The present invention relates to lining units used to protect surfaces exposed to intensive wear by solids, gases and liquids. The lining unit is a metallic shell formed with a pipe of rectangular cross section, containing a metallic plate and a wear-resistant composite material, the shell, the metallic plate and the composite material being diffusion-joined one to another.

DETAILED DESCRIPTION The above and other objects are attained by a lining unit comprising a metallic shell formed with a rectangular cross section pipe filled with a wear-resistant composite material diffusion-joined to the metallic shell.
According to the invention, the metallic shell carries an additional metallic plate diffusion-joined to the metallic shell and to the composite material.
The present invention has reduced roughly by one half the cost of the lining unit as compared to that of known ones through a lesser consumption of costly compounds entering the composite materials.
Another advantage of the present invention is that, depending on concrete conditions, it is possible to substantially lower the weight (mass) of the lining unit.
According to the present invention, it is advisable when the lining units are used for protecting parts exposed to irregularly varying loads, for example, for protecting a crosspiece of a large bell of a 5000-m.
sup.
3 blast furnace, to provide a metallic plate of a variable cross section throughout the length thereof.
In an alternative embodiment of the present invention, the metallic plate is wedge-shaped.
When lining elements are employed to protect large surface areas, it is advantageous, according to the present invention, to have the above metallic plate of a constant cross section throughout the length thereof.
