Embodiment 1

[0022] The smelting process of babbitt wire comprises the following steps:

[0023] a. First put 6% copper material into the graphite crucible or stainless steel pot of the intermediate frequency smelting furnace, then put 11% antimony material into the graphite crucible or stainless steel pot of the smelting furnace, and then stir;

[0024] b. After the copper material and antimony material are melted, put the remaining tin material into the graphite crucible or stainless steel pot of the smelting furnace;

[0025] c. Control the temperature of the smelting furnace at 900°C, then fully stir for 10 minutes and add hydrogen chloride solution to remove impurities;

[0026] d. Raise the temperature of the smelting furnace to 1020°C, then fully stir for 10 minutes and add rosin;

[0027] e. Lower the temperature of the smelting furnace to 650°C, add the arsenic material and fully stir for 10 minutes;

[0028] f. Inject the smelted liquid babbitt alloy into the mold, and form sol...

Abstract

The invention relates to a smelting technique of a Babbitt metal wire, which comprises the following steps: sequentially feeding copper, antimony and tin, smelting at high temperature, and sufficiently stirring to finally obtain the Babbitt metal, of which the flexibility and crystalline phase structure are greatly enhanced. The invention ensures that no frequent cracking can appear when the Babbitt metal is finally extruded into the wire through a screen, and solves the problem that the Babbitt metal can not be prepared by the prior art. By using the smelting technique of the Babbitt metal wire, the Babbitt metal can be used more widely.

Description

technical field [0001] The invention relates to a smelting process, in particular to a smelting process of Babbitt wire. Background technique [0002] Babbitt is the most widely known bearing material, a tin- and lead-based bearing alloy with antifriction properties. Babbitt alloys are mainly used in bearing pads, bearings, bushings and bushings of large mechanical spindles. However, the existing Babbitt alloy has the characteristics of poor flexibility, so frequent fractures will occur during wire drawing. Therefore, prior art also can't make babbitt into wire shape. Contents of the invention [0003] The present invention is proposed to solve the disadvantages of poor flexibility of Babbitt alloy and inability to make wire-like Babbitt alloy in the existing Babbitt alloy smelting process, and aims to provide Babbitt alloy which can be made into wire-like Babbitt alloy. Alloy wire smelting process. [0004] In order to solve the above technical problems, the present i...
