Recommended applications of grades for carbide roll rings

Product Details

At present, the finishing mill is generally composed of 8-10 stands. Because of the big size of the fracture surface of the rolled part, the collar on the front stands of the finishing mill may resist heavy duty and strong impact. Thus, the high hardness and good thermal fatigue resistance are the primary factors, which are prior to wear-resistance. While there is low load and impact for the rear stands, we shall pay more attention to the wear-resistance and thermal fatigue resistance of roll rings.

This manual describes the grades and properties of our cemented carbide roll rings in detail so that you can make the correct choice.

Grade Recommended applications
LMM08R Maximum hardness, excellent wear resistance in the series. Used in the last 1~2 stands of good high-speed rolling mills for rolling common and hard steel bars.
LMM10R Higher wear resistance. Mode rate impact resistance in the series. Used in the last 1~2 stands of good high-speed finishing rolling mills for rolling common and hard steel bars.
LMM12R High wear resistance and corrosion resistance. Used in the last 1~4 stands of finishing mills.
LMM15R Moderate wear resistance and impact resistance, good for general purpose. Used in the last 1~4 stands or all stands of finishing mills.
LMM18R Good toughness and thermal crack resistance, good for general purpose. Used in most stands of the finishing mills and the rear stands of common mills.
LMM20R Best for general purposes. Used in the front stands of good rolling mills and in the rear stands of common rolling mills.
LMM25R Used in the first and second stands of finishing rolling mills and in the stands of pre-finishing rolling mills. For every stand of rolling lines for tow speed rolling low precision and unstable operations.
LMM30R Maximum binder content in LMMR series, good toughness and thermal crack resistance. Used in the stands of pre-finishing rolling mills and for rolling rings for hot rolling of ribbed steel.
LMM 32R With good toughness and impact resistance, used for bar, deformed bar finish stand rolling.

 

Grade Recommended applications
LMM06H It possesses the highest hardness and the best wear-resistance among all the varieties of cemented carbide roll rings, thus used for the rolling of common wire and hard wire on the last 1~2 stands of high- speed wire rod finishing mill.
LMM08H It possesses better wear-resistance and moderate impact-resistance with the hardness second to LMM06H among all the varieties, thus used at the last two stands of high-speed wire rod finishing mill.
LMM10H It possesses the moderate wear-resistance and impact resistance, thus used at the last 3~4 stands of high-speed wire rod finishing mills.
LMM15H Moderate wear resistance and impact resistance, good for general purpose. Used in the last 1~4 stands or all stands of finishing mills
LMM20H Best for general purpose. Used in the front stands of good rolling mills and in the rear stands of common rolling mills.
LMM25H Maximum binder content in LMMH series, good toughness and thermal crack resistance. Used in the stands of pre-finishing rolling mills and for roll rings for hot rolling of ribbed steel.
LMM30H Maximum binder content in LMMH series, good toughness and thermal crack resistance. Used for roll rings for hot rolling of ribbed steel and in the stands of pre-finishing rolling mills.
LMM32H With good toughness and impact resistance, used for bar, deformed bar finish standing rolling.
Grade Recommended applications
YGR20 High wear resistance and corrosion resistance. Used in the last 1~2 stands of finishing mills.
YGR25 High wear resistance and corrosion resistance. Used in the last 1~3 stands of finishing mills.
YGR30 Good toughness, wear resistance, corrosion resistance and thermal crack resistance. Used in the middle and rear stands of finishing mills.
YGR40 Good roughness and thermal crack resistance, good for general purpose. Used in the most stands of the finishing mills and in the rear stands of common mills.
YGR45 Good toughness and thermal crack resistance. Used in the front stands of finishing mills.
YGR55 Good impact resistance. Used in the stands of pre-finishing rolling mills for hot rolling ribbed steel bars and they can be machined with turning and milling.
YGR60 Good impact resistance. Used for hot rolling ribbed steel bars and in the first and second stands of pre-finishing rolling mills.
YGH40T With good toughness and shock resistance, used for preferably high speed wire rolling machine, rolling small size deformed bar finish stand.
YGH45T With good toughness and shock resistance, used for general high speed wire or common rolling machine, rolling small size deformed bar finish stand
