Rapid sintering system and rapid sintering method

Abstract

The embodiment of the invention provides a rapid sintering system and a rapid sintering method. The rapid sintering system comprises a furnace body, a lifting device, a temperature acquisition device,a control device and a partition plate component; the furnace body comprises a hearth and a furnace mouth which communicate with each other; the lifting device is arranged below the furnace mouth andcomprises a support and a sample table, wherein the sample table is arranged on the support; the temperature acquisition device is arranged on the sample table; the control device is arranged outsidethe hearth, is electrically connected with the lifting device and the temperature acquisition device, and is used for controlling the lifting device to ascend and descend according to the temperatureobtained by the temperature acquisition device and a preset sintering condition; and the partition plate component is arranged at the first end of the lifting device, a first interval is formed between the partition plate component and the sample table, and when the rapid sintering system is in a charging or discharging working condition, the partition plate component is used for blocking the furnace mouth. According to the rapid sintering system and the rapid sintering method, rapid sintering of a to-be-sintered sample can be realized, so that the sintering efficiency of the product is improved.

Description

technical field [0001] The invention relates to the technical field of dental material preparation, in particular to a rapid sintering system and a rapid sintering method. Background technique [0002] With the accelerated pace of people's life and the emergence of chairside CAD / CAM systems, in the current field of dental restoration, patients not only require high-quality dental restorations, but also hope to shorten the time spent on dental treatment. [0003] Zirconia and other ceramic materials have become widely used dental restoration materials in clinical treatment due to their good mechanical properties, chemical stability, biological safety, and aesthetic characteristics close to human natural teeth. However, restorations made of ceramic materials need to be sintered with heat treatment equipment such as sintering furnaces after being processed by cutting equipment such as computer-aided design and computer-aided manufacturing (CAD / CAM). In order for zirconia ceram...

Problems solved by technology

For example, the existing silicon-molybdenum rod or silicon-carbon heating element sintering furnace can achieve a temperature increase of about 20 degrees (Celsius) / minute at most, so that the sample to be sintered (here, the zirconia ceramic gum is taken as an example) is raised into the furnace. , it takes at least 80 minutes until the zirconia ceramic gums are sintered, and the sintering efficiency of the product is low
