Ramming device for lining of medium-frequency induction furnace

Abstract

The invention relates to a ramming device for the lining of a medium-frequency induction furnace. The ramming device comprises a support stretching across the electric furnace. A screw rotating on the support is arranged on the support. The lower end of the screw is fixedly connected with a round lifting platform which is arranged horizontally. A drive mechanism used for driving the screw to rotate so as to enable the lifting platform to move up and down is arranged on the support. Two or more ramming units are arranged on the lifting platforms. Each ramming unit comprises a telescopic oil cylinder arranged on the lifting platform, wherein the telescopic end of the telescopic oil cylinder is fixedly connected with an arc-shaped ramming plate, the telescopic oil cylinder is arranged on the upper surface of the lifting platform through a base plate, and the base plate is provided with kidney-shaped adjusting holes arranged in the diameter direction of the lifting platform, and locking pieces which are inserted into the corresponding adjusting holes and penetrate through the lifting platform to lock the base plate and the lifting platform. The ramming device for the lining of the medium-frequency induction furnace is simple in structure and convenient to use, manpower is greatly saved in the furnace lining manufacturing process, the production cost of the furnace lining is lowered, and application and promotion are facilitated.

Description

technical field [0001] The invention relates to a lining ramming device of an intermediate frequency induction electric furnace. Background technique [0002] In the manufacturing process of the intermediate frequency induction furnace, in order to make the electric furnace have a lining with good high temperature performance, the lining body is required to have a high density and a uniform density during the lining production stage. Therefore, it is necessary to ram the lining material to discharge the air in the lining to make it dense. The furnace lining ramming method of the transmission is manual ramming. This method has the disadvantages of high labor intensity for workers and consumes a lot of manpower. In addition, it needs to work in the furnace and the operating conditions are poor, so that the quality of the rammed furnace lining is affected by human factors. The impact is relatively large and cannot be guaranteed. Contents of the invention [0003] In view of...
