The utility model discloses a movable coke oven heat insulating wall, including pushing ram, pushing ram, vertical support and swash bracket, vertical support top and swash bracket lower extreme are articulated, the inboard fixed mounting rock wool quilt of vertical support and swash bracket, vertical support lower extreme installation end boots, the inboard horizontal fixed mounting pushing ram of pushing ram, the pushing ram is terminal and the vertical support outside is articulated, it is indoor that the pushing ram is used for pushing the coke oven carbomorphism with vertical support and swash bracket level, when carbomorphism room brickwork overhauld, the support that uses pushing ram and pushing ram will install the rock wool quilt pushed the indoor side of carbomorphism, and the rock wool can be played adiabatic effect at square one -tenths space for maintenance thereafter on the one hand, reduction intensity of labour, and the easy access, one side in addition, the utility model provides an it is fixed in carbomorphism room stove frame top that the rock wool is target in place the after -fixing by outside part of extending in the propulsion, and the tedge can be followed to the raw coke oven gas that is formed by the red coke of inboard the rock wool is derived, avoids causing the waste of raw coke oven gas.
