Description
Technical field
The utility model belongs to wire production technical field, be related to a kind of wear-resistant material deflector roll for rolling high line and its
Mating guide and guards.
Background technique
High-speed rod-rolling mill rolls speed to 140 m/s, leads high line raw using the 45 ° of high speed wire rod finishing blocks of root that rub as representative
The revolutionary variation in production field.With the raising of mill milling speed, the quality of rolling guide decides production success or failure.Deflector roll
Be the main consumable part on high-speed rod-rolling mill, bear the effect of high link friction in work, percussion and high temperature wire rod plus
The Quench of heat and cooling water, therefore deflector roll is required to have high rigidity, high tenacity, high thermal fatigue resistance and anti-stick rigidity.But it is general at present
Lower all over the cast steel with high chromium, hot die steel (first generation) deflector roll red hardness used, service life is short, influences high line production efficiency
And product qualification rate.Common austenitic heat-resistance steel, martensite wear resistant steel or wear resistant cast iron deflector roll, service life is all short, cause
Operating rate of rolling mill reduces.
The hard alloy deflector roll and composite guide roller of developmental research have good wearability and high-temperature stability, still, because
It is obtained in production for the influence such as pass machining, steel rolling site environment, cooling water condition and machining condition using being restricted
Less than popularization.
The effect of deflector roll is that rolled piece is correctly imported milling train, and the hole type design of deflector roll is unreasonable to will cause rolled piece guidance not
It is suitable, cause piling of steel accident to occur, causes deflector roll to fail indirectly；In production, the requirement to material molded dimension is very strict, meets
It is required that workpiece measurement can make deflector roll fray within the scope of normal wear, once workpiece measurement is undesirable, can not only add
The failure of fast deflector roll can more likely generate piling of steel, cause production accident.
When the hole type design of deflector roll is too small or workpiece measurement is bigger than normal, when rolled piece passes through guide and guard, deflector roll can be squeezed, makes to lead
It defends support arm to be softened, deflector roll clamping force increases, and deflector roll excessive wear is caused, so as to cause deflector roll failure；When the pass of deflector roll
Design excessive or workpiece measurement it is less than normal when, deflector roll be difficult clamp rolled piece, so that rolled piece is generated shake between rack, fall
Steel, rolled piece wear deflector roll both sides along deflector roll diagonal positions, and reduce deflector roll uses the time, to reduce rolling guide
Service life.
Rolling guide is chiefly used in guidance elliptical rolled piece, and into people's circle or square groove etc., deformation is unstable, tandem rolling speed is higher
Unit, it is ensured that obtain the rolled piece that geometry is good, dimensional accuracy is high.High-speed wire rolling passage is more, speed is fast, guide and guard
The adjustment and replacement of device are frequent.Various problems existing for rolling guide system in the prior art, such as structure is complicated, assembly is tired
It is difficult；It is not easy to adjust in production and replace；Seriously restrict the raising of productivity.
Therefore, a kind of abrasion resistance material deflector roll and its mating guide and guards are needed, is closed containing a large amount of W, Mo, Cr, V etc.
The deflector roll of gold element has very high room temperature hardness, high temperature abrasion resistance and excellent red hardness, while passing through deflector roll size design
It is helped so that deflector roll and rolled piece keep stablizing, guarantees that rolled piece can smoothly enter into deflector roll pass, while making deflector roll fray normal
In wear range, extend the service life of deflector roll；The design of guide and guards matched with wear-resistant material deflector roll should be according to pass system
System and configuration of the pass on roll, determine reasonable guide and guards structure and outer dimension, keep its installation, disassembly easy, position
It is accurate to set, fixed, guarantees that rolled piece steadily deforms in pass.Solve deflector roll be on active service when occur serious wear,
The problem of crackle and fracture failure, while meeting the needs of hardness, the composite request of toughness and full production.
Summary of the invention
In order to achieve the above object, the utility model provides a kind of wear-resistant material deflector roll for rolling high line and its mating
Guide and guards, it is low to solve deflector roll red hardness existing in the prior art, wears no resistance and service life is short and mating guide and guard
Apparatus structure is complicated, assembly difficulty, is not easy the problem of adjusting and replacing.
The utility model the technical scheme adopted is that provide it is a kind of for rolling the wear-resistant material deflector roll of high line, first
