Description
Technical Field
The utility model relates to an industrial furnace field specifically is a walking beam bottom heating furnace of increasing the thermal efficiency.
Background
The walking-beam bottom type heating furnace is a furnace type commonly used in industrial furnaces, and conveys blanks from an inlet to an outlet through a walking mechanism, and the blanks are heated in a hearth in the conveying process, so that the existing walking-beam bottom type heating furnace has the following problems: 1. referring to fig. 2, the furnace top structure is a combined furnace top of refractory castable 1, hanging bricks 2 and ceramic fiber blankets 3, the refractory castable 1 is hung by a hanging hook 4, and the ceramic fiber blankets are used for external heat preservation, the furnace top of the structure has higher heat conductivity coefficient and lower heat preservation performance, and is integrated with a furnace body, and a part of the furnace top needs to be broken due to narrow operation space during maintenance, and is repaired after the maintenance is finished, so that the maintenance time is increased, and the production efficiency is reduced; 2. have about 30 mm's clearance between activity stove bottom and the fixed stove bottom and provide the thermal expansion space, in water in the water sealed tank is evaporated by high temperature radiation and is produced steam and can get into furnace from the clearance, on the one hand produces harmful effects to the blank, and on the other hand can take away the heat in some furnace, has reduced heating efficiency.
Disclosure of Invention
The utility model aims at providing a stepping bottom type heating furnace for improving the heat efficiency in order to solve the problem that the heating efficiency of the existing stepping bottom type heating furnace is low.
The utility model has the following concrete scheme: a stepping bottom type heating furnace for improving heat efficiency comprises a furnace body, wherein a stepping mechanism is arranged in the middle of the bottom of the furnace body, a movable furnace bottom is arranged at the top of the stepping mechanism, gaps are reserved between two sides of the movable furnace bottom and a fixed furnace bottom of the furnace body, a furnace top which can be disassembled and replaced is arranged at the top of the furnace body, the furnace top comprises a steel structure support, and a plurality of ceramic fiber cotton modules are arranged at the bottom of the steel structure support; and two supporting plates are respectively arranged on two sides of the movable furnace bottom along the whole length, each supporting plate is fixedly provided with a ceramic fiber plate, and the ceramic fiber plates are filled in a gap between the movable furnace bottom and the fixed furnace bottom.
Be equipped with one deck ceramic fiber back lining blanket between steel structural support and the ceramic fiber module, the ceramic fiber module passes through stainless steel bolt anchor assembly to be fixed on steel structural support.
The lug is equipped with to steel construction support top.
The working principle of the utility model is as follows: the heat conductivity coefficient of the ceramic fiber is lower than that of the traditional refractory castable, so that the thermal insulation performance of the furnace top is improved by improving the furnace top into a conforming structure of a steel structure bracket and a ceramic fiber module, and the thermal efficiency of the furnace is improved; on the other hand, gaps on two sides of the movable furnace bottom are filled through the ceramic fiber plates, and the ceramic fiber plates have certain compressibility, so that expansion space is ensured, heat is prevented from being dissipated from the gaps, and heating efficiency of the furnace is improved.
Compared with the prior art, the utility model has the following advantage:
1. the heat preservation performance of the top-level movable furnace bottom is better, and the heat efficiency of the furnace is improved; 2. when the furnace bottom needs to be maintained, the single furnace top can be lifted and moved integrally. Repeated installation does not affect the use; 3. the influence of water vapor on the temperature of the steel billet does not exist, and the heat efficiency of the furnace is improved; 4. the ceramic fiber plate with the sealed furnace bottom is convenient to install and replace, the whole ceramic fiber plate can be replaced well about half an hour when the furnace is shut down for maintenance at each time, and the effective operation rate of the furnace is improved.
