Also presented recommendation on the rational choice of geometrical parameters of borings crowns for the machines of dissection of cast-iron letok of high furnaces. The results of experimental researches, directed on the exposure of dependences of dynamic coefficient of friction of sliding of hardening letochnoy mass at material of boring crown of machine of dissection of cast-iron letki of high furnace from such factors as relative speed and effort of co-operation are in-process resulted. It is rotined that dependence of coefficient of friction on speed is nonlinear Product Description popup.authors Мушенков Ю.А. Селегей А.М. popup.nrat_date 2020-04-02 Close
