quenching time

The results show that the hardness of bearing roller is lower than the required because no martensite is formed when the quenching time is 55 min and the quenchant is the oil or UNCON ( 25w%).

结果表明：淬火时间为55min，淬火介质为油或UNCON（25%）时，支承辊不能得到马氏体而硬度降低；

The experimental results indicate that during 30-120 min, with increasing the isothermal quenching time, the content and carbon content of retained austenite increased to a max value at 60 min, then decreased.

试验结果表明，在30～120min等温淬火时间范围内，随着等温淬火时间的延长，残余奥氏体量及其含碳量逐渐增加，60min时出现峰值，然后逐渐降低；

At the same tempering time and tempering temperature, as the quenching temperature rise, the corrosion resistance of the samples decreased. But under quenched at 930 ° C for 30 minutes, the best comprehensive performance can been obtained.

随着淬火温度的增加，相同的回火温度与回火时间的试样的力学性能在930°C淬火时达到最高，而耐蚀性能则不断降低。

Moreover, for the second case, a natural continuation problem after the quenching time for the non-simultaneous quenching is found, then we obtain that the solution of this equation is incomplete quenching.

The time of maximum fluorescent quenching and the half time of fluorescent quenching were significantly prolonged ( P < 0.01).

最大荧光淬灭时间和半数荧光淬灭时间非常显著延长（P＜0.01）。

A better quenching effect is obtained when the temperature increases; and the quenching result is also influenced by the mixing time of fluorescence quenching agent and the pulp.

结果表明，浆料温度及荧光消除剂与浆料的混合作用时间对荧光消除效果有较大影响。

The significant effect on the mechanical properties is quenching temperature, the effects of tempering time come second and the effects of tempering temperature wast' n obvious.

淬火温度对其力学性能有显著影响，回火时间次之，回火温度影响不显著。

According to the requirement of hardness on roller surface, the quenching temperature of HSS containing high carbon and high vanadium is 950~ 1100 ℃, and the tempering temperature is 530~ 550 ℃, tempering treatment one time can meet the requirement.

根据轧辊辊面硬度要求，高碳高钒高速钢的淬火温度为950～1100℃，回火温度为530～550℃，一次回火即可。

Modifications of the term quenching include direct quenching, fog quenching, hot quenching, interrupted quenching selective quenching, spray quenching, and time quenching.

淬火包括直接淬火、喷雾淬火、热淬火、分级淬火、局部淬火、喷射淬火和限时淬火。

It is noted that the quenching process of the current lead can be divided into two stages. The operating time for protecting the quenching current lead should be smaller than the first stage time.

仿真结果分析表明：电流引线失超过程可分为两个阶段，电流引线的失超保护动作时间应小于第一阶段时间。

At the same quenching temperature, as the tempering time extended and tempering temperature rise, the strength of the sample decreased, plasticity, impact toughness and corrosion resistance increased.

随着回火温度和回火时间的增加，相同淬火温度下试样的强度下降，塑性、冲击韧性和耐腐蚀性均提高。
