Abstract
The special equipment of waste heat burning optimization on line after a kind of abrasive media hot rolling, belongs to burning optimization on line technical field after metal product hot-roll forming.It is on hot rolling abrasive media production line, special waste heat press quenching equipment is configured according to two-stage slack quenching refrigeration standard, to carrying out being shunted to the high cooling earthquake intensity quenching of level-one after the hot abrasive media precooling of roll forming, through of short duration air-cooled tempering soaking, it is tempered surface layer martensite, center portion then continues to cool down, and reduces center portion and the temperature difference on surface, again to the low cooling earthquake intensity slow cooling of two level to temperature of quenching eventually, finally heat preservation self tempering is carried out using abrasive media waste heat or other methods are tempered.The utility model can effectively reduce abrasive media hardening break tendency, improve quenching quality, and heat treatment hardness is increased to 60~68HRC.
Description
Technical field
The utility model is related to the waste heat burning optimization on line equipment after a kind of metal product hot-roll forming, more particularly to one
Continuous online immediate quenching heat treatment special equipment, is particularly suitable in ball mill abrasive media after kind abrasive media hot rolling
Steel ball.
Background technology
Before more than 30 years, the 4th steel rolling subsidiary factory of Hebei Handan steel enterprise company, which initiates, has succeeded in developing abrasive media ball-mill steel
Ball, steel section roll rear waste heat burning optimization on line technique and the equipment patent No.：CN85 104240, process characteristic are：Full utilization is ground
Waste heat after grinding media roll forming, pre-cooled-quenching-residual heat insulation self tempering, make the 65Mn used then, Properties of Heavy Rail Steel and
The medium high carbons manganese steel abrasive media case hardness such as 45Mn2 has reached the advanced international level of 52~60HRC.But this kind of medium high carbon manganese
The quenching degree of steel steel grade is poor, and abrasive media surface layer layer thickness of hardening only has 8~12mm, and abrasive media inner hardness only has 35~
48HRC, although abrasive media toughness is preferable, non-breakable, overall wear resistance is unsatisfactory.
Between the eighties in last century to 2000, the abrasive media of Handan Iron and Steel Co research and development rolls rear waste heat burning optimization on line technique and sets
Standby, structure feature is there are mainly three types of various form and configuration, first, double chain bucket elevator abrasive media Pre-cooling equipment, double
Row chain scraper-type quenching press abrasive media quenching apparatus；Second is that the spiral discharge abrasive media equipped with useless ball screening device is pre-
Rotating disc type abrasive media splitter, double-screw type of the both sides with baffle that cool equipment, sprocket wheel and worm-gear speed reducer drive are ground
Grinding media quenching press；Third, the side that double chain bucket elevator, adjustable speed motor drive is without baffle-type rotating disc type splitter, double
Spiral abrasive media quenching press.
In these Equipments for Heating Processing, splitter and quenching press have the following disadvantages：
First, spiral quenching press is the conveyor screw of a whole uniform pitch, and when abrasive media quenches, speed of advancing from the beginning to the end
Degree is the same, and cooling condition is the same, and cooling medium is constant, particularly when martensite transfor mation occurs, it is impossible to reduce cooling velocity, hold
Easily abrasive media is caused to crack, the more fine techniques requirement of abrasive media heat treatment process is not achieved.Double strand chain scraper-type quenches
Machine there is also it is such the problem of.
Second is that spiral quenching press latter end, abrasive media cannot be completely immersed in quenching medium, cause on abrasive media
Portion exposes in air, and lower part is still quickly cooled down in medium is cooled down, and abrasive media local excessive is caused to cool down.
Third, the rotating disc type splitter that spiral quenching press sprocket wheel-worm-gear speed reducer drives, it can only be abrasive media point
Go out for one side, before go out ball two-way always, two-way ball mouth height difference up to more than 300mm causes abrasive media to enter two
It is very uneven in spiral quenching press, per lattice spiral impeller in there is double balls, three balls, the situation in space often beyond 20%, seriously
Influence abrasive media quenching quality and efficiency.
Due to matter such as the steel grade of the mainly medium high carbon manganese steel series of hot rolling abrasive media use then, abrasive media hardness
Amount requirement is not also high, therefore, to abrasive media heat treatment process then and the technological parameter of Equipment for Heating Processing, device parameter with
And the requirement of Operational Control Level is also more tolerant, largely masks above-mentioned abrasive media heat treatment process and equipment exists
Deficiency and drawback in design.
In the latest 20 years, with the development of domestic and international broken ore grinding technology and equipment, all types of user is to abrasive media product
Quality proposes higher requirement, and universal quality requirement is：Hardness is 58~63HRC or even 62~66HRC or higher；It grinds
It hardens completely inside and outside grinding media and hardness is required to be evenly distributed, difference of hardness is less than 3HRC；Hardness gradient is reasonably distributed, good toughness,
Ballistic work will reach 12J/cm2Or higher, the requirement of falling sphere experiment number reach 12000 times or more, ensure abrasive media not fragmentation.
The raising of abrasive media product quality requirement promotes new grinding medium to come into being, domestic various forgings and rolling
Abrasive media generally employ various medium high carbon low-chromium multi-element antifriction alloy steel grades.Main chemical compositions are：Carbon 0.5~
1.0%, chromium 0.5~4.5%, the resistance to break-in of multielements such as suitable manganese, silicon and a small amount of, micro vanadium, titanium, nickel, tungsten, molybdenum, copper
Golden steel grade.The heat treatment process of the abrasive media of these miscellaneous wear resistance alloyed materials is different, but nearly 20
Nian Lai, domestic each factory, which still continues to use or copy the abrasive media that Handan Iron and Steel Co was invented before 30 years, rolls rear waste heat burning optimization on line and sets
Standby, quenching effect is undesirable, and hardness is uneven, and cracking, poor toughness, efficiency are low.Therefore, for new steel grade and different grinding mediums
Matter production line, of new generation abrasive media waste heat burning optimization on line technique and equipment of the research and development with extensive practicability are imperative.
