Top Quanlity High Precision Aluminum Alloy DI Density Testing Machine MAY-ME204E-DI
Overview
Hydrogen is a large amount of gas dissolved in liquid aluminum. Due to the presence of hydrogen, aluminum castings are prone to pinholes, pores and other defects, which will cause the mechanical properties and internal quality of the castings to be greatly reduced. With the development of the automobile and aviation industries, people attach great importance to the quality and reliability of aluminum alloys. Therefore, it is very important to accurately measure the hydrogen content in molten aluminum before pouring, so as to ensure that the molten aluminum is degassed and refined. Control the hydrogen content within the allowable range.
Principle
MAYZUM brand aluminum liquid qualitative hydrogen measuring instrument is based on the principle of reduced pressure solidification method to measure the hydrogen content in cast aluminum liquid. This equipment uses vacuum extraction technology to quickly precipitate hydrogen in the liquid sample. After the sample is solidified , You can determine whether the hydrogen content of the aluminum liquid meets the requirements by comparing the surface quality of the sample with the standard sample; also can quickly measure the density equivalent value (DI value) of the test block through the intelligent density equivalent meter. To determine whether the molten aluminum meets the requirements. Since the molten aluminum is solidified in a vacuum, the whole solidification process is not affected by the outside air. The hydrogen content of the measured sample is the hydrogen content of the crucible when it is sampled. This equipment has the advantages of accurate detection, reliable operation, easy operation, simple maintenance, etc. It is an ideal equipment for aluminum castings to detect the hydrogen content of molten aluminum. MAYZUM Liquid Aluminum Hydrogen Tester is helpful to qualitatively analyze the quality of molten aluminum and determine the quality of molten aluminum initially. It is an ideal equipment for evaluating the degassing effect, molten aluminum quality and smelting treatment process. This equipment helps reduce product waste Rate, reduce the consumption of energy, materials, manpower and material resources.
Application
Used for quality control in the production of aluminum and aluminum alloy casting, melting site inspection, especially in front-furnace casting or aluminum processing sites with multiple holding furnaces, such as aluminum castings, aluminum profile processing, inspection of molten aluminum quality, and calculation of molten aluminum density Analyze the hydrogen content of molten aluminum to evaluate the refining effect.
Features
1. Smooth and silent wheels, easy to move with one hand, can detect the gas content of molten aluminum in different fixed positions, one machine for multiple purposes
2. One-key direct reading of density value, hydrogen content (%)/DI value, fast printing of measurement reports, fast analysis speed, in the on-site environment of the foundry workshop, the hydrogen content analysis of molten aluminum can be completed within 5 minutes.
3. The test results are true and credible and have good repeatability. Combining several analysis methods can make accurate judgments on the quality of molten aluminum and guide production in a practical and reliable manner.
4. All parts of the instrument are assembled with card positions, all screws are internally locked, beautiful appearance, stable structure, imported casters with damping, easy to move.
5. The operation is simple and safe to use, without too much experience requirements for the operator, simple training, you can use it correctly (the operating instructions are attached).
6. The vacuum chamber is located above the instrument and is made of stainless steel. It is composed of a vacuum cover and a lower sealing device. The vacuum chamber is equipped with a silencer. The vacuum cover uses a stainless steel bell jar with a thickness of ≥15mm. The top of the vacuum cover is equipped with a 10mm thick high temperature resistant visual The window is convenient to observe the changes of the sample in the vacuum chamber. The vacuum cover meets the characteristics of high temperature resistance, fast heat dissipation, not easy to damage, and durability;
7. The operating table is made of 304 stainless steel, and is equipped with high temperature resistant fiber mats. It is beautiful, high temperature resistant and durable, suitable for the complex environment in front of the furnace.
