The invention discloses a wear-resisting metallic liner plate with hole patterns. The wear-resisting metallic liner plate comprises a plate body (1), wherein a wear-resisting layer is arranged outside the plate body (1), hole patterns (4) are formed in a direction vertical to a working surface (5) of the plate body (1), and a wear-resisting layer serves as a hole pattern wall of each hole pattern (4) and comprises a quench-hardened layer (2) and a tempered layer (3) which are distributed in a direction vertical to the surface of the corresponding hole pattern wall in sequence. A manufacturing method of the wear-resisting metallic liner plate with the hole patterns comprises the steps of: machining the hole patterns (4) distributed on the entire working surface (5) of the plate body (1) along the direction vertical to the working surface (5) of the plate body (1), and tempering and quenching the plate body (1) in sequence. The invention has the beneficial effects that: the wear-resisting layers of the hole patterns and the wear-resisting layer of the plate body constitute a wear-resisting framework structure of the metallic liner plate together, so that the hardness and the wear resistance of the liner plate are increased, the service life of the liner plate disclosed by the invention is prolonged by 1.5-2 times compared with that of the traditional liner plate, and the consumption level of materials used for manufacturing the metallic liner plate is lowered by 1/5-1/3.
Description
Technical field
The present invention relates to abrasion-resistant metal liner plate technical field, particularly a kind of containing pass abrasion-resistant metal liner plate and manufacture method thereof.
Background technology
The metal backing (except magnetic liner plate) using in the world at present, wearing face is plane, cambered surface or local crowning or it is compound.For improving metal backing wearability and case hardness, adopt the modified method that adds quenching, as shown in Figure 1, at the wearing face of liner plate plate body 1, along the direction perpendicular to liner plate wearing face, form thickness and be less than the quench-hardened case 2 of 3mm and the texturizing layer 3 that thickness is less than 30mm.In use, after quench-hardened case 1 wearing and tearing, the wearability fast reducing of metal backing, after texturizing layer 3 wearing and tearing, liner plate is scrapped very soon, is greater than in 50mm situation performance especially remarkable at liner plate thickness.Therefore existing abrasion-resistant metal liner plate exists the problem of hardness and wearability sharp-decay after using certain hour, causes that abrasion-resistant metal liner plate service life is short, consumption of materials is large.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, provide a kind of greatly improve abrasion-resistant metal liner plate service life, reduce production costs again simultaneously containing pass abrasion-resistant metal liner plate and manufacture method thereof.
Object of the present invention is achieved through the following technical solutions: containing pass abrasion-resistant metal liner plate, comprise plate body, the outer surface of plate body is wearing layer, in the direction perpendicular to plate body working surface, offers pass, pass is distributed in whole working surface, and the pass wall of described pass is wearing layer.
Described pass wall wearing layer comprises along the quench-hardened case and the texturizing layer that distribute successively perpendicular to pass wall surface direction.
Described pass is through hole or the blind hole that runs through plate body.
Described wearing layer forms the wear-resisting skeleton structure of liner plate overall network shape.
Containing the manufacture method of pass abrasion-resistant metal liner plate, it comprises the following steps:
A, along perpendicular to the direction of plate body working surface, on plate body, process the pass that is distributed in whole working surface;
B, to being processed with the plate body of pass, carry out whole modifier treatment, at plate body surface and pass wall surface formation texturizing layer;
C, again plate body is carried out to integral quenching processing, at plate body surface and pass wall surface formation quench-hardened case.
The present invention has the following advantages:
The present invention offers pass on plate body, the wearing layer of pass wall and the wearing layer of plate body form the wear-resisting skeleton structure of metal backing jointly, the wear-resisting network structure of metal backing being integrated with skeleton that makes that liner plate has in each thick layer that a quenched and tempered state metal level by wide 0.2 to 3mm harden state metal level and wide 5 to 25mm forms, the hardness and the wearability that keep metal backing, more existing liner plate improves 1.5 to 2 times service life, and manufactures the consumption of materials reduction by 1/5 to 1/3 of liner plate.

Fig. 1 is the structural representation of existing abrasion-resistant metal liner plate
Fig. 2 is structural representation of the present invention
Fig. 3 is that Fig. 2 is along the cutaway view in A-A cross section
In figure, 1-plate body, 2-quench-hardened case, 3-texturizing layer, 4-pass, 5-working face.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described:
As shown in Figure 2 and Figure 3, containing pass abrasion-resistant metal liner plate, comprise plate body 1, the outer surface of plate body 1 is wearing layer, offers pass 4 in the direction perpendicular to plate body 1 working surface 5, and pass 4 is distributed in whole working surface 5, pass 4 runs through plate body 1, and the pass wall of pass 4 is wearing layer.
Described pass wall wearing layer comprises along the quench-hardened case 2 and the texturizing layer 3 that distribute successively perpendicular to pass wall surface direction.
Described quench-hardened case 2 thickness are 0.2～3mm, and described texturizing layer 3 thickness are 5～25mm.
Described wearing layer forms the wear-resisting skeleton structure of liner plate overall network shape.
Manufacture method containing pass abrasion-resistant metal liner plate comprises the following steps:
A, first along perpendicular to the direction of plate body 1 working surface 5, on plate body 1, process shape, the sizeable pass 4 that is distributed in whole working surface 5, carrying size, mode during depending on plate body 1 material, blank state and use, can adopt the method for casting, die forging or processing, described pass 4 can adopt circle, polygon and closed curve or its combination, and pass 4 can be through hole or the blind hole that runs through plate body 1;
B, then according to metal backing material behavior, to being processed with the plate body 1 of pass 4, carry out whole modifier treatment, at plate body 1 surface and pass wall surface formation texturizing layer 3;
C, according to metal backing material behavior, plate body 1 is carried out to integral quenching processing again, at plate body 1 surface and pass wall surface formation quench-hardened case 2.
So can form the wear-resisting skeleton structure jointly being formed by the wearing layer of pass wall and the wearing layer of plate body 1, the wear-resisting network structure of abrasion-resistant metal liner plate being integrated with skeleton that makes that abrasion-resistant metal liner plate has in each thick layer that a quenched and tempered state metal level by wide 0.2 to 3mm harden state metal level and wide 5 to 25mm forms, realizes with network-like wear-resisting skeleton structure bearing load, shock resistance and wearing and tearing.
During use, can in plate body 1 bottom, add as required support or pass 4 employing blind hole modes to maintain material, in pass 4, by required fragmentation or levigate ore charge automatic filling, realize material abrasive material.
