preparation example Construction

[0055] The present invention also provides a method for preparing an alloy material with an anti-fouling application, comprising the following steps:

[0056] Step 1. Select smelting raw materials:

[0057] The smelting raw materials are selected in the following two ways:

[0058] Method 1. Each component is smelted in pure metal form Cu-CATH-2, Zn99.99, Ni99.50, Sn99.99, Mn99.5, Al99.5, Au99.99;

[0059] Method 2. The high melting point component Mn is added in the form of master alloy CuMn22, and the rest is smelted with pure metal Cu-CATH-2, Ni99.50, Al99.5, Zn99.99, Sn99.99, Au99.99;

[0060] Step 2, ingredient calculation:

[0061] Calculate the mass of each element required in smelting by the mass percentage of the set alloy elements Cu, Zn, Ni, Sn, Al, Mn, Au, and use the mass of each element to calculate the intermediate alloy or pure alloy required in smelting metal content;

[0062] Step 3. Select the melting tool;

[0063] Step 4: Select a smelting process for...

Embodiment 1

[0077] In this example, the diameter The alloy test chip made of the alloy material of the present invention is put into the calcium carbonate solution with a flow rate of 1m / s and a concentration of 4900mg / mol, and the relationship between the current value and time is measured, as figure 1 As shown, it can be seen that the metal elements Au and Au added in the present invention are metal elements with the highest electrode potential, which can improve the free energy of reaction on the surface of the alloy, and have stronger descaling ability than similar products.

[0078] In this embodiment: the mass percentages of the components of the alloy material are: Cu=50%, Zn=25%, Ni=16%, Sn=2.45%, Al=3.5%, Mn=3%, Au=0.05% , the tested alloy with this composition has the best descaling ability.

[0079] Specific application cases:

[0080] Case 1. A heat exchanger in a chemical plant in China, because the circulating water contains a large amount of calcium and magnesium ions an...

Embodiment 2

[0125] In this example, the mass percentages of each component of the alloy material are: Cu=55%, Zn=23%, Ni=14%, Sn=2.47%, Al=2.5%, Mn=3%, Au=0.03% , batching calculation, smelting tool and smelting process are all similar to embodiment 1, no further elaboration will be given.

Abstract

The invention provides an alloy material with anti-fouling application, which comprises the following components in mass percentage: Cu: 45%-55%, Zn: 22%-35%, Ni: 11%-25%, Sn: 2 % to 4%, Al: 2% to 3.5%, Mn: 1.5% to 3.5%, Au: 0.01% to 0.1%. The invention also discloses a preparation method thereof, which includes selecting smelting raw materials, performing batch calculation, and selecting smelting tools and smelting processes for smelting. According to the invention, different metal element proportions are then alloyed to form alloy materials, so as to prevent fouling of equipment in the industrial production process, improve thermal efficiency of equipment, and reduce production costs.

Description

technical field [0001] The invention relates to alloy materials, in particular to an alloy material with anti-fouling application and a preparation method thereof. Background technique [0002] In the process of industrial production, water is often used as a carrier of heat transfer. It is inevitable that there will be serious scaling on the surface of related equipment. Scaling on the surface of equipment will increase thermal resistance, reduce thermal efficiency of equipment, and increase maintenance costs. Cause serious economic losses. According to statistics, the economic loss caused by equipment fouling in my country is about 0.3% of the total industrial production value. Equipment fouling may even cause explosions. Pipeline scaling will increase the flow resistance of pipeline fluid and increase resistance loss. , and a series of hazards. [0003] At present, the solution to this kind of scaling problem is mainly to add chemical agents, pickling or alkali washing, bu...
