Blast furnace slag liquid surface crust breaking device

Abstract

The invention discloses a blast furnace slag liquid face crusting breaking device, and relates to the technical field of chemical metallurgical. The problems that a crane or electric block is used forlifting a heavy hammer for slag breaking, the slag breaking position is not accurate, residue bonded on the heavy hammer cannot be cleaned, and slag breaking force is not enough are solved. Accordingto the technical scheme, the blast furnace slag liquid face crusting breaking device comprises a supporting frame, guide rods, a heavy hammer and a slag cleaning plate; a slag breaking platform is arranged on stand columns of the supporting frame, the guide rods are arranged on the slag breaking platform, a transverse connecting rod is arranged on the guide rods in a penetrating manner, a heavy hammer connecting rod and a slag breaking oil cylinder are connected to the transverse connecting rod, the slag breaking oil cylinder is used for pushing the heavy hammer to carry out slag tank liquidface crusting breaking, due to the fact that the heavy hammer is in rigid connection, pressure can be applied through the slag breaking oil cylinder, the slag breaking force can be improved, and the accurate slag breaking position is ensured. The slag cleaning plate is arranged on the slag breaking platform, and can be controlled through the slag cleaning oil cylinder, blast furnace slag remainingon the heavy hammer can be removed, and the blast furnace slag liquid face crusting breaking device is easy and convenient to operate, simple in structure and beneficial for maintaining and overhauling.

Description

technical field [0001] The invention relates to the technical field of metallurgy and chemical industry, in particular to a device for crushing crusts on the surface of hot blast furnace slag during transportation. Background technique [0002] The surface of hot blast furnace slag will solidify into a thick shell due to the temperature drop during transportation. During the process of hot blast furnace slag entering the furnace, the shell on the surface will break into large pieces of slag, which will block the passage of the furnace chute , resulting in the hot blast furnace slag not being poured into the electric furnace smoothly. Therefore, it is particularly important to carry out slag breaking treatment before pouring the hot blast furnace slag into the chute. The advantages and disadvantages of the slag breaking method and the slag breaking device determine the efficiency of the slag breaking work. [0003] At present, the main slag breaking method is usually to use...
