Abstract

The invention relates to a quick-change multifunctional coherent oxygen lance, which consists of an elbow, a steel pipe, a connecting pipe, a quick-change joint, a steel pipe, a main oxygen inlet, a fuel gas inlet, a water inlet, an epoxide inlet, a water outlet, and a fixed plate. The quick-change multifunctional coherent oxygen lance is mounted on a steelmaking electric furnace wall, is used forjetting oxygen and fuel gas, has all parts connected by pipe grippers, is convenient for quick change of parts, and saves the repair and maintenance time, the main oxygen, fuel gas and epoxide inletsall adopt pipe grippers for connection with an external gas supply pipeline, thus being convenient for quick change of connection hoses. The quick-change multifunctional coherent oxygen lance is splittable, can achieve change of only a damaged part under a damaged condition, can save the use cost, is equipped with cooling water inflow and return setting in itself, and has greatly improved servicelife.

Description

【Technical field】 [0001] The invention relates to a cluster oxygen lance, in particular to a quick-change multifunctional cluster oxygen lance. 【Background technique】 [0002] With the needs of social development, the demand for steel products is huge. At present, human beings have adopted a large number of electric furnace steelmaking methods. Electric furnace steelmaking has the characteristics of fast rhythm. In the steelmaking process, it is required to minimize or even use spare parts Maintenance, which requires long service life of steelmaking components, maintenance and replacement of components need to be fast, the current device can not meet this requirement. [0003] Therefore, a quick-change multifunctional cluster oxygen lance is needed, which is installed on the furnace wall of the steelmaking electric furnace for injecting oxygen and gas. Each part is connected by a pipe clamp, which is convenient for quick replacement of parts and saves maintenance time. Its m...
