Description
Technical field
The present invention relates to a kind of Settled breadth machine module and manufacture method thereof, particularly the wear-resisting module of a kind of large lateral pressure fixed-width pressure machine and manufacture method thereof, belong to Settled breadth machine module technical field.
Background technology
Large lateral pressure fixed width (Sizing Press is called for short SP) is an on-line width adjustment technology, has become an important new technology in modern hot rolled strip production, and it is the important new installation for slab being carried out to disposable large size side pressure.The main application of fixed-width pressure machine is that wide requirement customizes thick incoming slab width according to different production boards, be specially adapted to the few and occasion of producing again the wide production board of multiple different plate of continuously cast bloom specification, can effectively reduce former material base width specifications and continuously cast bloom width adjustment time and number of times, improve continuous caster output and productivity, reduce slab tank farm stock, simplify slab yard management and rolling scaduled, be convenient to produce in time the various width specifications band steel that meet user's needs.
Due to large lateral pressure fixed-width pressure machine pat to as if the steel billet that just taken out from process furnace, its samming reaches more than 1100 DEG C, under high loading, high temperature action condition, also will be subject to the effect that high frequency is impacted.Therefore, the working condition of fixed-width pressure machine module is extremely severe.This just requires the working lining of fixed-width pressure machine module to have good high temperature resistant fatigue property, high temperature resistant impact property, high temperature wear resistant performance, and this has proposed very harsh requirement to the over-all properties of material beyond doubt.But at present, the working face of fixed-width pressure machine module usually there will be large-area crackle.When crackle is more, if change not in time module, will on working face, there is the phenomenon of " surfacial spalling ", produce and bring major hidden danger to steel rolling.
In order to improve the work-ing life of large lateral pressure fixed-width pressure machine module, Japanese Patent JP2002194478A discloses the cast iron materials for Settled breadth machine module, its composition comprises by weight percentage: C:3.2 ~ 4.2%, Si:1.0 ~ 2.5%, Mn:0.1 ~ 0.6%, below P:0.10%, below S:0.02%, below Cr:0.15%, Mg:0.04 ~ 0.10%, Fe surplus, in described structure, more than 15% area ratio crystallization graphite, graphite granule particle diameter accounting for more than 50% more than 100 μ m in described kish of separating out, but in the cast iron materials that this patent provides, contain too much inclusion, seriously affect the performance of cast iron, especially reduce plasticity and toughness, cause being prone to crackle and peeling off in module use.Chinese patent CN102168224A also discloses a kind of Settled breadth machine module, described Settled breadth machine module is processed cast molding by spheroidal graphite cast iron, it is characterized in that: described spheroidal graphite cast iron comprises the composition of following mass percent: C:3～3.9%, Si:1.5～2.2%, Mn:0.3～0.5%, P≤0.04%, S≤0.012%, Cr < 0.3%, Ni:1.5 ~ 2.3%, Mo:0.4 ~ 0.6%, rare earth element: 0.08～0.25%, Fe surplus.This invention provides in module material and contains more expensive nickel, molybdenum element, also has the deficiency of the low and poor toughness of intensity.Chinese patent CN202061891U also discloses a kind of Settled breadth machine module, and the working face of its back side module is made up of three inclined-planes and a curved surface; The first inclined-plane and horizontal angle of cut α
