Abstract
The utility model relates to a wear-resisting element in particular to a wear-resisting block with high resistance special for the spiral cylinder of the coal cutter (the spiral cylinder). The wear-resisting block employs a compound structure of a metal layer (1) and a carbide alloy particle enriched layer (2). The block is plate-like with one side surface of enriched carbide alloy particles (3). The utility model is poured by low-carbon steel liquid of high hardness carbide alloy particles in the cavity. The utility model has the advantage of low cost, high production efficiency, preventing the scouring of the particles in use and a high wear resistance as well as a good weldability for jointing to the wearing parts of the requiring steel works.
Description
Technical field
The utility model relates to wearing piece, is specially the wear-resistant block of a kind of Shearer Helical Drum (hereinafter to be referred as cylinder) with high-wearing feature.
Background technology
Because Shearer Helical Drum is the operating mechanism of the direct coal cutting of coal-winning machine, so its abrasion resistance and the key that is technology application life, progressively promote the use of in China, for improving the cylinder abrasion resistance, the wear-resistant block that China has a kind of carbide reactor that mixes to be soldered on the long strip type soft metal plate is used on cylinder, and easy layering comes off in the use, and because the restriction of welding procedure, the density of doping hard alloy particle is not enough, so anti-wear performance is poor.
The utility model content
The purpose of this utility model is to provide a kind of wear-resistant block, and is promptly wear-resisting, solderability is good again.
The technical solution of the utility model is:
Wear-resistant block is metallic matrix layer and hard alloy particle enriched layer composite construction.
Described composite construction is tabular, and the one side surface has intensive hard alloy particle.
Wear-resistant block is to utilize the hard alloy particle of high rigidity to pour into a mould the casting of low-carbon (LC) molten steel in die cavity to form, and its cost is low, the production efficiency height, and not threshing in the use it is soldered to needed steel component easily grinds the position high abrasion resistance is arranged, and solderability is fine.
The beneficial effects of the utility model:
1, because wear-resistant block is metallic matrix layer and hard alloy particle enriched layer composite construction, utilized the solderability of metallic matrix layer, and the abrasion resistance of hard alloy particle enriched layer, so promptly wear-resisting, solderability is good again.
2, because technology determines that rationally not only surface forming is good, and fusion is better, is difficult for threshing in the use.
3,, and,, higher anti-wear performance is arranged so the particle of carbide alloy is very close with higher temperature cast because cast steel is to smelt fast by intermediate frequency.
4, owing to adopt casting, so cost is low, waste product rate is low, and the production efficiency height.
5, because cost is low, it can increase the laying amount at the wear-resisting position of cylinder, makes the anti-wear performance of cylinder better, has also improved the market competitiveness of cylinder.
Description of drawings
Fig. 1 the utility model wear-resistant block structural representation.
Fig. 2 is the upward view of Fig. 1.
Among the figure, 1 metallic matrix layer; 2 hard alloy particle enriched layers; 3 hard alloy particles.
The specific embodiment
Shown in Fig. 1-2, the utility model wear-resistant block is the compound platy structure of metallic matrix layer 1 and hard alloy particle enriched layer 2, and the one side surface has intensive hard alloy particle 3.Hard particles such as WC, grain graininess are the 7-8 millimeter; Metallic matrix can be the good mild steel of solderability.
The utility model wear-resistant block is to utilize the hard alloy particle of high rigidity to pour into a mould the casting of low-carbon (LC) molten steel in die cavity to form, its cost is low, production efficiency height, not threshing in the use, it is soldered to needed steel component easily grinds the position high abrasion resistance is arranged, and solderability is fine.
Because the Shearer Helical Drum coal cutting is under the geology working condition of complexity, not only coal cutting normal wear, and unavoidably want folder rock in the cut coal seam, or top, base plate, very easily wearing and tearing, the particularly toothholder of the wide-angle tooth of installing on cylinder end plate face and the end plate and rib folder coal (rock) wearing and tearing, and press from both sides coal (rock) wearing and tearing between blade tail end and transporter chute, so reasonably arrange according to the situation of actual wear and the composite metal anti-abrasive material of this high-wear resistance will be improved the application life of cylinder greatly.Promptly reduce the down-hole maintenance, also improved coal-winning machine production efficiency.
Claims (2)
1, a kind of wear-resistant block is characterized in that: this wear-resistant block is the composite construction of metallic matrix layer (1) and hard alloy particle enriched layer (2).
2, according to the described wear-resistant block of claim 1, it is characterized in that: this wear-resistant block is tabular, and the one side surface has intensive hard alloy particle (3).
