Multifunctional furnace door for heating furnace and using method thereof

Abstract

The invention discloses a multifunctional furnace door for a heating furnace and a use method of the multifunctional furnace door and belongs to the field of heating furnace manufacture. With the adoption of the multifunctional furnace door, demands of bent pipes or plate workpieces and processes can be met simultaneously through an ordinary heating furnace. The multifunctional furnace door structurally comprises a tool panel 1, lifting lugs 2, furnace door outer support frames 3, a support panel 4, support side plates 5, inner support cross plates 6, inner support vertical plates 7, furnace door support plates 8, furnace door support ribbed plate 9 and the like; the multifunctional furnace door for the heating furnace is mounted in front of an original furnace door of the heating furnace and tightly pressed by a top device for a cylinder of the original furnace door; a slit type notch in the tool panel facilitates access of a to-be-heated part of a workpiece, and opening and closing of the whole furnace door are not required. The multifunctional furnace door has the benefits that the function of the original heating furnace is greatly increased, the number of furnaces is reduced, the production cost is reduced, the use ratio of a furnace chamber is increased, the operation is simple, the mounting is convenient, use of the original furnace door is not affected, and the structure of the original heating furnace is not damaged.

Description

[0001] Technical field [0002] The invention belongs to the field of heating furnace kiln manufacturing. Background technique [0003] In the machinery manufacturing and processing industry, it is often necessary to locally heat form the workpiece or perform thermal processing to improve material properties. Among them, the U-shaped heat exchange tube is an important component in the heat exchanger and plays a particularly important role in heat exchange. Its material is mostly stainless steel. Generally, due to the needs of the medium, the bent part must be subjected to local solution heat treatment after it is formed; for some engineering bent pipe fittings, it also needs to be heated in a heating furnace and then bent. [0004] For large thick plates before being rolled by a three-roller plate rolling machine, due to the limitation of the plate rolling machine, it is generally necessary to partially pre-bend both ends of the plate in a heating furnace to achieve the effec...

Problems solved by technology

[0004] For large and thick plates before being rolled by a three-roller plate rolling machine, due to the limitation of the plate rolling machine, it is generally necessary to pre-bend both ends of the plate in a heating furnace to achieve the effect of rolling; usually, this type of heating is done in It is carried out on different special-purpose heating equipment, the equipment purchase cost is relatively high, and the specificity is strong, but the utilization rate is low, and the kiln equipment is idle for a long time, causing a lot of waste

[0005] When dealing with the solution heat treatment of U-shaped tubes and the pre-bending of plates at medium temperature, if ordinary heating furnaces are used, due to the shape limitation of the furnace door of the equipment, the opening area of ​​the furnace door is too large, resulting in serious heat loss in the furnace and damage to the furnace door. certain destruction
