Problems solved by technology

[0004] Whether it is a push rod furnace or a roller hearth furnace, the furnace structure is a front-to-back through type, commonly known as a "tunnel furnace", and the heat loss at the entrance and exit of the furnace is large. There is a lot of heat loss; usually, after the spheroidizing annealing process is completed, the furnace temperature is 600-640°C, and the waste heat of the annealed parts is not utilized, which is the main reason for the high energy consumption of annealing

Abstract

the invention discloses a double-layer roll-bottom continuous-balling annealing furnace, which contains furnace, wherein the hearth consists of upper hearth and lower hearth, whose inlet and outlet are set on one end of furnace; the residual heat exchanging chamber is set near the furnace; the sealing rapid-cooling chamber is set in the furnace far away from inlet and outlet, which interconnects upper and lower furnaces; the upper driving roll is set on the upper furnace; the lower driving roll is set in the lower furnace; the elevator and pushing rod are set in the sealing rapid-cooling chamber; the upper heater and heat coupler are set in the upper furnace and lower heater is set in the lower furnace.

Description

technical field [0001] The invention belongs to the field of continuous spheroidizing annealing furnace equipment for heat treatment of metal materials, in particular to a double-layer roller bottom type continuous spheroidizing annealing furnace, which is suitable for energy saving and consumption reduction of spheroidizing annealing of parts made of bearing steel and alloy tool steel. Background technique [0002] In the prior art, spheroidizing annealing is divided into two categories: periodic annealing and continuous annealing. Periodic annealing uses trolley furnaces, bell furnaces, etc., which not only have unstable quality, but also high energy consumption; continuous annealing usually uses pusher furnaces and roller hearth furnaces, and the annealing quality is relatively stable, which can meet the national and industry standards The specified technical requirements, but there are still problems of high energy consumption. [0003] In ...
