FIELD: manufacture of cast products in the form of one part with controlled non-uniform graphite structure. SUBSTANCE: method comprises steps of preparing melt iron with compact graphite, pouring melt iron to casting mold whose walls (or core surface) is coated by reactive material; sampling melt iron and placing samples into sampler. Method provides heat balance between sampler and sample. EFFECT: possibility of using cast iron with compact graphite for making machine parts having not only high strength but also good capability to casting and mechanical working, high heat conductivity. 4 dwg, 1 ex
