Description
Technical field
The invention belongs to copper alloy technical field of smelting, relate to tin bronze melting slag former and using method thereof, particularly a kind of slag former that can reduce tin bronze fusion process copper loss and using method thereof。
Background technology
Copper is the non-ferrous metal very close with human relation, be widely used in electrically, light industry, machine-building, building, the field such as national defence。In numerous copper alloy products, tin bronze, owing to having minimum shrinkage coefficient, is commonly used to produce complex-shaped, clear-cut, the less demanding foundry goods of air-tightness。Additionally, due to it is abnormal corrosion-resistant in air, sea water, fresh water and steam, it is widely used in the high request foundry goods such as steam boiler, seagoing vessel part, valve instrument。
China began to manufacture bronze as far back as the period of the Warring States, have accumulated abundant melting experience。But, owing to tin bronze needs higher smelting temperature, the Cu oxide that the high temperature at fusion process results in swims in copper fusant surface in liquid form and goes out of use together with waste residue condensation。Therefore, in tin bronze fusion process, for reducing copper oxide content in slag, reduce copper oxide in process of skimming to be pulled away, copper loss is reduced when quickly skimming, research and development tin bronze melting slag former and using method thereof, to reduce copper content in slag, have important practical significance to the development of tin bronze industry。
Summary of the invention
The present invention is directed to the technical problem of above-mentioned existence, it is provided that a kind of slag former reducing copper content in tin bronze smelting slag and using method thereof。
For achieving the above object, technical scheme is as follows:
Tin bronze melting slag former, including copper reduction slag former and Slag conglomeration agent, the copper reduction slag former being made up of the glass dust of the charcoal powder of 3～10% weight, 90～97% weight, is formed Slag conglomeration agent by crushed crude pearlite。
Described glass dust consists of: SiO2Content 71 ~ 75% weight, Na2O content 10.5 ~ 13% weight, CaO content 9 ~ 12% weight, content of MgO 0.5 ~ 3.0% weight, Al2O3Content 0.5 ~ 2.0% weight, K2O content 0.1 ~ 0.3% weight, < 1% weight, surplus is impurity to water content；
Described crushed crude pearlite consists of: SiO2Content 68 ~ 74% weight, Al2O3Content 10 ~ 14% weight, Na2O content 4 ~ 5% weight, K2O content 2 ~ 3% weight, CaO content 0.7 ~ 1% weight, Fe2O3Content 0.5 ~ 3.6% weight, content of MgO 0.1 ~ 0.5% weight, < 4% weight, surplus is impurity to water content；
Described charcoal powder fixed carbon content is 40～60% weight, and granularity is 40～60 orders。
Described glass powder particles granularity 40 order ~ 80 order (containing) it is 95%, 10 order ~ 40 orders are 5%；Described crushed crude pearlite grain graininess 35 order ~ 80 order (containing) it is 80%, 10 order ~ 35 orders are 20%。
Using method is: in smelting tin bronze alloy process, after molten alloyed copper components tests is qualified, control copper liquid temperature at 1150 ~ 1250 DEG C, it is initially charged the glass dust containing charcoal powder and makes reduction slag former, addition is the 0.01 ~ 0.1% of molten alloyed copper weight, after molten alloyed copper is stirred, add crushed crude pearlite and make Slag conglomeration agent, addition is 0.01 ~ .0.2% of molten alloyed copper weight, gentle agitation is uniform again, after making the scum silica frost thing above molten alloyed copper be gathered into rapidly big bulk, with skimming, block is skimmed by spoon。
Compared with prior art, it is an advantage of the current invention that: the present invention adopts abundant raw material, low-cost charcoal powder, glass dust and perlite to be slag former and Slag conglomeration agent, first in slag former, add a small amount of charcoal powder, for high temperature furnace is gone back the oxide of native copper, reduce the content of copper oxide and Red copper oxide in slag, add crushed crude pearlite Slag conglomeration agent, improve perlitic poly-slag effect, also solve the problem that in the slag being simultaneously introduced glass dust and crushed crude pearlite, copper content is high。Compared with prior art reduce in slag more than the 40% of copper content, the copper rate of tin bronze melting is greatly improved, there is good economic benefit。
