Test situation of briquetting

1. Background
The briquetting is used in the casting and rolling production line. When in use, the briquetting is placed on top of the porous ceramic filter to prevent the alumina ceramic foam filter from floating during the casting and rolling process. The general service life is 3-6 months; the product needs to have sufficient density and a relatively high Low coefficient of thermal expansion, good thermal shock, and corrosion resistance; in order to solve the problems of easy cracking, poor thermal shock, and short service life in the production process of products, the production process of filter plate briquetting is optimized and upgraded.

During the production process, there are serious cracks. Cracks occur during use.
2. Control during the production process
1) In view of the background, in the past production, three materials were selected for laboratory experiments: A material with 6% water addition, B material with 5.5% water addition; C material with 7% water addition; embedded parts reduced from 8mm to 3mm. Three kinds of materials, two products of each material, one with embedded parts, one without embedded parts, and the amount of steel fiber added is 2.5%.
2) Production of embedded parts:

3. Use effect
Currently used in three units, no cracks appear, and the non-stick aluminum is good. It has been used for 4 castings for a month at the longest, and the product has no abnormalities.
