Description
Technical field
The invention belongs to roll squeezer (high-pressure roller mill) field, more particularly to it is a kind of be used for building material cement, metallurgy, mine,
The wear-resistant roll surface of roll squeezer in the industry roll-in milling equipment such as coal, chemical industry.
Background technology
In the industries such as building material cement, metallurgy, mine, material powder is widely carried out using roll squeezer (high-pressure roller mill)
Mill, the life-span of roll surface directly influences production cost.
Current roll surface of roller press has following several forms：Hardfacing roll surface, chilled cast iron roll surface, composite casting roll surface with
And stud roll surface, wherein stud roll surface comparative lifetime is longer.But it is cylinder that stud roll surface, which uses stud, in roll surface matrix
It is upper beat stud hole (cylinder) need it is spaced apart, to ensure the fastness of stud and the installation of roll surface matrix, so stud
Between gap it is relatively large, the protection so to roll surface matrix is very limited, the abrasion of roll surface matrix with respect to stud faster so that
Limit the life-span of whole roll surface；Stud roll surface matrix needs certain wearability and hardness, and processing difficulties are improved and are fabricated to
This；Stud is connected by viscose glue, and roll surface must assure that and worked below uniform temperature, and otherwise viscose glue will fail, and stud is held
Easy stress is come off, and the use scope of roll surface is limited to a certain extent.Stud hole in stud and roll surface matrix uses viscose glue
It is connected, not easily assembling., it is necessary to heat stud and roll surface matrix to uniform temperature during dismounting, certain pulling force is added by post
Nail puller goes out, very inconvenient.
The content of the invention
It is an object of the invention to：A kind of armoring roll surface of wear-resistant solid matter is proposed, roll surface matrix is not easy to wear, to roll surface matrix
Material and processing request reduction, reduce cost of manufacture, roll surface wear resistence is good, and long lifespan, surface wear-resistant layer is hardly damaged, Ke Yi
Use, and easily load and unload at higher temperature.
The object of the invention is realized by following technical proposals：
A kind of armoring roll surface of wear-resistant solid matter, it is characterised in that：Including roll surface matrix, and it is fixed on the roll surface matrix
Wear-resistant armor layer, the wear-resistant armor layer is by several close-packed arrays and the dress that is secured by bolts on the roll surface matrix
First unit is constituted, and a armoring unit generally cone is made up of the positive six prismsby body on top and the cone of bottom.
Alternatively, the armoring unit is provided with bolt hole along central shaft.
Alternatively, it is correspondingly arranged on cone on the roll surface matrix and inlays pit and screwed hole.
Alternatively, the roll surface matrix is made up of high strength steel, and the armoring unit is made up of hard alloy.
Foregoing main scheme of the invention and its each further selection scheme can form multiple schemes with independent assortment, be this
The scheme that invention can be used and is claimed：Such as the present invention, each selection can be with other selection any combination, people in the art
Member can understand there are multiple combinations after the present invention program is understood according to prior art and common knowledge, be claimed by the present invention
Technical scheme, exhaustion is not done herein.
The course of work is：The armoring roll surface of the wear-resistant solid matter of the present invention, can effectively reduce the gap between plate armour, it is to avoid thing
Material is directly acted on roll surface matrix, and roll surface matrix is not easy to wear, roll surface matrix material and processing request is reduced, reduction is fabricated to
This, roll surface wear resistence is good, long lifespan；Single armoring unit is inlayed into roll surface matrix, roll surface matrix and list by conical structure
The stress of individual armoring unit operationally all will be more preferable, and there is mutually restriction between adjacent armoring unit, be hardly damaged, pass through spiral shell
Bolt, which is connected, to be used at a higher temperature, and easily loads and unloads, so as to effectively solve above-mentioned to deposit in the prior art
The problem of；Armoring unit is embedded on roll surface matrix in compact arranged mode by conical structure, blending bolt and roller
Face matrix is connected, wear-resistant armoring easily handling, and effectively avoid material from directly being contacted with roll surface matrix, and roll surface stress
More preferably, so as to protect roll surface well, roll surface wear resistence is good, long lifespan.
Beneficial effects of the present invention：
1. due to avoiding the direct effect of material and roll surface matrix, the hardness requirement and wearability of roll surface matrix require drop
It is low, so as to reduce the raw material requirement of roll surface matrix and reduce corresponding Technology for Heating Processing process, it is also easy in roll surface
Processed on matrix.
2. it is single it is armoring inlayed by conical structure into roll surface matrix, roll surface matrix and it is single it is armoring operationally by
Power all will be more preferable, and there is mutually restriction between adjacent plate armour, be hardly damaged, being bolted fixation can be in higher temperature
Under use, and easily load and unload.
3. due to avoiding the direct effect of material and roll surface matrix, the service life of roll surface is improved, is effectively increased
Operation rate, so as to reduce the manufacturing cost of roll surface.
