Description

Technical Field

[0001] The utility model relates to the technical field of steel metallurgy, in particular to a split slag retaining cone for a converter. Background Art

[0002] A converter is a metallurgical furnace with a rotatable furnace body used for blowing steel or blowing matte. Converter steelmaking is a steelmaking method that mainly uses liquid pig iron as raw material. The slag cone is one of the main structures of the converter and is used to control the separation of molten steel and slag. The slag cone is divided into an integrated slag cone and a split slag cone. The split slag cone is easy to transport and is widely used. In actual use, it has the advantages of simple operation, stable structure and long service life.

[0003] Prior art discloses a split-type slag-blocking cone for a converter, with publication number CN219547004U. The cone and stem are separate parts, cast from refractory material. The cone is wide at the tail and narrow at the head. Four grooves extend from the tail to the head on the cone's outer surface. A through-slot is defined in the center of the cone, with the tail end of the slot opening flaring. The stem is inserted through the opening of the cone's through-slot, forming a combined rod and cone. In this embodiment, the rod portion is cast by threaded steel and refractory material, wherein the refractory material and threaded steel are combined to form a main rod with a core and a core rod formed from a single threaded steel. The outer diameter of the main rod near the core rod is expanded outward to form an expanded diameter section. In practice, the expanded diameter section cooperates with the flared structure at the opening to achieve one-way limiting of the cone. In the above cooperation, it can be seen that the pressure on the cone will be decomposed into a radial force of a main column and an axial force of a main rod. Since the axial force and the radial force both act directly on the main rod, and even if the expanded diameter section is partially damaged, since one section can achieve limiting, the overall durability is higher, thereby making the slag stop cone more durable and having a longer service life.

[0004] In order to facilitate transportation, the above-mentioned utility model needs to store the main rod and the cone separately. During the transportation and handling of the main rod, it will touch the ground or be placed on a flat surface. The main rod is composed of a core rod and a refractory material. The refractory material wraps the core rod. At the same time, the refractory material is brittle and is easily broken when it touches the ground or is placed on a flat surface. This poses a hidden danger to the transportation and handling of the utility model.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0006] (1) Technical problems solved

[0007] In view of the deficiencies in the prior art, the present invention provides a split slag stop cone for a converter, which has the advantage of preventing the refractory material of the main rod from contacting the ground or a flat surface, thereby solving the problems in the above-mentioned background technology.

[0008] (2) Technical solution

[0009] In order to achieve the above-mentioned advantage of preventing the refractory material of the main rod from contacting the ground or being placed on a flat surface, the specific technical solutions adopted by the present invention are as follows:

[0010] A split slag stop cone for a converter comprises a main rod and a cone head, wherein a core rod is passed through the interior of the main rod, and a cone sleeve and a socket plate are sleeved on the side wall of the core rod, an annular cavity is provided inside the cone head, a limiting groove is provided at the other end of the cone head, and a conical groove is provided on one side of the limiting groove, and a mounting hole is provided on one side of the conical groove, one end of the main rod passes through the mounting hole, the cone sleeve is located inside the conical groove, and the socket plate is located inside the limiting groove, a connecting screw is installed at one end of the main rod, and a threaded barrel and a supporting hole plate are sleeved on the side wall of the connecting screw, and a refractory shell is provided on the outer wall of the threaded barrel.

[0011] Furthermore, the connecting screw and the threaded barrel threads cooperate with each other.

[0012] Furthermore, the sleeve plate and the supporting orifice plate have the same diameter and length.

[0013] Furthermore, multiple groups of inclined tubes are passed through the interior of the annular cavity, and filter covers are provided at the facing ends of the multiple groups of inclined tubes. A built-in groove is provided at the other end of the cone head. An air guide tube is passed through the annular cavity and the built-in groove, and a control valve is provided on the side wall of the air guide tube.

[0014] Furthermore, the diameter length of the outer wall of the refractory shell is the same as the diameter length of the vertical section of the main rod.

[0015] Furthermore, the outer wall of the cone head is provided with four groups of grooves.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the utility model provides a split slag stop cone for a converter, which has the following beneficial effects:

[0018] (1) The present invention adopts a socket plate and a support hole plate. When the split slag stop cone for a converter is actually used, the main rod can be placed on the ground or on a flat surface when transporting or transferring the main rod. Due to the presence of the socket plate and the support hole plate, the socket plate and the support hole plate first contact the ground or the flat surface, and the main rod will not hit or contact the ground. When the main rod and the cone head need to be assembled, the connecting screw and the threaded barrel thread cooperate with each other, and the operator rotates the refractory shell counterclockwise by hand. When the threaded barrel is separated from the connecting screw, the support hole plate can be removed, and then the threaded barrel is socketed on the side wall of the connecting screw in a clockwise direction. Since the diameter length of the outer wall of the refractory shell is the same as the diameter length of the vertical section of the main rod, the refractory shell will not hinder the normal use of the main rod. At the same time, the socket plate can increase the stability of the main rod and the cone head. By setting the socket plate and the support hole plate, the refractory material of the main rod can be prevented from contacting the ground or the flat surface, which provides a guarantee for the transportation and handling of the split slag stop cone for a converter.

[0019] (2) The utility model adopts an annular cavity. According to the above operation, the main rod and the cone head are stored, transported or carried separately. Due to the existence of the mounting hole, the conical groove and the limit groove, external dust or impurities will enter the interior of the mounting hole, the conical groove and the limit groove. At this time, the operator can connect one end of the air guide tube to the output end of the external inflation device. At this time, when the external inflation device is working, air can be filled into the interior of the annular cavity. The air inside the annular cavity can be ejected through multiple groups of inclined tubes. The ejected air can blow out the dust or impurities inside the mounting hole, the conical groove and the limit groove, which is convenient for the subsequent installation and use of the main rod. The multiple groups of filter covers can prevent dust or impurities from entering the interior of the multiple groups of inclined tubes. The set annular cavity can facilitate the cleaning of dust or impurities inside the cone head connection hole, thereby improving the practicality of the split slag retaining cone for the converter.
