High temperature electric heating furnace for furnace body replacement and rapid material cooling

Abstract

The invention relates to a high temperature electric heating furnace for furnace body replacement and rapid material cooling. The high temperature electric heating furnace for the furnace body replacement and rapid material cooling comprises an electronic control system, a heating furnace body, a vacuum atmosphere system and a water cooling system. A replaceable furnace body structure is adopted to adapt to the different protective atmosphere required for different materials, vacuum, inert gas, reducing gas, oxidizing gas, nitrogen and other protective atmospheres can be separately heated at high temperature on one equipment. A function of rapid cooling is further provided, parts can be quickly cooled under the protection of protective atmosphere, and the requirements of heat treatment process of different parts are met. The device has the advantages of compact massive structure, powerful function, high production efficiency, high heating temperature, high monitoring ability and the like, and is suitable for atmosphere sintering and heating production of various materials of different properties.

Description

Technical field [0001] The invention relates to the technical field of electric heating furnaces. Specifically, it is a high-temperature electric heating furnace that can replace the furnace body and quickly cool the material. Background technique [0002] In industrial production, many materials need to be heated in a certain atmosphere and pressure environment. Materials with different properties need to be heated in an atmosphere of different nature and under different pressures to obtain products of corresponding quality and performance. This requires the heating furnace to be able to adapt to multiple protective atmospheres such as vacuum, oxidation, reduction, and inertness. . The electric heaters commonly used in high-temperature electric heating furnaces with heating temperatures above 1400°C include silicon molybdenum rods, molybdenum wires or molybdenum rods, tungsten wires or tungsten rods, and zirconium diboride heating elements. The normal working atmosphere of di...

Problems solved by technology

In order to ensure the effect of atmosphere protection, most of the current high-temperature vacuum atmosphere furnaces do not have a cooling system, and can only be cooled with the furnace in a sealed atmosphere protection environment, resulting in slower cooling speed and lower production efficiency.

In addition, high-temperature vacuum atmosphere furnaces work under airtight conditions, and the specific heating conditions and temperatures of the internal parts of the furnace cannot be seen from the outside
