The utility model overcomes current deflector roll life is short, and the roll change is frequent not enough, has long, high temperature resistant, the resistant high characteristics of strikeing of life.
Description
Technical field
The utility model relates to a kind of deflector roll of support guide steel band, specifically a kind of deflector roll of steekle mill equipment.
Background technology
Steekle mill, also known as Jill Sterkel milling train (Steckel milling train).The tentative steekle mill of First has been developed in 1932 and since being formally applied to industrial production in 1949, existing nearly 70 years history so far from the U.S..Over 70 years, steekle mill experienced by traditional, reworked, contemporary three developing stage.
The current situation and development of China's steekle mill: the company such as Shoudu Iron and Steel Co, Taiyuan Iron and Steel Co. has introduced 2030,1400,1,549 three second-hand steekle mill production lines respectively in the eighties; In Tenth Five-Year Plan Period, the steekle mill production line project of national planning Duo Jia steel mill is now all constructed and put into operation; The stainless steel steekle mill of the Article 1 totally-domestic of China's autonomous Design Self-Integration in 2008 builds up and goes into operation.Along with the application of the development of modern metallurgical technology and modern transmission, control technology, steekle mill has stepped into flourish period.
Steekle mill technical process has:
Before steel plate blank heating → high-pressure water descaling → steekle mill roughing → flying shear → finish rolling de-scaling → finish rolling → section cooling → bundling cut → check → pack warehouse-in.
In above-mentioned technological process, steel plate blank gauge 100 ~ 250mm, width dimensions 750 ~ 1650mm, length dimension 5000 ~ 12000mm, steel billet temperature is greater than 750 DEG C, and weight is maximum reaches 45 tons.Steel billet, by conveying roller transmission, enters steekle mill through inlet of rolling mill deflector roll and carries out reciprocating rolling, cooled by water under high pressure.In the operation of rolling, steel billet turnover steekle mill repeatedly guided by deflector roll, and working environment is high temperature, high humidity, HI high impact.Deflector roll is a critical component of steekle mill.Existing deflector roll product is solid monolithic deflector roll, and its service life is short in one month, and roll change is frequent, has a strong impact on manufacturing schedule, becomes a weak link in rolling process.Urgently according to onsite application operating mode, a kind of new product of development and Design solves this bottleneck problem.
Summary of the invention
Goal of the invention of the present utility model is short for service life in order to overcome existing deflector roll, and roll change is not enough frequently, has long service life, the feature of high temperature resistant, resistance to HI high impact.
The utility model solves the technical scheme that its technical problem adopts: two cover high temperature self-aligning roller bearings are set between roller shell and axle, is separated inside two cover high temperature self-aligning roller bearings by the shaft shoulder of spacer ring and axle; The axle sleeve being sleeved on axle two ends is pressed in outside high temperature self-aligning roller bearing inner ring; The end cap being loaded on roller shell two ends is pressed in outside the outer ring of high temperature self-aligning roller bearing, is set in outside axle sleeve, is provided with metallic packing ring between end cap and axle sleeve in the middle part of end cap; Axle both ends of the surface are respectively equipped with pressure release steam vent, air bleeding valve is equipped with in pressure release steam vent outer end, and pressure release steam vent is inner corresponding with high temperature self-aligning roller bearing.
Pressure release steam vent is inner corresponding with outside high temperature self-aligning roller bearing inner ring.
Axial end is also provided with the oil duct for lubricating high temperature self-aligning roller bearing.
Oil duct is inner corresponding with middle spacer ring.
End cap is fixed on roller shell through screw, packing ring.
Adjusting pad is provided with between end cap and roller shell.
When steel billet is by deflector roll, the impulsive force that steel billet produces is decomposed, and tangential decomposing force is converted into the rotary power of roller shell, and radial decomposing force is born radial load by high temperature self-aligning roller bearing, greatly reduce the impact failure degree of steel billet to deflector roll, improve the shock resistance of deflector roll.The beneficial effects of the utility model are: the shock resistance that improve deflector roll, improve the service life of deflector roll, reduce the number of times of roll change, save running cost.
Accompanying drawing explanation
The enforcement legend provided below in conjunction with accompanying drawing 1 is described in further detail the utility model.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In Fig. 1, two cover high temperature self-aligning roller bearings 6 are set between roller shell 7 and axle 1, and are separated by the shaft shoulder of spacer ring 5 with axle 1; Axle sleeve 2 is sleeved on axle 1 two ends and self-aligning roller bearing 6 inner ring compresses; End cap 8 is located at roller shell 7 two ends, compresses with the outer ring of high temperature self-aligning roller bearing 6, and is fixed on roller shell 7 by screw 9, packing ring 10; Axle sleeve 2 is corresponding with end cap 8.End cap 8 endoporus is provided with annular groove, and annular groove is embedded with metallic packing ring 3, and metallic packing ring 3 endoporus contacts with axle sleeve 2, seals, and prevents water under high pressure from entering deflector roll inside.The varied in thickness of adjusting pad 4 can control the crush of end cap 8 pairs of high temperature self-aligning roller bearing 6 outer rings; Center, axle 1 one end is provided with oil duct vertically, and oil duct leads to middle spacer ring 5 corresponding position, to high temperature self-aligning roller bearing 6 lubricate.Axle 1 two ends are provided with air bleeding valve 11-1,11-2, and air bleeding valve leads to the both sides of high temperature self-aligning roller bearing 6 via pressure release steam vent, when deflector roll is heated or when adding grease, regulate deflector roll air pressure inside balance by air bleeding valve pressure release.
