Converter sliding plate slag-stopping gas-cooled oil cylinder

The utility model discloses a converter sliding plate slag-stopping gas-cooled oil cylinder. The oil cylinder is arranged in a cooling jacket (3); a cavity is formed between the oil cylinder and the cooling jacket (3), and comprises a cylinder block (6) and a piston rod (1) arranged in the cylinder block (6); a gas inlet (7) and a gas outlet (5) are formed on one side of the cooling jacket (3), while an oil inlet (4) and an oil outlet (2) are formed on the other side of the cooling jacket (3); the gas inlet (7) and the gas outlet (5) are connected with the cavity; and the oil inlet (4) and the oil outlet (2) are connected with the cylinder block (6). According to the technical scheme, the converter sliding plate slag-stopping gas-cooled oil cylinder is cooled by use of an air cylinder, and therefore, the existing equipment is remained and the cost is saved, and meanwhile, the water leakage of a water-cooled oil cylinder is also avoided and the potential safety hazards are eliminated; the gas discharged by the gas-cooled oil cylinder also serves as a purging and cooling medium for a sliding plate mechanism; the medium is used in series and used for two purposes; and as a result, multiple purposes are achieved and the goals of saving energy and reducing consumption are achieved.
