         電阻爐的日常修理維護

        一、圍繞爐體的修理
        1、 Repair around furnace body
        磚砌爐常見故障主要是加熱體和砌體的局部修理;鹽浴爐常見故障是漏鹽和電腐蝕;真空爐常見故障是加熱體損壞和爐體泄漏。針對常見故障現象和原因,應注意砌筑爐體時的方法、結構和選材。
        The common faults of brick furnace are mainly the local repair of heating body and masonry; The common faults of salt bath furnace are salt leakage and electric corrosion; The common faults of vacuum furnace are heating body damage and furnace body leakage. In view of common fault phenomena and causes, attention should be paid to the method, structure and material selection when building the furnace body.


        1.整體筑爐
        1. Integral furnace building
        普通熱處理電阻爐整體筑爐時,磚砌爐的原砌擱加熱體高鋁擱磚尺寸處應留下插擱磚的槽。日常的修理主要是換爐絲擱磚和爐絲。
        When the general heat treatment resistance furnace is built as a whole, a slot for inserting bricks shall be left at the size of the high aluminum brick of the original heating body of the brick furnace. Daily repair is mainly to replace furnace wire, put bricks and furnace wire.
        對鹽浴爐故障――漏鹽和電腐蝕,采用澆筑法解決爐體漏鹽;針對電動機易腐蝕,將爐體澆筑成兩體,即電單獨澆筑成一個階梯形的塊,電腐蝕后,只拆除需更換電部分。
        For the salt bath furnace fault - salt leakage and electric corrosion, the pouring method is used to solve the salt leakage of the furnace body; In view of the easy corrosion of the motor, the furnace body is poured into two parts, that is, the electric part is poured into a stepped block separately. After the electric corrosion, only the electric part needs to be removed and replaced.
        2.磚砌爐方式
        2. Brick furnace mode
        (1)采取針對性修理,注意較大磚砌爐的后墻、側墻、爐門拱、爐膛拱頂等彼此之間不要互相咬合壓死,這樣局部損壞時不用扒爐整體重砌,可對以上幾部分單獨修理。
        (1) Targeted repair shall be adopted, and attention shall be paid to the rear wall, side wall, furnace door arch, furnace arch top, etc. of the larger brick furnace. They shall not bite and crush each other. In this way, in case of local damage, there is no need to build the furnace as a whole, and the above parts can be repaired separately.
        如爐子拱腳不一定要支在側墻上,可支在爐子兩側鋼結構的拱腳梁上(見圖1),使爐墻不受拱頂的力,對爐墻和拱頂都有好處。但考慮拱腳梁的受熱膨脹,要留有空隙。砌拱頂磚時,從兩側拱腳同時向對稱砌筑。拱頂鎖磚不得砍削,鎖磚應準確地按拱頂的中線進行分布。
        For example, the arch foot of the furnace does not have to be supported on the side wall, but can be supported on the arch foot beam of the steel structure on both sides of the furnace (see Fig. 1), so that the furnace wall is not subject to the force of the vault, which is good for both the furnace wall and the vault. However, considering the thermal expansion of arch foot beam, a gap shall be reserved. When laying vault bricks, the arch feet on both sides shall be laid symmetrically at the same time. The lock bricks of the arch crown shall not be cut, and the lock bricks shall be accurately distributed according to the center line of the arch crown.
