Description

DESCRIPTION 0500987 Material flow mechanism of muffle roller type mesh belt quenching furnace

TECHNICAL FIELD The invention belongs to the field of material flow technologies, more particularly relates to a material flow mechanism of a muffle roller type mesh belt quenching furnace.

BACKGROUND Quenching is the most widely used method in steel heat treatment. There are four basic processes of steel heat treatment: annealing, normalizing, quenching and tempering. Annealing is to heat a workpiece to an appropriate temperature first, then choose different holding times according to the material and the size of the workpiece, finally slowly cool (the cooling speed is the slowest); the purpose of this process is to make the internal structure of the metal reach or approach the equilibrium state, thus obtaining excellent technological properties and service performance, or preparing the structure for further quenching. Normalizing is to heat a workpiece to a suitable temperature and then cool the workpiece in the air; the effect of normalizing is similar to that of annealing, except that the obtained microstructure is finer, so normalizing is often used to improve the cutting performance of materials, and sometimes used as the final heat treatment for some parts with low requirements. Tempering is to reduce the brittleness of steel parts; the quenched steel parts are kept at an appropriate temperature higher than room temperature but lower than 710°C for a long time and then cooled. Quenching means that the workpiece is heated and insulated, and then quickly cooled in quenching medium such as water, oil or other inorganic salts and organic aqueous solution. After quenching, the steel parts become hard but brittle at the same time. In order to reduce the brittleness of steel parts, the quenched steel parts are kept at an appropriate temperature higher than room temperature but lower than 650°C for a long time, and then cooled. Quenching furnace is a furnace that heats the workpiece before quenching, the heat source of the furnace may be electricity and fuel, and the temperature can be measured by thermocouple. The furnace using electricity, gas and liquid fuel can automatically control and adjust the temperature by instrument, and the quenching furnace is used for quenching the extruded products of aluminum alloy pipe side profiles. Before quenching, the extruded products should be heated evenly, and the temperature difference should be less than +2.5°C; when quenching, the transition time is required to be short, not more than 15 seconds. The quenching furnace is composed of furnace body, furnace 7500921 door, heating element, ventilation mechanism and control system. The furnace body is welded by structural steel and steel plates, the inner wall of the furnace lining is connected with the furnace housing by a stainless steel plate to form a whole, the furnace body and the furnace inner layer are filled with aluminum silicate refractory fiber for heat insulation. The muffle roller type mesh belt quenching furnace is widely used for batch carburizing, carbonitriding and quenching treatment of various small metal parts with protective atmosphere modulation.
