Problems solved by technology

[0005] In addition, the existing cycle furnaces generally complete the process of heating and heat preservation during the day, and perform the process of cooling at night.
However, because the peak electricity price during the day is generally higher, the production cost of the existing cycle furnace is often high

Abstract

The invention relates to a multi-layer roller hearth waste heat utilization cyclic furnace and a waste heat recovery method applied to the multi-layer roller hearth cyclic furnace. The multi-layer roller hearth waste heat utilization cyclic furnace comprises a furnace body, an elevator, a vacuum ventilation chamber, a material inlet and outlet table, a transmission system and a control system. The transmission system comprises a transmission device which is connected with a motor. The material inlet and outlet table, the vacuum ventilation chamber, the elevator and the furnace body are sequentially connected. An electric furnace door is arranged between the furnace body and the elevator. A furnace shell is arranged outside the furnace body. Multiple heating bodies and at least two layers of in-furnace carrier rollers are disposed in the furnace body. The in-furnace carrier rollers of each layer are arranged on the transmission device. The control system controls forward and reversing transmission of the transmission device and ascending and descending of a lifting movable table. Compared with a continuous furnace and a cyclic furnace in the prior art, the multi-layer roller hearth waste heat utilization cyclic furnace has the advantages that charge capacity is large, the application range is wide, energy consumption for production is low and production efficiency is high.

Description

technical field [0001] The invention relates to a heat treatment furnace, in particular to a multilayer roller bottom waste heat utilization cycle furnace and a waste heat recovery method applied to a multilayer roller bottom waste heat utilization cycle furnace. Background technique [0002] Heat treatment furnace is a kind of equipment used for heat treatment of metal workpieces. According to the heating method, it can be divided into flame furnace and electric furnace. According to the thermal system, it can be divided into cycle furnace and continuous furnace. Among them, the continuous furnace refers to the continuous production of the furnace, the furnace is divided into temperature zones, and the workpieces gradually enter the temperature control zone from the preheating zone. The metal workpiece processed by the continuous furnace has the characteristics of smooth surface, uniform hardness and small deformation. However, the current continuous furnaces are all singl...
