In manufacturing, "heat" is an indispensable element such as baking, melting, and chemical reactions. And heat-resistant materials are always used in these equipment and furnaces. Various insulation materials such as fireproof bricks, insulating bricks, fibers, and ceramic materials that can withstand high heat. In heat treatment and various furnaces, we will consider and propose energy cost reduction (high-efficiency insulation), longer service life, and reduction of running costs together with our customers. Because it is an old industry, we will make new proposals from a new perspective and take a step forward in new challenges!
