At nine o’clock in the morning on December 19, 2023, the LMMGROUP product manager accompanied the German agent to the Hangzhou roll production base. After the welcome ceremony, he visited the production workshop. Production process: casting [10 intermediate frequency furnaces of 1 ton, 3 ton, 5 ton, 10 tons, etc.] – heat treatment [15 heat treatment furnaces] – rough machining – finishing – inspection – packaging. The designed production capacity is 18,000 tons. This year’s production capacity is 13,000 tons, with rolls accounting for 90%, of which HSS rolls account for 20% and roll rings account for 10%. There are 6 centrifuges, horizontal centrifugal production.

After visiting the factory and office, we went to the conference room to discuss technical issues related to tolerances and hardness. The LMM GROUP factory has purchased two new high-precision CNC lathes, which will arrive at the factory at the end of the month. We are determined to improve the accuracy of order production in the future and ensure tolerances. The agent was very pleasantly surprised and said that the production base is very large and the management is very good. He also believed that the factory would have the ability to handle future orders.

Generally it is 5-10 days if the goods are in stock. or it is 15-20 days if the goods are not in stock, it is according to quantity.

Product advantage

The world No. 1 in crude steel production steel plant, over 70% of the HSS for bar and wire are from us.

LMM high-speed steel rolls have higher steel passing per groove (times) due to their good wear resistance, which saves roll changing time, improves rolling mill operation rate, reduces roll consumption, and improve the overall efficiency of the factory.
Generally, the amount of steel passing in a single groove (times) is 3 to 5 times that of cast iron rolls.
