About TSR
OUR COMPANY
TSR is an integral company capable of supplying all types of rolling mill rolls as well as technical assistance services to our customers in order to improve the operation of the rolling mills.
TSR has a team of experts composed of Doctors and Engineers with long experience in Metallurgy and Rolling. Our goal is to supply the best rolls at the best price, allowing our customers to improve their quality and TCO.

R&D
Only companies that actively invest in R&D in order to meet the needs of their customers can survive in an increasingly competitive market. TSR is always listening to the needs of our customers, actively pioneering innovation with high quality products to satisfy our customers' demands.
Our company has passed ISO 9001: 2008 quality system certification and ISO 14001: 2004 environment mental system certification. Many of our products have won the national patents, and have been assessed as a high-tech enterprise in JIANGSU province.
HEAT TREATMENT
During the roll manufacturing, many materials require to go through one or more Heat Treatment cycles to reach the most appropriate mechanical conditions and the best microstructure. The resistance furnace used by TSR can realize a multi-point accurate temperature control and ensure the stability of temperature in the furnace. The conditions of heating and cooling environment in different furnaces are all controlled by computers, to make sure that the rolls processed by different furnaces have the same structure and properties.

MACHINING
CNC Lathes, CNC Grinders and a series of automatic processing equipment are operated and inspected by skilled staff who engaged in roll manufacturing for years, which means they can calmly deal with the strict accuracy and tolerance requirements.

QUALITY ASSURANCE
Our Company keeps every step of the roll manufacturing under strict supervision, from heat treatment to machining. We are pleased to say that we realize the continuous quality control of the whole process. The data of all kinds of inspection instruments is collected directly by computer, which provides a modern means and a more efficient way for the quality controlling process.
