Description
Technical field
The present invention relates to casting technology field, specially a kind of wear-resisting ironware material and smelting process.
Background technology
Cast iron belongs to secondary operation, the part of complexity is can be made into, with excellent castability, machinability, wearability
And absorb shock resistance, it is the important primary product of Metallurgical Factory, is mostly used in steel-making, another part supply and its manufactory's production casting
Ironware, as the main furnace charge of secondary remelting, 60~70% weight is ironcasting in modern machines equipment.The lastness of cast iron
Can be influenced by many factors, such as：The composition and proportioning of raw materials for metallurgy, the control of temperature when smelting, raw material is added when smelting
Temperature-time, the Post isothermal treatment of casting when pouring of order, the use of inovulant, molten iron etc., each factor is required to very
Note just can guarantee that the mechanicalness of iron casting.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of wear-resisting ironware material and smelting process, to solve above-mentioned background
The problem of being proposed in technology.
To realize above-mentioned technical purpose and the technique effect, the present invention is achieved through the following technical solutions：
A kind of wear-resisting ironware material, is made up of the parts by weight of following raw materials according：
Iron：75-85, carbon：8-10, copper：12-16, silicon：3-8, manganese：4-6, chromium：5-8.
A kind of smelting process of wear-resisting ironware material, according to following smelting process：
(1) slag former is piled in furnace bottom；
(2) continuously add scrap iron and begin heat to scrap iron dissolving；
(3) desulfurizing dephosphorizing agent is added, scrap iron is continuously added, when remaining a certain amount of, stops adding scrap iron；
(4) be initially added into ferrochrome to it is remaining a certain amount of when, stop add ferrochrome, remaining steel scrap is added, then by chromium
Iron is all added；
(5) when furnace temperature rises to 1600~1700 degrees Celsius, waste residue is removed, ferromanganese, molybdenum-iron, vanadium iron, electrolysis is then added
Copper, ferronickel, ferro-boron, ferrotianium；
(6) when furnace temperature rises to more than 1700 degrees Celsius, ferrosilicon deoxidation is added, waste residue is then removed again；
(7) inovulant is added in ladle, molten iron, which is come out of the stove, is transported to ladle, continues to remove waste residue；
(8) cast when molten iron temperature is at 1500~1550 degrees Celsius.
The beneficial effects of the present invention are：The ironware casting technique, it is former by the design of rational composition proportion and step
Material and mould can be reused, and production efficiency is high, can be realized recycling for scrap iron and waste casting, be saved casting material
Material, reduces production cost, effectively increases the outward appearance and inherent quality of casting.
