Embodiment Construction
[0036] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0037] like Figure 1-4 As shown, the present invention provides a feed port of a rotary hearth furnace, the feed port of a rotary hearth furnace comprises a wall for defining a feed space, a water-cooled pipeline 1 arranged on the wall, and a water-cooled pipeline connected with the water-cooled pipeline respectively The water inlet pipe 3 and the water outlet pipe 4 that the two ends of 1 are connected. The material of the water-cooling pipeline 1 is generally steel. The feed port of the rotary hearth furnace proposed by the present invention reduces the temperature of the steel structure of the feed port by passing cooling water in the water-cooled pipeline...

Abstract
The invention relates to the field of rotary hearth furnace direct reduction and particularly discloses a rotary hearth furnace feeding port and a manufacturing method thereof. The rotary hearth furnace feeding port comprises a wall, a water cooling pipeline (1), a water inlet pipe (3) and a water outlet pipe (4), wherein the wall is used for limiting a feeding space; the water cooling pipeline (1) is arranged on the wall; the water inlet pipe (3) and the water outlet pipe (4) are connected with two ends of the water cooling pipeline (1) respectively. According to the rotary hearth furnace feeding port, the steel structure temperature of the feeding port is reduced through cooling water, so that the high-temperature-resistant condition of the feeding port is improved, meanwhile, the service life of the feeding port is prolonged, material losses are reduced, and continuous and stable production is guaranteed.
Description
technical field [0001] The invention relates to the field of direct reduction of a rotary hearth furnace, in particular to a feed port of a rotary hearth furnace and a manufacturing method thereof. Background technique [0002] At present, the direct reduction of the rotary hearth furnace is a hot spot in the field of metallurgy. It is favored by many manufacturers for its high reduction temperature, fast reduction speed, relatively static furnace charge and furnace bottom, and low requirements for the strength of the charge. In addition, the rotary hearth furnace direct reduction The reduction does not require a sintering process, does not use coke, is environmentally friendly, and is in line with the mainstream thinking of clean production in today's society. Therefore, in recent years, many companies have built rotary hearth furnace projects to process metallurgical waste or special minerals. [0003] Raw material processing generally adopts pelletizing or briquetting met...
