ーの耐久性を向上させている。[Prior Art] Conventionally, abrasion-resistant liners have been used inside casings and the like in ore, coal, etc. crushers. High chromium cast iron and other materials have excellent wear resistance as materials for wear-resistant liners, but on the other hand, they have extremely poor workability and weldability, and mechanical connection methods such as bolts are the only way to attach them to the mounting plate. It was getting worse. Furthermore, the surface where the wear-resistant liner is used may be damaged due to collision or sliding with ore, coal, etc.
When the wear gradually progresses and reaches the level of the bolt head of a square bolt, the square bolt will no longer be able to be securely attached to the wear-resistant liner and the mounting plate, and will no longer be usable. Using a friction welding method different from mechanical coupling means, the use of square bolts is omitted and the durability of the wear-resistant liner is improved.

This is a recess provided on the back surface of 0, that is, on the mounting surface 34 side, and is formed in a dish shape. A fitting 38 is frictionally welded to the recess 36 of the wear-resistant liner 30, and 46 indicates a burr at the joint of the fitting 38 caused by the friction welding. The plane portion of the recess 36 is pressed against a burr 46 having a size determined by the bonding conditions with a sufficient margin. Thus, the fitting 38 of the wear liner 30
is securely inserted into the hole 42 of the mounting plate 40. 32
3 shows the use surface of the wear-resistant liner 30, which is used as ore, coal, etc. collide with or slide on the use surface 32, and wear gradually progresses.

In this case, since it is manufactured by casting, a mold is required, and in particular, when forming the recess 36 on the mounting surface 34 side, not only does it require a lot of labor for the molding, but also friction welding is performed in the recess 36. If the fitting conditions are not appropriate, the burr may have different dimensions, resulting in a decrease in joint strength.
There was a problem that it could not maintain sufficient strength and was easily damaged when subjected to external loads.

indicates the back side of the liner 10, and 16 indicates the back side 14.
It is a recess provided in the back surface 16, and is formed in a continuous groove shape along the back surface 16. The liner having the cross-sectional shape shown in FIG. 2 is continuously cast into the shape of a mold using a continuous casting method, and then processed to the required length to produce a flat liner. Reference numeral 18 denotes a fixture, which is made of carbon steel. Recess 1 on back surface 14 of liner 10
A fitting 18 is friction welded to a part of 6,
Reference numeral 19 indicates a burr at the joint of the fixture 18 caused by friction welding. The outer diameter and thickness of the burr 19 are controlled by the bonding conditions between the liner 10 and the fixture 18, and the recess 16 is filled with the burr 19 having dimensions determined by the bonding conditions.

れている。 Thus, as shown in Figure 3, liner 1
The fitting 18 of No. 0 is securely inserted into the hole 22 of the mounting plate 20. If the above bonding conditions are not appropriate, cracks in the liner 10 and excessive or insufficient burrs 19 will occur, and the strength of the joint will decrease, so the bonding is performed under appropriate bonding conditions. In particular, by reliably filling the recess 16 with the burr 19, high joint strength can be obtained, and when the fixture 18 is subjected to an external load, it can maintain sufficient strength and prevent breakage. It is possible to eliminate problems that may cause damage such as. Next, even if wear progresses on the use surface 12 of the liner 10, the fitting 18 remains connected to the liner 10 without coming off.
