Description
Technical field
The utility model relates to the Ferrous Metallurgy field, especially relates to a kind of the carbon containing pulverulent material being made the adding pressure type ball press of orbicule, and this carbonaceous pelletizing is mainly used in smelting iron and steel and uses.
Background technology
Carbonaceous pelletizing is exactly to contain certain carbon element in the pelletizing as its name suggests, as contains coke, coal, graphitic carbon, charcoal etc.In the Ferrous Metallurgy field, in different technology, requirement for a certain metallurgical technology, adopt different carbonaceous pelletizings, but common metallurgy carbonaceous pelletizing, its phosphorus content is all lower, generally be no more than 30%, as be used to produce the pelletizing of sponge iron, and phosphorus content is 10-20% usually, its effect is that carbon uses as reducing agent in whole process of production; Used iron content agglomerates of sintered pellets in blast furnace or shaft furnace production process generally is equipped with 5% coke blacking, when carbon element wherein is burning as the usefulness of exothermic mixture, binding agent.
In addition, the primary raw material of electric furnace steel making or cast steel is a steel scrap, comprises the discarded steel of non-structural part or non-bearing part, and these all are frivolous steel scraps, its phosphorus content is all lower, general carbon content and because standing time is long, is placed in the open between 0.15-0.35% usually, steel scrap very easily gets rusty, when making steel in electric furnace with this steel scrap, the carbon content according to smelting steel grade need be equipped with carbon element in furnace charge.When being equipped with carbon element, because the scaling loss of needs consideration carbon and a part of carbon also will participate in the reduction reaction to iron oxide, so need add higher carbon amount.The material of joining carbon usually has pig, molten iron, block coke, barren rock electrode ink or carbonaceous pelletizing, and the carbonaceous material etc. that sprays powdery in molten steel.Join in the carbon material above-mentioned, carbonaceous pelletizing since produce easy, inexpensive and easy to use, be electric furnace steel making the most frequently used join one of carbon material, promptly be the furnace refractory of using always.
In the prior art, the most frequently used carbonaceous pelletizing of electric furnace steel making is to be primary raw material with the coke blacking, is equipped with a certain amount of binding agent and makes, and its phosphorus content reaches more than 80%.Produce this kind carbonaceous pelletizing and have two to rolling over the roller ball pressuring machines that roll of milling roller in main employing at present.Active milling roller and passive milling roller that this rolls driving gear that roller ball pressuring machine comprises that actuating unit drives and driven gear, is driven by driving gear and driven gear, initiatively have symmetrically arranged hemispheric depression on milling roller and the passive milling roller, form two pressure hemisphere.Material enters from hopper, and the material that enters two pressure hemisphere compresses between two major-minor milling rollers, forms spheroid.
This kind rolls roller ball pressuring machine in actual use, when various powders are pressed into spheroid, because its pressure is subjected to condition restriction, air in the material can't be discharged, very big to pressure, density, the intensity effect that will increase balling-up, especially the material balling-up to looser, that viscosity is very little is very difficult, not even balling-up, therefore, caused and rely on adhesive to guarantee the intensity of product to a great extent.
There is deficiency in the prior art in order to overcome, a kind of adding pressure type ball press has been proposed at present, as shown in Figure 1, active milling roller 2 and passive milling roller 3 that this adding pressure type ball press comprises driving gear that actuating unit drives and driven gear, driven by driving gear and driven gear, install two pinions on driving gear and driven gear additional, corresponding initiatively milling roller and passive milling roller are provided with two secondary milling rollers 6 of pressing that driven by two pinions in material.After installing two secondary pressure milling rollers 6 additional, material divides three the tunnel to advance, the material that enters from both sides compresses between two major-minor milling rollers, form two pressure hemisphere, the air of having drained, along with the continuation rotation of active milling roller 2 and passive milling roller 3, between active milling roller 2 and passive milling roller 3, carry out the pressurization second time again.Pressurization excludes air in the material to this adding pressure type ball press to material, and then extrusion forming, and the outward appearance of molding materials is good, density is big, pressure is high, intensity increases.
But this adding pressure type ball press has increased by two pinions and corresponding transmission mechanism, cause its complex structure, and its production efficiency does not improve.
Summary of the invention
