China's current general wear resistant material series of high manganese steel series: such as high manganese steel (ZGMN13),

High manganese alloy (Zgmn13Cr2MoR), ultra-high manganese alloy (Zgmn18Cr2MoR), etc.

High manganese steel (such as ZGMN13) under severe impact or contact stress, its surface will rapidly harden, while the core still maintains a strong toughness, hard outside and tough inside both wear resistance and impact resistance.And the heavier the impact on the surface, the more full the surface hardening, the better the wear resistance.Because the hardness of high manganese steel itself is very low (HB170-230), the wear resistance is extremely limited before hardening. If the surface of high manganese steel is not enough to bear the impact force, the surface can not be fully hardened (after full hardening, the surface hardness can reach HB550 or below, otherwise), then the wear resistance will not play a role, and the wear resistance will not be shown.

Because Zgmn18Cr2 contains more manganese, the surface hardening can be more sufficient, so more wear-resistant.

Of course, ZGMN18Cr2 series (such as ZGMN18Cr2MORE) is also more expensive than ZGMN13 series.

Autogenous mill / AG mill liner

The company can be specialized in the production of citic heavy industry self - mill lining and luokuang self - mill lining, MZ series self - mill barrel lining. Its strong casting and forging, heat treatment and machining capacity, strict quality and process control methods, perfect testing and experimental means, so that its production and development of various wear-resistant products enjoy a high reputation in China, and sold overseas.

The structure and size of the liner are optimized by using the internationally recognized advanced liner simulation software.

The cylinder and the end cover liner are made of wear-resistant chromium-molybdenum alloy steel, and the convex liner is used to improve the service life and grinding effect.

The liner is fastened with a flat head bolt, matched with a self-locking nut and a sealing washer. Connection bolts have special sealing measures to prevent leakage of pulp.

The number of bolts fixing the lining plate is 5% rich.

Wear-resistant rubber filler strip is used in the joint of end cover liner plate and barrel body. They are fixed by close liner plate.

Rubber liner between cylinder and liner, 6mm thick, reduces noise.
