Description

A kind of wear-resisting type hoist roller

Technical field

The present invention relates to a kind of hoist roller, particularly to a kind of wear-resisting type hoist roller.

Background technology

It is known that reel is the parts in crane for lay winding wire ropes, and in actual use, crane The friction occurred when reel and wirerope-winding is very big, and traditional spool body is after rubbed, and its surface often occurs bigger Abrasion, then when this mandrel surface lay winding wire ropes, the phenomenon that wirerope-winding loosens often occurs, safety easily occurs Accident.

Summary of the invention

The technical problem that present invention mainly solves is to provide a kind of wear-resisting type hoist roller, it is possible to possess have extremely strong resistance to Mill performance, service life is long, prevents mandrel surface from being caused wirerope-winding to occur to loosen by steel rope abrasion.

For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of wear-resisting type crane volume Cylinder, including: cylinder and brushing at the wear-resistant alloy layer of described drum surface, described wear-resistant alloy layer includes following mass fraction Composition:

Carbon accounts for 2.3-2.5%, and silicon accounts for 1.6-2.4%, and manganese accounts for 0.8-1.0%, and molybdenum accounts for 0.6-0.8%, and titanium accounts for 0.9-1.5%, and nickel accounts for 0.6- 0.8%, rare earth element accounts for 0.3-0.5%, phosphorus be less than 0.04%, sulfur be less than 0.04%, nitrogen be less than 0.04%, surplus be ferrum and Inevitably impurity；

Described rare earth element is made up of cerium and lanthanum mixing, calculates according to mass percent, and the content of described cerium accounts for 55-65%, described The content of lanthanum accounts for 35-45%.

In a preferred embodiment of the present invention, the thickness of described wear-resistant alloy layer is 0.5-1.5mm.

In a preferred embodiment of the present invention, described inevitable impurity is sulfide, phosphide or nitride Any one or more mixes.

In a preferred embodiment of the present invention, in described rare earth element, the concrete quality proportioning of composition is: described cerium Content accounts for 60%, and the content of described lanthanum accounts for 40%.

The invention has the beneficial effects as follows: the present invention brushes the wear-resisting of one layer of high-temperature fusion by using in hoist roller surface Aluminium alloy, after solidification to be cooled, forms, on hoist roller top layer, the wear-resistant alloy layer that a wear-resisting type is extremely strong such that it is able to possess Having extremely strong anti-wear performance, service life is long, prevents mandrel surface from being caused wirerope-winding to occur to loosen by steel rope abrasion.

Detailed description of the invention

Below presently preferred embodiments of the present invention is described in detail so that advantages and features of the invention can be easier to by It will be appreciated by those skilled in the art that thus protection scope of the present invention is made apparent clear and definite defining.

Embodiment 1:

A kind of wear-resisting type hoist roller is including: cylinder and brushing at the wear-resistant alloy layer of described drum surface, described wear-resisting Alloy-layer includes the composition of following mass fraction:

Carbon accounts for 2.3%, and silicon accounts for 2.4%, and manganese accounts for 0.8%, and molybdenum accounts for 0.8%, and titanium accounts for 0.9%, and nickel accounts for 0.8%, and rare earth element accounts for 0.3%, and phosphorus is not More than 0.04%, sulfur is less than 0.04%, and nitrogen is less than 0.04%, and surplus is ferrum and inevitable impurity；

Described rare earth element is made up of cerium and lanthanum mixing, calculates according to mass percent, and the content of described cerium accounts for 55%, described lanthanum Content account for 45%.

Embodiment 2:

Carbon accounts for 2.5%, and silicon accounts for 1.6%, and manganese accounts for 1.0%, and molybdenum accounts for 0.6%, and titanium accounts for 1.5%, and nickel accounts for 0.6%, and rare earth element accounts for 0.5%, and phosphorus is not More than 0.04%, sulfur is less than 0.04%, and nitrogen is less than 0.04%, and surplus is ferrum and inevitable impurity；

Described rare earth element is made up of cerium and lanthanum mixing, calculates according to mass percent, and the content of described cerium accounts for 65%, described lanthanum Content account for 35%.

Embodiment 3:

Carbon accounts for 2.4%, and silicon accounts for 2.0%, and manganese accounts for 0.9%, and molybdenum accounts for 0.7%, and titanium accounts for 1.2%, and nickel accounts for 0.7%, and rare earth element accounts for 0.4%, and phosphorus is not More than 0.04%, sulfur is less than 0.04%, and nitrogen is less than 0.04%, and surplus is ferrum and inevitable impurity；

The preparation technology of the present invention a kind of wear-resisting type hoist roller is as follows:

(1), melting: weigh each raw material according to aforementioned proportion, carry out high temperature fusion treatment in being mixed input high-temperature smelting pot, obtain To hybrid metal liquid；

(2), casting: defeated after using conveyer device that by condenser, above-mentioned hybrid metal liquid is formed melted thick molten metal Deliver to hoist roller surface, slow slewing crane reel so that hybrid metal liquid is brushed uniformly at hoist roller table Face, final prepared wear-resisting type hoist roller.

Wherein, the thickness of described wear-resistant alloy layer is 0.5-1.5mm；Described inevitable impurity is sulfide, phosphatization Any one or more mixing of thing or nitride.

Being different from prior art, the present invention brushes the wear-resisting of one layer of high-temperature fusion by using in hoist roller surface Aluminium alloy, after solidification to be cooled, forms, on hoist roller top layer, the wear-resistant alloy layer that a wear-resisting type is extremely strong such that it is able to possess Having extremely strong anti-wear performance, service life is long, prevents mandrel surface from being caused wirerope-winding that pine occurs by steel rope abrasion Dynamic..
