ingot porosity
 

Aluminum alloy ingot porosity and porosity is one of the most common defects, aluminum smelting and casting technology (process rules) are generated around the pores and loose flaws developed. How to solve the [url=http://gsoftech.in/outdoor/106.html]hot sale wood shades 2x4 brackets[/url] problem of porosity and loose defects? Here are some cases may give you some inspiration. Case 1. There is an aluminum processing enterprise in the north.

When the oven is repaired, the thermocouple malfunctions and mistakes that it has reached the oven time and is put into production ahead of schedule. As a result, all four furnaces are scrapped for the simple reason (porosity is loose) In order to reduce [url=http://gobimarathon.org/square/4060-Myanmar-faux-panels-cost.html]Myanmar faux panels cost[/url] losses casting technicians brainstorming to take several measures: 1 is the delivery of solid material into the liquid material delivery (to shorten the melting time) 2 is to control the chemical composition of impurities (to reduce non-metallic inclusions) 3 is to strengthen the refining degassing 4 is the original small garden ingot specifications to large garden ingot (in order to reduce the casting speed, change over the belt size) the results to avoid losses.

Judging from the above case, although the incident has lasted for more than 30 years, it has provided very valuable [url=http://gsoftech.in/solid/1741.html]corrugated roof panels gazebo plans[/url] data and reference for our exploration and development in aluminum processing. Summary: 1. The use of liquid feed, reducing the metal in the furnace residence time, so that the gas dissolved in the furnace under the action of the unsaturated release and decomposition.

Strengthen the control of impurity components, effectively reduce the non-metallic slag inclusions increased. 3. Effective degassing refining, 4. Casting temperature using the upper limit, 5. Reduce the casting speed to change the liquid crystal transition zone structure, so that there is enough space for the remaining space, Casting process technology is not static, in the Under special circumstances, the decisive adoption of plans to prevent product [url=http://gobimarathon.org/square/2525-materials-for-exterior-balconies.html]materials for exterior balconies[/url] quality defects.
