Well-type furnace is a common industrial furnace. Its structural feature is that the furnace body is well-shaped, the furnace is inside the well, the combustion chamber is outside the well, and the upper part of the furnace body is equipped with a heater and a flue gas discharge port.Atmospheric Pressure and Vacuum Sintering of High Purity Dense MgO Ceramics Pit furnaces are widely used in heat treatment, sintering, pyrolysis, drying and other industrial fields. According to different application scenarios and process requirements, well-type furnaces can be divided into the following categories.Vacuum Brazing solutions for Cutting and Grinding Tools Heat treatment pit furnace is a common type of pit furnace, mainly used for heat treatment of metal materials. The interior of the heat treatment pit furnace is usually made of refractory materials, which can withstand high temperature and high pressure environment. Alumina ceramic densely sintered The heating methods of the heat treatment pit furnace include electric heating, gas heating and other forms, which can meet the heating needs of different materials. Heat treatment pit furnaces are widely used in iron and steel, non-ferrous metals, machinery manufacturing and other industries.The characteristics and working principle of vacuum heat treatment furnaces
