Method for producing ultrahigh pressure switch pressure-bearing aluminum alloy tanks under low pressure through V method

Номер: CN102941333A
Автор: Xu Tongsheng, Zhao Songqing, Wang Hongwei, Yang Huanqiao
Принадлежит:

The invention discloses a method for producing ultrahigh pressure switch pressure-bearing aluminum alloy tanks under low pressure through a V method in the technical field of vacuum casting, which comprises the following processing steps: jig manufacture, low-temperature gating system manufacture, upper tank molding, lower tank molding, lower core mould assembling, casting and pressure removing and picking. The method solves the defects of slag inclusion, pores, pinholes and the like of cast caused by intensive scouring of molten metal to cast, and simultaneously can solve the problems that the cavity casting system occupies excessive molten metal, and particularly the product yield of cast with low wall thickness and large size is low.

Принадлежит:

The invention provides a red copper melting process with increased conductivity. The red copper melting process comprises the following steps of: before melting, respectively brushing coating on all melting tools to prevent the pollution to a copper liquid in the melting process; taking charcoal subjected to high temperature carbonization as a covering material to isolate the contact between the copper liquid and the outside and prevent the oxidation and gas suction; adding a proper amount of phosphor copper for deoxidizing; adding a proper amount of pure magnesium for secondary deoxidization; adopting CaB6 for deoxidizing; and finally, adopting Li for final deoxidization. On one hand, the content of gas is reduced to be lower, the impurities are further removed and the conductivity is increased. The red copper melting process disclosed by the invention has the advantages of simpleness and convenience in operation, visuality, conciseness, improved production quality and favorable marketing ...

Hydrate reaction kettle suitable for direct measurement in terahertz spectrum

Номер: CN103245540A
Автор: Zhao Kun, Shi Hongjie, Zhao Songqing
Принадлежит:

The invention relates to a hydrate reaction kettle suitable for direct measurement in a terahertz spectrum. The reaction kettle comprises a cooling housing which consists of a shell and a through type pipeline transversely arranged in the shell. A seal chamber for accommodating a cooling medium is formed between the outer wall of the pipeline and the shell. A first quartz window and a second quartz window are axially and fixedly arranged in the pipeline at an interval, and the quartz windows are hermetically and fixedly connected with the inner wall of the pipeline. A hydrate generation space is formed between the first and second quartz windows and is hermetically communicated with a gas supply tube and a water supply tube. The reaction kettle further comprises a pressure sensing element and a temperature sensing element for monitoring the pressure and temperature in the hydrate generation space. The reaction kettle integrates production and measurement of hydrate, and the hydrate generated ...
