Adhesion process of mouthed crucible

Abstract

The invention discloses an adhesion process of a mouthed crucible. The adhesion process is characterized in that a crucible which is produced by adopting an isostatic pressing technique is taken as an adhered object, and the adhesion process comprises the following steps: (1) reasonably forming a groove in a semi-finished crucible blank body according to the size of a to-be-adhered mouth; (2) forming a unilateral groove in an adhering surface to enhance the fracture resistance of an adhered position and amending the appearance; (3) drying, glazing and sintering the grooved semi-finished crucible and the mouth according to the process to enhance the hardness of the blank body; (4) removing the glaze layer from the surface of an adhered end after sintering; and grinding and roughing the adhering surface; (5) uniformly coating the adhering surface with an adhesive and pressing the adhered position, and then naturally drying for 48 hours; (6) glazing the adhered position and then sintering again to finish the adhesion process. The adhesion process disclosed by the invention has the advantages that 1, the adhesion process can be used for producing mouthed crucibles with different sizes according to the needs of customers; 2, the adhered position can resist a high temperature, corrosion and extrusion of external forces; 3, the mouthed crucible looks smooth and flat after the adhered position is amended.

Description

technical field [0001] The invention relates to the field of crucible preparation, in particular to a bonding process for a mouthed crucible. Background technique [0002] The crucible is an important part of the smelting furnace, it is the space for melting and refining metal liquid, and it is the basis for ensuring the smooth progress of smelting. There are many models and specifications of the crucible, and the application is not limited by the production scale, batch size and the variety of smelted substances. It can be selected arbitrarily, has strong applicability, and can guarantee the purity of the smelted substances. Crucible production raw materials can be summarized into three types. One is crystalline natural graphite, the other is plastic refractory clay, and the third is calcined hard kaolin-like skeleton clinker. Since 2008, high temperature resistant synthetic materials have been used as the skeleton clinker of the crucible, such as silicon carbide, alumina...
