Product Description

Alloy Cast Steel Rolls (AS)

As a prolific organization, we are well known for presenting a quality range of Alloy Cast Steel Rolls. Generally, the advanced product range is ideally used for different blooming mill and roughing stands required for light and heavy section mill. These rolls are hypo-eutectoid steel rolls alloyed with Chromium and Molybdenum. A series of heat treatment is done on these rolls that involve normal double annealing method instantly followed by tempering cycle that improvise the toughness. We are offering these Alloy Cast Steel Rolls to our esteemed clients at economical rates.

Key features:

Good thermal shock resistance
High degree of weldability
Good mechanical strength

FAQs of Alloy Cast Steel Rolls:

Q: How are Alloy Cast Steel Rolls manufactured?

A: Alloy Cast Steel Rolls are produced using either centrifugal or static casting methods. This is followed by heat treatment processes such as induction hardening and tempering, ensuring a smooth, machined surface, refined microstructure, and uniform hardness throughout the roll.

Q: What are the main applications of these steel rolls?

A: These rolls are primarily used in rolling mills for both hot and cold rolling processes, section rolling, and bar and rod mill operations. They are suitable for handling steel, copper, and a variety of non-ferrous metals in demanding industrial settings.

Q: When should I choose a customized roll specification?

A: You should opt for a customized specification when your production requirements demand specific dimensions, weight, belt width, or surface finish to match unique operational setups or to comply with particular industry standards or customer project needs.

Q: Where are these Alloy Cast Steel Rolls commonly supplied from?

A: These rolls are widely distributed, exported, and supplied by manufacturers and traders in China, adhering to global standards such as ASTM, DIN, JIS, and GB, making them accessible for both domestic and international markets.

Q: What is the process for ensuring roll hardness and durability?

A: After casting, the rolls undergo induction hardening to achieve a surface hardness of 40 to 85 HSD and core hardness of 30-50 HSD. They are then tempered to improve toughness and extend operational life, delivering high wear resistance and uniform hardness.

Q: How can these rolls benefit my production line?

A: Their high wear resistance, good toughness, and consistent hardness help reduce downtime, enhance product quality, and maximize service life, ultimately lowering maintenance requirements and improving overall productivity.
