The characteristics and development of trolley heating furnace

The structural characteristics of the trolley furnace are: it has a chamber-type furnace, and the bottom of the furnace is a movable trolley. The workpieces are arranged on the special pad iron evenly distributed on the surface of the trolley. HIGH SPEED CIRCULAR SAWING MACHINE HY-100NC When heating, the trolley is pulled into the furnace by the traction mechanism. ; After heating, the trolley is pulled out of the furnace to unload by the traction mechanism.Precision carburizing heat treatment of gears The heating of the trolley-type heating furnace adopts variable temperature intermittent heating. Compared with the continuous heating furnace, the heat storage loss of the trolley-type furnace is greater. Due to the small temperature difference between the furnace temperature and the workpiece temperature, the heating speed of the furnace is relatively slow. Furnaces are less thermally efficient. Due to the high furnace temperature of the trolley-type heating furnace, flame furnaces are generally used for heating, and natural gas, coke oven gas, producer gas, fuel oil, and coal can be used as fuels for heating. In recent years, with the renewal of my country's energy quality and environmental protection requirements, the use of clean energy such as natural gas instead of fuel and coal has become a development trend. At the same time, the use of clean energy has brought a new development to the temperature control of the trolley heating furnace.HIGH SPEED CIRCULAR SAWING MACHINE HY-120NC
