Abstract
The technology of production of die tooling based on high-alumina cement, used for the manufacture of aluminum alloys, transforming into a plastic state at high temperatures, is considered. This technology is based on the sol-gel method, characterized in that the formation of a crystalline high-strength structure for die tools based on high-alumina cement occurs cyclically with stage exposure at certain temperatures. First, a sol is formed-a free dispersed system, then a gel structure-a bound dispersed system. The final structure is crystalline, high strength with a compressive strength of up to 180-190 MPa. A distinctive feature is the possibility of destruction of the form after the manufacture of products. This is necessary because the manufactured products have a developed geometric shape and the product can not be obtained from the mold by ordinary removing the formwork.
