Description

Technical Field

[0001] The utility model relates to the technical field of pit-type carburizing furnaces, in particular to a pit-type carburizing furnace which is convenient for cleaning carbon black in the furnace. Background Art

[0002] Pit carburizing furnace is a gas carburizing treatment equipment used in the steel industry. Its main function is to infiltrate carbon atoms into the surface of steel parts to improve the surface hardness and wear resistance of parts. Pit carburizing furnace is widely used in the manufacture of parts that need to withstand heavy loads, friction, corrosion and other harsh conditions in industrial sectors such as automobiles, machinery, petroleum, chemicals, and electric power.

[0003] The commonly used pit carburizing furnace is not convenient for cleaning the carbon black in the furnace. After long-term use, the inner wall of the pit carburizing furnace is prone to accumulation of a carbon black layer, which slows down the heating speed of the pit carburizing furnace and deteriorates the carburizing effect on the metal.

[0004] Chinese patent CN209292460U discloses a pit-type carburizing furnace which is convenient for cleaning carbon black in the furnace. The utility model is provided with a hydraulic cylinder and a blade. The hydraulic cylinder can drive a hydraulic rod, a fixed frame and a blade to rise and fall. During the lifting and lowering process of the blade, the carbon black on the inner wall of the carburizing furnace can be scraped off, thereby facilitating the cleaning of the carbon black on the inner wall of the carburizing furnace.

[0005] However, when factories produce steel parts, they usually use pit carburizing furnaces with different inner diameters to meet different workpiece sizes and processing requirements. The fixed frame in the utility model is of fixed size and can only clean the inner wall of the pit carburizing furnace with the same inner diameter. When it is necessary to clean the pit carburizing furnace with an inner diameter larger than the size of the fixed frame, the staff needs to additionally manufacture a fixed frame that meets the specifications so that the blade can contact the inner wall of the pit carburizing furnace, and then the blade cleans the inner wall. This is too troublesome and easily causes unnecessary economic expenditure, so the utility model is proposed to solve the above problems. Utility Model Content
