0.406-1.055Company Profile:
Sanxin Heavy Industry Machinery Co., Ltd. regards product quality as life, ranks first in the machinery manufacturing industry with leading equipment and production capacity and wins widespread praise from customers.The large steel castings and special steel ingots produced by the Company, as well as all kinds of metallurgical rolls used by modern hot strip mills, medium and wide thick plate mills, and various section steels, bars, high-speed wires, medium and narrow strip mills, have won the praise of "golden quality" in the industry by virtue of its delicate work and precise casting.
Product Features:
1. The production process of centrifugal infinite cold hardening rolls adopts centrifugal casting technology, and the molten metal is injected into the mold through a high-speed rotary casting machine, so that the metal is evenly distributed under the action of centrifugal force, and quickly cooled and solidified. The resulting rolls have a dense microstructure, uniform hardness distribution, and no internal defects and porosity, resulting in excellent wear resistance and mechanical properties.
2. The surface of centrifugal infinite chilling rolls is usually shot blasted and case hardened to enhance their wear resistance and anti-sticking. Commonly used surface hardening treatments include electroosmotic hardening, electroplating hard chrome and laser treatment, which can form a protective layer of high hardness on the surface and effectively extend the service life of the rolls.
3. Centrifugal infinite chilling hard rolls are subjected to tremendous pressure and friction during the rolling process of metal materials, so their material selection and manufacturing process are very important. Common materials include high-speed steel, alloy tool steel and special alloy steel to meet the requirements of high strength, high hardness and wear resistance.
