Abstract
The invention relates to a method for producing a multicomponent alloy from coal gangues and various solid wastes. The method is characterized in that reasonable ratios of contents of various elements are determined by adding other industrial wastes into the coal gangues containing main components of Al2O3 and SiO2 and further containing Fe2O3, CaO, MgO, Na2O, K2O, P2O5, SO3 and trace rare elements (gallium, vanadium, titanium and cobalt) that have different amounts, and the coal gangues replace such raw materials as silica and steel cuttings necessary for producing the conventional multicomponent alloy. According to the method, several wastes are thermally mixed and melted in a refining furnace by using beneficial elements in waste slag and waste powder that are produced during smelting production of silicon iron under heat of molten iron in a submerged arc furnace, so that a multicomponent alloy product meeting the requirements of a user is produced. By the use of the method for producing the multicomponent alloy, 0.01 to 0.015 ton of the coal gangues can produce one tonnage of products, so that the power consumption can be reduced by 2,000 to 3,500, 12,498.5 ton of standard coals can be saved every year, and 16,000 ton of each type of waste slag/powder can be handled. According to the method, the production cost is reduced, resources are saved, and the additional value of a product is increased; therefore, a large amount of industrial waste slag can be comprehensively used, and the aims of saving energy and reducing consumption are fulfilled.

Ton mark coal, produces multicomponent alloy 20000 tons calculating, 7400 tons of feast-brand mark coal mark coal per year with this enterprise.Semi-coke consumption is reduced by the method
0.6 ton, conversion 9600 tons of coal of mark, adding up to saving mark coal is 17000 tons of mark coals, disposes every waste residue powder 16000 tons.
A kind of production procedure utilizing gangue and various solid wastes to produce multicomponent alloy
Before production, answer ready work, it is ensured that device security can be good, possess entry condition.
Gangue, garbage are processed, wears into powdery, and raw material is sampled chemical examination.
A certain amount of garbage powder is put into the feeding system researched and developed voluntarily in proportion.
Raw material is sent into sintering in bulk in mineral hot furnace by conveyer belt by feeder, forms the primary raw material producing ferroalloy
Multiple elements design material.
Multiple elements design material is sampled analysis ingredient.
The molten iron utilizing mineral hot furnace ensures that refining furnace furnace temperature reaches fusible state, adds the refuses such as a certain amount of mountain Pi Shi and exists
In stove, heat converts thawing.
After converting fusing by heat, aluminium alloy is poured in ingot mould and cool down；Broken and sampling Detection is carried out after cooling；Detection is closed
Lattice product, carry out graded crushing packaging according to the size of customer requirement.
After production completes, carry out cleaning in stove, and the trouble free service such as the equipment that checks is the most intact.
Products application systematic function
(1) ferroalloy is typically used as deoxidizer.Removing the oxygen in molten steel in steelmaking process, some ferroalloy also can remove in steel
Other impurity such as sulfur, nitrogen etc..
(2) multicomponent alloy is used as alloy addition.By steel grades requirement, add alloying element interior to improve steel to steel
Performance.
(3) multicomponent alloy is used as inovulant, adds in molten iron, improve the crystalline structure of foundry goods before cast iron casting.
Compared with traditional technology, the present invention has a following feature:
(1) the traditional mode of production raw material of this product is mainly Silicon stone, coke, steel cuttings etc., the metallic element in smelting reduction raw material, shape
Become ferrosilicon.In process of production, use electric energy to be converted to heat energy, cause power consumption big, meanwhile, the response rate of element in raw material
Low, cause the waste of resource and the pollution of environment.
(2) my company's independent research, has carried out the technical study utilizing trade waste for raw material production multicomponent alloy.Warp
Cross rational proportioning, extract the beneficial element that waste residue gives up in powder, make beneficial element be reduced, improve the response rate, reject miscellaneous
Matter, needed for Foundry Production, produces multiple multicomponent alloy, it is achieved that the comprehensive utilization of waste resource, reduces production cost,
Advance energy-saving and emission-reduction work.
