As the improvement of technique scheme, described wear ring is set to two groups or one group.
As the further improvement of technique scheme, between two groups of adjacent wear rings, be provided with isolating ring.
Further, often organize in wear ring, between two adjacent wear-resistant elements, be configured to seam; In described some groups of wear rings, the seam of two adjacent groups wear ring mutually staggers in the radial direction of wear ring.
Further, the one-sided or bilateral of the cross section of described wear-resistant elements is dovetail shaped.
Further, adhesive is coated with between described wear-resistant elements and annular dovetail slot.
Further, described wear-resistant elements is made up of Hardmetal materials or stupalith.
Further, described ring-type steel base is made up of GCr15 alloy steel material.
Beneficial effect is: cutting ring of the present invention compared with prior art, wear ring in its operative end surface is formed by some groups, and arranges with one heart, often organizes wear ring and is spliced by fanning annular wear-resistant elements, fan annular wear-resistant elements processing technology simple and be easy to splicing, cost of production is low.Because Scantlings is little, the internal stress accumulated when wear-resistant elements effectively can discharge sintering, possesses higher shock resistance during work.In addition, because be provided with isolation zone, or the seam of each group wear ring is not positioned at same straight line diametrically, can guarantee that the crackle that seam is formed can not be expanded like this and extends and then isolate whole wear ring, thus ensure that cutting ring has good sealing, improve working life.
