Accompanying drawing explanation
Fig. 1 is the microstructure figure of multicomponent alloy liner plate of the present invention.
Detailed description of the invention
Being described principle and the feature of the present invention below in conjunction with accompanying drawing, example is served only for explaining the present invention, and Non-for limiting the scope of the present invention.
Be suitable to, as it is shown in figure 1, a kind of, the multicomponent alloy liner plate that semi-autogenous mill uses, melt iron process, described The component of melt iron mass percent is: carbon 1.1%-1.3%, silicon 0.3%-0.8%, manganese 11%-14%, chromium 0.8%- 1.5%, molybdenum 0.10%-0.5%, vanadium 0.3%-0.7%, titanium 0.05%-0.2%, phosphorus ＜ 0.05%, sulfur ＜ 0.03%.These are many It is broken that unit's alloy lining solves high carbon chromium molybdenum alloy liner plate used by conventional semi-autogenous mill liner plate, the wearability poor use cycle The shortcoming that shorter needs are frequently changed.This kind of material liner plate is applicable to large-scale semi-autogenous mill liner plate.This material is large-scale by half to meet Autogenous grinding liner plate, to wearability, the requirement of obdurability, optimizes liner plate chemical composition, and potassium steel carries out alloying, add vanadium, The alloy such as titanium, molybdenum suppresses the shortcoming that potassium steel ductility is big, and have employed unique Technology for Heating Processing, it is carried out disperse strong Change processes, and makes liner plate impact flexibility 65-136J/cm2, use hardness to reach 52-58HRC, the key technical indexes reaches domestic and international The advanced level of like product, price but reduces by more than 20% than high carbon chromium molybdenum alloy liner plate, can meet quality and the property of user Can requirement.
Above-mentioned multicomponent alloy liner plate production status is the liner plate of heat treatment, including following machining process:
(a) casting: melt iron is cast in molding in the resin self-setting sand die cavity accomplished fluently in advance, removes after molding Dead head makes as cast condition liner plate.
Wherein, melt iron tapping temperature is 1450～1480 DEG C, and pouring temperature is 1380～1420 DEG C.Resin self-setting sand Moulding process, removes dead head and makes as cast condition liner plate after molding.Suitably tapping temperature and pouring temperature, beneficially molten iron punching Type；If pouring temperature is too low, the problems such as foundry goods rarefaction defect easily occur；If temperature is too high, cast structure easily occurs The problem such as thick.
Described melt iron includes the component of following mass percent: carbon 1.1%-1.3%, silicon 0.3%-0.8%, manganese 11%-14%, chromium 0.8%-1.5%, molybdenum 0.10%-0.5%, vanadium 0.3%-0.7%, titanium 0.05%-0.2%, phosphorus ＜ 0.05%, sulfur ＜ 0.03%, surplus is ferrum.
B as cast condition liner plate is carried out heat treatment by (): be incubated after being heated up by as cast condition liner plate, quench afterwards, last precipitation process.
What as cast condition liner plate was incubated after heating up concretely comprises the following steps: the as cast condition liner plate that will make loads heat-treatment furnace, heats up Isothermal holding, is carried out time below 650 DEG C with the ramp of 50～80 DEG C/min, is warming up to 650 DEG C and is incubated 3h, 650 With the ramp of 100～120 DEG C/min time more than DEG C, be warming up to austenitizing insulation temperature 1050～1070 DEG C, insulation Time be 5～6h.Suitably temperature retention time and holding temperature, is conducive to the most tiny austenite crystal to be formed；If Time is too short, temperature is too low, easily occurs that austenitizing is incomplete or the problem such as austenitizing is uneven；If overlong time, Temperature is too high, the problem that austenite crystal is thick easily occurs.
Quenching, the concretely comprising the following steps of precipitation process: again rise with the speed of 50～80 DEG C/min after as cast condition liner plate is quenched Temperature, is warmed up to 400 DEG C and is incubated 4h when 400 DEG C, and last air cools down, and multicomponent alloy liner plate manufacture completes.It is worth explanation It is to use this temperature and cool time to be conducive to organizing the formation of of Dispersed precipitate carbide on single austenite, if the time The too low meeting of too short or holding temperature makes carbide increase, and will have a strong impact on the toughness of liner plate.
Because heat treatment process is not related to the change of component, so the as cast condition abrading-ball that obtains of step (a) and through Overheating Treatment After the component of the multicomponent alloy liner plate of step (b) that obtains be consistent.
