A box type heating furnace

Abstract

The invention discloses a box-type heating furnace in the technical field of heating equipment. The box-type heating furnace comprises a furnace shell. A steel plate is arranged on the outer wall of the furnace shell. H-shaped steel plate bodies are evenly arranged on the inner wall of the steel plate. The left wall and the right wall of the furnace shell are each provided with a pipe orifice. The outer wall of each pipe orifice is provided with a connection flange. A furnace liner is arranged in an inner cavity of the furnace shell, and an anchor piece is arranged between the furnace liner and the furnace shell. Due to the fact that the steel plate is arranged on the outer wall of the furnace shell, and the H-shaped steel plate bodies are evenly arranged on the inner wall of the steel plate, the structure strength is improved, and the temperature of the furnace shell is greatly reduced; and the left end and the right end of a furnace gate are each provided with a furnace gate elevating device, each furnace gate elevating device comprises a gantry framework, the top of each gantry framework is provided with a drive motor, a chain wheel is arranged at the right end of each drive motor, a transmission chain is arranged on the outer wall of each chain wheel, the bottom of each transmission chain is fixedly connected with the outer wall of the furnace gate, thus, the furnace gate can be opened and closed electrically as needed, and the trouble of the manual mode is omitted.

Description

technical field [0001] The invention relates to the technical field of heating equipment, in particular to a box-type heating furnace. Background technique [0002] In the production process of alloy products such as steel plates and large container heads, the heat treatment step is an essential key step, which has a great impact on the performance of the product. At present, the heating equipment often used in heat treatment is a box-type heating furnace. At present The disadvantage of the box-type heating furnace is that the temperature in the furnace is not uniform, and the upper part is higher than the lower part. Therefore, when heating the workpiece, the heating temperature is not uniform. Prolonging the heating time and holding time not only wastes energy and increases production costs, but also reduces production efficiency and poor economic benefits. For example, Chinese patent application number 201220576335.4 is a box-type heating furnace, which includes furnace w...

Problems solved by technology

[0003] The purpose of the present invention is to provide a box-type heating furnace to solve the disadvantages of the current box-type heating furnace proposed in the above-mentioned background technology that the temperature in the furnace is not uniform, and the top is high and the bottom is low. Therefore, when heating workpieces, the heating temperature If you want to make the heating temperature of the heating workpiece such as steel plate uniform during production, you need to prolong the heating time and holding time, which not only wastes energy, increases production costs, but also reduces production efficiency and poor economic benefits. question
