Abstract
The present invention discloses a high-intensity abrasion resistant electric arc spraying wire material for circulating fluidized bed boilers, which takes a low-carbon steel band or a stainless steel band as a wire material housing, and the mixture powder of CrB2 and B4 C is added into a wire core. The content of the mixture of CrB2 and B4 C is from 25 to 48 Wt percent, and CrB2 takes up 70 to 95 Wt percent of the mixture of CrB2 and B4 C. The thickness of the low-carbon steel band or the stainless steel band is from 0.3 to 0.5mm, and the wire core of the wire material contains 0 to 5 Wt% of one kind of the powders, such as Ni, Al, Mo and/or a rare-earth element. The electric arc spraying wire material of the present invention, which is applied to heating surfaces of circulating fluidized bed boilers, has a good abrasion resisting effect and has the service life 2 to 3 times longer than that of a coating layer made of a general abrasion resistant wire material in markets. The present invention can extend the service life of the heating surfaces of the circulating fluidized bed boilers by more than 3 to 10 times. The present invention can stilled be used for continuously making abrasion resistant coating layers on an original residual coating layer after adopting appropriate surface treatment, and accordingly, the present invention has the advantage of long service life.
Description
Technical field
The present invention relates to a kind of circular fluid bed arc spraying filament material, relate in particular to a kind of circular fluid bed high intensity abrasion resistant arc spraying filament material.
Background technology
Circular fluid bed is that China recent years is advocated and the type of furnace with fastest developing speed energetically because of three big characteristics such as clean, efficient and coal-fired wide adaptability enjoy favor.But because of warm circulating combustion wherein and a large amount of low grade coals of burning, heating surface exists extremely serious erosive wear, abrasive wear and eddy current wearing and tearing, and its degree of wear is much more serious than common coal-powder boiler.Most of circular fluid bed local heating face just occurred wearing and tearing booster problem in 1-3 month in operation, and it is shorter that the circular fluid bed heating surface that has grinds the quick-fried life-span, can safe operation half a year above circular fluid bed rarely found.
In order to solve circular fluid bed heating surface wear problem, people have done multiple trial, but from a large amount of practices, High Speed Electric Arc Spraying technology is the effective technology that the most suitable present on-the-spot big area solves its heating surface abrasionproof.Yet existing in the market arc spraying filament material all is difficult to reach the requirement of circular fluid bed heating surface abrasionproof, and the coating macrogamy is bad, and work-ing life is extremely short.The coating that the silk material that has is made is hard and crisp, hard is poor with matching property of adhesion, be easy to be washed away, though the coating toughness that the silk material that has is made is good, but too soft, not wear-resisting, the silk material that also has is difficult to meet the electric arc spraying process requirement, melt bad, easily current interruption and coating is inhomogeneous, unfairness or the like.Therefore, be necessary very much to develop the High Speed Electric Arc Spraying silk material of a kind of suitable circular fluid bed operation and wearing and tearing characteristics,, improve the abrasionproof effect to satisfy its abrasionproof requirement.
Summary of the invention
The objective of the invention is to: overcome the above-mentioned defective of prior art, a kind of circular fluid bed high intensity abrasion resistant arc spraying filament material of abrasionproof better effects if is provided.
The present invention realizes by following scheme: with mild-carbon steel strip or Stainless Steel Band is a material crust, is added with CrB in the silk core

4The mix powder of C.
CrB of the present invention
2And B
4The content of C mixture is: 25-48Wt%.
CrB of the present invention
2And B
