Problems solved by technology
The protective atmosphere produced by the direct instillation method is not completely cracked in the furnace, and carbon black is easily produced. The consumption of raw material gas is large, and a large amount of heat needs to be absorbed during the cracking process, which has a great influence on the temperature in the furnace. The protective atmosphere, the raw material gas is mixed with air in a certain proportion and then prepared by heating the catalyst. Although the raw material gas is reduced, the heating energy in the production process cannot be used, and the prepared gas must be cooled by water and regulated by refrigeration. Dew point, and then transported into the quenching furnace, will also have an impact on the temperature of the quenching furnace

The invention relates to a quenching furnace of a combined type protective atmosphere generating device which comprises a feeding frame, a heating chamber, a conveyor belt, a driving device and a protective atmosphere generating device arranged above the heating chamber of the quenching furnace in a combining way. The quenching furnace has the advantages that the protective atmosphere generating device is directly combined above the heating chamber of the quenching furnace, so that protective gas prepared by the protective atmosphere generating device can directly enter into the furnace, a great deal of heat of the prepared protective gas can be utilized, the temperature inside the furnace can not be influenced by the high temperature protective gas which enters into the furnace and absorbs the heat, and a great deal of generated heat energy also can be utilized; furthermore, the product quality is greatly improved, and the energy-saving effect is also obviously enhanced.
Description
Technical field: [0001] The invention relates to a combined protective atmosphere generator quenching furnace, which is mainly used for heat treatment such as quenching, carburizing and carbonitriding of various steel parts. Background technique: [0002] The protective atmosphere supply of the existing protective atmosphere quenching furnace is to use liquid or gaseous hydrocarbon fuel to be directly dripped into the furnace for cracking, or the protective gas is produced by a special generator device and then passed into the furnace as the protective atmosphere. . The protective atmosphere produced by the direct instillation method is not completely cracked in the furnace, and carbon black is easily produced. The consumption of raw material gas is large, and a large amount of heat needs to be absorbed during the cracking process, which has a great influence on the temperature in the furnace. The protective atmosphere, the raw material gas is mixed with air in a certain pr...
