Technical Field

The application relates to the technical field of industrial furnaces, in particular to a flue flashboard prefabricated part for furnace pressure regulation of an industrial furnace.

Background

With the continuous development of the aluminum processing industry, the requirements on the thermal efficiency and the energy consumption of aluminum processing equipment are higher and higher. The furnace pressure control of an aluminum smelting furnace is very important and is directly related to the working pressure in the furnace. The pressure is too high, influences safe in utilization and product quality, and the pressure is low excessively to cause the burning insufficient, and the energy resource consumption increases, causes the energy waste. The adjustment of the hearth pressure is generally to control the smoke discharge amount through the opening and closing of a flue shutter. The flue dampers are frequently operated during the operation of the furnace and are constantly in a constantly adjusted state. The service temperature is high, and frequent cold and hot alternation, has proposed very high requirement to the life of flashboard.

Generally speaking, through the inside circulated air that leads to of flashboard steel structure, steel construction surface pouring refractory material's mode improves flashboard steel structure life under the high temperature. However, since the thermal expansion coefficients of the steel material and the unshaped refractory material at high temperature are not consistent, local thermal stress is generated due to the difference of expansion amount, the refractory material is cracked and peeled off, and the local falling-off is caused after long-time use, and the service life of the flashboard steel structure is influenced, it is necessary to provide a prefabricated member of the flashboard of the furnace pressure adjusting flue of the industrial furnace to solve the problems.

As shown in fig. 1 to 3, the present application provides an industrial furnace pressure regulating flue damper preform, which includes a plurality of ventilation pipes 2, the ventilation pipes 2 being made of a high temperature resistant stainless steel material, and the ventilation pipes 2 being communicated with each other. The middle part of the ventilation pipe 2 is provided with a positioning baffle plate 1, and the height of the positioning baffle plate 1 is the depth of the ventilation pipe 2 embedded into the flashboard.

On the surface of the ventilation pipe 2 and on the side of the baffle plate 1 far away from the mouth of the ventilation pipe 2, a plurality of metal anchoring pieces 3 are arranged, and each anchoring piece 3 consists of a tail seat 32, a support piece 31 and a wavy piece 33. The tailstock 32 is welded on the surface of the ventilating pipe 2, and the wavy parts 33 are wavy, so that the contact area between the wavy parts and a refractory material (namely a gate plate) can be increased, the friction force between the wavy parts and the gate plate is improved, and the connection strength between the anchoring part 3 and the gate plate is improved. The wavy member 33 and the supporting member 31 are arranged in a crossing manner, that is, the wavy member 33 and the supporting member 31 are inclined, so that the weight of the refractory material acting on the supporting member 31 can be dispersed, and the supporting effect of the whole anchor member 3 on the refractory material can be improved.

A heat shrink 7 is also fitted over the ends of the corrugated member 33, the heat shrink 7 being made of hot melt plastic.

Before the flashboard of this application is made, can weld baffle 1 to ventilation pipe 2 to reserve the height of waiting to pour, later weld the tailstock 32 of each anchor member 3 and the surface of ventilation pipe 2, overlap the thermal shrinkable sleeve 7 again at the tip of each wavy piece 33.

And then assembling a casting mold of the gate plate outside the ventilation pipe 2 and below the baffle plate 1, covering the ventilation pipe 2 below the baffle plate 1 and the anchoring piece 3 arranged on the surface of the ventilation pipe 2 by the casting mold, then, beginning to inject refractory materials into the mold, and forming a gate plate main body 4 after the refractory materials are solidified.

After the flashboard begins to use, its inside heat shrinkable sleeve 7 can be heated and melt, the ablation to with the space release that heat shrinkable sleeve 7 was originally, and form the space, this space can provide the removal space for the flashboard thermal expansion, thereby avoid refractory material (be the flashboard) and anchor assembly 3 to extrude each other because of the thermal expansion rate is inconsistent and lead to the refractory material fracture.

Meanwhile, the thickness of one side of the heat shrinkable sleeve 7 facing the axial direction of the corrugated piece 33 needs to be larger than the thickness of the periphery of the side wall of the corrugated piece, the refractory material is mainly deformed in the axial direction when being heated and expanded, and the axial deformation is also an important reason that the top end of the anchoring piece 3 is easily cracked due to the contact of the conventional refractory material and the anchoring piece 3 made of metal, and more deformation spaces are reserved in the axial direction of the corrugated piece 33, so that the situation can be reduced.
