Abstract
The invention aims to provide a slag casting device for metallurgical pre-melted slag production, and the slag casting device can be used for continuously producing granulated pre-melted slag adaptable to user needs without subsequent crushing treatment. By using the novel metallurgical pre-melted slag casting device, the pre-melted slag can be efficiently and continuously shaped, cooled and granulated. The device has the advantages of simple equipment, low investment and quick effect, is convenient to operate, and can be used for continuously producing pre-melted slags different in granularity and adaptable to the user needs without subsequent crushing treatment, simultaneously solving the problem of environmental pollution and improving the production efficiency.
Description
Technical field
The present invention relates to a kind of metallurgical pre-melted slag casting slag device, belong to the metallurgical technology technical field.
Background technology
At present in steel-making and refining process, along with the pursuit of people to pureization of steel, and the technical need of producing high value added product, metallurgical pre-melted slag is more and more adopted, and removes unnecessary phosphorus, sulphur and non-metallic inclusion in the steel.Traditional metallurgical pre-melted slag production method adopts substantially produces the product that is fit to customer need with casting and cooled pre-melted slag by the mode of fragmentation.The production efficiency that adopted the serious restriction of this kind mode of production produces a large amount of dust simultaneously in shattering process, not only caused environmental pollution, and reduced yield rate, can not adapt to current enterprise to environmental protection, and is low-cost, produce and pursue efficiently.Therefore, need a kind of novel metallurgical pre-melted slag casting slag device of exploitation, satisfy the demand that enterprise produces.
The casting slag device of publication number is that CN101205562's mention in " a kind of metallurgical cinder treatment process and treatment unit " metallurgical slag comprises slag reduction unit, refrigerating unit and shredder assembly, metallurgical cinder is rolled into sheet slag thing by the slag reduction unit, and externally output continuously; Carry out quick cooling by an equipment water jetting cooler then and handle, enter a shredder assembly, carry out granulated processed and form slag particles through cooled slag thing.Though the production metallurgy pre-melted slag that this device can high-efficiency and continuous, this apparatus and process complexity might increase production cost; This device need will inevitably change the thing phase composite of slag to the slag cooling of spraying water in addition, will influence the use properties of product; Equally, this device also needs to carry out break process, also can bring an environmental pollution difficult problem, and reduces production efficiency.
The objective of the invention is the problem that exists at foregoing invention and in conjunction with the practical situation of the metallurgical pre-melted slag of domestic production, the casting slag device that is fit to metallurgical pre-melted slag more of exploitation.Present device is simple, and is easy to operate, need not to carry out follow-up break process and can continuously produce the granulation pre-melted slag that is fit to customer need, also solved the pollution problem to environment simultaneously, improved production efficiency, invest for a short time, produces effects soon.
Summary of the invention
The purpose of this invention is to provide a kind of casting slag device that metallurgical pre-melted slag is produced that is used for, need not to carry out follow-up break process and can continuously produce the granulation pre-melted slag that is fit to customer need.
In order to reach the foregoing invention purpose, the present invention by the following technical solutions:
The casting slag device that a kind of metallurgical pre-melted slag is produced is made up of slag trough, casting slag device, casting slag pit, watercooling jacket, water-in, water outlet six parts;
It is characterized in that: slag trough is positioned at an end of casting slag device, is made into circular arc type by refractory metal, and links together with casting slag device; Casting slag device also is made by refractory metal, and its transverse section is rectangle or circular arc; Evenly distributed several measure-alike casting slag pits on whole casting slag device plane, casting plane, slag pit place will be lower than the limit portion of casting slag device, to prevent overflowing casting slag device after slag from filling with casting slag pit; Casting slag pit is semisphere, mouthful wide end narrow circular platform type or mouthful narrow trapezoidal shape in the wide end; The peripheral solder of casting slag device has a circle watercooling jacket, and watercooling jacket is made by corrosion-resistant metal materials, in the perforate of watercooling jacket two ends, and one section welding water-in, other one section welding water outlet.
Utilize novel metallurgical pre-melted slag casting slag device; can high-efficiency and continuous pre-melted slag is carried out moulding, cooling, granulation; this appliance arrangement is simple; easy to operate; need not to carry out follow-up break process and can continuously produce the varigrained pre-melted slag that is fit to customer need, also solved pollution problem simultaneously, improved production efficiency environment; invest for a short time, it is fast to produce effects.

Embodiment
The invention will be further described below in conjunction with embodiment:
The present invention implements in the following way:
The casting slag device that a kind of metallurgical pre-melted slag is produced, this device is made up of slag trough 3, casting slag device 2, casting slag pit 4, watercooling jacket 1, water-in 5, water outlet 6 six parts; It is characterized in that: slag trough 3 is positioned at an end of casting slag device 2, is made into circular arc type by refractory metal, and links together with casting slag device 2, and it is mainly used to accept from the effusive slag of slag notch, and slag is injected casting slag device 2; Casting slag device 2 also is made by refractory metal, and its transverse section can be rectangle or circular arc; Evenly distributed several measure-alike casting slag pits 4 on whole casting slag device 2 planes, casting plane, slag pit 4 place will be lower than the limit portion of casting slag device 2, to prevent overflowing casting slag device 2 after slag from filling with casting slag pit 4; Casting slag pit 4 can be that semisphere also can be narrow circular platform type or mouthful narrow trapezoidal shape in the wide end of mouthful wide end, so that the clinker demoulding; The peripheral solder of casting slag device 2 has a circle watercooling jacket 1, and watercooling jacket 1 is made by corrosion-resistant metal materials, in watercooling jacket 1 two ends perforate, and one section welding water-in 5, other one section welding water outlet 6, water-in 5 and water outlet 6 are all made by general metal pipe material.
This casting slag device slag trough and watercooling jacket all process with straight carbon steel, and casting slag device 2, casting slag pit 4 are by mold casting forming.Slag trough 3 is a diameter 200mm semicircle camber, welds together with casting slag device 2, and casting slag device 2 is of a size of the rectangle of 400mm * 1200mm, the rectangle of its crosspiece face 50mm * 400mm; The radius of evenly distributed 10 row * 30 row is the dome-type casting slag pit 4 of 30mm in the casting slag device 2; The peripheral solder one circle watercooling jacket of casting slag device 2, the hole that it is 20mm that a diameter is respectively opened at the two ends of watercooling jacket 1 is with supporting weldless steel tube and water-in 5 and water outlet 6 welding of two diameters and aperture.
Utilize this metallurgical pre-melted slag casting slag device, but continuous high-efficient production granularity is the dome-type pre-melted slag of diameter 30mm, rhythm of production is controlled, and the production process no dust pollution has improved operating environment, has improved production efficiency.
