The Matters for Attention For Ductile Cas
Ductile castings in production, which should be followed when pouring temperature, the principle of low temperature pouring. For improve the melt temperature of liquid metal to completely melt inclusions, slag buoyancy, convenience of slag r...
Optimization of Ductile Casting Quality C
In order to ensure ductile casting quality, in production must pay attention to the following questions:1 ladle, casting tools, furnace pretreatment with inoculant, nodulizing agent before use must be fully dry, dry before use.2 pouring pers...
The Role of Nickel Element In Gray Cast I
The role of Ni (Ni) elements in cast iron:1. Miscible with liquid iron and ferrite2. During the eutectic promote graphitization, its effect is equivalent to a third si3. Reduce the austenite transformation temperature, expand the austenite z...
The Role of Trace Elements In Grey Cast I
The role of copper, tin, antimony, in cast iron:Cu (copper)1. Dissolved in the austenite limit of 3.5% (when the carbon is 3.5%)2. Promote the graphitization eutectic phase, ability of about 1/5 of the silicon3. Reduce the austenite transfor...
The Influence of Metal Temperature on The
In investmentcasting process, especially in the axis such as process, the metal temperature is the dominant factor, therefore, also to a lot of quality has a direct impact.If improper measurement and control, metal temperature difference on...
The Role of Cr and Mo In The Gray Cast Ir
Cr (Cr)1. In the graphitizing effect is strong, stable pearlitic eutectoid transformation2. The elements of chromium is narrowing the gamma area, Cr20 %, gamma area disappear3. The dosage of 0.15% 30%4. The amount is less than 1.0% is still...
The application of the manipulator in the
With the continuous development of modern foundry industry, for the castings and the requirement of increasing the production efficiency, this is for casting industry will constantly improve the automation level, application in foundry indus...
The Matter Needing Attention Pouring Gray
In pouring castings (particularly iron), should notice:A slow steady fast, at the beginning of the casting for castings, especially just contact foam liquid metal in the shape of the moment, when the sprue not full or just started pouring of...
Prevention of Ductile Deformation of Cast
A hoisting ductile casting slab in order to prevent deformation in ductile casting slab.Want to use the four elements of the same length of wire rope and ductile casting slab in the top four lifting holes, the ductile casting slab stationary...
The Application of Manipulator for Invest
1, precision casting, shell making robots This manipulator can be completed in turn on coating, sanding, drying and other steps, and can automatically collect information of each part, and feedback to the computer.2, sandblasting manipulator...
