Carburizing furnace for metal forging heat treatment and operation method thereof

Abstract

The invention relates to the technical field of carburizing furnace equipment, in particular to a carburizing furnace for metal forging heat treatment and an operation method thereof. The carburizingfurnace comprises a box type double-layer heat insulation furnace body, a first roller conveyor, second roller conveyors, a carbon powder quantitative dispenser, an adjustable hot air circulation mechanism and auxiliary circulators. The two sides of the box type double-layer heat insulation furnace body are provided with switch sealing gates for feeding and discharging, the box type double-layer heat insulation furnace body is further internally provided with an electric heating plate, and the top end of the electric heating plate is further provided with an air inlet pipe communicating with the interior of the electric heating plate for balancing the pressure intensity in the furnace; the first roller conveyor is arranged at the bottom end inside the box type double-layer heat insulationfurnace body, and the second roller conveyors are arranged at the two ends of the first roller conveyor in the same direction and are positioned outside the box type double-layer heat insulation furnace body; the carbon powder quantitative dispenser is arranged at the top end of the box type double-layer heat insulation furnace body, and the output end of the carbon powder quantitative dispenser communicates with the inside of the box type double-layer heat insulation furnace body; the working end of the adjustable hot air circulation mechanism is arranged inside the box type double-layer heatinsulation furnace body; and the auxiliary circulators are arranged on the two sides of the box type double-layer heat insulation furnace body. According to the device, carburizing treatment is uniform, and feeding and discharging are convenient.

Description

technical field [0001] The invention relates to the technical field of carburizing furnace equipment, in particular to a carburizing furnace for metal forging heat treatment and an operation method thereof. Background technique [0002] Carburizing is the process of infiltrating carbon atoms into the surface layer of steel. It is also to make the workpiece of low carbon steel have a surface layer of high carbon steel, and then after quenching and low temperature tempering, the surface layer of the workpiece has high hardness and wear resistance, while the central part of the workpiece still maintains the toughness and toughness of low carbon steel. plasticity. [0003] The carburizing furnace is a new type of energy-saving periodic heat treatment electric furnace, which is mainly used for gas carburizing of steel parts. Due to the selection of ultra-light and energy-saving furnace lining materials (ceramic fiber) and advanced integrated sealed fans for water-cooled furnace...
