Title: Lise Castonguay: Innovator in Cement Technology for Electrolytic Cells

Introduction

Lise Castonguay is a prominent inventor based in Chicoutimi-Nord, Canada. She has made significant contributions to the field of cement technology, particularly in applications for electrolytic cells used in aluminum production. With a total of 3 patents, her work has been instrumental in enhancing the efficiency and reliability of these systems.

Latest Patents

One of her latest patents involves a specialized cement for collector bar-carbon block joints of electrolytic cells. This innovative cement is designed to ensure a strong bond between the cathode collector bar and carbon block, which is crucial for the production of aluminum. The formulation includes an aggregate of anthracite, graphite, or mixtures of both, combined with a curable water-soluble liquid polymeric resin and water. The high fluidity of the cement allows it to be poured into slots in the carbon block, where the weight of the bar forces the cement to form a secure joint. This cement exhibits a linear shrinkage of 4-5% when subjected to high temperatures, preventing cracking and ensuring a reliable connection.

Another patent focuses on a similar cement formulation that utilizes calcined anthracite or an anthracite/graphite mixture. This version is designed to maintain a linear shrinkage of about 0.3 to 1.5% under operating temperatures, ensuring that the electrical connection between the collector bar and carbon block remains intact without causing damage.
