This disclosure relates to the field of high-titanium slag blast furnace smelting technology, and particularly to a method for restoring a high-titanium slag blast furnace after a shutdown. The method includes: reducing the coke load by 13% to 18% 4-5 hours before the shutdown; adding clean coke 3-4 hours before the shutdown, and adjusting the charging system to: a 3-ring ore charging system, with the ore platform's radial angle width ranging from 3° to 4°, the outer coke-ore angle difference ranging from 1.5° to 2°, and the inner ore-coke angle difference ranging from 5.5° to 6°; and controlling the pig iron [Ti] content to 0.15% to 0.20% and the slag binary basicity to 1.04 to 1.08 times the standard basicity starting 1-2 hours before the shutdown. This disclosure allows for rapid restarting of a high-titanium slag blast furnace after a long shutdown.

This utility model relates to the field of drying equipment and provides a hot air drying device for dehydrated vegetables. It includes an outer cylinder and an inner cylinder installed inside the outer cylinder, both with openings at the top. The bottom and sides of the outer cylinder have air inlets and outlets, respectively. A fan structure is installed at the bottom of the inner cylinder. A circulation chamber is provided between the outer and inner cylinders. A first heating grid is located between the inner bottom of the outer cylinder and the inner cylinder, and a second heating grid is located between the inner top of the outer cylinder and the inner cylinder. The top of the outer cylinder has a removable cover, and the bottom of the cover has several trays at different heights. This device effectively solves the problem of uneven hot air distribution in existing drying equipment. The synergistic effect of the inner and outer cylinders ensures that the hot air is evenly distributed within the inner cylinder, avoiding over-drying and scorching of vegetables due to excessively high local temperatures. This not only significantly improves the quality of the dehydrated vegetables but also greatly shortens the drying time and increases drying efficiency.
