Description
Technical field
The utility model belongs to technical field of metallurgical equipment, further belongs to ladle pouring equipment technical field, is specifically related to a kind of simple in structurely, makes easily, easy and simple to handle, uses safety, can the effectively heat insulation steel ladle cover that prevents external heat radiation damage.
Background technology
China is world Chan Gang big country, and steel-making has realized continuous casting operation, and in continuous casting operation, cast temperature is one of important parameter.Because existing ladle is larger, general weight is greater than 200 tons, so casting time is longer.As the billet caster of 7 machine 7 streams 165 * 165, when pulling rate is 2.3 ms/min, casting time is 38 minutes.The large square bland continuous-casting machine of 5 machine 5 streams 230 * 230, when pulling rate is 1.2 ms/min, casting time is 45 minutes; If the rectangular bloom that casting section is 230 * 350, when pulling rate is 0.7 m/min, casting time is 45 minutes; If the rectangular bloom that casting section is 320 * 410, when pulling rate is 0.4 m/min, casting time is 45 minutes.Casting time changes with the difference of pulling rate and steel grade.When in casting cycle, molten steel thermal loss is more, temperature drop can surpass 50 degrees Celsius, and the temperature of molten steel reduces by 20 ~ 50 degrees Celsius and will cause and cast unsuccessfully.In addition, cast temperature is on the low side, and meeting is clamminess molten steel, and field trash is difficult for floating, easily makes crystallizer surface molten steel scull, causes surface defect of bloom.In order to reduce the temperature drop of molten steel in casting cycle, so cover steel ladle with steel ladle cover, be incubated; Meanwhile, steel ladle cover can protect the hydraulic system on cable testing bridge, Crane Rail and turntable top on steel ladle rotary table to avoid high-temperature baking, abatement apparatus hidden danger and potential safety hazard.The steel ladle cover of prior art, its structure is extremely unreasonable.First, steel ladle cover diameter is too large, and steel ladle cover diameter has surpassed the external diameter of ladle mouth, when steel ladle cover covers lower time, the refractory material of steel ladle cover directly contacts with ladle mouth, and the circular outer rim of steel ladle cover is stretched outside ladle mouth, in very short time, will be burned, cause whole steel ladle cover to lose efficacy, scrap.Secondly, the steel ladle cover degree of depth is inadequate, is generally less than 80mm, can be less than 68mmmm by filling fire resisting material thickness, because refractory material is few and thin, within general 44 days, will be burnt.Secondly, steel ladle cover arranges 4 lifting hangers, is that 90 degree are evenly distributed, and is difficult to make steel ladle cover to set up during installation again, and installation is wasted time and energy.In addition, the steel structure support at the base plate of steel ladle cover and the steel ladle cover back side is with bolts, be not easy to installation, Problem, and service life is short.So the steel ladle cover of prior art is short service life, difficulty is installed, maintenance is difficult for, and has increased the production cost of enterprise, has increased operating personnel's labour intensity simultaneously.For this reason, research and develop a kind of simple in structurely, make easily, easy and simple to handle, use safety, can effectively heat insulationly prevent that the steel ladle cover of external heat radiation damage from being the key addressing this problem.
Utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, and makes easily, easy and simple to handle, uses safety, can the effectively heat insulation steel ladle cover that prevents external heat radiation damage.
The purpose of this utility model is to realize like this, comprise support, steel ladle cover base plate, refractory material, installation hanger, lifting hanger, steel ladle cover cylinder, described support top arranges installation hanger, and circumferential edge arranges lifting hanger, and bottom and steel ladle cover base plate are affixed; Outside described steel ladle cover base plate, circumferential edge and steel ladle cover cylinder upper end are affixed; Outside described steel ladle cover cylinder, the bag of a footpath and ladle mouthful external diameter size adapts; Within described steel ladle cover cylinder, refractory material is set.
The utility model adopts thickening refractory material, reduces the structure of steel ladle cover excircle dimension; Steel ladle cover arranges 3 lifting hangers simultaneously, and 120 degree are evenly distributed; Steel ladle cover base plate and support are Welding Structure.Steel ladle cover is outer through in the same size with ladle mouth external diameter, has avoided the circular outer rim of steel ladle cover to stretch the phenomenon being burned at ladle mouth outward; Refractory thickness has effectively extended service life after increasing; 3 lifting hangers are set, convenient and swift during installation; Steel ladle cover base plate and support welding, install, overhaul, safeguard very convenient, long service life.Adopt after said structure, greatly extended the service life of steel ladle cover, the life-span can reach more than 172 days, and installs, overhauls easily, has reduced operating personnel's labour intensity simultaneously, has improved the economic benefit of enterprise.The utility model is simple in structure, makes easily, easy and simple to handle, uses safety, can be effectively to the heat insulation external heat radiation damage that prevents of steel ladle cover.
