It ensures the uniformity of heating and quenching temperature, has small bending deformation after heat treatment, and can improve the product quality and yield.
Description
Technical field
The present invention relates to the ball mill technical field, specifically is the production method of the frotton that uses in the ball mill.
Background technology
Frotton is a kind of novel grinding-material, is the bigger novel lost material of serious wear, consumption that uses in the new ball mill in recent years.Use the new ball mill of frotton to be applied in the industries such as metallurgy, building materials, cement, mine at present.
At present, be that charge bar is just translation in conveying and heating process, does not rotate with the method for putting into the quenching-in water processing after the well-type electric furnace heating again in the frotton production process.After this method heat treatment, charge bar flexural deformation is big, and hardness is inhomogeneous; The hardness deviation of same frotton two ends or positive and negative diverse location is just very big.Because the material after the heat treatment has intensity and elasticity preferably, so use relatively difficulty of the heat treated frotton straightening of well-type electric furnace, need repeatedly several times even tens straightening repeatedly, even also be difficult to reach the quality standard that nonstraightness is equal to or less than 1/1000mm like this.Simultaneously, this heat treatment method labour intensity is big, production cost is also higher.
Summary of the invention
In order to overcome the shortcoming that above-mentioned prior art exists, the object of the present invention is to provide a kind of milling-rod production method, its guarantees the uniformity of heating and hardening heat, after the heat treatment flexural deformation little, can improve product quality and yield.
Technical scheme of the present invention is: this milling-rod production method may further comprise the steps:
The finished product round steel is pressed certain specification and length blanking;
The roller-way that utilization is made up of the roller of a plurality of equidirectional uniform rotation that are parallel to each other is carried good down charge bar, and the roller circumferential surface is provided with " V " connected in star; All rollers of this roller-way are obliquely installed in same horizontal plane, and charge bar places " V " connected in star of roller, and the axis of charge bar intersects with the axis of roller is non-perpendicular; When roller turn, roller to charge bar produce one along the mobile component of self axial advancement and one around the rotational component that self axis rotates, rotate around self axis when charge bar is advanced on roller-way;
Roller-way is transported in the box type heater heating continuously with charge bar, and charge bar rotates around self axis on roller-way and can make heating more even; After temperature reached 850～900 ℃, roller-way delivered into quenching unit with charge bar, handled by carry out spray quench to the charge bar water spray around charge bar;
Charge bar after the quenching is exported from quenching unit through roller-way, and after surface temperature was cooled off naturally and also reduced to normal temperature gradually, roller-way was sent into charge bar box tempering furnace again and carried out the evenly heating realization modifier treatment continuously second time; When temperature was heated to 250～300 ℃, roller-way was exported charge bar from box type heater, and cooling obtains frotton naturally;
Through check, when the frotton linearity can not meet the demands, with roller-way frotton is sent into again and carried out the straightening processing in the forcing press, until qualified.
As further technical scheme of the present invention:
In this milling-rod production method, the hardening heat of described charge bar is 850 ℃.
In this milling-rod production method, the bottom of " V " connected in star of described roller is an arc transition, and the outer circumference surface of circular arc and charge bar adapts.
The invention has the beneficial effects as follows: this method is a kind of high efficiency, low consumption, free of contamination frotton manufacturing technique method.Compare with existing production method, the quality of production of frotton is stable, and heat treatment hardness value excursion is little, and frotton nonstraightness deformation range is little, and labor strength is little, output is high.(for details see attached table one, subordinate list two)

The specific embodiment
As shown in Figure 1, this milling-rod production method may further comprise the steps:
The finished product round steel is pressed certain specification and length blanking.Good charge bar places on the discharging frame down, utilizes the roller-way of being made up of the roller 2 of a plurality of equidirectional uniform rotation that are parallel to each other to carry good down charge bar 1 then, and roller 2 circumferential surfaces are provided with " V " connected in star 3.The bottom of " V " connected in star 3 of roller is an arc transition, and the outer circumference surface of circular arc and charge bar 1 adapts.Realize rotating at the uniform velocity in the same way by chain and sprocket driving device 4 between the installation shaft 5 of each roller.Also can adopt other transmission devices to realize, be easy to realize as the those of ordinary skill in the present technique field.
