Abstract
The utility model discloses a kind of Continuous Casting Rolls water-cooling bearing blocks applied to metallurgical equipment field.The water-cooling bearing block forms layer of Ni-P amorphous structure alloy-layer in bearing block surface of shell and internal water channel surface.10-30 μm of alloy layer thickness of the Ni-P amorphous structure, finish are not less than ▽ 8-10, hardness 600-1100HV, bond strength >=400MPa with matrix.With good corrosion resistance, high temperature resistant, wearability, have the characteristics that heat reflection is obviously and less scaling simultaneously, corrosion-resistant, heat-blocking action is improved to play, keep cooling water circulation smooth, improve the service life of water-cooling bearing block, uncap clearing times and the maintenance cost for reducing bearing block, reduce the maintenance workload of Continuous Casting Rolls.
Description
Technical field
The utility model is applied to metallurgical equipment field, the in particular to water-cooling bearing block of Continuous Casting Rolls.
Background technique
Metallurgy industry is very universal using water-cooling bearing block on the Continuous Casting Rolls of conticaster, and water-cooling bearing block has become company
The important component of casting roll, under normal circumstances, water-cooling bearing block are welded by straight carbon steel main body and stainless steel cover board group, due to
Its work is under the hyperthermia radiation of red heat continuous casting billet and the washing away of spraying cooling water, seriously corroded.When water-cooling bearing block works,
Its internal cooling water channel leads to cooling water.For the north, water quality is harder, and cooling water channel is thinner, easily formation different shape,
The scale crust of property and thickness causes the increase of maintenance workload, uses the longevity frequent occurrence the phenomenon that scale blocking cooling water channel
Life is shorter, especially directly influences bearing life and Continuous Casting Rolls safe operation, and to conticaster, continuously reliably operating brings hidden danger.
Summary of the invention
The technical issues of the utility model is solved is: providing a kind of Continuous Casting Rolls water-cooling bearing block, prevents cooling water channel from producing
It scales, improves bearing block service life.
The technical scheme adopted by the utility model is
Layer of Ni-P amorphous structure alloy is formed on bearing block housing outer surface, top cover outer surface and inner lead surface
Layer.10-30 μm of alloy layer thickness of the Ni-P amorphous structure, finish are not less than ▽ 8-10, hardness 600-1100HV, with
Bond strength >=400MPa of matrix.
The beneficial effect that the utility model obtains is: the Ni-P amorphous structure alloy-layer improves corrosion resistance, may be used also
Heat-blocking action is played, keeps cooling water circulation smooth, improves the service life of water-cooling bearing block on the whole, reduce bearing block
Clearing times of uncapping and maintenance cost reduce the maintenance workload of Continuous Casting Rolls.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Wherein: 1- bearing block housing outer surface, 2- top cover outer surface, 3- inner lead.
Specific embodiment
The utility model embodiment is as shown in Fig. 1, carries out finishing to the inner wall of bearing block outer profile and inner lead 3 first
Work, roughness about Ra1.6, then finished product whole implementation surface alloy catalyzing, stainless in water-cooling bearing block housing outer surface 1,304
Steel top cover outer surface 2 and 3 surface of inner lead form compact Ni-P amorphous structure alloy-layer.
The Ni-P amorphous structure alloy-layer has good corrosion resistance, with a thickness of 10-30 μm, hardness about 600-
1100HV, about 860-880 DEG C of fusing point, bond strength >=400MPa with matrix, alloyed layer finish is not less than ▽ 8-10,
Reflection coefficient 50% or so, so the alloy-layer has high temperature resistant, resistance to erosion, wear-resisting feature, while have coefficient of friction it is low,
The obvious and less scaling feature of heat reflection.
Compared with traditional Continuous Casting Rolls water-cooling bearing block, the utility model advantage is as follows:
1, the Ni-P amorphous structure alloy-layer on 3 surface of inner lead, smooth non-scaling, so that inner lead coefficient of friction is significant
It reduces, protrusion non-stick, smooth in water flow, good heat dissipation.The Ni-P amorphous structure alloy-layer good corrosion resistance, so that inner lead is resistance to
Corruption improves 10 times or more.
2, the Ni-P amorphous structure alloy-layer of the stainless steel top of water-cooling bearing block housing outer surface 1 and 304 exterior surface 2,
The heat radiation for playing good barrier high temperature red heat continuous casting billet, a possibility that further decreasing bearing block hot operation.The alloy-layer
Good corrosion resistance, so that bearing block corrosion fatigue life under harsh operating condition increases.
Although 3, Ni-P amorphous structure alloy-layer thickness is thin, its hardness is high, and wearability is good, can tolerate miscellaneous in cooling water
The high speed of matter is washed away, long service life.
In short, the Ni-P amorphous structure alloy-layer one can play heat-blocking action, two can make water flow unobstructed, play fast cold-working
With three improve corrosion resistance, to improve 10 times of service life or more of water-cooling bearing block on the whole, greatly reduce bearing
Uncap cleaning workload and the maintenance cost of seat.
