MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202641024725 A) filed by Karthikeya Innovative Industrial Materials And Solutions, Eluru, Andhra Pradesh, on March 2, for 'sacrificial wear block attachment to the pig casting mould for extending service life.'
Inventor(s) include Gamini Purna Sai Sree Ganesh; and Addepalli Veera Sreenu.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "A sacrificial wear block system for extending the service life of Pig Casting Machine (PCM) moulds (103) used in ladle-less/direct ferroalloy casting is disclosed. In such systems, molten ferroalloy from a submerged electric arc furnace (105) flows through a tap hole (104), molten metal channel (106), and direct discharge channel (101) into moulds mounted on an endless conveyor (102), with slag removed via outlet (107). Repeated high-velocity impingement at a confined pouring zone produces localized through-thickness damage (201), leading to premature mould failure. The invention provides a predefined slot (301) at the identified impact zone and a sacrificial metallic block (401) seated therein. The block includes a planar base (402), side mating surfaces (403), and a raised hump structure (404) configured to absorb erosive impact. The block undergoes controlled wear and is replaceable without replacing the parent mould body (103), thereby preventing through-thickness erosion (201), reducing mould consumption, and significantly extending operational service life."
