Abstract

The invention belongs to the technical field of metallurgical equipment and discloses a tunnel kiln device suitable for the iron smelting technology. The tunnel kiln comprises a kiln body, a rail penetrating the kiln body and kiln cars arranged on the rail. The tunnel kiln comprises a drying section, a preheating section and a roasting section in the length direction of the kiln body. The working temperature of the drying section ranges from the normal temperature to 80 DEG C. The working temperature of the preheating section ranges from 80 DEG C to 600 DEG C. The working temperature of the roasting section ranges from 600 DEG C to 1500 DEG C. The tunnel kiln device is used for drying, preheating and roasting furnace burden briquettes, so that the requirement for smelting is met, energy consumption is low, and environment friendliness is achieved.

Description

technical field [0001] The invention relates to metallurgical equipment, in particular to a tunnel kiln used for the pretreatment of metallurgical charge blocks. Background technique [0002] At present, the traditional tunnel kiln does not have strict requirements on sealing, especially when the kiln car enters and exits the tunnel kiln. Therefore, the main problems existing in the existing tunnel kiln are high energy consumption and high cost. At the same time, the existing tunnel kiln needs to be equipped with a cooling zone, and the production capacity of a single kiln is low. Contents of the invention [0003] The object of the present invention is to provide a tunnel kiln for smelting, which can be used to dry, preheat and roast the furnace material block to facilitate subsequent metal smelting, realize energy saving and emission reduction, and improve production efficiency at the same time. [0004] The invention provides a tunnel kiln for smelting, which includes ...
