На основе математической модели, описывающей влияние углерода (С) и углеродного эквивалента (Сэкв) на предел прочности на растяжение (σв) конструкционного чугуна, выполнено параметрическое описание поверхности отклика σв=σв(С, СЭКВ). Показано, что для рассмотренной модели в виде уравнения регрессии применение ридж-анализа позволяет найти множество субоптимальных значений входных переменных (С, СЭКВ), обеспечивающих получение заданных марок конструкционного чугуна. Графическое представление таких множеств формирует номограмму для расчета субоптимального химического состава конструкционного чугуна
