Tuqiang Company has gradually developed into a scientific and technological refractory company integrating R&D, design, production, processing and service since it was founded more than 30 years ago. It is especially devoted to the overall contracting project of continuous casting tundish. Over the years, Tuqiang Company has carried out in-depth and systematic research and development and continuous improvement on the complete set of refractories for tundish, and produced a series of refractories for tundish that can not only ensure the safe production of continuous casting, but also increase the benefits for customers. Guided by the development of continuous casting industry, combined with the specific working conditions of on-site production, the company has greatly strengthened its investment in research and development, produced and constructed in a more scientific way, and introduced domestic advanced fully automatic production lines for the purpose of meeting customer needs, making the production process more environmentally friendly, safe, efficient and accurate, and making the product quality more stable. Meanwhile, we pay attention to after-sales service, go deep into the customer site to understand the use of products, solicit customers' opinions, and constantly improve our overall service level.
