Background
The heat treatment furnace is an electric furnace or a fuel furnace for heating the charge for heat treatment. Commonly used heat treatment furnaces include a box-type resistance furnace, a pit-type resistance furnace, a gas carburizing furnace, a salt bath furnace, and the like.
A box type resistance furnace: the working principle is that current is utilized to generate heat through an electric heating element arranged in a hearth, and parts are heated through the current and radiation. It is a heating device widely applied in a heat treatment workshop. It is suitable for the annealing, normalizing, quenching, tempering, solid carburizing and other heating of iron and steel materials and non-iron and steel materials (non-ferrous metals). Has the advantages of simple operation, accurate temperature control, protective gas introduction for preventing the parts from being oxidized during heating, good labor condition and the like.
Well type resistance furnace: the well type resistance furnace has the same working principle as the box type resistance furnace, and is named after the shape of a well with the furnace mouth upward. Three types of well type furnaces of medium temperature, well type furnaces of low temperature and gas carburizing furnace are commonly used. The pit-type resistance furnace adopts a crane to hoist parts, so that the labor intensity can be reduced, and the pit-type resistance furnace is widely applied.
The medium temperature pit furnace mainly uses heat treatment of quenching, annealing, normalizing and the like of dry long parts, and the maximum working temperature is 950 ℃. Compared with a box furnace, the pit furnace has better heat transfer, a fan can be arranged on the top of the furnace, so that the temperature distribution is more uniform, and the bending deformation caused by the dead weight when the parts are horizontally placed can be overcome by vertically placing the slender parts.
Salt bath furnace: the salt bath furnace is a furnace type using molten salt as a heating medium. The salt bath furnace has simple structure, convenient manufacture, low cost, good heating quality and high heating speed, thereby having wide application. However, when the salt bath furnace is used for heating, the procedures of binding, clamping and the like of parts exist, the operation is complex, the labor intensity is high, the working condition is poor, and the defects of long temperature rise time during starting and the like exist. Therefore, salt bath furnaces are commonly used for medium, small and high surface quality parts.
