WE can provide characteristic service and differentiated products according to the different conditions of rolling mill.
Produced by static duplex casting and differential harden heat treatment methods, which ensures the shell/core material matching the rolling condition.
After further heat treatment, the back-up rolls are of the following advantages:
Produced by vertical centrifugal casting method in most cases. Rolls of different type and material are of the following advantages:
Conventional Mill Rolls
customization experts, to provide you with the best solution
LMM is a company specialized in mill roll production and supply. With many years of experience and advanced production equipment, we can provide you with high-quality and reliable mill roll products.
Our rolling mill rolls are suitable for various metallurgical industry fields, including the production of bars, wire rods, section steel, strips, etc. We can customize rolls according to customers’ specific requirements and application scenarios to ensure their performance and life in various environments.
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 3-5times than normal cast iron rolls.
How to find a trustworthy Adamite rolls manufacturer
If you want to find a trustworthy adamite rolls supplier with long-term cooperation, maybe you need to concern about as the following
The equipment plays an important role in the high-quality mill rolls. Types of equipment matters from the beginning to the finished products. LMM has advanced production equipment and the rolls are made of high-quality materials to ensure the production of high-precision, high-quality finished products. The extended life of the rolls means less regrinding costs, fewer roll changes and less downtime.
Different stages of production have to follow controlling parameters to ensure that the production department is working with the required efficiency. To get the quality mill roll, quality is absolutely necessary
A reliable manufacturer will focus on technological advancement for its long-lasting development. The advanced technology can guarantee the improvement of products. The best supplier not only can provide high-standard products but also is the steel solution provider. Before choosing the company you should ensure the manufacture has a professional team for advanced technology.
Delivery time often is the main factor to choose the supplier. Delivery on-time is also the basis of next time cooperation. Checking out the place of the company and the delivery term is essential. Price is also an important element for a best-value mill roll manufacturer.
Cast rolls technical Process:
Modeling → smelting → centrifugal casting → cleaning → preliminary heat treatment → rough machining → differential heat treatment → finishing → packaging and delivery.
Temperature controlled cooling + annealing treatment after casting:
the microstructure transformation is more sufficient and the stress state is more stable.
The composition of the working layer adopts multi-element micro alloying technology:
which takes into account wear resistance and accident resistance, and has better comprehensive performance.
The multi-layer composite technology: is adopted to effectively block the diffusion of high alloy content in the working layer to the core structure and ensure the strength and toughness of the core structure.
Differential heat treatment technology: is adopted to make the microstructure change fully and the stress distribution more stable and reasonable.
Forged steel roll technical Process:
Electric arc furnace smelting → LF \ VD refining → ingot casting → annealing → cleaning → electroslag remelting → annealing → forging → post forging heat treatment → rough machining → preliminary heat treatment → semi finishing → dual frequency quenching or differential temperature treatment → cryogenic treatment → tempering → finishing → packaging and delivery.
Double refining + electroslag remelting to ensure good metallurgical quality
Perfect heat treatment and cold treatment technology to ensure the depth and hardness uniformity of hardened layer
Perfect production process
Cast rolls technical Process:
Modeling → smelting → centrifugal casting → cleaning → preliminary heat treatment → rough machining → differential heat treatment → finishing → packaging and delivery.

Our Client Say?
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.
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.
