[0030] The invention is applied in the steel slag hot-simmering pool of Taidong Industrial Co., Ltd. of Laiwu Iron and Steel Group. The design of the explosion-proof device used for steel slag heating is as follows: the protective cover 1 is conical, the diameter of the bottom surface is 540mm, the diameter of the flange 3 is 460mm, the design height between the protective cover 1 and the flange 3 is 200mm, and it is evenly distributed by three connecting rods 2 connect. The gas inlet and outlet 6 in the flange 3 is designed to be a square with a side length of 135mm. The bottom of the gas inlet and outlet 6 is provided with a movable tongue 5 with a thickness of 3mm and a side length slightly larger than the gas inlet and outlet 6, which cooperates with the gas inlet and outlet 6 and can close the gas inlet and outlet 6; 5 and flange 3 are stationary at an angle of 40°. Above-mentioned movable tongue piece 5 adopts high temperature resistant, anti-corrosion stainless steel ...

The invention relates to an explosion-proof device for steel slag hot braising. The explosion-proof device for steel slag hot braising comprises a protective guard (1), a plurality of connecting rods (2) and a flange (3). The protective guard (1) is connected with the flange (3) through the connecting rods (2). A gas inlet and outlet (6) is formed in the middle of the flange (3). A movable tongue piece (5) is arranged at the bottom of the gas inlet and outlet (6) and is connected with one side edge of the gas inlet and outlet (6) through a hinge (4). The movable tongue piece (5) freely moves in the direction opposite to the protective guard through the hinge (4) within the 0-40 degree scope of an angle formed by the movable tongue piece (5) and the flange (3). When a 0-degree angle is formed between the movable tongue piece (5) and the flange (3), the movable tongue piece (5) is matched with the gas inlet and outlet (6) and covers the gas inlet and outlet (6) in a sealed mode. The explosion-proof device ensures that a hot braising pool can be used for practically and effectively carrying out a steel slag pulverization process, and achieves higher slag-iron separation rate.
Description
technical field [0001] The invention relates to the technical safety field of iron and steel metallurgical slag recycling and comprehensive utilization, in particular, the invention relates to an explosion-proof device for steel slag thermal braising. Background technique [0002] The pulverization treatment of steel slag and the separation of slag and iron are an important link in the recycling of slag and iron resources in iron and steel enterprises and the effective reduction of steelmaking costs. At the same time, the instability of steel slag is also a key issue restricting the comprehensive utilization of steel slag. At present, steel slag hot-stewing treatment technology is generally used to tip the molten steel slag in the hot-steaming device, seal the cover, and spray water. Water meets hot slag to generate steam, which makes steel slag undergo a chemical reaction, and the free calcium oxide expands in volume and breaks and pulverizes under the action of temperature...
