 箱式電阻爐爐襯結構的改進

箱式電阻爐能滿足多種熱處理工藝要求,是熱處理車間廣泛使用的加熱設備。小型企業、鄉鎮企業已經充分認識到對工件進行熱處理的重要性,許多熱處理企業(車間)應運而生,箱式爐成為的熱處理設備,一般多為中溫箱式電阻爐。
Box type resistance furnace can meet the requirements of various heat treatment processes and is widely used in heat treatment workshop. Small enterprises and township enterprises have fully realized the importance of heat treatment of workpieces. Many heat treatment enterprises (workshops) emerge as the times require. Box type furnace has become the most popular heat treatment equipment, generally medium temperature box type resistance furnace.
但是因工人的操作技術水平不高,裝爐、出爐時,工件經常與爐后墻、兩側爐墻磕碰,導致爐墻損壞,降低了箱式電阻爐的熱效率,熱量損失增加,甚至造成爐墻塌陷。手工操作時,稍有不甚,鉤子將容易碰撞電爐絲,造成電爐絲損壞,若保護開關損壞(有些企業甚至沒有保護開關),易出現操作人員觸電事故。
However, due to the low level of operation technology of workers, when charging and discharging, the workpiece often collides with the furnace back wall and the furnace walls on both sides, resulting in the furnace wall damage, reducing the thermal efficiency of the box resistance furnace, increasing the heat loss, and even causing the furnace wall collapse. In manual operation, if the hook is not very good, it will easily collide with the electric furnace wire, causing damage to the electric furnace wire. If the protection switch is damaged (some enterprises even do not have a protection switch), it is easy for the operator to get electric shock.


1、改進措施
1. Improvement measures
為滿足生產現狀的使用要求,延長箱式電阻爐的使用壽命,筆者主要從改進爐襯結構出發,提出以下措施:
In order to meet the use requirements of production status and extend the service life of box resistance furnace, the following measures are proposed mainly from improving the lining structure
(1)爐后墻改用重質耐火磚。按照現行的RX2系列箱式電阻爐的設計要求,爐后墻一般采用熱導率較低的輕質耐火粘土磚或漂珠磚,但因其強度低,當工件裝爐時因磕碰,易造成爐后墻的損壞。
(1) The furnace back wall is replaced by heavy refractory brick. According to the current design requirements of rx2 series box type resistance furnace, the back wall of the furnace generally adopts light refractory clay brick or floating bead brick with low thermal conductivity, but because of its low strength, it is easy to damage the back wall of the furnace due to bumping when the workpiece is loaded into the furnace.
為此改用強度較高的重質耐火粘土磚進行砌筑。為了保證箱式電阻爐的熱效率,采取的具體措施是:將爐后墻分上下兩部分砌筑,下部砌筑幾層重質耐火粘土磚(具體層數視爐膛尺寸和使用要求而定),上部仍采用輕質耐火粘土磚。
Therefore, heavy refractory clay brick with high strength is used for masonry. In order to ensure the thermal efficiency of the box resistance furnace, the specific measures are as follows: the back wall of the furnace is divided into two parts, the upper part is built with several layers of heavy refractory clay bricks (the specific number of layers depends on the size of the furnace and the use requirements), and the upper part is still built with light refractory clay bricks.
(2)將兩側爐墻底部改用1-3層重質耐火粘土磚(視工件大小而定),防止因裝卸工件不當而造成爐襯損壞。
(2) 1-3 layers of heavy refractory clay bricks (depending on the size of workpieces) are used at the bottom of furnace walls on both sides to prevent damage of furnace lining due to improper loading and unloading of workpieces.
(3)在耐火磚外側增加一層熱導率較小的硅酸鋁耐火纖維,提高爐襯的保溫性能。
(3) A layer of aluminosilicate refractory fiber with low thermal conductivity is added outside the refractory brick to improve the thermal insulation performance of the furnace lining.
2、爐襯改進后的效果
2. Effect of improved lining
(1)經過對爐襯結構的改進,在與以前相同的使用條件下,箱式電阻爐爐襯的使用壽命由原來的一年延長為近兩年。
(1) After the improvement of the lining structure, the service life of the box resistance furnace lining is extended from one year to nearly two years under the same service conditions as before.
(2)防止了操作人員觸電事故的發生。
(2) The electric shock accident of operators is prevented.
