Abstract
The invention relates to a design method of a converter cast iron water-cooling mouth, comprising the steps of: 1. designing shape size; 2. designing install size; 3. designing a converter cooling system; and 4. designing the main body material of the converter mouth. The converter cast iron water-cooling mouth has the following advantages and benefits: 1. water tight: a cast mode which is pre-cast with a cooling water pipe is adopted, the water pipe is shaped by means of cold bend, and the surface of the water pipe has a good protection layer, therefore, the cast iron water-cooling mouth is watertight; 2. no mending: the mouth is watertight, therefore, the mouth can be out of maintenance; 3. long service life: under the normal using condition, the cast iron converter mouth can use one converter campaign without needing to change the converter mouth to prevent from affecting the manufacture; 4. hard deformation; and 5. hard sludge adhering and easy sludge removing. Because the materialis different, the cast iron converter mouth is hard to be adheree with the sludge and easy to remove less quantity of the sludge.
Description
Technical field
The present invention relates to the structure design of metallurgy industry converter mouth, be specifically related to a kind of method of design of converter cast iron water-cooling mouth.
Background technology
Converter is one of steelworks most important equipment, and converter mouth is again the important accessory of converter.Converter mouth should be designed on the basis of converter, and the substance of its design can be summarized as three key elements, the design of physical dimension, the design of installation dimension, fire door Cooling System Design.All the other should also be noted that the connecting mode or the like of weight, water flowing pressure, fire door cooling tube and the converter cooling system of furnace water-cooling mouth.
The defective of existing steel construction furnace water-cooling mouth mainly contains:
1, easily leaks.The steel construction furnace water-cooling mouth is to be welded by steel plate, owing to be weldment, leaking easily under the high-heat strength for a long time, brings very big trouble to converter steelmaking.
2, inconvenience is repaired.After the steel construction furnace water-cooling mouth leaks, need to repair leak stopping, but converter can not blowing out, so must carry out repairing work under hot state, the thermal radiation that the operating personnel bore is very big, and people's health, safety, working efficiency all had very big influence.Concerning all steelworkss, the repairing leak stopping of steel construction furnace water-cooling mouth all is an a great problem.
3, work-ing life is short.The work-ing life of steel construction furnace water-cooling mouth is shorter, generally just needs to change fire door less than a stove labour, brings very big influence to production.
4, yielding.Owing to be the weldment of steel construction, nearly all parts all are to be welded by steel plate, and under the long working order of high-heat strength, the steel construction fire door easily produces distortion.
5, easily dry slag and slagging-off are difficult.The steel construction fire door is close with the molten steel material, easily combine with molten steel, and slagging-off is relatively more difficult, causes fire door to leak in the slag removal easily.
In order to address the above problem, Chinese patent publication number CN2797382 has disclosed between a kind of revolving furnace water-cooling mouth and the trunnion of converter water pipe in order to the delivery cycle water coolant, the water coolant pipe connecting of revolving furnace water-cooling mouth particularly, comprise the fixedly water pipe that is connected on revolving furnace water-cooling mouth and the trunnion of converter, two fixedly are installed with hydrant pipe rapid-acting coupling respectively on the free end of water pipe, are connected by metallic hose between the two hydrant pipe rapid-acting couplings.
Chinese patent publication number CN101474738 has disclosed a kind of making method of revolving furnace water-cooling mouth, belongs to the converter installation technical field.The use steel plate is made, and step is: according to the blanking of drawing dimensional requirement; Simmer ring in the system furnace water-cooling mouth; On platform, splice base plate, upper cover plate; The furnace water-cooling mouth assembly welding is become as a whole.Solved cost height, interior ring that traditional manufacturing technique exists be prone to crackle, part position can't repair welding, life cycle weak point, maintenance of equipment expense height, going wrong influences the production time and problems such as grows.
But in actual use, above-mentioned two disclosed technology and existing steel construction furnace water-cooling mouth remain in some shortcomings.
In view of this, seek a kind of method of design of converter cast iron water-cooling mouth of system, become pursuing one's goal of these those skilled in the art.

(14) set cooling surface thickness H3;
(15) set fire door total thickness H0;
(16) set fire door distinguish method.
In the described step (16), fire door is a kind of in 2 lobes, 3 lobes, 4 lobes, 6 lobes.
Described step (2) comprising:
(21) set the open holes diameter;
(22) set open holes thickness;
(23) setting open holes distributes;
(24) set the distribution diameter Φ so of open holes on fire door.
Described step (3) comprising:
(31) the cooling tube clod wash becomes serpentine tube;
(32) cooling tube end outlet design;
(33) cooling tube selects for use;
(34) check after cooling tube bends;
(35) connection of cooling system.
In the described step (31), the cooling tube after the bending should be through the logical ball and the water test.
When the working face of fire door and flange mounting face during, also comprise the configuration design of fire door before in step (1) basically not on same plane.
Adopt the converter cast iron water-cooling mouth of the present invention's design, have the following advantages and positive effect:
1, water-tight.Owing to adopt the forging type of pre-buried water-cooled tube, and water pipe is to adopt cold roll forming, and the water pipe surface has good protective layer, so cast iron water-cooling mouth can not produce the phenomenon of dew.
2, need not repair.Because water-tight, but cast iron water-cooling mouth maintenance-free.
3, long service life.Generally under normal service condition, the cast iron fire door can use a stove labour, need not change fire door midway, production is not impacted.
4, not yielding.
5, be difficult for dry slag and slagging-off easily.Because the material difference so the cast iron fire door is difficult for dry slag, has a small amount of dry slag also more easily to remove.
