Abstract
The utility model discloses a hearth supporting device of rotary hearth furnace used in coal-based direct reduced iron novel technology. The hearth of the rotary hearth furnace of the utility model is composed of an upper furnace plate and a lower furnace plate, wherein, forged steel back-up rolls are uniformly fixed on the outer circumference of the lower furnace plate; a permanent runner is provided at the lower end of each forged steel back-up roll; the support runner is arranged in the support track, and the support track is mounted on the concrete foundation. The utility model is suitable for large-sized rotary hearth furnace apparatus (apparatus with megaton annual capacity), providing stable support for placing a great deal raw materials in the rotary hearth furnace, in order to achieve high productivity.
Description
Technical field
The utility model relates to coal-based direct reduction iron production equipment field, more particularly, relates to a kind of bracing or strutting arrangement that is used for the rotary hearth furnace furnace bottom.
Background technology
Along with the continuous development of international steel industry and the quick raising of production capacity, opposite scarcity of coking coal resource and improving constantly of environmental requirement have also brought huge pressure for steel sustainable development.
Steel and iron industry adapts to the environmental protection requirement that improves day by day in order to break away from the yoke of coking coal resource shortage to the steel and iron industry development, realizes energy-saving and cost-reducing; improve the steel products structure; realize the comprehensive utilization of resource, under this environment, the coal-based direct reduction iron technology is also promoted development fast.The production scale of coal-based direct reduction iron new technology is less at present, and the maximum in the world at present rotary hearth furnace coal base reduction iron U.S. IRON of power Inland Steel annual production is 500,000 tons, and existing equipment has restricted output.
The utility model content
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, and a kind of rotary hearth furnace furnace bottom bracing or strutting arrangement that is used for the coal-based direct reduction iron new technology is provided.
The utility model rotary hearth furnace furnace bottom bracing or strutting arrangement is achieved by following technical proposals, and the rotary hearth furnace furnace bottom is made up of upper stone or metal plate for standing on a stove as a precaution against fire and lower stone or metal plate for standing on a stove as a precaution against fire, it is characterized in that, described lower stone or metal plate for standing on a stove as a precaution against fire bottom surface excircle is fixing forged steel backing roll evenly; Each forged steel backing roll lower end fixed support runner; Described support runner is arranged in the supporting track, and supporting track is installed on the concrete foundation.
The utility model is applicable to large-scale rotary hearth furnace equipment (annual production megaton equipment), provides firm support for placing a large amount of raw materials in the rotary hearth furnace, thereby realizes high production capacity.
Description of drawings
Fig. 1 the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the rotary hearth furnace furnace bottom is made up of upper stone or metal plate for standing on a stove as a precaution against fire and lower stone or metal plate for standing on a stove as a precaution against fire, and described lower stone or metal plate for standing on a stove as a precaution against fire bottom surface excircle is fixing forged steel backing roll 1 evenly; Each forged steel backing roll lower end fixed support runner 2; Described support runner is arranged in the supporting track 3, and supporting track is installed on the concrete foundation 4.
Rotary hearth furnace in use lower stone or metal plate for standing on a stove as a precaution against fire is subjected to drive rotation, and backing roll rotates with supporting in the supporting track of runner on concrete foundation simultaneously, for whole furnace bottom is done an effectively overfill protection.
Embodiment recited above is described the utility model preferred implementation; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; common engineers and technicians make the technical solution of the utility model in this area various distortion and improvement all should belong to protection domain of the present utility model.
