Paddle arms |
Of the most important qualitative specifications of this part is its lifetime because of difficult and time-consuming replacement of parts and high cost of dormancy in the civil projects. In this regard, factors influencing on the lifetime of a part have been identified according to the examinations and analyses and categorized in two following groups:
- Raw materials and alloy used in casting a part
- Base of materials used in asphalt production (application environment of a part)
Regarding the raw materials and alloy used, this company relying on its practical and scientific experience has been able to identify alloys which increase the resistance of parts in high heating and abrasive environments by analysis of materials. In cases which the base of used materials is also hard and siliceous, alloy is determined so that resistance and lifetime of a part against the heating and abrasion are more than the same samples.

Elevator roller |
Due to its application environments including the heating and abrasion ones, this part usually has high consumption factor among the parts. Hence, it is required to improve quality of the part due to the criticality of the part in terms of the complexity in its replacement and time-consuming. For this reason, type of the part’s alloy was improved based on the feedback of part’s performance by customers and their analysis that it increased lifetime of the part and, subsequently, decreased replacement and purchase costs of the part for customers. |
