Adamite rolls

The adamite rolls also called adamite Steel Rolls has better strength and toughness than cast iron roll. It is widely used for work rolls in hot rolling mills. The adamite rolls are statically cast and go through a multi-stage heat treatment process followed by Tempering phases in order to develop the combination of hardness, toughness and wear resistance.

Adamite rolls chemical composition

The adamite roll materials can be considered as composite materials of two phases of coarse carbides and matrix. As a consequence, the hardness of these roll materials may be markedly affected by the amount and hardness of coarse carbides. The carbon content of the alloy adamite roll is usually between 1.2-2.3% and the rest alloy elements contain Cr, Ni, Mo V, etc. The free carbide mass fraction is generally about 6% to 10% with small hardness drop, good wear resistance, good toughness, significantly reduced consumption. The Standard includes ISO, GB, ASTM, DIN, JIS.

The table of adamite rolls chemical composition as follows

How to find a trustworthy Adamite rolls manufacturer

If you want to find a trustworthy adamite rolls supplier with long-term cooperation, maybe you need to concern about as the following

1.Mill rolls equipment

The equipment plays an important role in the high-quality mill rolls. Types of equipment matters from the beginning to the finished products. Compared with alloy cast steel roll, adamite roll has a good abrasion resistance through a special heat treatment process, so for the products, the equipment ever much more important.

2.Quality Control

Different stages of production have to follow controlling parameters to ensure that the production department is working with the required efficiency. To get the quality mill roll, quality is absolutely necessary

3. Technological Advancement of the manufacturer

A reliable manufacturer will focus on technological advancement for its long-lasting development. The advanced technology can guarantee the improvement of products. The best supplier not only can provide high-standard products but also is the steel solution provider. Before choosing the company you should ensure the manufacture has a professional team for advanced technology.

4. Delivery time and price of the companyDelivery time often is the main factor to choose the supplier. Delivery on-time is also the basis of next time cooperation. Checking out the place of the company and the delivery term is essential. Price is also an important element for a best-value mill roll manufacturer.
