Furnace rolls are the most important parts of the continuous annealing furnace.The function of furnace rolls is to make the annealing furnace run efficiently. Its working condition is the decisive factor if annealing hearth furnace can be normal production. They are often used in metallurgical industry, steel industry, food industry, etc., and can work at 800-1200 ℃.
The various roll/roller are of good heat, corrosion, wear-resistant properties, working at high-temperature environment on average: 800 to 1200° C, which are used in the steel mills, like continuous annealing line, continuous galvanizing line.
Centrifugal casting for barrel/tube
Forging for journal/shaft
Static/investment casting or sand casting for cone/trunions
welding and machining and grinding.
The high nickel alloy, high chrome heat resistant alloy, cobalt-base alloy, like HU, HT, HK, HP, HW, 24/24NbTiZr, 50Cr/50Ni (2.4813), 1.4865, 1.4849, 1.4848, 1.4410, 1.4059, 1.4841, 1.4845, 1.4852, 2.4879 or as per customer’s requirements.
The roller can be forged in perfect quality and also manufactured by centrifugal cast. The ceramic molds centrifugal castings offer many advantages, as to the flexibility of diameter and length. The production is dense, sound castings, and has almost the same mechanical properties as forging production. The production can be machined to different rollers, hydraulic cylinders, pipe models, etc.
Our products are used in the industry, with international quality standards. Take customer needs and experience as the first principle.
