Description

Technical Field

[0001] The utility model relates to the technical field of heating furnaces, in particular to a refractory castable heating furnace. Background Art

[0002] A heating furnace is a device used to heat objects or materials, usually using electricity, gas or other energy sources to provide heat energy. It is widely used in heat treatment, smelting, roasting and other processes in industrial production to change the properties or form of materials. There are many designs and types of heating furnaces that can be used in different temperature ranges and application areas.

[0003] A Chinese patent discloses a refractory castable heating furnace (publication number: CN213841747U). The material support plate arranged under the inner tank of the heating furnace is supported by a supporting steel plate, a supporting wheel and a wheel groove, which increases the stability of the movement of the material support plate. At the same time, the supporting transverse plate and the supporting longitudinal plate arranged on the upper surface of the material support plate facilitate the cooperation of the supporting transverse plate and the supporting longitudinal plate to support the material, thereby avoiding the problem of uneven firing caused by an excessively large material supporting surface. However, the device still has the following problems:

[0004] In the above device, the material pallet and the support steel plate carry the material above, but because the material pallet and the support steel plate need to move in coordination with the support wheels at the bottom, a larger opening needs to be opened when designing the heating furnace to allow the material pallet to be pulled out. When the heating furnace opening is opened for a long time, a large amount of heat in the furnace may be consumed. This results in the need to frequently preheat the material entering the furnace during the continuous processing of the refractory castable, thereby wasting fuel. Utility Model Content
