With 20 years of expertise in rolling mill rolls manufacturing, we specialize in R&D and production of various metallurgical rolls tailored for steel plants, bar mills, high-speed wire mills, and hot/cold plate and strip rolling mills.
We offer customized solutions and differentiated products based on specific rolling mill conditions, providing exclusive technical support to enhance rolling efficiency and product quality.
We can provide special services and differentiated roll products according to the different conditions of the rolling mill rolls.
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:
HANI 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.
The world No. 1 in crude steel production steel plant, over 85% of the HSS ROLLS for bar and wire are from us.
HANI 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 mill rolls manufacturer
If you want to find a trustworthy adamite mill rolls supplier with long-term cooperation, maybe you need to concern about as the following
The quality of mill rolls starts with cutting-edge production equipment. HANI Tech utilizes state-of-the-art machinery and premium materials to ensure high precision and durability. Longer roll lifespan reduces regrinding costs, replacement frequency, and downtime, boosting overall productivity.
Quality is non-negotiable. A reputable manufacturer enforces rigorous quality checks across all production phases to meet industry standards. From material selection to final inspection, every step ensures consistent performance and customer satisfaction.
Leading manufacturers prioritize R&D and technological upgrades to stay competitive. Advanced technology enhances product quality, efficiency, and customization options. Choose a supplier that acts as a steel solution partner, offering innovative solutions beyond standard products.
Timely delivery is critical for maintaining production schedules. Evaluate the supplier’s location, logistics capabilities, and delivery terms to ensure reliability. Combine this with cost-effective pricing to secure high-value mill rolls without compromising quality.
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.
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
Cast rolls technical Process:
Modeling → smelting → centrifugal casting → cleaning → preliminary heat treatment → rough machining → differential heat treatment → finishing → packaging and delivery.
Technical excellence in our core competencies – melting, casting, forging, heat treating and machining – allows us to provide a superior product and meet the most demanding requirements of our customers.
The trial data demonstrates that the ∮370mm high-speed steel rolls produced by HANI have significantly surpassed the single-groove assessment threshold of 1,500 tons stipulated in the “Roll Ordering Technical Agreement”, achieving excellent performance.
On September 10, 2015, during the rolling process at a steel mill, HANI’s high-speed steel bar rolling experiment was conducted on Bar Line C12 (four cuts) and Bar Line C14 (three cuts to K1, K2, K3, and K4). Based on the trial results, the average steel throughput of HANI’s rolls reached approximately 50%–60% of that of alloy-based rolling rolls.
Key advantages include:
