1. Ceramic Foundry Sand Introduction
Bauxite Casting Sand (also called ‘Ceramsite’) are innovative spherical casting sand developed in the Far East initially for the discerning Japanese markets. With the excellent casting property feedback and lower price. Ceramsite has already conquered the Japanese and Chinese markets, and being considered as a direct replacement for Chrome and Zircon casting grade Sands. Available in a variety of AFS sizes, The Ceramsite offers a “Chrome Free” option where environmental considerations are a real concern.
Our high quality Ceramisite sands are made by fusing, spraying, sieving and purifying high Alumina Calcined Bauxite. They can be used in casting all sizes of steel parts. The spherical shape produces high density material with excellent flow characteristics. The main chemical composition is Al2O3 which provides an excellent refractoriness and stability.
Ceramsite is ball-shaped, high heat-resistant, low heat dilating rate. it has advantage of cost and performance than Chromite sand and zircon sand that provide the effective ways to improve the quality of the foundry, cost-down and less damage to the environment.
