Description

Casting ladle with molten steel oxidation prevention function

Technical Field

The utility model relates to a five metals casting field especially relates to a water package with prevent molten steel oxidation function.

Background

The casting ladle is used for casting operation in a casting workshop, and is transported to a casting mould by a travelling crane for casting after receiving molten metal through a guide pipe in front of a furnace. The ladle suspender and the hanging ring are formed by forging, and have better cutting strength, safety and reliability than the common steel plate. Meanwhile, the volume and the material of the bag are manufactured according to the national mechanical industry standard (the standards are JB5550-91 and JB/T5771-91). The gear box adopts double worm wheel pair transmission, although the manufacturing requirement is high, the transmission is flexible and free, and the bidirectional reversibility is good.

Currently used ladles are generally not provided with a top cover. After the casting ladle receives molten metal through a guide pipe in front of the furnace, the molten steel in the casting ladle is continuously in contact with air and oxidized to form oxidation slag in the processes of vehicle transportation and casting.

When the currently used casting ladle is used for casting, the oxidation slag enters the casting mould along with the molten steel to form a casting, the forming quality of the casting is seriously influenced, and the structural strength and the hardness of the casting cannot reach the specified standard.

The body of the casting ladle used at present can rock in the front and back direction in the process of vehicle transportation, and even molten steel splashes out when the body shakes violently, so that serious potential safety hazards are generated.

Further, the rear portion of the body is vertically provided with a slide rail, the rear portion of the top cover is provided with a protruding portion, a slide rod is arranged below the protruding portion and is connected with the slide rail in a sliding mode, and the rear portion of the body is further provided with a blocking latch used for preventing the slide rod from sliding downwards.

Further, block the bolt and include that the symmetry sets up the bolt frame in the slide rail left and right sides, bolt frame and body rigid coupling, the bolt pole includes vertical section and horizontal segment, the horizontal segment is pegged graft with two bolt frames simultaneously.

Furthermore, the top cover rear part is provided with supporting parts for jacking the top cover at two sides of the protruding part.

Furthermore, the high-temperature-resistant filter screen is made of sintered magnesia.

Further, the clamping plate is hinged with the body through a hinge.

The utility model discloses following beneficial effect has:

the utility model discloses a water ladle with prevent molten steel oxidation function sets up the top cap that can move in vertical direction between body and crossbeam. When the casting ladle receives molten metal through the guide pipe in front of the furnace, operators control the top cover to ascend; when the casting ladle receives the molten metal, the top cover is controlled by operators to descend to cover the body, so that the molten steel in the casting ladle is prevented from being continuously in contact with air and oxidized to form oxide slag in the processes of vehicle transportation and casting.

The utility model discloses a set up the high temperature resistant filter screen that is used for filtering the oxidation sediment in the runner of the pouring ladle that has the function of preventing molten steel oxidation. During pouring, the oxidizing slag is blocked by the filter screen and cannot enter the casting mold to participate in casting, and the molding quality of the casting is greatly improved.

The utility model discloses a body upper portion both sides of watering packet with prevent molten steel oxidation function all set up with body articulated cardboard, the cardboard is kept away from the one end setting of body and is erected the breach that the support matches, the body sets up the stopper in the below of cardboard, when the cardboard rotates the horizontal direction, the lower surface and the stopper contact of cardboard. The both sides of the body of the casting ladle are clamped with the vertical support through the clamping plates in the process of travelling crane transportation, so that the shaking of the body in the front-back direction can be avoided, and the potential safety hazard is avoided.
