Abstract
A composite temperature elevating agent pelletizing is provided, wherein, the inside of a pellet body is provided with silicon, quartz sands, silicon dioxide and carbon, and the above ingredients are combined of silicon slag, scaffold material, and roasting materials, silicon iron slag and other industrial wastes of a graphite electrode plant through adhesive. The utility model can replace part of ferrosilicon and carburant, so warming, deoxidizing and carburizing can be finished at one time. The utility model has the advantages of low production cost, low pollution, effective improvement of steel quality, and reduction of steel production cost.
Description
Technical field:
The utility model belongs to metallurgical technology field, be used in the steelmaking process to heat, pelletizing that carburetting and deoxidation are used.
Background technology:
Steel-making at present heat the deoxidation traditional technology, mainly use ferrosilicon, but ferrosilicon production per ton needs power consumption to reach about 10000 degree, price is higher, influences the total cost of steel.
Summary of the invention:
The purpose of this utility model is to provide a kind of compound heating agent pelletizing, can realize heating, the effect of deoxidation and carburetting, and production cost is low.
The utility model is realized in the following way:
This compound heating agent pelletizing comprises a spheroid (1), wherein: also have silicon (2), quartz sand (3), silicon-dioxide (4) and carbon (5) in spheroid (1).
Described spheroid (1) is made up of various industrial wastes such as the roasting material of white residue, furnace burdening, graphite electrode plant and ferro-silicon slags.
Described various particle is by silicate or the silication wedding agent is bonding forms.
The intensity of pelletizing is greater than 2000 a newton/ball.
The utility model compared with prior art has following advantage:
The utility model adopts silicon, quartz sand, the pelletizing that silicon-dioxide and carbon are formed, alternative part ferrosilicon and carburelant, make and heat, deoxidation and carburetting are once finished, after adding molten steel, do not blown damage, do not play naked light, the utilization ratio height, improve former technology and added various powder system deoxidations, the scaling loss that carburelant in use causes and to the pollution of environment, simultaneously since the gravity of pelletizing sink in the molten steel, from furnace bottom progressively levitating produce carbon monoxide, work the molten steel effect of stirring, can improve steel product quality effectively, simultaneously a large amount of industrial wastes be turned waste into wealth, reduce the production cost of steel greatly.
Description of drawings:
Fig. 1 is the utility model structure iron.
In Fig. 1: (1) spheroid; (2) silicon; (3) quartz sand; (4) silicon-dioxide; (5) carbon.
Embodiment:
The granularity of this pelletizing is 60 * 45 * 30mm, composition: silicon 40～53%; Carbon 10～40%; Metallic aluminium＜1.5%; Sulphur＜0.1%; Phosphorus＜0.1%; Uncombined carbon＜7%; Moisture content＜1%.Above silicon. carbon content can be according to the customer requirements adjustment.Manufacture craft: various raw materials and tackiness agent → mixing → stirring → system ball → oven dry → finished product → pack → indicated weight → stacking.
Claims (4)
1, a kind of compound heating agent pelletizing comprises a spheroid (1), it is characterized in that: also have silicon (2), quartz sand (3), silicon-dioxide (4) and carbon (5) in spheroid (1).
2, pelletizing according to claim 1 is characterized in that: described spheroid (1) is that various industrial wastes such as the roasting material of white residue, furnace burdening, graphite electrode plant and ferro-silicon slag are formed.
