Commonly used is price ZG40Cr28Ni48Si2 alloy costly, and roll shaft 1 is thick-walled seamless steel pipes.Roller
2 are arranged on roll shaft with flat key one, flat key two, in the welding of roll shaft end face with roller 2 with the block 5 of material, prevent
Roller comes off from roll shaft.Cooling water is delivered to roll shaft 1 front end by water inlet pipe 6, then in the hollow cavity of roll shaft 1
Return, complete the cooling of roll shaft 1.
During production practices, heating furnace often can carry out heating up according to organization of production, the change of technological requirement,
The operation of cooling, heating and cooling amplitude sometimes is the biggest, and normal use of hanging arm roll is brought adverse effect, often
Occur roller 2 ftracture, roll shaft 1 end face snaps and leaks, block 5 snap come off, roller 2 at roll shaft 1 play also
Eventually fall out the fault dropping in stove.
After hanging arm roll breaks down, can only roll off the production line by integral replacing, if repairing according to original design requirement, again
Equipped alloy roller, maintenance cost is higher, little with newly doing cost difference, often set more than 30,000, typically to old roller-way
Carry out scrapping process.So, the Year's consumption of steel rolling line upper cantilever roller-way is higher.
For above-mentioned deficiency, need hanging arm roll is made the most reasonably to design, reduce fault, extend and make online
With the life-span, reduce consumption.
Summary of the invention
It is an object of the invention to, it is provided that a kind of welding type water-cooled hanging arm roll for billet heating furnace, again set
