high quality ladle continuous stuffing sand

Stuffing sand, also called drainage sand or filling sand, is a filling refractory material used at the bottom of the ladle. It is an important refractory for the steel casting. Ingredient of 20-40 mesh foundry stuffing sand is Aluminum trioxide with small amount of silica.

Features:

1. Can sinter at low temperatures, in order to avoid sand float during pouring into molten steel;

2. Do not sintered too thick after a long time smelting at a high temperature in order to achieve automatic opening and pouring, improving productivity, reduce steel water pollution, reduce flue gas consumption, ensure the safety production.
