Abstract
A method for producing grinding ball and casting of nodular graphite cast iron features use of waste slag iron as raw material and includes smelting in cupola furnace and production in electric furnace. Its advantages are easy regulation of components, high desulfurizing effect and qualified rate of products, and low cost.
Description
The present invention relates to various ball mills, comprise grinding ore, coal dust, cement, particularly the ferrous metallurgy metal mine grinds the employed bainite ductile iron abrading-ball of ball mill of powdered iron ore and the production method of various mechanical ball milling ironcastings.
Produce bainite ductile iron abrading-ball and ball milling foundry goods at present both at home and abroad, have plenty of with cupola furnace and smelt the laggard capable spheroidizing of molten iron, be cast into abrading-ball or foundry goods again; Have plenty of with electrosmelting and go out molten iron, after spheroidizing, be cast into abrading-ball or foundry goods again, these two kinds of methods all have certain shortcoming, the former is to the ingredient requirement strictness, must be raw material with standard foundry iron (as casting 14), composition is wayward in manufacturing processed, and product percent of pass is low, and sweetening effectiveness is poor; Though latter's quality can be guaranteed, power consumption is many, the cost height.
The objective of the invention is to study a kind of with waste residue iron or blast-melted be the method for raw material production bainite ductile iron abrading-ball and foundry goods, require easy control of components in manufacturing processed, the product percent of pass height, sweetening effectiveness is good, cost is low.
Purpose of the present invention can realize by the following method:
Method one. with waste residue iron is raw material, smelts molten iron with cupola furnace, and desulfurization in hot metal ladle will be adjusted desulfurization once more after composition and the temperature in the molten iron impouring electric furnace after the desulfurization, carries out spheroidizing after reaching standard, is cast into abrading-ball or foundry goods then.
Method two. the molten iron that goes out with blast-furnace smelting is a raw material, and desulfurization in hot metal ladle is adjusted composition and temperature in the impouring electric furnace then, carries out desulfurization once more, carries out spheroidizing after reaching standard, is cast into abrading-ball or foundry goods then.
Advantage of the present invention is: producing according to method one, is raw material with waste residue iron, greatly reduces raw materials cost, convenient owing to adjust composition in electric furnace again, the product percent of pass height, and sweetening effectiveness is good; Produce according to method two, owing to be that blast-melted impouring electric furnace is produced, so economize on electricity, thus reduce production costs significantly, increase the business economic benefit.
Embodiment one, with waste residue iron is raw material: raw materials such as waste residue iron, Wingdale, coke, iron alloy are dropped in the cupola furnace smelt molten iron, in hot metal ladle, add sweetening agent, to carry out desulfurization in the molten iron impouring hot metal ladle in the cupola furnace then, claw scum silica frost, will adjust composition (adjusting carbon, silicon, manganese etc.) and temperature, desulfurization once more in the molten iron impouring electric furnace after the desulfurization again, carry out spheroidizing after reaching standard, be cast into abrading-ball or foundry goods then.
Embodiment two, with blast-melted is raw material: at first add sweetening agent in hot metal ladle, to carry out desulfurization in the blast-melted impouring hot metal ladle then, claw scum silica frost, afterwards with after adjusting composition (adjusting carbon, silicon, manganese etc.) and temperature in the molten iron impouring electric furnace, desulfurization is once more carried out spheroidizing after reaching standard, is cast into abrading-ball or foundry goods then.
Claims (2)
