Independent heat-preservation bidirectional multi-layer roller hearth furnace

Abstract

The invention provides an independent heat-preservation bidirectional multi-layer roller hearth furnace. The independent heat-preservation bidirectional multi-layer roller hearth furnace comprises a furnace body, partition plates, front furnace doors and rear furnace door, wherein the furnace body is divided into a plurality of chambers which are arranged up and down by the partition plates, the front furnace door capable of being independently opened is arranged at the front end of each chamber, the rear furnace door capable of being independently opened is arranged at the rear end of each chamber, heating elements are arranged in the chambers, a plurality of ceramic rollers which are horizontally arranged are arranged in each chamber, and the two ends of the ceramic rollers are connectedwith the two side walls of the furnace body. Each chamber is provided with the front furnace door and the rear furnace door so that workpieces can enter from the direction of the front furnace doorsand exit from the direction of the rear furnace doors, the entering and exiting spaces of the workpieces are separated, the parts to be machined and the machined parts are not stacked in the same areaand are not easy to mix, meanwhile, the stacking area is also increased, and a material taking and placing manipulator can run in an independent space.

Description

technical field [0001] The invention belongs to the technical field of heating furnaces, and relates to an independent heat preservation bidirectional multi-layer roller hearth furnace. Background technique [0002] The heating furnace is an important part of the production line. At present, the conventional continuous roller hearth heating furnace and the multi-layer box-type resistance heating furnace are heated by resistance wire radiation heating. If the continuous roller hearth heating furnace is used to heat the plates in batches, the furnace body will be extended several times, the floor area will be large, and the cost will be high; the multi-layer box-type resistance heating furnace will also be unable to continuously heat the plates in batches due to low heating efficiency. The current multi-layer roller hearth furnaces are all connected with the upper and lower furnaces. Due to the continuous rise of heat, the temperature of the lower furnace is lower than that of...

AI Technical Summary

Problems solved by technology

If the continuous roller hearth heating furnace is used to heat the plates in batches, the furnace body will be extended several times, the floor area will be large, and the cost will be high; the multi-layer box-type resistance heating furnace will also be unable to continuously heat the plates in batches due to low heating efficiency.

The current multi-layer roller hearth furnaces are all connected to the upper and lower furnaces. Due to the continuous rise of heat, the temperature of the lower furnace is lower than that of the upper furnace, resulting in inconsistent temperatures in each furnace, which affects the quality of the workpiece.
