Problems solved by technology

However, when the silver-copper content is greater than or equal to 99.93%, and the silver content is between 0.088-0.195%, it is difficult to control the conductivity of the silver-containing copper bar at 1.765-1.898υΩ.cm (20°C); resulting in a large deviation in the conductivity of the silver-containing copper bar , can not meet the needs of the rotor winding of the condenser

Embodiment 1

[0034] A method for preparing a silver-containing copper rod for a large-capacity condenser, the steps are as follows:

[0035] Step 1, material preparation: take silver, iron and copper respectively; Impurities, so the sum of the weight percentages of the material components will not be as high as 100%, and the rest are impurities.

[0036] Step 2: Prepare the upward continuous casting unit: the upward continuous casting unit includes a power frequency melting furnace, a traction system, and a melt cooling crystallization system.

[0037] Step 3. Parameter adjustment: adjust the cooling water volume of the melt cooling and crystallization system, so that the water pressure in the melt cooling and crystallization system is kept at 0.26Mpa, and the temperature is kept at 26°C; the traction system includes guide rods, and the pitch of guide rods is 5.5mm .

[0038] Step 4. Power frequency melting furnace: There is molten copper water in the power frequency melting furnace, and...

Embodiment 2

[0041] The difference between this embodiment and Embodiment 1 is that the preparation method of a silver-containing copper rod for a large-capacity condenser uses the following steps:

[0042]Step 1. Material preparation: take silver, iron and copper respectively; and the weight percentages of the material components are: silver 0.1%, iron 0.001-0.005%, and the total content of copper and silver is equal to 99.975%. Because all contain impurity in general copper, silver, so the summation of weight percentage of material composition can not be up to 100%, all the other are impurity.

[0043] Step 2: Prepare the upward continuous casting unit: the upward continuous casting unit includes a power frequency melting furnace, a traction system, and a melt cooling crystallization system.

[0044] Step 3. Parameter adjustment: adjust the cooling water volume of the melt cooling and crystallization system, so that the water pressure in the melt cooling and crystallization system is kep...

Abstract

The invention relates to the field of metal machining, in particular to a method for preparing a silver-contained copper rod for a large-capacity phase modifier. The method comprises the following steps that of 1, material preparation; 2, upcasting continuous casting unit preparation; 3, parameter adjustment; 4, power frequency melting furnace using; and 5, rod guiding. The silver-contained copperrod manufactured through the scheme is adopted as a base material for manufacturing a silver-contained copper bar product, the conductivity deviation of the obtained silver-contained copper bar product is small, and the use need of a rotor winding of the phase modifier can be met.

Description

technical field [0001] The invention relates to the field of nonferrous metal processing, in particular to a method for preparing a silver-containing copper rod for a large-capacity condenser. Background technique [0002] The synchronous condenser, also known as the synchronous compensation machine, is used to improve the power factor of the grid and maintain the voltage level of the grid. Synchronous condenser is a kind of synchronous motor in a special operating state. When applied to the power system, it can automatically increase reactive power output when the grid voltage drops and absorb reactive power when the grid voltage rises according to the needs of the system, so as to Maintain voltage, improve the stability of the power system, and improve the quality of system power supply. It provides a brand-new solution for realizing long-term and stable power supply from power station to power grid in my country and even the world. [0003] The production process of the...
