Box-type gas carburizing furnace for metal heat treatment

Abstract

The invention relates to the technical field of carburizing furnaces, and discloses a box-type gas carburizing furnace for metal heat treatment. The box-type gas carburizing furnace for metal heat treatment comprises a base, a cover is fixed at the top of the base, a rotating column is rotatably connected to the top of the base and located on the inner side of the cover, and a plurality of carburizing grooves are formed in the top of the rotating column; and rotating discs are rotatably connected to the lower surfaces of the interiors of the carburizing grooves, a first motor is fixed to the center of the interior of the base, an output shaft of the first motor is fixedly connected with the bottom of the rotating column, a mounting block is fixed to the outer side wall of the base, a cylinder is fixed to the top of the mounting block, and a third rotating rod, baffles, a concave plate and leaking holes are arranged. In this way, heat-exchange water flows into a water tank from a water inlet cylinder, the water flows upwards and flows onto the concave plate through blocking of the baffles, the water is dispersed and flows downwards through the leaking holes in the concave plate, meanwhile, the third rotating rod and fan blades are driven through a first rotating rod and a first gear, the dispersed water is subjected to air cooling, and cooling is accelerated.

Description

technical field [0001] The invention relates to the technical field of carburizing furnaces, in particular to a box-type gas carburizing furnace for metal heat treatment. Background technique [0002] Heat treatment refers to a metal thermal processing process in which materials are heated, kept warm and cooled in a solid state to obtain the desired structure and properties. In the process of progress from the Stone Age to the Bronze Age and Iron Age, the role of heat treatment It is gradually recognized by people that metal heat treatment is one of the important processes in mechanical manufacturing. Compared with other processing techniques, heat treatment generally does not change the shape and overall chemical composition of the workpiece, but changes the microstructure inside the workpiece, or Change the chemical composition of the workpiece surface, endow or improve the performance of the workpiece. Carburizing furnaces are often used in the heat treatment of metals. C...

AI Technical Summary

Problems solved by technology

[0003] Existing box-type gas carburizing furnaces for metal heat treatment all use one furnace to work. Putting materials, heating carburizing, material cooling and taking out materials are all completed in one furnace, which affects the efficiency of the work, and when cooling , the cooling method is relatively simple, so the cooling is relatively slow
