Grid plate for crusher is the key working part of the hot crushing system of sintered production line, and military service operating mode is severe, and work temperature is at 600-800 DEG C
Scope, its service life are directly connected to the integral device utilization rate or repair rate of sintered production line.Grate plate is in working condition
Under be primarily subjected to the abrasive wear of high temperature mineral aggregate, in the case where tail discharging point is close to grate plate, grate plate is born larger sometimes
Impact, this is a kind of very severe working environment.The grate plate that domestic major iron and steel enterprise uses mostly using monoblock cast or
Forging.Overall manufacture grate plate must consider the combination properties such as the intensity, toughness, wearability of material simultaneously, can not pursue high abrasion
Property index.Prior art is in one layer of Wear-resistant, high-temperature resistant alloy of grate plate surface overlaying, and it is low with substrate combinating strength overlay cladding to be present,
The problem of easily coming off, built-up welding ply stress is larger, and anti-wear performance and impact resistance are poor.
The content of the invention
To solve the above problems, the utility model, which provides a kind of matrix alloy plantation surface high antifriction layer carbon arc, melts heap comb
Plate body, concrete scheme are：
A kind of matrix alloy plantation surface high antifriction layer carbon arc melts heap grate plate body, including grate plate body, the table of the grate plate body
Face is evenly equipped with some planting grooves, and plantation alloy, the outside covering of the grate plate body and plantation alloy are welded with the planting groove
There is Wear-resistant, high-temperature resistant alloy cladding layer；The planting groove is bar-shaped trough, and some planting grooves are distributed in grate plate body surface face in array,
The length direction of the planting groove is consistent with the length direction of grate plate body.
Further, the section of the planting groove is V-arrangement, and V-Bottom portion is arc, and the opening angle of V-arrangement is 30~50 degree.
Further, the depth of the planting groove is 8~15mm, and the A/F of planting groove is 10~20mm, planting groove
Length be 160~200mm.
Further, the depth of the planting groove is 10mm, and the A/F of planting groove is 15mm, and the length of planting groove is
185mm。
Further, the horizontal spacing of adjacent planting groove and longitudinal pitch are 5~20mm.
Further, the thickness of the alloy cladding layer is 1~5mm.
Further, the alloy cladding layer be containing chromium, niobium, molybdenum, boron high-wear-resistant alloy.
Beneficial point of the present utility model is：This programme is by offering some and grate plate body length on the surface of grate plate body
The consistent planting groove in direction, the welding plantation alloy in planting groove, then at grate plate body and the surface graphite electrode of plantation alloy
High-wear-resistant alloy compacting powder agglomates of one layer of the arc-melting containing chromium, niobium, molybdenum, boron, brings up to the crusher surface hardness of grate plate body
More than HRC62-65.The planting groove of this programme is the bar-shaped trough of cross direction profiles, and its Section Design is V-arrangement, the consideration reasonable in design
For single roll crusher when carrying out broken, mineral aggregate is to the impact force direction in grate plate body surface face, so that the combination for obtaining optimal is strong
Degree, it can significantly extend the service life of grate plate.
