Steel plant process
1. The choice of raw materials: the production of ductile iron rolls needs to use ductile iron materials, so the choice of high-quality ductile iron materials is a very important step, we will be based on your needs, put forward suitable for your recommendations.
2. Smelting Production: In the ductile iron casting furnace, the raw materials of the casting process, namely molten iron and metallurgical coke (or scrap steel, waste castings) of the corresponding components are poured into the furnace, and the proportion of components varies according to the different furnace types; The properties of molten iron and slag are broken and dispersed by high speed hot air and grinding wheel nozzle. After a certain period of heat preservation, it is necessary to add a nodulator to make the hot metal into ductile iron.
3. Casting production: In the industrial production of rolls, the molten ductile iron material is poured into the sand mold for casting. The specific casting process includes sand mold making, mold frame making, pouring, cooling, sand cleaning, grinding and other steps.
4. Finished product processing: After the completion of ductile iron roll casting, finished product processing, including outer diameter turning, inner hole processing, surface turning, etc., all processing processes follow industry norms and standards to ensure the quality, safety and stability of each billiard graphite iron rolling mill.
Production advantage
Pearlite ductile iron roll I is suitable for roughing mills and can meet the rough rolling needs of metal billets of different sizes and materials, including steel billets, aluminum billets, etc. Compared with some more expensive roll materials, pearlitic ductile iron rolls have lower manufacturing costs, but their performance can still meet the requirements of roughing mills and are cost-effective. SGPII rolls have high strength and toughness, can withstand high pressure and impact loads, and are not prone to breakage or deformation, ensuring the stability of rolling. SGPIII rolls can maintain good hardness and shape stability at high temperatures, ensuring the dimensional accuracy of rolled products. SGPIII rolls can improve the production efficiency of the finishing mill, reduce downtime during the production process and the frequency of roll replacement, thereby reducing production costs.
