The present invention generally relates to nickel alloy pluramelt and production method thereof, and is particularly a kind of with cheap steel plate, as mild steel plate or carbon steel sheet, is soldered to a kind of nickel alloy pluramelt of producing on the expensive good acidproof corrosion-resistant nickel-base alloy plate.
Known as one's own profession personage institute, pluramelt generally is welded the different metal plate by this way, is about to cheap parent metal, has good acidproof corrosion resistant expensive metal plate as mild steel or the bottoming of carbon steel stratification and the one deck of burn-oning.This clad metal has advantages of being cheap, and has good being expected from the mechanical performance of conventional steel plate acquisition, also has good being expected from the acidproof corrosion resistance of particulate metal acquisition of costliness.Therefore, this cladding sheet is widely used for various uses, as distillation system, and freshwater system and power plant desulfurization system, the acidproof and corrosion resistance that these system requirements are good.
In the steam generator system of power plant, when using heavy oil or coal to do fuel combustion, produce a large amount of sulphur dioxides, cause environmental pollution.Therefore, the desulphurization system of collecting and removing sulphur dioxide must be installed.But in such steam generator system, the absorption tower of desulphurization system, conduit and chimney etc. are corrosion easily, because they always are exposed in the sulphur dioxide.Thereby, the lost of life of desulphurization system, force the owner with too much expense with new replacement existing systems.
In order to address the above problem, the method for this purposes steel plate of several manufacturings has been proposed.At first, have good acidproof corrosion resistant single metal plate and can be used for being exposed to part in the sulphur dioxide.The second, with a cheap steel plate with have cladding sheet that good acidproof corrosion resistant metallic plate combines and can be used for being exposed to part in the sulphur dioxide.Yet the problem that first method has is and since be expensive metal it is very expensive, and this plate is installed very difficult in system like this.For this consideration, use the cladding sheet of producing according to second method more desirable at present.
Introduce the technology of making cladding sheet according to prior art below.This cladding sheet can be by several method production.At first, cladding sheet can be produced by the explosive welding (EW) connection, and this is to utilize the force of explosion of explosive that the erosion-resisting metallic plate of height is welded on the plain steel plate.In addition, cladding sheet can be produced by the roll bonding method, and this is by means of a thermo roll anticorrosive plate and plain steel to be hardened to close.As another kind of method again, cladding sheet can be by the production of seam resistance welding method, and this is to use a kind of bond, as stainless (steel) wire, copper mesh or sheet copper in conjunction with noncorroding metal plate and plain steel plate.Though the quality of the cladding sheet of being produced by first and second kind method is good, they be costliness and also the machined difficulty, and machinability is poor.And therefore first and second kind method waste material hinders and uses them.Simultaneously, it is cheap that the seam resistance welding method is compared with other method, makes it preferentially be widely used for producing pluramelt.
But the seam resistance welding method has a bond problem, and as stainless (steel) wire, copper mesh or sheet copper can not harden corrosion resisting alloy effectively and be incorporated on the steel plate.Thereby the cladding sheet that this method is produced as low lamentedly on tensile strength, tearing strength and the shear strength, therefore can not satisfy user's requirement in mechanical performance.
Chinese invention patent communique CN1151354 discloses a kind of lining material, it comprises (iron system) substrate metal layer, corrosion-resistant metal sheet material and places the nickel between this substrate metal layer and the corrosion resistant metal sheet material is metal level (nickel foil), by the weld seam welding this three is mutually combined.This lining material has mechanical performance and good acidproof and corrosivity preferably.As everyone knows, nickel is a kind of rare precious metal.This invention covers nickel plate or net on the whole surface of base material steel plate, has increased manufacturing cost inevitably yet regrettably.
Therefore, in order to solve the problems referred to above that occur in the prior art, the purpose of this invention is to provide a kind of method of making the nickel-base alloy cladding sheet, this method can reduce the consumption of precious metal (nickel) effectively, and makes the weight saving of final products.
Another object of the present invention provides the nickel-base alloy cladding sheet that a kind of use precious metal (nickel) is less and weight is lighter.
In order to achieve the above object, the invention provides a kind of method of making the nickel alloy cladding sheet, the step of this method comprises: earlier a plurality of thin nickel straps or stainless steel band are attached on the steel plate along the predetermined operation line that stitches electric resistance welding; By the seam electric resistance welding nickel-base alloy plate is welded on the described steel plate, described a plurality of thin nickel straps or stainless steel band are inserted in and are welded between described two plates.
And, the invention provides a kind of nickel alloy cladding sheet, this plate comprises: a steel plate and a nickel-base alloy plate that is welded on the described steel plate, between described two plates, insert a bond spare, it is characterized in that described bond spare comprises a plurality of thin nickel strap or the stainless steel band that only is arranged on the seam electric resistance welding welding production line.
The present invention only attaches to many nickel straps on the steel plate along the predetermined operation line of seam electric resistance welding, rather than nickel plate or net are covered on the whole surface of base material steel plate.Thereby saved the consumption of precious metal nickel greatly, and making the weight saving of final products (cladding sheet) simultaneously, cost reduces.
Above-mentioned purpose of the present invention and further feature and advantage are from more clear below in conjunction with meeting the description of the drawings.In the accompanying drawing:
Fig. 1 is the enlarged perspective of nickel alloy cladding sheet according to a preferred embodiment of the invention.
According to the present invention, a thin bond plate, as a thin nickel plate, thin stainless steel base plate, nickel strap or stainless steel band at first attach on the steel plate.Then, by seam electric resistance welding method one nickel-base alloy plate is welded on this steel plate, this bond is inserted between nickel alloy plate and the steel plate.
The following describes the combination of steel plate and nickel alloy plate.At first, big electric current flows through between steel matrix plate and nickel alloy plate, thereby at once high resistance heat takes place.Therefore bond is melted by high resistance heat.Nickel-base alloy plate and steel plate fusion when bond melts, thus steel plate and nickel alloy plate are firmly welded.
Preferably a kind of flux is added to bond two, so that the nickel alloy plate is melted on the steel plate effectively.
Be because of its cheapness as the matrix steel plate and have the intensity that hope is wanted with carbon steel sheet.
