What kinds of commonly used cast iron rolls are there?<\/strong><\/h3>\n\n\n\n

Cast iron rolls are further divided into four categories: <\/strong>chilled cast iron rolls, infinite chilled cast iron rolls, ductile iron rolls and high chromium cast iron rolls.
Due to the difference in composition, inoculation, cooling rate, heat treatment, etc., cast iron has formed a huge system. Various cast iron rolls have different structures and properties and can be used in different rolling mills.<\/p>\n\n\n\n

Alloy chilled cast iron roll<\/h3>\n\n\n\n

Alloy chilled cast iron roll (roll ring) is a cast iron roll manufactured by using the subcooling degree of molten iron itself and the cooling of the mold surface, and adding Ni, Cr, Mo alloy elements at the same time. The basic structure of the working layer of the roll body is basically There is no free graphite, so it has high hardness and excellent wear resistance.
This kind of material can be used to produce large-scale rolls by static composite casting process,<\/strong> so that the roll body has high hardness and the roll neck has high strength and toughness, showing good thermal stability and accident resistance.<\/p>\n\n\n\n

Alloy Unbounded Chilled Cast Iron Rolls<\/h3>\n\n\n\n

Alloy unbounded chilled cast iron rolls. Graphite is uniformly dispersed throughout the cross section of the roll body, and its number and size increase with depth. The alloy unbounded chilled cast iron rolls provided by our company are due to the addition of manganese, chromium, nickel, molybdenum and other alloying elements, plus the presence of a small amount of fine graphite. It not only the peeling resistance, thermal crack resistance and wear resistance of the roll are improved, but also the working layer of the roll body has a smaller hardness drop and the fine graphite pores on the surface also improve the bite ability of the roll.<\/p>\n\n\n\n

High nickel-chromium unbounded chilled cast iron rolled spokes<\/h3>\n\n\n\n

High-nickel-chromium unbounded chilled composite cast iron rolls are high-performance rolls manufactured by centrifugal or full flushing methods. By increasing the content of nickel, chromium, molybdenum and other alloying elements, high microhardness of microstructure and carbide can be obtained; with special heat treatment, a working layer with uniform structure, compactness and small hardness drop can be obtained; at the same time, it contains a small amount of free graphite, so it has good microhardness. Abrasion resistance, thermal cracking resistance, spalling resistance and indentation resistance.<\/p>\n\n\n\n
