Abstract

The invention discloses a sintering furnace. The sintering furnace comprises a base, a first hearth and a second hearth, wherein the first hearth and the second hearth are arranged on the base, a first fuel nozzle is arranged on the left side of the first hearth, a second fuel nozzle is arranged on the right side of the second hearth, a first flue is arranged on the back side of the first hearth, a second flue is arranged on the back side of the second hearth, one end of the first flue is communicated with the first hearth, one end of the second flue is communicated with the second hearth, a first flue switch device is arranged on the first flue, a second flue switch device is arranged on the second flue, the first hearth is connected with the second hearth through a channel device, a first air inlet device is arranged on the first fuel nozzle, and a second air inlet device is arranged on the second fuel nozzle. According to the sintering furnace, waste heat is brought into the second hearth through the channel device when sintering is conducted in the first hearth, so that a shell mold of the second hearth is preheated, in this way, cracks caused by direct high-temperature sintering can be reduced, and heat energy can be fully utilized to achieve energy saving.

Description

technical field [0001] The invention relates to the technical field of shell mold sintering in the foundry industry, in particular to a sintering furnace. Background technique [0002] Existing shell mold sintering furnaces in the foundry industry are all sintered in a single furnace. Such a design will waste a lot of heat and easily cause cracks in shell molds and other products, which are caused by the temperature difference from room temperature to high temperature. [0003] Therefore, it is necessary to design a sintering furnace that can save energy and prevent cracks in the product. Contents of the invention [0004] The invention proposes a sintering furnace, which solves the problems of insufficient energy saving and easy cracks in products in the prior art. [0005] Technical scheme of the present invention is realized like this: [0006] A sintering furnace, comprising a base and a first furnace and a second furnace arranged on the base, a first fuel nozzle is ...
