Description
Technical field
This utility model relates to a kind of quenching tank replacing heat treatment abrading-ball for water-cooled air cooling, belongs to Ferrous Metallurgy technology
Field.
Background technology
Along with the quickening of modernization industrial process, ball mill semi-autogenous mill diameter is increasing, and tradition minor diameter abrading-ball is one
Determining can not meet in degree industrial requirement, required abrading-ball size increases, and production efficiency improves in addition, and equipment operation speed is accelerated,
Friction aggravation between abrading-ball and liner plate.The traditional production technology of domestic bainite-martensite complex phase abrading-ball uses salt bath etc. completely
Temperature quenching, this traditional mode of production pattern energy consumption is big, and complex process, operation is long, and hardening media easily pollutes environment, thus causes production
The shortcomings such as cost is high, and quality is unstable.On this basis, scientific research personnel proposes one and utilizes water-cooled repeatedly, air cooling this
Novel Technology for Heating Processing, it is achieved the transformation of bainite and martensite.But in quenching process, rate of cooling is uneven to be easily caused
Quench structure property skewness that is uneven and that cause, thus in use easily cause cracking and even scrap.Cause
The uneven reason of rate of cooling mainly has 2 points: one is owing to workpiece austenitizing temperature is higher, after entering in hardening media,
The temperature of hardening media is affected relatively big, even if using the contact portion temperature of cooling recirculation system, hardening media and high temperature workpiece
Degree rises rapidly, and medium convection velocity is limited, it is impossible to lowers the temperature in time and causes rate of cooling to decline；Two is in the scorching hot work of high temperature
When part enters cooling medium, workpiece circumferential surface liquid is rapidly reached boiling point and vaporizes, and forms one layer of steam blanket, reduces heat and passes
Leading, slow down workpiece rate of cooling, affects the tissue after workpiece quenching and performance.
Summary of the invention
The technical problems to be solved in the utility model is to use water-cooled-air cooling repeatedly to replace the life of this novel thermal process technique
During producing major diameter abrading-ball, the uneven structure property skewness causing quenching uneven and to cause of rate of cooling.
The purpose of this utility model is to provide a kind of quenching tank replacing heat treatment abrading-ball for water-cooled air cooling, described in quench
Fire groove includes that outer case 1, internal box 2, water inlet pipe 3, negative pressure discharging device 4, ultrasonic generator 5, PLC control device 6, quenches
The bottom of fire groove is provided with multiple equally distributed ultrasonic generator 5, between outer case 1 and internal box 2；Ultrasound wave
Being provided with multiple equally distributed water inlet pipe 3 between generating means 5, water inlet pipe 3 is through outer case 1 and internal box 2 and internal box 2
Connection；Negative pressure discharging device 4 is positioned on the upper end sidewall of quenching tank, and negative pressure discharging device 4 is by cooling tower 7 with water inlet pipe 3 even
Logical, it is achieved recycling of cooling water；Ultrasonic generator 5 controls device 6 with PLC and is connected, it is achieved ultrasonic generator 5
Starting in Cooling Process, air cooling is closed during rising again.
The beneficial effects of the utility model: device described in the utility model utilizes porous inlet pipeline and high-power negative pressure to go out
The cooling medium circulation system of water lines composition, can effectively keep the constant of hardening media temperature, it is ensured that workpiece is at Cooling Process
In stablize heat exchange, make major diameter abrading-ball uniformly cool down in Cooling Process, reach uniform formation, improve workpiece hardness, intensity and
Wearability.Utilize ultrasonic generator can effectively eliminate the vaporization film of surface of the work in quenching process, make workpiece in water-cooled mistake
In journey, rate of cooling is unaffected.This device is utilized to pass through repeatedly the big straight of this novel thermal process technique of water-cooled-air cooling production
Footpath abrading-ball, its volume hardness is more than 50HRC, and impact flexibility is more than 10J/cm2, show the wear resistance of excellence.
