摘要
Abstract
According to the solidification characteristics of HT300 hydraulic casting under EPC, a water-base coating for the hydraulic casting was prepared by using chromite fines, limestone and graphite powders as the refractory material. The optimum ingredient ratio of the coating was determined by orthogonal experiment. Ceramacore was selected as molding material. HT300 hydraulic castings were prepared by using high C and Si, recarburizing and resulfurization, and RECaBa compound inoculation. The experimental and applied results show that HT300 castings such as hydraulic pump bodies have smooth and clearly exterior surfaces, accurate dimensions; small holes such as oil passage are easy to clean; both mechanical properties and pressure-proof compactness have reached technical requirements.关键词
