Abstract
The utility model provides a wear-resistant air port for a blast furnace. In the furnace air port, a wear-resistant bushing (5) is embedded or cast in the circumferential direction on the inner side of a hot air passage (4) to resist corrosion and attrition of pulverized coal for a longer time, thereby greatly prolonging the service life of the air port, reducing the downtime percentage of the blast furnace and facilitating the stable production of the blast furnace; the wear-resistant bushing (5) embedded or cast in the hot air passage has a certain heat insulation function, thereby reducing the heat loss and facilitating the energy saving of the blast furnace.
Description
Technical field
The utility model relates to ironmaking tuyere of blast furnace, mainly is a kind of new type BF tuyere of around hot-air channel, inlaying or being cast with anti-wearing liner.
Background technology
The blast furnace that is used to smelt iron needs also need pass through air port coal injection in stove simultaneously through air port heat air delivery in stove; Because coal dust is a particulate state, in case spray gun deflection or other reasons cause the blast-furnace tuyere wearing and tearing easily; After the air port is worn, in stove, leak easily, safety in production impacts to blast furnace for fear of leaking, and generally all needs in time to change to damaging the air port; Just can carry out after the air port needs blast furnace staying to stop production yet change,, will have a strong impact on blast furnace steady running if blast furnace needs frequent damping down to stop production because of changing reasons such as air port; To cause the blast furnace energy consumption to raise, influence the blast furnace economic benefit, therefore; Damage quantity and improve air port work-ing life in order to reduce the air port, release a kind of new type BF tuyere of around hot-air channel, inlaying or being cast with anti-wearing liner especially, reduce the blast furnace staying rate according to this; Improve the operation of blast furnace quality, improve the blast furnace economic benefit.
The utility model content
The technical assignment of the utility model is the deficiency to above-mentioned existing blast-furnace tuyere, and a kind of new type BF tuyere that can prolong the air port life-span of around hot-air channel, inlaying or being cast with anti-wearing liner is provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: it is by tuyere body, cooling water cavity, water coolant spiral channel, hot-air channel, anti-wearing liner, and the air port into and out of the water hole or ME hole, air port form; Hot-air channel is through tuyere body; Anti-wearing liner is inlayed or is cast in around the hot-air channel on the tuyere body; Cooling water cavity is arranged in the tuyere body posterior segment in the form of a ring; The water coolant spiral channel around the hot-air channel of tuyere body leading portion with foremost, the air port into and out of the water hole or ME hole, air port on the aft end face of air port, and pass air port aft end face and cooling water cavity UNICOM; Anti-wearing liner also can be inlayed or cast to use and have only on the tuyere body of cooling water cavity; Anti-wearing liner also is applicable to the tuyere body that hot-air channel is downward-sloping; As long as the blast-furnace tuyere of inlaying or being cast with anti-wearing liner all belongs to this patent.
A kind of blast furnace of the utility model with wear-resisting air port compared with prior art; Have following outstanding advantage and beneficial effect: because this air port is inlayed or cast anti-wearing liner in hot-air channel; Can resist coal dust the long period and wash away, therefore, can improve greatly the air port life-span; Reduce the blast furnace staying rate, it is stable to help blast furnace production; The wear-resisting lining of inlaying in the hot-air channel is with certain heat-blocking action, can reduce calorific loss, helps energy Conservation of Blast Furnace.
