Abstract
The invention discloses a kind of high carbon ferro-chrome composition and its smelting process, the high carbon ferro-chrome includes following component: chromite powder, amargosite, manganese metal, dolomite dust, ferro-boron, nickel powder, quartzite and magnesium.The invention has the beneficial effects that: simple process, product cost is low, is easily obtained, and slag utilization rate is high, reduces the pollution to environment, saves power consumption, improves the rate of recovery of chromium.
Description
Technical field
The present invention relates to high carbon ferro-chromes to produce preparation field, and in particular to a kind of high carbon ferro-chrome composition and its smelting side
Method.
Background technique
Ferrochrome is the most important raw material for producing stainless steel, is mainly used in production stainless steel, ball-bearing steel, tool
Steel, nitrided steel, refractory steel, quenched and tempered steel, carburizing steel and hydrogen resistant steel, this is because chromium playing a decisive role in stainless steel, determines
The element of stainless steel attribute only has one kind, and here it is chromium, a certain number of chromium are centainly contained in every kind of stainless steel capital.High carbon ferro-chrome
Smelting process has blast furnace process, electric furnace process, plasma oven process etc..It can only be made using blast furnace and obtain extraordinary life 30% or so containing chromium
Iron.The high high carbon ferro-chrome containing chromium mostly uses flux method to smelt in mineral hot furnace.
Summary of the invention
The object of the present invention is to provide a kind of high carbon ferro-chrome composition and its smelting process, the high carbon ferro-chrome include with
Lower ingredient: chromite powder, amargosite, manganese metal, dolomite dust, ferro-boron, nickel powder, quartzite and magnesium；By following weight percent
Raw material be made:
It is further preferred that the high carbon ferro-chrome includes following component: chromite powder, amargosite, manganese metal, dolomite
Powder, ferro-boron, nickel powder, quartzite and magnesium；It is made of the raw material of following weight percent:
The high carbon ferro-chrome the following steps are included:
(1) raw material is prepared according to above-mentioned each weight percent；
(2) above-mentioned raw materials ground, sieved, mixed；
(3) mixed raw material is put into electric furnace and is smelted, the smelting temperature is 1500 DEG C~1650 DEG C；
(4) duration of heat control is in 3h-4h.
The invention has the beneficial effects that: simple process, product cost is low, is easily obtained, and slag utilization rate is high, reduction pair
The pollution of environment saves power consumption, improves the rate of recovery of chromium.
