Abstract
The invention relates to the improved technique of the metal smelting equipment, in particular to a ramming mass special for a hearth of a copper refining reverberatory furnace. The ramming mass is characterized by comprising the following components by weight percentage: 50% of magnesium powder, 20% of iron powder, 4.5% of iron oxide red, 20% of magnesia chromite steel fibre casting compound and 5.5% of brine. The ramming mass overcomes the shortcomings of poor compactibility, loose structure after maintenance, easy permeation of liquid copper, short service life, high maintenance and the like of the traditional ramming mass, and is mainly used as a protection layer on the hearth of the copper refining reverberatory furnace.
Description
(1) technical field: the present invention relates to the improvement technology of metal melting equipment, the special-purpose ramming mass of especially a kind of Copper Refining Reverberatory Furnace furnace bottom.
The (2) background technology: Copper Refining Reverberatory Furnace is that copper is smelted one of visual plant of processing, is to suppress the destruction of high temperature copper water to reverberatory furnace furnace bottom antiarch masonry, must be at the auxilliary ramming bed of material of establishing of reverberatory furnace furnace bottom; The tradition ramming mass is to adopt magnesium powder, iron powder, bittern formulated, and this ramming mass formability is relatively poor, short texture after the maintenance; By the infiltration of copper water, cause ramming bed of material copper content to increase sharply easily, forfeiture heat-insulation and heat-preservation ability and the ability that absorbs reinforced shock action; General Copper Refining Reverberatory Furnace furnace bottom will damage half a year; Need build by laying bricks or stones again, maintenance cost is high, and the maintenance that need stop production simultaneously has a strong impact on the turnout of manufacturer.
The (3) summary of the invention: the object of the invention will solve traditional ramming mass insufficient formability exactly, short texture after the maintenance, and easily by the infiltration of copper water, the problem that work-ing life is short provides a kind of high-performance Copper Refining Reverberatory Furnace furnace bottom special-purpose ramming mass.
Concrete scheme of the present invention is: improve to traditional ramming mass, it is characterized in that: its weight percentages is: magnesium powder 50%, iron powder 20%, iron oxide red 4.5%, magnesium chromium matter steel fiber casting material 20%, bittern 5.5%.
The present invention is under reverberatory furnace high-temperature service condition, owing to allocated red iron oxide in the ramming mass, its chemical property is active, interacts with Natural manganese dioxide, helps magnesian sintering diffusion; Impel the periclasite crystallization to grow; Simultaneously the iron ion diffusibility is strong, can form the continuous crystallisation web frame, makes ramming bed of material compact structure.
In ramming mass, allocated the steel fiber casting material among the present invention into, can strengthen the ramming mass structural strength, when reverberatory furnace heated up, steel fiber can become the volatilization passage of moisture, plays explosion-proof effect, prevents that the structure of the ramming bed of material from being destroyed by steam simultaneously.
Ramming mass of the present invention has following characteristics: good moldability, compact structure after the maintenance, there is not pore, and be not easy to have been protected the furnace bottom of Copper Refining Reverberatory Furnace admirably by the infiltration of copper water, compare traditional ramming bed of material work-ing life and can improve more than three times.
The (4) embodiment:
Get 50 kilograms in magnesium powder, 20 kilograms of iron powders, 4.5 kilograms of iron oxide reds, 20 kilograms of magnesium chromium matter steel fiber casting materials, 5.5 kilograms in bittern, the batching back adopts mechanical stirring even, and caking phenomenon must not be arranged, and forbids to bring into impurity, moisture.Ramming mass prepares in back 1 hour and uses up, and is used for the furnace bottom ramming bed of material as taking place harden, and natural curing got final product in 48 hours.Its intensity is much better than traditional ramming mass.Specimen surface is fine and close; There is not pore; On-the-spot result of use is fine, and the blow-on of refining reverberatory furnace was produced after one month, and the temperature that records ramming bed of material below effectively is controlled at 140-180 ℃; And the reverberatory furnace ramming bed of material below temperature that adopts traditional ramming mass is up to 280-330 ℃, so the ramming bed of material of the present invention protection life of bottom can improve more than three times.
Claims (1)
1. the special-purpose ramming mass of a Copper Refining Reverberatory Furnace furnace bottom, it is characterized in that: its weight percentages is: magnesium powder 50%, iron powder 20%, iron oxide red 4.5%, magnesium chromium matter steel fiber casting material 20%, bittern 5.5%.
