Abstract

The invention discloses a rotary kiln for josephinite reduction and a manufacturing method thereof. The rotary kiln for josephinite reduction comprises a cylinder and a driving support device, wherein the cylinder is provided with a sprue gate, a support frame is arranged in the cylinder, and a refractory material is poured between the support frame and the cylinder. When the rotary kiln is manufactured, the supporting frame is installed in the cylinder body, and the refractory material is poured between the supporting frame and the cylinder body from the sprue gate. The supporting frame is arranged to support a refractory material lining, so that the refractory material can be poured between the supporting frame and the cylinder body, compared with the mode that the refractory material is smeared or built in the cylinder body, the supporting frame is high in refractory material pouring efficiency and good in stability, cracks cannot occur on the surface of the refractory material, so that the service life of the refractory material is prolonged.

Description

technical field [0001] The invention relates to the technical field of nickel-iron ore production, in particular to a rotary kiln for nickel-iron ore reduction and a manufacturing method thereof. Background technique [0002] At present, the more advanced domestic technology of using lateritic ferronickel is the rotary kiln pre-reduction-electric furnace smelting technology. The secondary process needs to be smelted under high-temperature melting conditions. The processing capacity of a single furnace is limited, energy consumption is large, and production costs are high. In order to increase production, facilitate the expansion of production and limit costs, a technology of direct reduction of nickel-iron ore using a rotary kiln has been developed. [0003] However, in the prior art, due to the high internal temperature of the rotary kiln, it is often used in conjunction with the fireproof material lining, but the existing fireproof material lining is generally directly app...
