Opening iron mouth machine is a common equipment in ironmaking plant. Its function is to open the iron mouth of blast furnace and realize modern blast furnace smelting. Components: The structure of iron opening machine is mainly composed of rotary part and drilling part. The drilling part mainly consists of the thrust and percussion part, which is carried from the parking position to the working position by the rotary part, and then quickly returned to the parking position after opening the iron hole. The reliability and performance of opening machine are directly related to the production efficiency of blast furnace ironmaking.
Structure Form
Opening machine can be divided into 6 kinds according to its structure: hanging type, frame type, inclined seat type, elevated column type, low seat type, folding type; According to its drilling principle, it can be divided into 4 kinds: single impact type, single drilling type, combined impact drilling type, combined forward and recoil drilling type; According to the power source, it can be divided into 6 kinds: electric, pneumatic, hydraulic, electric combination, gas-liquid combination, electro-hydraulic combination.
Nowadays, there are many types of opening machine used in blast furnace at home and abroad. From the transmission form can be divided into electric opening iron mouth machine, pneumatic opening iron mouth machine, gas-liquid compound drive opening iron mouth machine; From the way of installation can be divided into hanging opening machine, floor opening machine. Floor type pneumatic and hydraulic compound drive iron opening machine is most widely used in large, medium and small blast furnaces in China, followed by suspension full pneumatic type and floor type full hydraulic type. The common structural characteristics of these kinds of typical opening machine are with guide rail beam and feeding mechanism, the drill along a certain Angle of the inclined track, the opening of the iron hole is the same as the Angle of the round hole, the drill has punching function. Application: Opening machine is widely used in industry, iron and steel, metallurgy, and other industries.
