Design Integration and Analysis of Arduino Operated Gas Nitriding Furnace

Abstract

Nitriding is a process in which the materials are hardened at a temperatureof 400℃ to 900℃. This gas nitriding furnace is designed to be compact, automated, appropriate for all atmospheric conditions, and equipped with a configurable instrumentation system for automation. The Automated Gas Nitriding Furnace is designed and studied using the principle of heat transfer. It was created for experimental reasons. The furnace that can produce nitrogen at a specific temperature in a contained space under ideal working circumstances. The refractory bricks are formed between sheets of low carbon steel that make up the furnace. In the CREO 3D Modelling software, the components of the Gas Nitriding Furnace are modelled with all of the furnace's dimensions, and the modelled components are built in the same 3D modeling program.  The draft sheets used to create the Gas Nitriding Furnace provide the output of the simulated furnace. The software Ansys Workbench 2022 R2 analyzes the total deformation and thermal stresses using static structural analysis and steady state thermal analysis. The instrumentation for the furnace is controlled and automated in this project using an Arduino and IoT technology. In the gas nitriding furnace, the temperature, voltage, gas mixture ratio, and pressure are all automatically controlled. The NodeMCU ESP8266 Microcontroller controls the furnace from a distance.
