Our hot rolling line utilizes the Accu-Roll mill system which is a cross rolling system. The Accu-Roll mill system increases the rolling angle and the length of rolls, uses upper and lower guide discs to improve the wall thickness precision, rolling speed and production capacity. It is suitable for the production of medium- and thin-walled tubes in small batches and multiple specifications, and it is widely used for the production of OCTG and precision tubes. So far TYHI has designed and manufactured Φ273mm and Φ219mm Accu-roll hot rolling lines.

Our key products include our 1200t EOT crane, our 500t ladle crane, our 75m³ shovel for mining, our Φ180mm continuous rolling production line, our 110 MN aluminum alloy extrusion press and our 7m top charging coke oven equipment. 

TYHI’s products are widely used in the metallurgical, mining, energy, transportation, aerospace, chemical, rail, ship building, environmental protection and various other industries. Many products designed and manufactured by TYHI have filled gaps in the domestic market. Furthermore, we have created 360 nationally and internationally recognized products which have been exported to approximately forty countries and regions.

TYHI is now delving further into the development of the rail, engineering machinery, new energy, and maritime equipment fields. We have established a new production base in the Binhai New Area of Tianjin to facilitate the transportation and export of large-sized equipment. Our second wheel production line is currently under construction. We have also established production lines for wheels, axles and wheel sets for use at speeds above 200 km/h.

We are now turning our focus to international markets which we are certain can benefit from our high quality products and service. As we are constantly innovating and improving, we have no doubt that we will meet and even exceed our customers’ expectations.
