A ladle baking table

Abstract

The invention relates to metallurgy pouring ladle baking. A hanging column (23) of a cantilever sling is provided with a single-cantilever sling (22) and a double-cantilever sling (27). The single-cantilever sling (22) is used for hoisting a ladle cover (3) of a fire baking ladle (7). The ladle cover (3) rotates and moves to provide hoisting space for the fire baking ladle (7) to be hoisted out or in. The double-cantilever sling (27) is used for hoisting a ladle cover (3) of a heat baking ladle (8) and rotates and moves to provide hoisting space for hoisting out or in. The single-cantilever sling (22) is also used for hoisting a stand pipe (24), and therefore the double-cantilever sling (27) can hoist the ladle cover (3) of the heat baking ladle (8) for rotation and displacement. A heat flow pipe (12) is connected with the fire baking ladle (7) and the heat baking ladle (8). The ladle cover (3) of the fire baking ladle (7) is provided with a spraying port (20) spraying oxygen to assist in combustion of fuel gas sprayed by a spraying pipe (5), flame heat flow flows into the heat flow pipe (12) through a water port hole or a seat brick hole and flows into a water port hole of the heat baking ladle (8) through the heat flow pipe (12) to bake the heat baking ladle (8).

Description

technical field [0001] The invention relates to metallurgical ladle baking, especially steel ladle baking. . Background technique [0002] The vast majority of existing ladle baking energy wastes are astonishing. Thermal calculations show that the heat utilization rate of ladle baking is less than 2%, and more than 98% of heat energy is wasted. For example: a 100t steel ladle is about 9000Kg of refractory materials, and the newly built 100t steel ladle needs to be baked for 80-100 hours before it can be used, and the average baking time is about 4.5m per minute. 3 Calorific value is 9196KJ / m 3 Gas or converter gas, a total of about 21600 m 3 Gas, 21600 m 3 Gas is about 198635600 kJ heat energy, equivalent to 6777.7Kg standard coal. For a ladle of 10000 kg refractory material, the inner surface is baked to 100°C, and the outer surface reaches the applicable standard of 170°C. At this time, the specific heat capacity of the refractory material is calculated as 0.74kJ / kg:...

Although the invention of ZL200910120000.4 is a good way to save energy by thermal energy ladder utilization, it is not suitable for most steel enterprises. At present, most steel enterprises urgently need to implement a simple and easy series baking method for brick ladles to realize thermal energy ladder utilization and energy saving. Reduce consumption and maintain low-cost production
