Abstract

The invention relates to a heating furnace comprising a furnace body (1), a furnace door, a hearth (2) and a furnace door sealing structure. The furnace body (1) is provided with a heat storage chamber (4), separating layers (5) are arranged in the heat storage chamber (4), the furnace door is compressed and sealed through the lever principle, the moving distance is limited with limit bolts (11 and 3), and the furnace door sealing structure is provided with two sealing structures. The heating furnace is uniform in workpiece heating, convenient for smoke exhaust, good in sealability of the furnace door and long in service life.

Description

technical field [0001] The invention relates to a heating furnace. It belongs to the technical field of heating furnace equipment. Background technique [0002] In the metallurgical industry, a heating furnace is a device (industrial furnace) that heats materials or workpieces (usually metals) to the temperature of rolling to forging. [0003] Heating furnaces are used in petroleum, chemical, metallurgy, machinery, heat treatment, surface treatment, building materials, electronics, materials, light industry, daily chemicals, pharmaceuticals and many other industries. [0004] The existing heating furnace has the following problems: [0005] 1) The flue gas channel of the existing regenerative heating furnace is in the upper part of the furnace. Since there is no circulation channel, when the workpiece is heated in the furnace, the temperature of the workpiece located in the upper part of the furnace is high, and the temperature of the workpiece located in the lower part of...
