Vertical high temperature furnace having lifting device for testing

Abstract

The invention provides a vertical high temperature furnace having a lifting device for testing, which comprises a high temperature furnace main body and a ceramic hanger. A furnace cover is arranged at the bottom of the high temperature furnace main body; the ceramic hanger is located inside the high temperature furnace main body, and the ceramic hanger is mounted at the lower end of the furnace cover; the ceramic hanger is connected with the furnace cover through a sealing component; and a sample tray is arranged in the middle of the ceramic hanger. The ceramic hanger is orderly equipped withan upper furnace blocking tray, the sample tray and a lower furnace blocking tray. The sealing component comprises an annular silica gel sealing ring and a clamping slot; the clamping slot is arranged at the upper end of the ceramic hanger; the annular silica gel sealing ring is arranged in a furnace cover inner hole; and the annular silica gel sealing ring is clamped on the upper and lower sidesof the clamping slot. The vertical high temperature furnace having a lifting device for testing in the invention makes the high temperature furnace equipped with a stable lifting device; the ceramichanger is used as a carrier of a material, thereby improving the stability of the material fed into the furnace; meanwhile, the material can be taken out under a high temperature condition, thereby realizing rapid cooling of the material.

Description

technical field [0001] The invention relates to the technical field of high-temperature furnaces, in particular to a vertical high-temperature furnace for testing with a lifting device. Background technique [0002] With the development of science and technology, new materials have been widely studied, especially in the research of ceramic sintering, cemented carbide sintering and refractory materials, the experimental temperature needs to reach above 1200 ° C, and the atmosphere condition is also a factor that must be considered in the research . Therefore, high temperature furnaces with atmosphere control are widely used. [0003] Most vertical high temperature furnaces can control the heating temperature and atmosphere of the furnace. The requirements for the cooling process of the high-temperature furnace are too low, resulting in too long a furnace cooling time. For the placement of materials, most of them are suspended by high temperature resistant wires. After rep...

AI Technical Summary

Problems solved by technology

After repeated high-temperature burning, the brittleness of the high-temperature-resistant wire will increase, and it is easy to deform and break

At the same time, when the material is falling, it is easy to collide with the furnace wall, and the stability is not high during the lifting process, which affects the performance of the furnace
