Description
Technical field
The utility model relates to a kind of abrasion-proof backing block, particularly a kind of composite abrasion-proof inner plate.
Background technology
Rolling mill generally includes support and is arranged on the roll on this support, and is arranged on the bearing limited by bearing block of roll two axle heads.Due to rolling mill operationally, rolled piece generation plastic deformation, the size of rolled piece all can change on three-dimensional, can move up and down under the drag effect that roll or working roll are produced at deformation of rolled wire, and roll is in the process of movement, can produce between bearing block outer surface and stent inner surface and rub, this rubbing action can cause bearing block and support premature breakdown.In the prior art, for preventing bearing block and support premature breakdown, usually at bearing block outer surface, one piece of abrasion-proof backing block being installed, at stent inner surface, one piece of abrasion-proof backing block being also installed, being commonly called as memorial archway liner plate.
But in prior art, the liner plate on above-mentioned metallurgy rolling mill is made primarily of general steel plate or same tool steel plate.Although the liner plate low price that general steel plate is made, because its hardness is low, not wear-resisting, cause liner plate in use easily to damage, service life is short.And although the liner plate hardness that same tool steel plate is made is high, wearability strong, expensive.
Utility model content
Goal of the invention of the present utility model is: the problems referred to above existed for prior art, provide the composite abrasion-proof inner plate that the good anti shock and vibration ability of a kind of low price, wearability is good.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of composite abrasion-proof inner plate, comprises the installation base surface and working face that are complex as a whole; The Brinell hardness HB of described installation base surface is 70 ~ 100; The Rockwell hardness HRC (i.e. 52≤HRC≤62) between 52 ~ 62 of described working face, surface roughness > 1.6(or=1.6), and the case depth >=5mm of described working face.The wear-resisting composite liner of said structure, can have more actual needs polishing, cast the liner plate of various compound actual needs.Composite abrasion-proof inner plate of the present utility model, by the working face with high-wear resistance is combined with the installation base surface with high impact-resistant vibration ability, wearability and the anti shock and vibration ability of composite abrasion-proof inner plate entirety can be improved, composite liner is made to reach the mechanical property requirements to abrasion-proof backing block such as milling train and bearing block, extend the service life of abrasion-proof backing block, most importantly can reduce abrasion-proof backing block damage and cause the impaired probability broken down of milling train.Also greatly reduce on the consumption of same tool steel plate simultaneously, abrasion-proof backing block can also be avoided frequently to change the workload brought.
As preferred version of the present utility model, when the thickness of described composite abrasion-proof inner plate is 20 ~ 35mm, the thickness of described working face and the Thickness Ratio of described installation base surface are 1:3 ~ 8; When the thickness of described composite abrasion-proof inner plate is 35 ~ 50mm, the thickness of described working face and the Thickness Ratio of described installation base surface are 1:5 ~ 8.The Thickness Ratio of working face and installation base surface in above-mentioned abrasion-proof backing block, the overall mechanical properties of composite abrasion-proof inner plate is best.Preferred, when the thickness of described composite abrasion-proof inner plate is 20 ~ 35mm, the thickness of described working face and the Thickness Ratio of described installation base surface are 1:3.Preferred, when the thickness of described composite abrasion-proof inner plate is 35 ~ 50mm, the thickness of described working face and the Thickness Ratio of described installation base surface are 1:5.
As preferred version of the present utility model, described working face is martensitic stainless steel or same tool steel plate.
As preferred version of the present utility model, described installation base surface is general steel plate.
As preferred version of the present utility model, described working face and described installation base surface adopt Explosion composite method to be complex as a whole.General Requirements recombination rate is for reaching more than 98%.Working face and installation base surface adopt the mode of Explosion composite to be combined as a whole, and faying face does not exist weld seam, but the form of overall engrail metallurgical binding state, the overall mechanical properties meeting abrasion-proof backing block is good.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
1, composite abrasion-proof inner plate of the present utility model, by the working face with high-wear resistance is combined with the installation base surface with high impact-resistant vibration ability, wearability and the anti shock and vibration ability of composite abrasion-proof inner plate entirety can be improved, composite liner is made to reach the mechanical property requirements to abrasion-proof backing block such as milling train and bearing block, extend the service life of abrasion-proof backing block, most importantly can reduce abrasion-proof backing block damage and cause the impaired probability broken down of milling train.Also greatly reduce on the consumption of same tool steel plate simultaneously, abrasion-proof backing block can also be avoided frequently to change the workload brought.
2, composite abrasion-proof inner plate of the present utility model, working face and installation base surface adopt the mode of Explosion composite to be combined as a whole, and faying face does not exist weld seam, and the overall mechanical properties meeting abrasion-proof backing block is good.
