Brief introduction and application of regenerative trolley type heat treatment furnace:


The regenerative trolley type heat treatment furnace belongs to the intermittent variable temperature furnace, and the furnace is not divided into zones. The furnace temperature of the trolley type heat treatment furnace changes with time according to the specified heating procedure, which is used for the heat treatment of rolled materials, castings and forgings. The temperature of trolley type heat treatment furnace is generally 700-1200 degrees, and the process operation cycle is long. A kind of


Characteristics of regenerative trolley type heat treatment furnace:


The structural characteristics of the regenerative trolley type heat treatment furnace are as follows: it has a chamber type furnace, the furnace bottom is a movable trolley, and the workpieces are arranged on the special sizing block evenly distributed on the trolley surface. When heating, the trolley is pulled into the furnace by the traction mechanism; after heating, the trolley is pulled out of the furnace by the traction mechanism for discharging, and the regenerative trolley type heat treatment furnace is divided into combustion chamber or burner arrangement Side burning type, bottom type and circulation type. To be careful


The regenerative trolley type heat treatment furnace can be divided into upper exhaust and lower exhaust according to the exhaust way. During the upper exhaust, the flue gas is concentrated from the top of the furnace or the metal flue pipe or sent to the outside of the plant respectively. The furnace bottom of the upper exhaust can be overhead. The masonry has small heat storage, fast temperature rise and is not limited by the underground water level, but the metal flue pipe and chimney are easy to be damaged


Because the regenerative trolley type heat treatment furnace generally uses the flame furnace for heating, the heating fuel can be natural gas, coke oven gas, generator gas, fuel oil, coal and other fuels, and electric heating can also be used. The temperature difference in the trolley type heat treatment furnace is not large, so the heating speed is slow, the furnace is usually intermittent operation with variable temperature, and the heat storage loss of the furnace body is large. In addition, the sand seal of the trolley is not easy to be tight, and the heat loss of the trolley out of the furnace is large. Due to the low thermal efficiency of the furnace, the thermal efficiency of the brick masonry trolley heat treatment furnace is about 15%, but the thermal efficiency of the trolley type heat treatment furnace with refractory fiber furnace wall and automatic control can reach about 40%.. To be careful


In recent years, as the energy and emission are paid more and more attention by the state and enterprises, the requirements for the application of new technology of trolley type heat treatment are also higher and higher. The trolley type heat treatment furnace adopts full fiber furnace lining, with small heat storage capacity and less heat loss, so as to speed up the heating speed of the furnace.
