摘要

一般来说,影响公司生产力的主要问题之一是其技术设备的部件变质为废物。从这个意义上说,研究这些部件在其使用寿命期间的表面硬度的行为是至关重要的,以便能够推荐一种有效的结构,至于材料和处理的选择。本文研究了输运辊在开采过程中所经历的表面硬度变化。确定了温度、力、转数和冷却方式对AISI 1045钢的硬度的综合影响,以及层压和温度对硬度的影响。采用便携式316型硬度测量仪,测量范围为20 ~ 65 HRC,偏差为1.5点,对12个轧辊在开采设定前后的表面硬度进行了测定,保证了95%的信任水平的正态性。结果表明:开发前轧辊的硬度为47.5 HRC,开发后轧辊的硬度为41.7 HRC。另外,made variance的分析是指在开采过程中,表面硬度值在设定前与设定后存在显著差异,说明有必要对造成这种差异的原因进行细致的分析,以提高工艺质量。关键词:硬度;辊;生产力;温度;正常

VARIACIÓN DE LA DUREZA SUPERFICIAL DE LOS RODILLOS RADIALES DE TRANSPORTADORES YACOBI.
One of the medullary problems that has affected the productivity of the companies in general, is the deterioration of the pieces of their technological equipment for waste. In such a sense, the study of the behavior of the superficial hardness of these components during its useful life is of vital importance, to be able to recommend an efficient structure, as for the material and treatment to select. In this work was carried out a study on the variation of the superficial hardness that experiences the radial rollers of transporters yacobi during their period of exploitation. The influence was determined that have about the hardness the combined effect of the temperature, the force, the number of revolutions, and the cooling regime in the steel AISI 1045, laminate and temperate. The determination the superficial hardness of 12 rollers was made before and after the setting in exploitation with an instrument to measure hardness portable model 316 with range of mensuration of 20 - 65 HRC and appreciation 1,5 points, assuring the condition of normality for a level of trust of 95%. The results obtained indicate that the hardness of the rollers is before 47,5 HRC and 41,67 HRC and after the exploitation respectively. Also, the analysis of made variance refers that significant difference exists before among the values of the superficial hardness and after the setting in exploitation, what indicated the necessity to carry out a meticulous analysis of the causes that are causing this variation to improve the quality of the process.  Key words: Hardness; rollers; productivity; temperature; normality
