Abstract
The utility model discloses the structure of a driving furnace bottom, which is used for a new technology for directly reducing iron from coal base. An upper furnace plate is provided with a fireproof material layer, the outer circle at the bottom surface of a lower furnace plate is evenly provided with supporting devices, the supporting devices comprise a forged steel supporting roller, a supporting rotating wheel and a supporting track, and the outer circle of the lower furnace plate is evenly provided with a driving device. The structure is applicable to large-scale rotary hearth furnace equipment (equipment with megaton annual output), and stably supports a mass of raw materials put in the rotary hearth furnace, thereby realizing high capacity.
Description
Technical field
The utility model relates to coal-based direct reduction iron production unit field, more particularly, relates to a kind of transmission bottom construction that is used for rotary hearth furnace.
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.
Iron And Steel 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 Iron And Steel 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 industrial scale of coal-based direct reduction iron novel process 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 transmission bottom construction that is used for the coal-based direct reduction iron novel process is provided.
The utility model transmission bottom construction, be achieved by following technical proposals, 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, on the described upper stone or metal plate for standing on a stove as a precaution against fire refractory masses is set, described lower stone or metal plate for standing on a stove as a precaution against fire bottom surface excircle evenly is provided with bracing or strutting arrangement, and described bracing or strutting arrangement comprises the forged steel supporting roll, supports runner and supporting track, and lower stone or metal plate for standing on a stove as a precaution against fire bottom surface excircle is the forged steel supporting roll fixedly; Each forged steel supporting roll lower end fixed support runner; Described support runner is arranged in the supporting track, supporting track is installed on the concrete foundation, described lower stone or metal plate for standing on a stove as a precaution against fire excircle evenly is provided with drive unit, described drive unit is made up of oil motor, step-down gear, transmitting gear, pin gear, the pin gear is changeing beneath stone or metal plate for standing a stove on as a precaution against fire excircle with Bolt Connection, described oil motor connects step-down gear and transmitting gear successively, transmitting gear and pin toothing.
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; Place raw material on the upper stone or metal plate for standing on a stove as a precaution against fire refractory masses, heat resisting temperature can reach about 1000 ℃, can ensure under hot conditions the support to raw material.

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 14 and lower stone or metal plate for standing on a stove as a precaution against fire 15, refractory masses 16 is set on the described upper stone or metal plate for standing on a stove as a precaution against fire, described lower stone or metal plate for standing on a stove as a precaution against fire bottom surface excircle evenly is provided with bracing or strutting arrangement 12, described lower stone or metal plate for standing on a stove as a precaution against fire excircle evenly is provided with drive unit 11, as shown in Figure 2, bracing or strutting arrangement comprises forged steel supporting roll 1, supports runner 2 and supporting track 3, and lower stone or metal plate for standing on a stove as a precaution against fire bottom surface excircle is the forged steel supporting roll fixedly; Each forged steel supporting roll lower end fixed support runner; Described support runner is arranged in the supporting track, and supporting track is installed on the concrete foundation 4; As shown in Figure 3, described drive unit is made up of oil motor 31, step-down gear 32, transmitting gear 33, pin gear 34, the pin gear is changeing beneath stone or metal plate for standing a stove on as a precaution against fire excircle with Bolt Connection, and described oil motor connects step-down gear and transmitting gear successively, transmitting gear and pin toothing.
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 supporting 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 engineering technical personnel 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.
