specific Embodiment approach

[0014] Heat treatment furnace of the present invention is used lightweight sealing curtain, and its preferred embodiment is:

[0015] It includes stainless steel braided mesh and reinforced heat-resistant steel fiber cloth that are pressed together, and the stainless steel braided mesh and reinforced heat-resistant steel fiber cloth are folded toward one side of the stainless steel braided mesh and hung on the airtight curtain hanging device .

[0016] After the stainless steel woven mesh and the reinforced heat-resistant steel fiber cloth are folded in half, the interior is filled with a heat-insulating fiber blanket.

[0017] A rectangular hollow section steel is provided below the airtight curtain hanging device, and the stainless steel braided mesh and reinforced heat-resistant steel fiber cloth are folded in half to clamp the rectangular hollow section steel.

[0018] The thickness of the reinforced heat-resistant steel fiber cloth is 3mm, the stainless steel braided mes...

specific Embodiment

[0022] Such as figure 1 As shown, the stainless steel woven mesh and fiber silk cloth are folded in half according to the required size, and fixed with rectangular hollow steel under the hanging device. And the hanging device is identical in principle with the existing airtight curtain hanging device.

[0023] Features and advantages of the present invention are:

[0024] 1. Greatly reduce the weight of the existing sealing curtain, which is only 1 / 3 of the weight of the existing sealing curtain.

[0025] 2. The flexibility far exceeds that of the existing sealing curtain, which reduces the scratches on the heat-treated steel plate.

[0026] 3. The sealing and heat preservation performance is higher than that of the existing sealing curtain.

[0027] 3. Simple structure, convenient installation, operation and maintenance.

Abstract

The invention discloses a light sealing curtain used for a thermal treatment furnace. The light sealing curtain comprises a stainless steel woven mesh and enhancement heat-resistant steel wire fire cloth, wherein the stainless steel woven mesh and the enhancement heat-resistant steel wire fire cloth are laminated together. The stainless steel woven mesh and the enhancement heat-resistant steel wire fire cloth are hung on a sealing curtain hoisting device after being folded in half towards one face of the stainless steel woven mesh. The stainless steel woven mesh and the enhancement heat-resistant steel wire fire cloth are filled with a thermal insulation fiber blanket after being folded in half. A rectangular hollow section is arranged below the sealing curtain hoisting device and is clamped after the stainless steel woven mesh and the enhancement heat-resistant steel wire fire cloth are folded in half. The heat preservation and thermal insulation effects are very good, manufacture and maintenance expenses are also greatly reduced, and the light sealing curtain is easier to manufacture compared with an existing sealing curtain.

Description

technical field [0001] The invention relates to a sealing device for a heat treatment furnace, in particular to a lightweight sealing curtain for a heat treatment furnace. Background technique [0002] In the metallurgical heat treatment furnace, due to the heat treatment process, the requirements for the atmosphere in the furnace are very strict. Therefore, in addition to setting a sealed furnace door at the charging and discharging end of the heat treatment furnace, a sealing curtain is also installed at the charging and discharging section to prevent protection in the furnace. The atmosphere overflows; at the same time, it is also necessary to consider that the sealing curtain cannot cause slip marks on the steel plate when the steel plate is put into the furnace and out of the furnace, which will affect the product quality; and consider the service life at high temperature and the convenience of maintenance and repair. [0003] At present, most of the heat treatment furn...
