Abstract
The invention discloses a machining method for a high-hardness and high-tenacity 65 Mn steel rod of a rod mill. Molten steel comprises, by weight, 0.62%-0.70% of C, 0.17%-0.37% of Si, 0.90%-1.20% of Mn, smaller than or equal to 0.035% of S, smaller than or equal to 0.035% of P and the balance Fe. According to specific technological parameters, an intermediate frequency furnace is selected for smelting, when the temperature of 1,650-1,720 DEG C is reached due to smelting, a deoxygenation agent accounting for 0.4%-0.5% of the weight of the molten steel is added for deoxygenation, then power is off, the molten steel is discharged out of the furnace, and casting molding is carried out with the temperature of 1,560 DEG C-1,600 DEG C. According to the machining method for the high-hardness and high-tenacity 65 Mn steel rod of the rod mill, by means of adjustment on the technological parameters and more precious treatment, the obtained 65 Mn steel rod is higher in abrasion resistance and tenacity, and then the service life of the steel rod is prolonged.
Description
Technical field
The present invention relates to the working method of a kind of high rigidity for rod mill, high tenacity 65Mn rod iron.
Background technology
Along with the fast development of China's industry, all trades and professions are had higher requirement to energy-saving and cost-reducing.The raising production efficiency of production unit and the work-ing life of extension device are energy-saving and cost-reducing effective means.Heat treatment industry also at the potential of constantly employing new technology, novel process fully excavates material, extends its work-ing life, to reach energy-saving and cost-reducing object.
As a kind of conventional mine size reduction machinery, rod mill there has also been significant progress in recent years.Grinding medium-the frotton (rod iron) of the type machinery is the running stores of rod mill, and existing commercially conventional abrasion-proof manganese steel rod is primarily of steel mill's roll forming, and its mechanical property is not high, and abrasion resistant effect extreme difference, consumption is very big in use.The production cost that traditional rod iron produces due to abrasion is high, can not meet the growth requirement of industry, and the wear-resisting rod iron of development of new is imperative.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides the working method of a kind of high rigidity for rod mill, high tenacity 65Mn rod iron.
Object of the present invention carrys out specific implementation by the following technical programs:
For the high rigidity of rod mill, a working method for high tenacity 65Mn rod iron, select the chemical composition of molten steel, by weight percentage meter: C%:0.62 ~ 0.70, Si%:0.17 ~ 0.37, Mn%:0.90 ~ 1.20, S% :≤0.035, P% :≤0.035, all the other are Fe, concrete technology parameter is: select intermediate frequency furnace melting, when melting is to 1650-1720 DEG C, adds 0.4% ~ 0.5% reductor deoxidation of Metal Weight, have a power failure afterwards and come out of the stove, with 1560 DEG C-1600 DEG C temperature cast moldings.
Beneficial effect of the present invention:
The working method of the high rigidity for rod mill provided by the invention, high tenacity 65Mn rod iron, by the adjustment to processing parameter, processes more accurately, and the wear resisting property of the 65Mn rod iron obtained is higher, and toughness is stronger, and then extends the work-ing life of rod iron.
Embodiment
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
embodiment 1:
For the high rigidity of rod mill, a working method for high tenacity 65Mn rod iron, select the chemical composition of molten steel, by weight percentage meter: C%:0.62 ~ 0.70, Si%:0.17 ~ 0.37, Mn%:0.90 ~ 1.20, S% :≤0.035, P% :≤0.035, all the other are Fe, concrete technology parameter is: select intermediate frequency furnace melting, when melting is to 1650-1720 DEG C, adds 0.4% ~ 0.5% reductor deoxidation of Metal Weight, have a power failure afterwards and come out of the stove, with 1560 DEG C-1600 DEG C temperature cast moldings.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
