Description
Technical field
The utility model relates to field of cement production, especially relates to a kind of breaker roll playing chamotte crushing effect.
Background technology
Cement producing line grate-cooler belongs to Thermal Equipment, mainly plays cooling, conveying, recuperation of heat, broken effect to the material from rotary kiln.Material crushing device is middle kibbler roll, and main broken is extruded mutually by breaking ring on roll shaft.
As shown in Figure 3, the breaking ring crushing teeth positional alignment of existing grate-cooler is neat and tooth depth is equal, and breaking capacity can not meet the demands.Simultaneously due to the restriction of current material, use middle serious wear, the life-span is short, frequently need change breaking ring, greatly reduce production efficiency, improve production cost.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of breaker roll, and object improves chamotte crushing ability.
To achieve these goals, the technical scheme that the utility model is taked is:
Described breaker roll, comprise roll shaft and be arranged on the breaking ring on roll shaft, described breaking ring comprises the crushing teeth that is located at ring body outer rim and the symmetrical keyway being located at ring body inner edge, and each crushing teeth tooth depth is different, the center between described keyway not with the center superposition of each pair of crushing teeth.
Mutually stagger in the crushing teeth position of adjacent breaking ring and tooth depth is different.
Described breaking ring has two kinds, a kind of center line of keyway of breaking ring overlaps with the center line of at least one crushing teeth, the keyway of another kind of breaking ring does not overlap with the center line of crushing teeth, and the crushing teeth number of two kinds of breaking rings is equal, and two kinds of breaking rings are disposed on described roll shaft.
Described crushing teeth top surface heap is welded with wearing layer.
Each alloying element quality proportioning of described wearing layer material is: C:0.38 ~ 0.46%, Si:1.2 ~ 2.1%, Mn:1.0 ~ 1.6%, P :≤0.035%, S :≤0.035%, Ni:9 ~ 12%, Cr:26 ~ 28%, Mo:0.3 ~ 0.5%, N:0.8 ~ 1.2%, Re:0.7 ~ 1.0%.
Described breaking ring is high-wear-resistancecast cast steel part, and in its material, each alloying element quality proportioning is: C:0.12 ~ 0.15%, Si:0.8 ~ 1.1%, Mn :≤1%, P :≤0.03%, S :≤0.03%, Ni:12 ~ 15%, Cr:19 ~ 22%, Mo:0.3 ~ 0.5%, N:0.8 ~ 1.2%.
Adopt technique scheme, what the breaking ring tooth depth difference on adjacent roll shaft improve the broken grog of breaker roll gulps down the ability of pulling and breaking capacity, improves production efficiency and economic benefit.
Stagger and the different breaking capacity further increasing breaker roll of tooth depth in the crushing teeth position of adjacent breaking ring.Add and only need change breaking ring keyway position man-hour and just can realize, process simple and convenient
Wearing layer improves the anti-wear performance of breaker roll, extends the service life of breaker roll, improves efficiency, reduce cost.
The improvement of wearing layer material and breaking ring material effectively improve breaking ring in working order under anti-wear performance, extend the service life of breaker roll further.

Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, be described in further detail detailed description of the invention of the present utility model, to help, those skilled in the art conceives utility model of the present utility model, technical scheme has more complete, accurate and deep understanding.
As shown in Figure 1 and Figure 2, the utility model provides a kind of breaker roll, comprise roll shaft and be arranged on the breaking ring on roll shaft, breaking ring comprises the crushing teeth 1 and the symmetrical keyway 2 being located at ring body inner edge that are located at ring body outer rim, each crushing teeth 1 tooth depth is different, the center between keyway 2 not with the center superposition of each pair of crushing teeth 1.
Breaking ring has two kinds, a kind of center line of keyway 2 of breaking ring overlaps with the center line of at least one crushing teeth 1, the keyway 2 of another kind of breaking ring does not overlap with the center line of crushing teeth 1, and crushing teeth 1 number of two kinds of breaking rings is equal, and two kinds of breaking rings are disposed on described roll shaft.As long as two kinds of breaking rings, adding change in man-hour keyway 2 Working position, need not arrange new processing tool and change operation, therefore save manpower and reduce costs.
Breaking ring is by the positioning key location and installation on roll shaft, and mutually stagger in crushing teeth 1 position of adjacent breaking ring and tooth depth is different.Breaking ring minimum clearance on adjacent roll shaft is 20mm, and during normal work, tooth top and tooth top misplace.The breaking capacity of broken grog and gulp down the ability of pulling and improve all thus.
Described breaking ring is high-wear-resistancecast cast steel part, and in its material, each alloying element quality proportioning is: C:0.12 ~ 0.15%, Si:0.8 ~ 1.1%, Mn :≤1%, P :≤0.03%, S :≤0.03%, Ni:12 ~ 15%, Cr:19 ~ 22%, Mo:0.3 ~ 0.5%, N:0.8 ~ 1.2%.
Crushing teeth 1 top surface heap is welded with wearing layer 3.Each alloying element quality proportioning of wearing layer 3 material is: C:0.38 ~ 0.46%, Si:1.2 ~ 2.1%, Mn:1.0 ~ 1.6%, P :≤0.035%, S :≤0.035%, Ni:9 ~ 12%, Cr:26 ~ 28%, Mo:0.3 ~ 0.5%, N:0.8 ~ 1.2%, Re:0.7 ~ 1.0%.
Add appropriate nickel in new material to improve the intensity of steel, good plasticity and toughness can be kept again, at high temperature have antirust and temperature capacity.Utilize chromium can significantly improve intensity, hardness and wearability, strengthen non-oxidizability and corrosion resistance simultaneously.The molybdenum added can make the grain refinement of steel, improves quenching degree and thermostrength, keeps enough intensity and creep resisting ability when high temperature; Nitrogen can improve the intensity of steel, low-temperature flexibility and weldability, increases aging sensitivity.By controlling the compositional range of each alloying element, both ensure that high-wear-resistancecast cast steel part anti-wear performance, having improved its service life, having in turn ensure that the processability of spray, prevented its processing cost excessive, be unfavorable for processing.
Wearing layer 3 material then improves the constituent content of Si, Mn further, strengthens anti-wear performance, more with the addition of appropriate rhenium element, can crystal grain thinning, controls the formation of sulfide, effectively improves hardness and the anti-wear performance of wearing layer 3.Thus effectively improve the service life of breaking ring, avoid significantly improving production cost simultaneously.
Casting technique is first adopted to cast out breaking ring blank during manufacture, by crushing teeth on breaking ring 1 periphery along the circumferential direction overall processing fall certain thickness, ensure overlaying surface flat smooth, use special purpose machinery by high-abrasive material heat fused, heap is soldered to crushing teeth 1 top surface, is finally polished flat by facing surface.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
