Grindwell Norton Limited of India has entered into a definitive agreement with Shinagawa Refractories Co. Ltd. of Japan on 11 July 2019, to form a new refractory company which will manufacture mainly Tap Hole Clay (Tap Hole Mass) refractory products for the steel industry.


Modern blast furnaces have a tap hole length ranging from 2 to 3.5 meter. The tap hole mass has the task of closing the tap hole and to protect the walls on the inside as they are particularly stressed by the intense tapping flow. Blast furnace tap hole clay mass is a ready-to-use refractory product, whose main constituents are - bond of aggregates, additives, and plasticizers or clays. It is used to close the tap hole of a blast furnace after tapping so that no material can leak out of the furnace, and to keep it plugged until the tap hole is opened for next tapping. It is applied to ensure periodical and stable tapping from the blast furnace and also to protect the inner surface of tap hole bricks.
