The invention discloses a multi-element low-alloying treatment technical method for high-strength gray
cast iron, and belongs to the technical field of
casting. The method comprises the following steps of A, determining the components and proportion of furnace charge in a high-strength
gray iron casting, a matching method and content range of various
alloy elements and a content range of conventional chemical elements according to the requirements of a to-be-produced
casting; B, determining a melting process procedure of the high-strength
gray iron casting; C, preparing materials, charging, heating and melting according to the requirements of "
cast iron melting burdening process sheet"; D, sampling and analyzing the chemical components of an iron liquid in a furnace, and adjusting the chemical components of the iron liquid in the furnace; E, carrying out molten iron treatment and tapping pouring; and F, detecting the material performance of the high-strength
gray iron casting. The method provides a simple and feasible chemical component determination, melting burdening and
alloy liquid treatment method, so that
alloy element matching,
cast iron melting burdening and alloying treatment of the high-strength gray cast iron are more accurate and convenient, and cast iron melting operation control is more reasonable and feasible.
