Embodiment Construction

[0019] Specific embodiments of the present invention are introduced below.

[0020] First, the preparation method of the current-collecting sliding material is introduced:

[0021] Step 1. Dissolve high-quality copper in an electric furnace. Generally, copper with a purity greater than 99.9% is called high-quality copper. Put the broken copper pieces into the electrical furnace for stirring, raise the temperature above the melting point of copper (810.24k), and deoxidize after melting.

[0022] (1) For dehydrogenation, adjust the partial pressure of oxygen to a high level, the range of partial pressure of oxygen: 1.5atm~3atm. At the same time, keep the temperature adjusted to 50°C to 100°C above the melting point of copper, so that the oxygen element on the molten copper will increase, and the hydrogen will be separated regularly, so as to carry out the dehydrogenation process. The phase law here refers to the phase (balance) law, which is phase rule in English. Specifical...

Abstract

The invention provides a preparation method of a current collection sliding material. The preparation method comprises the steps of: step one. melting copper with high quality in an electric furnace, and degassing, thus forming copper melt; step two. melting iron with high quality in the electric furnace, and degassing, thus forming iron melt; step three. mixing the copper melt and the iron melt to form mixed melt, wherein the mixed melt comprises 20-40 parts of iron and 60-80 parts of copper in parts by weight; and step four. cooling, namely injecting the mixed melt into a mold to form ingot bars. A pantograph manufactured by using the current collection sliding material is used on carriages of high-speed railways in harsh environments and has good wear-resisting property and electrical conductivity.

Description

technical field [0001] The invention relates to a method for preparing a current-collecting sliding material, and also relates to the application of a product obtained by the method for preparing the current-collecting sliding material, which belongs to the field of metal materials. Background technique [0002] The pantographs of high-speed rail carriages used in harsh environments are usually made of sintered materials such as conductive metals and wear-resistant metals. This kind of sintered metal production method needs to go through multiple processing techniques in the past, and in order to achieve the specified performance, it needs to go through extremely complicated processes and management. These will greatly increase the price of the former pantograph. Contents of the invention [0003] The object of the present invention is to provide a method for preparing a current-collecting sliding material and the application of the product obtained therefrom, and to solv...
