Calcinator used for turbine investment casting

Abstract

The invention relates to a calcinator used for turbine investment casting. The calcinator includes a calcinator body and a transporting rail (1) which passes through the calcinator body. The calcinator body includes, from front to back, a jet-burning zone (2), a thermal-insulation zone (3) and a heating zone (4). Two first spray guns (5) are disposed respectively at both two sides of each of the jet-burning zone (2), the thermal-insulation zone (3) and the heating zone (4). A top of each of the thermal-insulation zone (3) and the heating zone (4) is provided with a second spray gun (6). The interior of each of the jet-burning zone (2), the thermal-insulation zone (3) and the heating zone (4) is provided with a temperature sensor (7). Because that the interior of each of the jet-burning zone, the thermal-insulation zone and the heating zone is provided with the temperature sensor, working situations of the first spray guns and the second spray guns can be adjusted by means of real-time temperature monitoring during a practical working process. The calcinator used for turbine investment casting is high in temperature-controlling precision and can improve production quality.

Description

technical field [0001] The invention relates to a baking furnace for turbine investment casting, which belongs to the technical field of turbine manufacturing. Background technique [0002] In the manufacturing process of the turbine, investment casting of the turbine mold shell is required. The mold shell needs to pass through the roasting furnace when the mold is invested. The traditional roasting furnace has inaccurate temperature control, which leads to the inaccurate temperature of the mold shell released from the furnace, resulting in the next Pouring process product quality declines. Therefore it is particularly important to seek a baking furnace for turbo investment casting with higher temperature control accuracy and improved product quality. Contents of the invention [0003] The object of the present invention is to overcome above-mentioned deficiency, provide a kind of baking furnace for turbo investment casting with high temperature control accuracy and impro...
