Abstract

The invention provides an energy-saving electrical burning nitriding furnace which comprises a steel structure outer wall, wherein a kiln wall, a kiln car and a kiln top are arranged in the steel structure outer wall; one or multiple rows of electrical heating components are arranged in the middle of a kiln. The energy-saving electrical burning nitriding furnace provided by the invention has the advantages that one or multiple rows of electrical heating components are adopted, and the most or all energy radiated by the central electrical heating component can be absorbed by sintered finished products, thus the energy-saving effect is better; the kiln top is designed as an arch or plane shape, the section of the kiln is increased, the product load and production efficiency of a single furnace are improved, and the capitalized cost is lowered; and the production cost is effectively lowered, the energy is saved, better economic benefits and social benefits are obtained.

Description

technical field [0001] The invention relates to a kiln, in particular to an energy-saving electric-fired nitriding furnace. Background technique [0002] Due to the limited radiation distance of the electric heating energy in the above-mentioned traditional furnaces that use electricity as energy, the electric heating radiation section generally does not exceed 1.5 meters, and the volume is small within the limited length, and part of the electric radiation energy is stored and emitted by the furnace wall. , making the investment cost high and the energy consumption large. Contents of the invention [0003] The object of the present invention is to provide an energy-saving electric-fired nitriding furnace, which can reduce investment costs and energy consumption. [0004] In order to solve the above-mentioned technical problems, the technical solution of the present invention is as follows: an energy-saving electric-fired nitriding furnace includes a steel structure outer...
