A STEEL

“On September 10, 2015, in the rolling process of the steel rolling mill, the LMMGROUP high-speed steel bar rolling experiment was carried out on the first bar line C12 to four cuts, and C14 three cuts to K1, K2, K3, and K4. According to the trial situation, The average amount of steel passing through LMMGROUP rolling is about 50%-60% of the alloy rolling spoke. The processing difficulty of high-speed steel is low, and the processing cost is lower than that of the alloy rolling wheel. Our factory can achieve normal processing.”

B STEEL

“The trial data shows that the ∮370mm high-speed steel roll produced by LMMGROUP has far exceeded the single-groove assessment value of 1,500 tons in the “Roll Ordering Technical Agreement”, and the effect is good.”

C steel

LMMGROUP provides our factory with 8 @380×650 high-speed steel rolls for K1 (finishing), K2 (pre-finishing), K3 (slicing), K4 (pre-slicing), which are used to make 12mm rebar. After the first online use: K1 single-channel steel throughput averaged 410 tons, K2 single-channel steel throughput averaged 840 tons, K3 single-channel steel throughput was 2860 tons, and K4 single-channel steel throughput was 2910 tons. There is no abnormal condition in the groove, and the hardness of the wheel is uniform, which is convenient for the repair and processing of the groove. During the period, LMMGROUP sent relevant technical personnel to follow up and guide on-site, and the effect was better in our factory.
