Embodiment 1

[0027] Such as figure 1 As shown, an oxygen-filling multifunctional reamer, the outermost layer in the spindle drill rod of the reamer is set as the backwater cavity (2), and the second layer is set as the water inlet cavity (1), the innermost The layer is set as an oxygenation chamber (3), three oxygenation holes (5) evenly arranged along the circumference are set on the top of the drill bit. The cutter head assembly is fixed on the reamer drill bit by bolts, and the drill bit and the spindle drill rod are connected The connecting flanges (31) are connected together. During the reaming work, as the drill bit is drilled, automatic oxygenation is performed at the same time, which solves the problem of no "cold steel" reaming, circulating water cooling setting, lowering the working temperature, and thus Ensure the mechanical strength of the drill bit and drill pipe components. The generated waste slag is quickly flushed out along the automatic slag discharge slot (6) under the imp...

Embodiment 2

[0031] Such as figure 1 As shown, an oxygen-filling multifunctional reamer, the outermost layer in the main shaft drill rod of the reamer is set as the pipe of the return water cavity (2), and then enters the pipe of the water inlet cavity (1). The innermost layer of the pipeline is set as the oxygenation chamber (3). On the top of the drill bit, there are 4 oxygenation holes (5) evenly arranged along the circumference. The cutter head assembly is fixed on the reamer drill bit by bolts. The drill bit and the spindle drill rod are connected by a connecting flange (31). When the drill bit is drilled, oxygen is automatically filled at the same time as the drill bit is drilled. This solves the problem of no "cold steel" reaming and circulating water cooling settings. The working temperature is lowered to ensure the mechanical strength of the drill bit and the drill pipe components. Under the impact of the airflow, the generated waste residue is quickly flushed out along the automati...

Abstract

The invention discloses a multifunctional oxygenation reamer, and relates to the technical field of metallurgy. The multifunctional oxygenation reamer comprises the following components of a main shaft drill rod, a water inlet cavity, a water return cavity, an oxygenation cavity, tool bit assemblies, an oxygenation hole and an automatic deslagging slotted hole structure. The multifunctional oxygenation reamer is capable of automatically deslagging, and reaming can be completed through complete drilling; during the reaming, the multifunctional oxygenation reamer adopts an automatic oxygen blowing function, and 'cold steel'-free reaming is solved; circulating water can be automatically supplied during the reaming, so that a cooling function is realized, and the problems of hardness and strength of the multifunctional oxygenation reamer at a high temperature are solved; automatic deslagging can be realized, a deslagging problem of slag generated during a reaming process can be highly efficiently and highly qualitatively solved, blocking is not caused, and the reaming speed is quickened; the reaming can be completed through complete drilling, and a reaming task can be completed by repeating for many times under the situation that tool bits require not to be changed; a single tool bit of the multifunctional oxygenation reamer can be quickly changed, the diameter of the tool bits isfurther lessened by comparing with the diameter of a traditional tool bit, the using amount of an alloy material of the tool bits is relatively saved, and the production cost is further reduced.

Description

Technical field [0001] The invention belongs to the field of metallurgical technology, and more specifically relates to an oxygen-filling multifunctional reamer. Background technique [0002] The quality and use efficiency of the taphole reamer in steel smelting are directly related to the quality of the product and the efficiency of the entire process. Therefore, the development of a new type of reamer is an important measure for technical research. A comprehensive view of traditional reamers and The reamer that has been developed still has many technical defects that require further technical innovation. For example, some reamers are easy to wear in the presence of cold steel, because the tap hole must be drilled immediately after the steel is smelted. The reamer of the reamer expands in a high temperature environment and has a short service life, which restricts the improvement of quality and efficiency in the metallurgical industry. [0003] After searching: a steel-making con...
