Rolling Mill Manufacturers
We provide Rolling mills capable of producing Bar rods from sizes 8 to 40 mm with the production capacity ranging from 75000 to 500000 TPA.
The Bar rods are made with Billets/Ingot which passes through various stands to get the desired shape and size. The bar then passes through the quenching system and gets self-tempered and quenched. The process is undertaken to increase the strength of the rebars.
The Rolling mill comprises the following process flow:
- Re-heating Furnace
- Rolling Mill Train
A) Rolling Mill Train – Equipment- All mechanical equipment incorporates the latest known and proven technology.
Finishing Line mill stands are Housing less series, which are very well known worldwide for their rigidity and easy maintenance. The “housing less” stands can be used for producing all grades of steel including stainless high speed and high alloy steel. Special “robots”, in the stand preparation shop, are used for quick roll changing thus reducing the requirement for costly spares and stand-by equipment.
All the rolling mill stands are individually driven by DC motors and the rolling process will be in tension control in the roughing and intermediate mills, while in the finishing stands will be no-tension control using loopers.
Crank and flying shears are provided to remove the oversize head of the bar as it progresses down the rolling line. This feature ensures easy entry into the rolling mill stands and minimizes cobbles. As you can note the offered stands are divided into four main size groups. The main advantages of this solution are:
B) Rolling Mill Train – Roll Pass Design – The roll pass design has to reduce to the minimum the investment in rolls and consequently the operation cost and, moreover, to allow high productivity and high final quality of the products. The main characteristics of the proposed roll pass design are:
2. Quenching System: After leaving the finishing stands, to improve the mechanical properties of the deformed bars, an in-line water quenching system is foreseen. The main benefits that we can have with this system are High yield strength of the material, Better weldability of material, Lower cost of material, High plasticity of bars after treatment, and Better stiffness of the bar.
3. Cooling Bed: Just after rolled, the bars are subdivided by a flying shear in multiple commercial lengths and sent to the cooling bed onto a roller table provided with aprons. The electrically driven mobile elements break the rolled stock materials and discharge them onto the racks of the cooling bed. A series of fixed and moving rakes are foreseen to collect and cool the bar coming from the roller table with aprons. The moving racks are operating automatically by the gear reducer start-stop drive. During their transport materials are cooled and discharged then onto chain transfer that shifts materials layer in the required number until take-out system provides to pick-up each layer of bars and laid them to the cooling bed run-out-roller table to feed the final commercial cold cut line.
4.Run-Out Roller Table: The system is provided to keep in position the layer, made on the pitch-to-pitch chain transfer at the cooling bed exit, during its transferring onto the run-out roller table.
5.Cold Cutting to Length Area: The final cold cutting operation will be performed by means of the Cold Static Shear. This machine, for such type of profile, is the most suitable for cut quality and in cutting costs. The shearing is performed by a pair of blades, one of which is fixed and the other mounted on a movable slide, which every time is started and stopped by an air-operated clutch/brake group by an AC motor.
6.Bundling Area: The bundling area consists of chain transfers for layer transportation and layer buffering(during bundling floatation) and finally chain transfer depositing the counted bars in the bundle forming area. The chain transfers system duty is to transfer the bar layers to the bundling area, and, when the bundle is informing position, to act as a buffer system.
7.Collecting Area: When the bundle is ready, by means of the adjustable roller table, it will be transferred to the tying area where the wire tying machine, hydraulically operated, will tie the bundle in the required numbers of ties. When the tying operation is finished, the bundle is transferred to the collecting area where it will be also weighed and labeled accordingly.
The specialty of our Rebars high flexibility and proven reliability. Our state-of-the-art Rolling Mills can manufacture an array of products like angles, squares, flats, channels, rounds, and wire rods. This top versatility also means you can efficiently produce all sizes, materials, and alloys.
We as a system supplier, offer you Mechanical Equipment clubbed with electrical and automation systems, plus technological expertise from a single source. That ensures the products you make in plants set up by us always make the grade in terms of both quality and efficiency.
