Abstract
The utility model discloses a ceramic and metal composite grinding roller for a medium speed mill. The grinding roller comprises a roller core (5) and an arc-shaped liner plate (1) formed by casting high-chromium iron, wherein a groove (2) is formed in the arc-shaped upper surface of the arc-shaped liner plate (1), a ceramic perform (3) is placed in the groove (2), then high-chromium iron is cast in the groove to obtain the wear-resisting arc-shaped liner plate (1), the ceramic perform (3) comprises an upper wire mesh (3a) and a lower wire mesh (3b) which are the same in size, steel wire grooves (3c) are uniformly punched in the lower wire mesh (3b), precast blocks (3d) are filled in the steel wire grooves (3c), the upper wire mesh (3a) covers the upper surface of the lower wire mesh (3b), and the lower surface of the wear-resisting arc-shaped liner plate (1) is connected with the roller core (5) through a bonding layer (4) formed by an adhesive. The ceramic and metal composite grinding roller is simple in structure, low in manufacturing cost, good in wear resistance, and long in service life.
Description
Technical field
The utility model relates to a kind of grinding roller, particularly a kind of ceramet composite grinding roll of medium-speed pulverizer.
Background technology
At present, the grinding roller of domestic medium-speed pulverizer adopts the rich chromium cast iron cast to form, or directly at surface of the work built-up welding rich chromium cast iron, to reach the elongated component purpose of friction durability, still, because the production status environment is very severe, during grinding roller work, higher extruding force, shearing force are born in surface, the current grinding roller of being made by antiwear high-chromium cast iron, and service life is still very short, need the frequent grinding roller of changing, cost is high, and makes troubles to production, greatly reduces production efficiency.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of medium-speed pulverizer ceramet composite grinding roll, and this composite grinding roll wearability improves greatly, long service life.
To achieve these goals, the technical solution of the utility model is as follows: a kind of medium-speed pulverizer ceramet composite grinding roll, it is characterized in that: comprise the arc liner plate (1) that roller core (5) and rich chromium cast iron cast form, the curved upper surface of described arc liner plate (1) has the groove (2) of arc, placing ceramic precast body (3) in this groove (2), described ceramic performs (3) comprises upper steel wire (3a) and the lower steel wire (3b) that size is identical, evenly stamp out steel wire groove (3c) on lower steel wire (3b), ceramics preparative piece (3d) is housed in described steel wire groove (3c), described ceramics preparative piece is bonded together and makes by the rich chromium cast iron molten metal by ceramic particle, described upper steel wire (3a) covers the upper surface of lower steel wire (3b), the lower surface of described wear-resisting arc liner plate (1) is connected with roller core (5) by bonding agent (4), and described ceramic performs (3) becomes one with arc liner plate (1) in groove (2) by the rich chromium cast iron pouring metal melt.
Adopt technique scheme, be placed in the groove of arc liner plate after this prefabricated section is fixed by steel wire, the rich chromium cast iron of then casting is fixed, and forms composite abrasion-proof inner plate, and this liner plate is fixed on roller core, has improved the wearability of grinding roller.Steel wire can play fixedly prefabricated section, allows prefabricated section be uniformly distributed, the effect be not subjected to displacement when cast alloys, and secondly, steel wire is more yielding, can become easily the arc corresponding with the groove of arc, convenient fixedly prefabricated section.
In order to improve wearability: described steel wire groove (3c) is regular queue distribution on lower steel wire (3b), upper distribution 300-800 the steel wire groove (3c) of the lower steel wire (3b) of every square metre, the degree of depth of this steel wire groove (3c) is 10-30mm, and width is 20-80mm.
Beneficial effect: the utility model is simple in structure, low cost of manufacture, and wearability is good, long service life.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The structural representation that Fig. 2 is ceramic performs of the present utility model;
