Improvement of internal combustion engine valve seats casting technology
Abstract
With а view to improve operation and technological properties of engine valve seats, composition of chromium cast iron has been optimized and a mathematical model of castings hardening has been worked out which allows to calculate cross sectional area of a feeder depending on the alloy temperature, form temperature and hydrostatic head. Optimization of technological process secured stability of valve properties and eliminated porosity spoilage.
