Description

A kind of roll for diamond plate rolling
Technical field
The present invention relates to roll, especially a kind of roll of subcarbide, rolls for diamond plate.
Background technology
Diamond plate has many advantages, such as good appearance, anti-skidding, reinforcing performance, saving steel, in traffic, building, decoration The field such as decoration, equipment surrounding floor, machinery and shipbuilding is widely used, because of its unique configuration, building and machinery manufacturing industry Can replace the tablet of 4.0mm completely with the diamond plate of 2.5 ~ 3mm, it is per ton can saving steel 220kg, therefore, diamond plate has Wide market and application space.
At present, the production of diamond plate is formed using tandem mill rolling more.Since diamond plate amount of rolling is generally all smaller, steel mill Rolled after generally carving beans using the close precision rolling rear working roller scrapped, indivedual producers' meeting custom-made rolled diamond plates Roll, the material routinely selected include the materials such as pearlitic ductile iron, high nickel chromium triangle infinitely chilled ductile cast iron.
Since the materials such as the particularity of diamond plate rolling, pearlitic ductile iron, high nickel chromium triangle infinitely chilled ductile cast iron class were using Since carbide content itself is more in journey, carbide area fraction is general>20%, heat resistanceheat resistant is strong to be affected, body of roll decorative pattern The frequent cracked problem of beans, in order to ensure that decorative pattern beans are processed, hardness is generally relatively low（≤75HSD）.Such material is universal at the same time There are graphite-phase, belongs to soft phase, causes decorative pattern beans on microcosmic there are notch, while also reduce overall wearability.It is overall Happen occasionally using the problems such as above collapsing block, crackle, at the same it is generally shorter in the machine cycle, greatly reduce diamond plate rolling effect Rate.
The content of the invention
The technical problem to be solved in the invention is to provide a kind of roll for diamond plate rolling, can improve carbide Content and form, strengthen matrix performance, improve the hot-cracking resistance and wearability of roll, reduce and carve beans difficulty of processing, carry The efficiency of cleat plate rolling.
In order to solve the above technical problems, the technical solution adopted in the present invention is：
A kind of roll for diamond plate rolling, including roller core and roll working lining, the chemical constituent and its matter of roll working lining Amount percentage composition is C1.30 ~ 2.00%, Si0.60 ~ 1.00%, Mn0.80 ~ 1.10%, Cr11.00 ~ 18.00%, Ni0.80 ~ 1.30%, Mo0.90 ~ 2.00%, S≤0.03%, P≤0.05%, remaining is Fe and inevitable impurity.
Technical solution of the present invention further improvement lies in that：The chemical constituent of roll working lining further includes V and N, quality hundred Point content is V0.10 ~ 0.30%, N >=0.10%.
Technical solution of the present invention further improvement lies in that：V and N is by Metamorphism treatment and microalloy when outer layer is smelted What the mode of processing added.
Technical solution of the present invention further improvement lies in that：The mass ratio of Cr and C is 9 ~ 11:1.
Technical solution of the present invention further improvement lies in that manufacture method comprises the following steps：
A, smelt：Dispensing is carried out by the chemical constituent of roll working lining, is then smelted in induction furnace；
B, pour into a mould：Metal type cast roll working lining is used on centrifuge, treats to be in half curdled appearance on the inside of roll working lining When, metal mold and the sandbox for pouring into a mould core are merged, obtain roll casting mold；Core molten iron is handled through alterant and inovulant Afterwards, in from roll casting mold upper pouring to mould cavity, casting is obtained.
C, it is heat-treated：Casting is heat-treated.
Technical solution of the present invention further improvement lies in that：The temperature for pouring into a mould roll working lining is 1380 ~ 1420 DEG C, centrifugation Machine rotating speed is 740 ~ 780r/min, and temperature during core molten iron casting is 1390 ~ 1430 DEG C.
Technical solution of the present invention further improvement lies in that：Heat treatment temperature is 1100 ~ 1200 DEG C, processing time for 90 ~ 120min。
By adopting the above-described technical solution, the technological progress that the present invention obtains is：
A kind of roll for diamond plate rolling of the present invention, improves carbide content and form, enhances matrix Performance, improves the hot-cracking resistance and wearability of roll, reduces and carves beans difficulty of processing, greatly improves the effect of diamond plate rolling Rate.
The present invention obtains the carbide content in roll and form by designing rational alloying component and casting technique Basic improvement has been arrived, and matrix is strengthened, and the comprehensive performance of roll has obtained the raising of essence, more suitable Rolling for diamond plate.Design and corresponding processing technology of the present invention by alloying component, can make graphite area fraction Control as 8 ~ 17%, it is higher to solve the roll carbide content of traditional preparation methods production, the strong poor-performing of heat resistanceheat resistant, body of roll flower The problem of line beans are often cracked.And since Cr and C mass is higher（9~11:1）, carbide content is by traditional material M3C-type Carbides Transformation is M7C3Type carbide, wearability are improved；Form is changed into block Dispersed precipitate from net bulk, interrupts The passage that crackle is extended along carbide, is improved heat crack resistance.
The present invention is poured into a mould using two layers of centrifugal compound mode, and three layers of centrifugal compound are used with traditional high ferrochrome roll Mode is compared, and few cast once, shortens production technology, reduces cost, and two layers of centrifugation cooling is more held than the three leafing hearts Easily, effect is more preferable, can ensure the hot-cracking resistance and wearability of roll.Handled at the same time by differential quenching, obtain martensite base Body, the pearlite and bainite competency of more traditional tissue greatly improve, and are made that tissue prepares for the raising of comprehensive performance.
The present invention carries out the rotten and microalloy processing of V and N in hot-cracking resistance or more demanding wearability, during smelting, The V and N of addition can form V in the base（N）C-type hard particles, further enhance the protection to matrix, wearability and heat resistanceheat resistant Fragility can further improve.
The present invention is dissolved more Cr elements, matrix obtains by force by controlling the mass ratio of higher Cr and C in matrix Change.At the same time promote Mo elements with the precipitation ability of hard phase so that on matrix can the fine Mo particles of Dispersed precipitate, enhancing Protective effect to matrix.Reduce the exposed area of matrix so that roll surface quality and the quality of decorative pattern beans are filled Code insurance hinders.
The present invention realizes the raising of properties of product by the comprehensive function of carbide and matrix, avoids to the full extent Weakening of the conventional material higher carbon compound to processing performance, hardness highest can accomplish hardness 85HSD without influencing diamond plate Processing performance.
