Development of a centralized system for separating lubrication supply on press-forms of JSC “Rifar” casting complexes

Abstract

The company "Rifar" is a domestic manufacturer of a new series of bimetallic and aluminum sector radiators of high quality. Production of bimetallic heating radiators is carried out using a hydraulic press. For the least adhesion of the alloy to the molds walls (especially when casting aluminum) the lubrication of the molds with a separating lubricant is used to reduce the wear of molds and refills on the blanks. Currently, the lubrication of the molds is used. Separating lubricant for the molds is taken from the individual intermediate tank standing near each foundry complex. In this case, the lubricant is filled once, and it is used throughout the shift. After that, the tank with the help of forklifts is sent to refueling. To increase the operational reliability and ease of maintenance of foundry complexes, it is proposed to replace the individual supply of separating lubricant to the molds of foundry complexes with a centralized supply system. As a result of development of a system for the centralized supply of separating lubricant to casting complexes molds, it was possible to simplify the lubricant supply scheme, to reduce fuel costs and maintenance complexity. Replacing the individual supply of the separating lubricant to the molds of the casting complexes with the centralized supply system improves the reliability of separating lubricant supply to such complexes molds. Calculations showed that implementation of design solutions does not require large capital expenditures, and as a result of the implementation of the proposed measures, the production cost will decrease by 0.02 %; the payback period of the proposed investment project does not exceed 1 month.
