Problems solved by technology

However, since the material will have a certain thickness after being spread on the hearth, this will cause the upper layer of the material to receive more heat per unit time, while the lower layer of material is covered by the upper layer of material, accepting less heat, and the material is heated unevenly. Differences seriously affect product quality, and even generate a lot of waste

Abstract

The invention discloses a rotary hearth furnace, which comprises: an annular furnace body, a hearth, a burner and a material turning device. The furnace body defines a furnace chamber; the hearth is arranged in the furnace chamber, and the hearth rotates horizontally around the central axis of the furnace body; the burner is arranged on the furnace body; the turning The charging device includes a turning member for turning up materials on the hearth, and the turning member is arranged in the furnace cavity and above the hearth. According to the rotary hearth furnace of the embodiment of the present invention, by setting the turning member on the upper part of the hearth, the turning member can turn the material during the movement of the material, so that the upper and lower layers of materials are scattered and rearranged, and the heating device can realize the Uniform heating of materials, thereby improving the production efficiency and product quality of the rotary hearth furnace.

Description

technical field [0001] The invention relates to the field of metallurgical thermal processing equipment, in particular to a rotary hearth furnace. Background technique [0002] In the field of metallurgical thermal processing equipment, the rotary hearth furnace heating reduction device is the core equipment for processing waste solids, copper slag, aluminum slag, etc. in steel mills in the reduction smelting process. The core component of the rotary hearth furnace is a flat hearth that can be rotated and moved in a circular manner, and the outside of the hearth and the furnace roof are protected by furnace shells and refractory materials. In the process of processing, the material is laid by the material spreading machine, so that the hearth is covered with materials, and the furnace body is equipped with a gas burner heating device to heat the material spread on the hearth. Control the reducing gas in each furnace section by controlling the air-fuel ratio, and heat and re...
