Abstract

The utility model belongs to the design of a novel smelting casting ladle. The utility model is additionally provided with a pit and one or a plurality of grooves on a casting ladle refractory lining. By the deformation, solid additions are rushed out by fluid in novel smelting casting ladle or are floated on a liquid level or are exploded, which is avoided. The novel smelting casting ladle is mainly used for solving the problem that zinc or zinc additions needs to be added into cast iron or cast steel for removing gas or producing nutritious iron cooking pots, which is difficult to implement in an ordinary ladle. The utility model can also be used for adding gas removal agent or modifier or scouring agent, etc. in other non-ferrous metal metallurgy.

Description

Novel smelting casting ladle

The utility model belongs to the design of novel smelting casting ladle.

In cast iron or cast steel, for degasification or production nutritive and healthy cast iron pot, need to add zinc or zinc-base additive, the substrate surface fire clay is a basin shape in common, when this bag zincification or zinc-base additive, therefore, the material that adds splashes with current or float on the molten iron surface or because of the very big instantaneous explosion of fusing point contrast because at the bottom of the bag of basin shape, going out of molten iron stream is a slip-stream shape.

The purpose of this utility model is a kind of casting ladle that is used for iron or molten steel adding zinc-base degasifier or nutritional agents of design, the liner fire clay of this casting ladle bottom has 1 pit, and the hole around be 1 or several grooves, what this design can success reaches degassing purpose, and can evenly add nutritional agents.

Casting ladle of the present utility model is: other parts such as the outer steel shell of bag all need not change, only normal packet bottom surface refractory liner shape is once changed, its smooth bowl shape center is increased by 1 pit, the bottom of pit still is slick and sly little basin shape, and the hole around be 1 or several grooves, bottom portion of groove is slick and sly parabolical.The size of pit and groove or convex-concave degree should be corresponding in the volume of the addition of the iron that uses or molten steel tapping temperature, additive and composition, bag, otherwise impact effect.

Embodiment of the present utility model, be described below in conjunction with the accompanying drawings: accompanying drawing 1 is the schematic diagram of novel smelting casting ladle, outer steel shell among the figure (1) is shaped as the general narrow truncated cone-shaped in the wide end of mouth, refractory liner (2) has 1 pit and 1 groove in bottom centre, the bottom in hole is slick and sly little basin shape, bottom portion of groove is slick and sly parabolical, in use, additive is put into groove, impouring iron or molten steel are gone into bag again, increase the pit groove newly, change iron or steel flow impact direction, and evenly carry additive secretly along with iron or molten steel are gone into bag, additive begins to react gradually and evenly disperses in bag, the impulsive force that additive reaction produces makes fluid form the rational flow direction, reaches from mixing effect, because additive is dispersed in bag end recess, both avoided fusing to gather blast, also avoided owing to go into iron clad or molten steel instant impact, and made bag end additive go out the outer or floating iron of bag or molten steel surface and scaling loss.Accomplish the end in view.

Claims (1)

1. novel smelting casting ladle, outer steel shell (1) are shaped as the general narrow truncated cone-shaped in the wide end of mouth, it is characterized in that refractory liner (2) is 1 pit and 1 groove, and the bottom of pit is slick and sly little basin shape, and bottom portion of groove is slick and sly parabolical around it.
