Improving the performance of high-strength steel castings by specialized cooling

Resumo

The influence of microcooling and external cooling on the structure and mechanical properties of moderately alloyed high-strength special-purpose steel and also on the morphology of its nonmetallic inclusions is investigated. The properties of castings obtained in different molds and in different conditions are compared. The influence of hybrid (external and internal) modification of the casting process on the quality of heavy housing castings is investigated.
