Metallurgical cranes operate by longitudinal movement along the factory track direction, lateral movement of the trolley, and lifting movement of the hook. They are applicable to metal smelting workshops and are special cranes for lifting molten metals that comply with the standards of JB/T7688.1-95 and JB/T7688.15-95. The application of metallurgical cranes is generally suitable for an ambient temperature ranging from -10°C to +50°C. The relative humidity does not exceed 50% at a temperature of 40°C, and the radiant temperature of the molten metal lifted on the forging hook and plate hook does not exceed 300°C. Working levels: A7 and A8 are used in relatively busy metallurgical foundry workshops.
Metallurgical cranes are mainly special cranes applicable to metal smelting, rolling and hot processing, etc. These include open-hearth charging bridge cranes, ground charging cranes, hopper cranes, ingot stripping cranes, full-mold cranes, cover uncovering cranes, clamp cranes, slab turnover cranes, forging cranes, charging and discharging cranes for heating furnaces, hopper – electromagnetic cranes, and hopper – grab cranes.
The YZ type casting bridge crane adopts a double beam and single trolley structure, mainly composed of a bridge, trolley, hook beam, crane operation and electrical parts. The main hook lifting device is a fixed spacing hook beam, used to lift the molten steel ladle, and the auxiliary hook is used to cooperate with the main hook to pour molten steel, steel slag, and other auxiliary lifting operations.
In order to reduce the thermal radiation of molten steel on metal structural components, insulation panels are installed at the bottom of the main beam along the span direction.The operating mechanism of the crane adopts a four corner drive form.The crane is equipped with a matching electronic scale, and there are obvious display devices in the driver's cab and on the bridge frame
The steel ladle double hook lifting device is mainly used for the lifting of intermediate tanks, molten iron tanks, molten steel ladles, and steel ladles in various steel plants. Its structure is simple, operation is convenient, and it is safe and reliable. The beam body is made of high-quality low-carbon alloy steel, with high strength and high temperature resistance. The hook body is spliced and riveted with steel plates, and has high strength and flexibility. At the same time, the hook body can rotate freely in front, back, left, and right, making it easy to hook.
QDY electric double beam bridge metallurgical crane is mainly used for lifting molten metal in metallurgical, casting and other places. The working level of the whole machine is A7, and an insulation layer device is added at the bottom of the main beam. The assembly and testing of the crane comply with the Quality Supervision, Inspection and Quarantine General Administration's document No. 375 [2007]. Other places for lifting molten non-metallic materials and lifting hot solid metals can also refer to the selection. (Note: H0 in the following figure represents the height added to the buffer of the large vehicle. H0 ≤ 250)
Environmental conditions:
The power supply of the crane is three-phase AC, with a rated frequency of 50Hz and a rated voltage of 380V;
The working environment temperature is -10~+60 ℃;
The relative humidity shall not exceed 50% at a temperature of+40 ℃;
The steel billet clamp adopts the lever principle, which can achieve the clamping of square billets without external assistance. The clamping is reliable, the action is flexible, and the lifting is safe and reliable. The actuator is made of high-strength and wear-resistant alloy steel, with flexible action and long service life. The structure of square billet lifting pliers is divided into fixed and adjustable (height h is infinitely adjustable) to adapt to the lifting of square billets of different specifications and layers. The connection form with the customer's overhead crane can be designed according to the actual situation. The steel billet clamp mainly consists of seven parts: lifting beam, connecting rod, opening and closing mechanism, synchronizer, clamp arm, support plate, and clamp tooth.
The annual output is more than 900,00 units, with more than 100 sets of advanced equipment, and the full product line automation rate reaches 80% .
