Abstract
The utility model relates to a temperature control and cooling control device for a feeding system of a continuous steelmaking electric furnace. The temperature control and cooling control device for the feeding system of the continuous steelmaking electric furnace comprises three water-cooling disks, namely a fixed disk, a disk A and a disk B, wherein a jet device is arranged in front of and at the back of a cover A of the disk A; and a manual regulating valve and an electric control valve which is interlocked with a smelting oxygen blowing controller are arranged on a water inlet pipe of the jet device. The production halt of the electric furnace caused by feeding inavailability due to tight adhesion of spattered steel slag in the electric furnace to the water-cooling disks of the feeding system is prevented. Meanwhile, the using temperature of each water-cooling disk in the feeding system is effectively reduced, so that the service life of each water-cooling disk is greatly prolonged, and the cost of spare parts such as the water-cooling disks is greatly reduced.
Description
Technical field
The utility model belongs to temperature control controlled cooling device technical field, relates on a kind of continuous steelmaking electric furnace feed system of the 90t of being applied in continuous steelmaking electric furnace, is used for the continuous steelmaking electric furnace feed system temperature control controlled cooling device to this zone cooling.
Background technology
Explanation of nouns: the Consteel electric furnace refers to the continuous steelmaking electric furnace.The 90t of factory continuous steelmaking electric furnace is rolled in refining has made the electricity consumption converter process, and the continuous steelmaking electric furnace changes into after the converter of continuous steelmaking electric furnace electricity, makes the production cost of steel that huge variation take place on the one hand.Drop to 2445 yuan/t as certain steel mill's electric steel production cost in 2006 by 3333 yuan original/t, the ton steel reduces by 888 yuan, has obtained good economic benefits.But because the characteristics of continuous steelmaking electric furnace, behind process reform, also bring very big change to conditions for equipment use, it is big to be mainly reflected in the molten iron add-on, exhaust gas volumn is multiplied, flue-gas temperature is corresponding rising also, be up to 1600 ℃, greatly reduce the work-ing life of aqueous cold plate in the feed system, particularly along with the quickening of smelting rhythm, aqueous cold plate continuous high temperature time lengthening in the feed system, the easy sticking stagnant water cold dish of splash slag in the smelting process, the thin material steel scrap that transports easily burns phenomenons such as molten sticking stagnant water cold dish, thereby cause not adding steel scrap and blowing out, become a big problem of influence production and cost, the tackling key problem that therefore is necessary to try every possible means improves.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art
,The utility model provides a kind of aqueous cold plate that can prevent the sticking dead feed system of splash slag in the electric furnace, can effectively reduce the use temperature of each aqueous cold plate in the feed system, the continuous steelmaking electric furnace feed system temperature control controlled cooling device that significantly prolongs the work-ing life of aqueous cold plate.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of continuous steelmaking electric furnace feed system temperature control controlled cooling device, comprise that shaft collar, A dish and B coil this three aqueous cold plates, before and after the A of A dish cover, be provided with jet apparatus, the water inlet pipe of jet apparatus be equipped with manual modulation valve and with the electrically-controlled valve of smelting oxygen blast control interlocking.
The water jet of described jet apparatus is contained on the high-temperature flue gas passage limit.
The water jet that described water jet designs for water storage.
The beneficial effects of the utility model are: prevent the aqueous cold plate of the sticking dead feed system of splash slag in the electric furnace, so that can't charging cause electric furnace to stop production; Also because effectively reducing the use temperature of each aqueous cold plate in the feed system, prolong the work-ing life of aqueous cold plate greatly simultaneously, also greatly reduced spare part expenses such as aqueous cold plate.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1,2,3, the 4-nozzle, the converter of 5-continuous steelmaking electricity, 6-shaft collar, 7-A dish, 8-B dish, 9-steel scrap, 10-water inlet pipe, 11-electrically-controlled valve, 12-drive unit.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Referring to Fig. 1, a kind of continuous steelmaking electric furnace feed system temperature control controlled cooling device, comprise that shaft collar, A dish and B coil this three aqueous cold plates, before and after the A of A dish cover, be provided with jet apparatus, the water inlet pipe of jet apparatus be equipped with manual modulation valve and with the electrically-controlled valve of smelting oxygen blast control interlocking; The water jet of described jet apparatus is contained on the high-temperature flue gas passage limit; The water jet that described water jet designs for water storage.
The converter of continuous steelmaking electric furnace electricity belongs to high-temperature molten steel and smelts, do not allow water inlet in the stove, otherwise the phenomenon of can blasting causes the production safety accident, and flue gas advances settling pocket and has not allowed liquid water to enter in the continuous steelmaking electric furnace feed system, otherwise can reduce in the settling pocket fire-resistant and material work-ing life; The utility model has the design feature of 4 aspects:
The one, before and after the A cover, adopt 4 injections, current will be concentrated and be mapped on the aqueous cold plate;
The 2nd, water flow is suitable, should prevent steel bonding, requires to go into the stokehold at steel scrap again and evaporates, and manual modulation valve has been installed for this reason;
The 3rd, according to smelting cycle and characteristics, the tapping time-temperature hangs down does not need water spray, then electrically-controlled valve is installed, and interlock automatic water jetting during oxygen blast with smelting oxygen blast control;
The 4th, water jet is because of on the high-temperature flue gas passage limit in continuous steelmaking electric furnace feed system, and temperature is very high, and water jet adopts the water storage design, does not go out during stop-spraying to burn out nozzle, guarantees that the water spray jet is normal.
After improving, three aqueous cold plates (shaft collar, A dish, B dish) have been stopped the steel bonding phenomenon in the continuous steelmaking electric furnace feed system, significantly reduced the fault off-time of therefore causing, aqueous cold plate to these three easy scaling loss uses surface temperature to descend greatly simultaneously, and making has increased by one times its work-ing life.
The utility model all reaches the expection requirement in December, 2011, reduced the steel bonding fault handling time about 4 hours average every month, and about 300,000 yuan of year minimizing spare parts consumption is for continuous steelmaking electric furnace electricity converter stable smooth operation has been brought into play great role.
The utility model is to adopt first at continuous steelmaking electric furnace and the converter of continuous steelmaking electric furnace electricity, has broken through the conventional thought that domestic and international preheating channel can not be sprayed water, and result of use is good, all has advanced level at home and abroad, is worthy of popularization.
