Method for producing fire-fighting sprinkler head frame through semi-solid forming of brasses

Abstract

The invention discloses a method for producing a fire-fighting sprinkler head frame through the semi-solid forming of brasses. The method comprises the following steps: (1) selecting a brass raw material; (2) adding the raw material into a smelting furnace to heat, so that liquid slurry is obtained; (3) carrying out heat-retaining storage on the obtained liquid slurry, and controlling part of the slurry to convey; (4) after the slurry is conveyed to a casting preparation chamber, carrying out semi-solid temperature control on the slurry and controlling the one-time casting amount of the slurry; (5) carrying out stress relieving treatment, and carrying out casting forming on semi-solid brasses in a mold for producing fire-fighting sprinkler head frames; (6) cooling a formed part; and (7) carrying out finish machining on the formed part so as to obtain a finished product. Compared with traditional methods, no secondary heating for melting is required to be performed in the method, therefore, the method is energy-saving and environment-friendly; and according to the invention, parts are formed more rapidly, continuous casting is performed at higher speed, lower energy consumption is produced, the service life of the mold is long, the gas entrapment can be reduced in the process of production, castings have less cavities, and the strength is higher, therefore, the method is of great significance to the production of fire-fighting sprinkler head frames.

Description

technical field [0001] The invention relates to a metal semi-solid forming technology, in particular to a brass semi-solid forming method for producing fire sprinkler head frames. Background technique [0002] Research on high-performance and high-strength copper alloys has always been a hot spot in the field of copper metal research, and it has extremely wide applications in machinery, construction, hardware, electronics, sanitary ware and other industries. Fire sprinklers belong to the category of construction and public safety, and are mainly used in hotels, large public buildings and public places, etc., and are one of the important fire-fighting equipment. Fire sprinkler heads are easy to break, difficult to process, easy to corrode, and consume a lot of energy in production. [0003] At present, the production of fire sprinklers usually adopts traditional casting technology. Therefore, the metal needs to be melted twice, the energy consumption is large, and continuous...

Problems solved by technology

[0003] At present, the production of fire sprinklers usually adopts traditional casting technology. Therefore, the metal needs to be melted twice, the energy consumption is large, and continuous casting is not possible. At the same time, the product strength and pass rate are lower than those produced by semi-solid forming technology.
