Abstract

The invention discloses a ceramic shaft rod sintering process. The process employs a corundum sagger and a bottom bearing plate. The ceramic shaft rod sintering process provided by the invention solves the bending phenomenon of long shaft rod products prepared from alumina and zirconia ceramics during sintering, changes from existing flat sintering to vertical standing sintering, field certification proves that the process can achieve good effect, the product straightness qualification rate is increased from original about 80% to 98%, also the process greatly improves the sintering capacity, and reduces the sintering energy consumption of single product, thereby lowering the production cost of enterprises.

Description

technical field [0001] The invention relates to the field of ceramic sintering, in particular to a sintering process for solid or hollow ceramic long-axis rods made of alumina or zirconia. Background technique [0002] In order to ensure the straightness requirements of the shaft and rod products after sintering, the existing technology mainly adopts the corundum flat sintering or hanging sintering method to ensure the straightness of the product is below 0.4mm; To ensure the straightness of the product; hanging sintering mainly uses the vertical line of the center of gravity of the product and the axis of the product in one direction to ensure the straightness of the product after sintering. [0003] The main problems of lying flat sintering: [0004] 1) The requirements for the supported corundum flat plate are extremely high, and the flatness of itself is required to be below 0.2mm; [0005] 2) The durability requirements for corundum slabs are also extremely high. The ...
