Embodiment 1

[0020] Example one: such as figure 1 , figure 2 As shown, a new type of slag basin for separating phosphorus in converter slag includes a slag basin body 1 and an upper portion 2 of the slag basin body 1 installed above the slag basin body 1. The slag basin body 1 is in the shape of an inverted truncated cone. The upper part 2 is a cylindrical shape with a thick top and a thin bottom. The lime block 3 is placed in the slag basin body, and the lime block is in a basin shape as a whole, and the bottom surface of the lime block fits with the slag basin body. The upper surface of the lime block 3 is provided with a plurality of vertical slot holes 31 arranged in an array, the slot holes 31 have a diameter of 5 mm, the distance between the centers of the slots 31 is 8 mm, and the distance between the bottom surface of the slot holes and the bottom surface of the lime block is 50 mm. In this state, the low-phosphorus liquid slag can flow smoothly into the deep holes, and the slot ho...

Embodiment 2

[0029] Embodiment two: such as image 3 As shown, a new type of slag basin for separating phosphorus in converter slag includes a slag basin body 1 and an upper portion 2 of the slag basin installed above the slag basin body 1. The slag basin body 1 is in the shape of an inverted truncated truncated cone. The upper end of the slag basin body 1 is provided with a thread 11, the upper part 2 of the slag basin is a cylindrical shape with an upper thickness and a fine lower end, and the lower end is provided with a thread 11 matching the slag basin body 1 , The two can be sealed and fixed by screwing together, fast installation and tight fixing. The lime block 3 is placed in the slag basin body, the lime block is in a basin shape as a whole, and the bottom surface of the lime block fits with the slag basin body. The upper surface of the lime block has a downward concave surface, which increases the contact area between the liquid slag and the lime block and accelerates the separat...

Abstract

The invention provides a novel slag basin for separating phosphorus in converter slag. The novel slag basin comprises a slag basin body and a slag basin upper portion mounted above the slag basin body, lime blocks adaptive to the slag basin body are arranged in the slag basin body, and multiple slotted holes are formed in the upper surfaces of the lime blocks. In addition, the invention further provides a manufacturing method and a using method of the novel slag basin. The novel slag basin is simple in structure, can be used for containing converter slag, and the high phosphorus constituent in the converter slag can be separated to obtain high iron slag. The high iron slag can be used as iron-making sintering materials, stacking space is saved, the effective utilization rate of iron and steel resources is improved, and the production cost of steel enterprises is lowered.

Description

Technical field [0001] The invention belongs to the field of converter slag resource recovery and utilization in the converter steelmaking process, and in particular relates to a novel slag basin for separating phosphorus in converter slag and a manufacturing method thereof. Background technique [0002] With the rapid development of China's iron and steel industry in the past ten years, the emissions of converter slag, a by-product of iron and steel smelting, have also increased year by year. The metallurgical industry is paying more and more attention to the recycling and utilization of a large amount of converter slag. However, the treatment and utilization of steel slag in my country is still in a relatively backward state. A large amount of converter slag has not been effectively treated and utilized. Some steel companies are already full of slag, affecting production and causing environmental pollution. After the implementation of the new environmental protection law, steel...
