of weari-resistant cast steel (abrasion-plates) have been made up , The results show that satisfying repair welding quality can be attained with such welding conditions as the low hydrogenous alkalescent welding rod , preheating and slow cooling , strictly maint.

通过对其焊接性能的试验研究，制定了该类铸钢件的补焊工艺：低氢型碱性焊条，预热与缓冷相结合的工艺措施，严格控制层间温度(250～300℃)及焊接工艺规范，可获得满意的修复质量。

BOTH LINES CROSS EACH OTHER AND CONTINUE DRAWING YOUR VERTICAL LINE UP TO THE BOTTOM HORIZONTAL LINE, YOU NOW OBTAIN AN IMAGINARY POINT OF INTERSECTION, AND THE POINT OF INTERSECTION INDICATES THE PERFECT PREHEATING TEMPERATURE FOR EPOCAST 36 UNDER CURRENT CONDITION.

5.6-4 两线相交并将垂直线持续延伸到表格底部水平线并得一交点，该点即为与当前环境下预热环氧树脂时所需的温度

Use an immersion heater with plastic containers.

用铁容器可以先预热油，再内加热。

Meanwhile, preheat heterogeneity can inactivate enzymes and to prevent the floating fat products.

同时，预热可以钝化酶并防止均质后的产品中脂肪上浮。

So It induction heating is a feasible method to use.

因此采用感应方式来预热加热板是一种可行的方法。

The preheating temperature of ingot is 100~120℃.

其中铸锭预热温度为100~120℃。

According to this require, it is necessary that we mount an aluminium ingot preheating furnace.

按照这一要求，我们公司有必要上一台铝锭预热炉。

We should use the tempilstick to check the temperature for the preheating of the interlamination away from the soldering seam less than 75mm.

预热和层间温度都应用测温笔在离开焊缝不小于75mm 的地方进行检查。

In addition, steam piping and steam transmission equipment used to steam temperature warming in the process from the initial cryogenic condensation water to rapidly discharge equipment in a short period of time to achieve normal operation, it is important to increase productivity, particularly intermittent production occasions, as a shortened pre - thermal time, it shortened the period of time, the increase in the number of treatment and eventually increase production.

此外，在蒸汽输送管路和蒸汽使用设备升温达到蒸汽温度的过程中，所产生的初期低温凝结水也要迅速排出，使设备在短时间内实现正常运转，这是提高生产效率的重要条件，特别是间歇生产的场合，由于缩短了预热时间，也就缩短了每次的作业时间，由于增加了处理次数，最终可增加产量。

In addition, transmission lines and steam in the steam using equipment to steam temperature heating process, the condensate produced by the initial low temperature and quickly discharged to the normal operation of equipment in the short period of time, this is an important condition for improving production efficiency, in particular, intermittent FORGED STEEL VALVES production of the occasion, because shortened warm-up time, thus shortening the time each operation, the addition of the processing times, ultimately, increased productivity.

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
