SOME PECULIARITIES OF THE PISTON CASTINGS PRODUCTION FOR HIGH-LOADED DIESEL ENGINES

The peculiarities of the pistons castings production for high-loaded diesel engines are shown

SOME TECHNOLOGICAL ASPECTS OF THE FORCER CASTINGS PRODUCTION

There are presented the applied technological approaches of hardening of the most loaded elements of piston and of providing of optimal heating terms of their operation, including using of inlays of Ni-resist cast iron under piston rings. The process of the preliminary heating of chill accessory is analyzed and recommendations on its realization are given

INCREASE OF WORKING LIFE OF PISTONS OF THE INTERNAL COMBUSTION ENGINES

The temperature regimes of piston of the internal combustion engines depending on the engine capacity are given. There is made overview of the existing ways of increase of working life of pistons of diesel engines, influence of structural components on high-temperature strength of aluminium alloys is analyzed. There is offered to study the possibility of increase of iron contents in piston alloys on the basis of microhardness intermetallic compounds

Technology and equipment for pistol casting

Description of main types of pistols, their construction peculiarities and materials used for their manufacture is given. Applied technologies of strengthening of most loaded pistol elements and creation of optimal thermal conditions of their operation are presented

THE METHOD OF SELF-FILLING OF THE MOLD AT PRODUCTION OF ALUMINIUM CASTINGS

The analysis of the ways of improving the quality and reduction of the first cost of the aluminum founding is presented. Different types of the gating systems with the analysis of their advantages and disadvantages are considered. It's shown that the method of founding by self-filling is being especially effective at receiving of long-distance casts. In this case the method of self-filling allows to increase considerably the yield of founding in comparison with the founding into the stationary forms
