Problems solved by technology

People initially used wear-resistant cast iron casting liners, but the wear resistance was poor; later people used hard alloy surfacing wear-resistant layer or brazing hard alloy wear-resistant blocks to make wear-resistant liners, although the wear resistance has been improved. A certain improvement, but the hard alloy surfacing wear-resistant layer has poor impact resistance and high temperature resistance; the brazing hard alloy wear-resistant block consumes non-ferrous metal-copper, and the cost is high
In addition, since there are many transverse continuous soft belts on the surface of the lining plate of the brazed carbide wear-resistant block, when the material moves laterally, the continuous soft belt is easily worn, which affects the service life of the entire wear-resistant lining

Embodiment Construction

[0030] Below in conjunction with accompanying drawing, further illustrate the present invention through embodiment.

[0031] In the embodiment, the lining plate produced in this embodiment is used for the lining plate of the distribution chute of the ironmaking blast furnace, and the manufacturing method of the embedded casting hard alloy wear-resistant lining plate includes the following steps:

[0032] ①The shape of the hard alloy wear-resistant block 1 is a hexagonal star, which is fixed on the bracket 5. The matching fixing bolt holes 3 are set on the hard alloy block and the bracket, and are fixedly connected by bolts and nuts. The hard alloy wear-resistant block Covering the entire surface of the bracket, there is a shape-locked space 2 between the hard alloy wear-resistant blocks, which is in the shape of a hexagonal star; the edge of the hexagonal star-shaped hard alloy wear-resistant block 1 has a certain slope, which becomes a slope shape Locking 4, the range of incl...

Abstract

The present invention relates to antiwear lining plate with embedded hard alloy for industrial crushing, sieving, conveying, storing and transporting apparatus and its making process. The technological scheme includes the following steps: fixing antiwear hard alloy blocks on some support, setting the support with antiwear hard alloy blocks on the casting sand mold and pre-heating, casting liquid metal, naturally cooling, cleaning sand and air cooling, eliminating the support, and surface cleaning to obtain antiwear lining plate with embedded hard alloy. The antiwear lining plate with embedded hard alloy has high impact strength, high wear resistance, high heat resistance, long service life and other advantages, and the technological process is reasonable, novel and low in cost.

Description

Technical field: [0001] The invention relates to an industrially used hard alloy wear-resistant liner and a manufacturing method thereof, in particular to an inlay-cast hard alloy wear-resistant liner and its Production Method. Background technique: [0002] In the industry, iron ore, sinter, coke, coal, limestone and other bulk materials are severely worn by abrasive particles, so wear-resistant liners (also called liners) are required on the corresponding crushing, screening, handling, storage, and transportation equipment sets) to prolong the service life of the equipment, such as silo linings for storing materials, chutes, pipes, truck linings, etc. for conveying materials. People initially used wear-resistant cast iron casting liners, but the wear resistance was poor; later people used hard alloy surfacing wear-resistant layer or brazing hard alloy wear-resistant blocks to make wear-resistant liners, although the wear resistance has been improved. A certain improvemen...
