【 摘 要 】

The paper presents the critical technology for obtaining of the lamellar graphite grey cast iron castings (Supporting roll type). Are presented the stages of achievement of the mould and the elaboration technology of the liquid alloy. A view to improving the qualitative characteristics of the castings and reducing the defects due to achievement of moulds it is necessary to use the antiadherence paints for moulds and cores. From the point of view of the cost the antiadherence paints belong to the expensive material category. But these expenses are done with their acquisition are amortized into account of improving the commercial aspect of the castings and shortening of the cleaning-finishing operations. Due to increase the resistance of the moulds and cores which they apply it is possible to decrease the machining allowance.
