preparation example Construction

[0047] A method for preparing tin-brass welding wire, the process steps comprising:

[0048] Step S1, melting: (1) using raw materials; main materials: electrolytic copper, zinc ingots, tin, auxiliary materials: slag cleaning agent, silicon;

[0049] (2) Feeding sequence: copper, silicon, zinc, tin;

[0050] (3) When the added material is melted and kept warm, take a sample test and adjust the composition according to the data of the test sheet;

[0051] (4) Raise the temperature after the ingredients are adjusted;

[0052] (5) Add an appropriate amount of slag cleaning agent after the temperature rise is complete, and then start to remove the ash and remove the slag. During the ash removal process, the copper ash spoon is required to stay at the furnace mouth for about 20 seconds when the ash is removed from the copper water, so as to ensure that the copper in the ash All the water flows into the furnace;

[0053] (6) Measure the temperature in the furnace after the ash re...

Embodiment 1

[0062] The raw materials are batched according to the ratio, and the batching sequence is: copper, silicon, zinc, tin, and the materials are added for melting. When keeping warm, sampling and testing are carried out, and the ingredients are adjusted according to the data of the test sheet. After the ingredients are adjusted, the temperature is raised. , the method of judging the temperature increase without ash and slag removal is to look at the direction of the pointer of the furnace ammeter. When the pointer reverses violently, the temperature has reached the state of temperature increase. In the process of ash removal, the copper ash spoon is required to stay at the furnace mouth for about 20 seconds when the ash is removed from the copper water, so as to ensure that all the copper water in the ash flows into the furnace. When the ash removal is complete Measure the temperature in the furnace. If the temperature is not enough, you need to raise the temperature again. The met...

Abstract

The invention provides a tin brass welding wire. The tin brass welding wire is prepared from the following components in percentage by weight: 59%-61% of copper, 0.8%-1.0% of tin, 0.15%-0.35% of silicon and the balance of zinc. According to the tin brass welding wire and a preparation method thereof, the defects in the prior art are overcome, the machining process is very complete, the machining effect is good, the production requirement can be met conveniently, and the tensile strength is high and is improved by 20%-30% compared with a welding wire machined through a common method; and the tin brass welding wire is high in hardness, can bear large pressure, can be widely applied to brazing, copper, steel, copper-nickel alloy, gray cast iron, inlaid hard alloy cutters and the like, and canalso be used as a surfacing material for low-pressure valve seal and light-load N-grinding surfaces, the performance of welding wire products can be improved through a reasonable proportion of Sn andSi in the tin brass welding tire, the fluidity, strength and corrosion resistance of the welding wire are improved through Sn, Si controls evaporation of zinc, and air holes are eliminated.

Description

technical field [0001] The invention relates to a welding wire, especially a tin-brass welding wire and a preparation method thereof. Background technique [0002] The production of tin brass wire has a history of more than 50 years in our country, and its production process is actually the processing and production process of tin brass wire. [0003] At present, the processing technology of tin-brass welding wire on the market is still immature, the processing technology is not complete, the processing effect is poor, and it is far from meeting the production demand. [0004] Therefore, it is necessary to provide a tin brass welding wire and a preparation method thereof to solve the above technical problems. Contents of the invention [0005] Purpose of the invention: Aiming at the problems in the prior art, the present invention provides a tin-brass welding wire and its preparation method. The processing technology is very complete, the processing effect is good, and it...
