In this paper are presented investigations of the influence of working conditions to the mechanical properties of the bulldozer track pads used for the slag removal in the steel plant. Crawler vehicles are generally used as earth moving equipment. In our case bulldozer is used for slag removal from the floor in steel plant. So in this case pretty different working conditions are present i.e. elevated temperature over to 400 0 C and quite different mediamedia i.e. hot slag. To understand better

... orking conditions and their influence to the properties of track pads different investigations were performed. As first, measuring track pads wearing off and measuring of slag and track pad temperature. Chemical composition of the slag and track pad was determined too. Metallographic investigations comprise determination of nonmetallic inclusions and microstructure. Mechanical invetigations consist of hardness measurements, and tensile testing. Performed investigation confirm that material of the track pad is good for usual working condition but for slag removal at elevated temperature intensive wearing of pads happen.
