Problems solved by technology
[0003] In order to solve the serious quality accidents caused by the rusting of bolts in the prior art, at the same time, the use of chemical blackening tempering furnace equipment has high energy consumption, serious pollution, large floor area, and the distribution of water vapor in the tempering furnace is not uniform enough, which affects the return of workpieces. In order to solve the problem of fire effect, the present invention provides a tempering furnace with a steam generating device. The water vapor is evenly distributed in the tempering furnace, so that the bolts can be oxidized and blackened in the tempering furnace

The invention discloses a tempering furnace with a water vapor generation device comprising the tempering furnace. A net belt for conveying workpieces is horizontally arranged in the tempering furnace. The tempering furnace with the water vapor generation device is characterized by further comprising a water vapor generator, the water vapor generator is connected with a water pump through a plurality of water inlet pipes, a flowmeter is arranged in each water inlet pipe, the top of the tempering furnace is provided with a plurality of air pipelines communicated with the tempering furnace, the air inlet of the air pipeline is communicated with the water vapor generator, and a fan is arranged close to the air outlet of the air pipeline in the tempering furnace. The invention solves the problems that bolt rustiness brings about the occurrence of serious quality accidents, the adopted medicament blackening tempering furnace apparatus has high energy consumption, serious pollution and large occupied area, the water vapors are not distributed uniformly in the tempering furnace and the workpiece tempering effect is influenced in the prior art. In the tempering furnace with the water vapor generation device provided in the invention, the water vapors are uniformly distributed in the tempering furnace so that bolts can be oxidized and blackened in the tempering furnace.
Description
technical field [0001] The invention relates to an improved device for a heat treatment process, in particular to a tempering furnace with a steam generating device. Background technique [0002] After the bolts are produced, the anti-rust performance is a very important technical indicator. If the bolts are rusted, it will cause many serious quality accidents such as assembly failure and fracture. At present, most of the equipment used in the market is a chemical blackening tempering furnace, which has high energy consumption, serious pollution, and occupies a large area. Existing bolt blackening mostly is blackening with medicament simultaneously, and water vapor blackening is never used at present. Contents of the invention [0003] In order to solve the serious quality accidents caused by the rusting of bolts in the prior art, at the same time, the use of chemical blackening tempering furnace equipment has high energy consumption, serious pollution, large floor area,...
