Problems solved by technology

[0003] The ball part of the slag-stop cone generally adopts the internal counterweight iron core and the counterweight method of wrapping the refractory material on the outside. Due to the high temperature of the molten steel, the slag-stopping cone melts and damages the contact between the rebar and the molten steel, which seriously affects the slag-stopping function of the slag-stopping cone. At the same time, the exposed rebar is easy to scratch the packaging bag during transportation. , may cause scratches when workers carry

Embodiment 1

[0016] Embodiment 1: as figure 1 As shown, a schematic diagram of a converter slag-stopping cone, including a sphere 2, a threaded steel 1 penetrating the sphere, and a rod body castable 3 bonded to the surface of the threaded steel 1, the tail end of the threaded steel has a thread 5, and the tail end of the rod body castable An arc-shaped end 4 is provided.

Embodiment 2

[0017] Example 2: figure 2 for figure 1 On the basis of Example 1, there is a thread opening 4.1 in the center of the end 4, which wraps the rod body casting material layer 4.3, and the rod body casting material layer 3 is wrapped with a chrome corundum fire clay layer 4.2, and the thread opening 4.1 is connected with the screw thread 5 of the rebar, the outer surface of the thread opening 4.1 is covered with triangular barbs, the tail of the rebar 1 is provided with a conical head 1.1, the head 1.1 extends out of the thread opening 4.1, and the castable material layer 4.3 of the rod body The direct contact with the plug 1.1 further strengthens the overall tightness of the entire converter slag retaining cone. The chrome corundum fire clay layer 4.2 protects the castable 3 of the rod body from falling off from the bottom when the slag retaining cone is inserted into the molten steel, and keeps the inside of the end 4 stable when the molten steel or steel slag touches. The th...

Abstract

The invention discloses a converter slag stop cone. The converter slag stop cone comprises a sphere, thread steel penetrating through the sphere and a rod body castable bonded on the surface of the thread steel; a thread is arranged at the tail end of the thread steel; an arc end is arranged at the tail end of the rod body castable; a screw thread is arranged in the end; the end is wrapped by a refractory material; and the screw thread and the thread at the tail part of the thread steel are fastened. Through the tail wrapping structure, the slag stop cone is convenient to smoothly reach a steel outlet, so that quick melting damage of the thread steel is prevented; and meanwhile, through the arc shape of the tail end of the thread steel, the thread steel is effectively prevented from puncturing a packing bag in the transportation process, and meanwhile, the scratch of workers during carrying is prevented.

Description

technical field [0001] The invention is a slag retaining cone used for slag retaining during converter smelting and tapping, and is an improvement on the tail structure of the slag retaining cone. Background technique [0002] The converter slag stop cone is composed of a sphere part and a rod part. It is used as a functional refractory material to prevent slag from flowing from the tap hole to the ladle in the later stage of converter steelmaking and tapping. It is inserted into the tap hole. [0003] The ball part of the slag-stop cone generally adopts the internal counterweight iron core and the counterweight method of wrapping the refractory material on the outside. Due to the high temperature of the molten steel, the slag-stopping cone melts and damages the contact between the rebar and the molten steel, which seriously affects the slag-stopping function of the slag-stopping cone. At the same time, the exposed rebar is easy to scratch the packaging bag during transport...
