Perawatan dan pemeriksaan pada pantograf kereta PT MRT Jakarta dilakukan setiap satu bulanan. Guna menjaga agar sarana kereta selalu layak operasi, perlu adanya acuan waktu penggantian main contact strip. Tebal minimum yang dibolehkan untuk main contact strip pada saat ini adalah 5 mm. Sedangkan tebal main contact strip baru adalah 17 mm. Tujuan dari penelitian ini adalah untuk mengetahui perbedaan tingkat keausan yang akan terjadi sesuai dengan kondisi yang ada di lapangan. Dilakukannya uji laju keausan menggunakan metode Ogoshi dengan varian kecepetan dan varian jarak luncur. Dari hasil penelitian yang dilakukan dapat disimpulkan bahwa semakin besar kecepatan maka tingkat keausan semakin tinggi. Semakin jauh jarak luncur maka semakin kecil tingkat keasusan. Laju keausan yang terjadi dilapangan berbeda dengan laju keausan di Lab.

Control And Management

ncrease of requirements to quality of the flat-rolled steel causes the appearance of new methods and improvement of the well-known approaches to improving the geometry of thin-gage rolled steels. On modern rolling mills, control and management of the strips cross-section is carried out by a profile and flatness control system (PFC). The main channel of the influence of such systems on the geometric parameters of the rolled steel is the axial shifting of S-shaped working rolls in CVC (Continuous Variable Crown) mills. The performance of the PFC is determined by the correct choice of the initial (machining) profile of the working rolls. The paper discusses the way to improve the methodology of grinding S-shaped working rolls by taking into account the stresses, arising in the zone of contact strip with rolls, the elastic deformation of roll system, thermal deformations, arising from the contact with the hot strip and wear of the working layer of the rolls during the campaign. The developed mathematical model of stress-deformed state allows you to determine the places with the highest stresses in the zone of contact strip with working rolls and adjust the initial profile of the rolls to ensure uniformity of extracts of a strip in width with regard to shifting rolls in the axial direction. The mathematical model of the thermal condition of S-shaped rolls, which allows to predict the change of the rolls thermal profile, gives the possibility to create the algorithm for the grinding of the working rolls in hot condition and increase the accuracy of performance of their machining profile.
