The main problems in China coated sand detection is (1) detection means most companies are not perfect. Basic stay in detecting temperature strength, melting point, particle size and volume of the primary stage of hair; (2) domestic coated sand testing equipment accuracy and stability is not high regeneration coated sand production line offer the same kind of equipment of different manufacturers use in field conditions next, the detected coated sand performance indicators sometimes relatively large difference, such as room temperature tensile strength can be a difference of 10 kg or more, a difference of 5 ml or more gas evolution. Currently more advanced testing equipment including high temperature coated sand performance tester coated sand regeneration, send gas meter, hot strength tester coated sand recycling equipment, centrifugal casting the thermal process is in rough shape of the metal type (iron type) in the conventional centrifugal casting process, mainly for the production of Tube rotator casting, first in the iron mold cavity surface coated layer of paint in order to facilitate hanging modulo. In recent years, has developed a suitable alternative coating production centrifugal casting coated sand. Because of its exhaust is less effective, it requires a thin wall (about 3mm) coated sand recycling company, and often using double sand, and casting the contact surface with sand (70/140 mesh), the outer layer of coarse sand (50 / 100 mesh) coated sand recycling company, Shandong coated sand regeneration, provided by Qingdao Heng Heng Machinery Co., Ltd.
