摘要： PURPOSE: Provided is a refining furnace slag recycling method being capable of natural friendly treating the slag at low cost in small area by excluding water treatment and dry processes. CONSTITUTION: The method comprises the steps of cooling slag lump for a predetermined time at room temperature; crushing the cooled slag; first sorting out crushed slag fragments having a size less than 200 mm; transferring the sorted out slag fragments to a rotary cooler while supplying cooling air of room temperature to the rotary cooler, thereby cooling hot slag to a low temperature; second sorting out slag fragments with a size no greater than 10 mm out of the slag fragments output from the rotary cooler using a screen and transferring the second sorted out slag fragments to a separating hopper; and sending slag fragments with a size no greater than 0.25 mm to a fertilizer plant.

摘要： PURPOSE: A filler punch of a ladle is provided to prevent a generation of an oxidized inclusion by isolating a contact between a melted steel with air. CONSTITUTION: In transferring a ladle(110) on a tundish(140), a long nozzle is fixed in a collect nozzle(112) with a jig(180). Vertical positions of the collect nozzle(112) and a top nozzle(111) are conformed by sliding a lower plate of a cassette(110). A branch pipe(10) is fixed in an electronic opening/closing device and raised up to a hardened filler(130). In raising the branch pipe(10), the branch pipe(10) lifts the filler(130) by guiding inside the long nozzle, the collect nozzle(112) and the top nozzle(111). Melted steel is flowed into the branch pipe(10) by depressing the filler(130). The top nozzle(111) is changed into red by flowing the melted steel from the ladle(100). A worker releases a fixing pin of the electronic opening/closing device from a branch pipe hook by discriminating the color change of the top nozzle(111). The branch pipe(10) is fallen into the tundish(140). A melted steel discharge port is formed inside a weight(12) to prevent a hardening of the melted steel inside the branch pipe(10) and to easily fall the branch pipe(10). The fallen branch pipe(10) remains in a slag layer by oxidizing after hardening inside the tundish(140).
摘要翻译：目的：提供钢包的填料冲头，以通过隔离熔融钢与空气之间的接触来防止产生氧化的夹杂物。构成：在中间包（140）上转移浇包（110）时，长的喷嘴用夹具（180）固定在收集喷嘴（112）中。收集喷嘴（112）和顶部喷嘴（111）的垂直位置通过滑动盒（110）的下板来实现。分支管（10）固定在电子开/关装置中并升高到硬化填料（130）。在分支管（10）的升高中，分支管（10）通过在长喷嘴，收集喷嘴（112）和顶部喷嘴（111）内部引导来提升填料（130）。熔化的钢通过压下填料（130）而流入分支管（10）。通过使来自钢包（100）的熔融钢流动，顶部喷嘴（111）变为红色。通过识别顶部喷嘴（111）的颜色变化，工人通过分支管钩释放电子打开/关闭装置的固定销。分支管（10）落入中间包（140）中。在重物（12）内形成有熔融钢排出口，以防止分支管（10）内的熔融钢硬化，并容易地使分支管（10）落下。落下的分支管（10）通过在中间包（140）内部硬化后氧化而保留在炉渣层中。
