Using magnesia castable refractory materials of copper smelting furnace

Using magnesia castable refractory materials of copper smelting furnace and reverberatory furnace, converter used in copper smelting, has the following advantages: damage delay smelting furnace, improves the service life of the whole lining, reduce maintenance costs, reduce labor intensity, to ensure the continuity of production.
Copper smelting converter lining the commonly used direct bonded magnesia chrome brick, semi bonded magnesia chrome brick, widely used in emission furnace lining is high quality magnesia bricks. Concentrated in the damaged area of the former on the feed material and the impact zone, the damaged area of the latter in the door on both sides and straight wall.
And when this site is damaged, the measure is shutdown, cooling down after the removal of refractory lining has been damaged and replaced with new refractory lining, resulting in not continuous production, affects the lining of other parts of the life, but also increase the energy consumption and the amount of labor.
The purpose of the golden bull refractory material is to make a kind of furnace can be used to produce the gap, in order to spray up the way to carry out the thermal state furnace repair refractory spray.
Using magnesia castable refractory copper smelting furnace Taurus production, according to the following steps: first of all kinds of raw materials according to the assigned production formula weighaccurately. Thin powder raw materials and additives were mixed with the double helix of V mixing machine.
The mixture by 750KG level roller mixer mixing. The sequence of the mixture: first add particles and stir for 5 minutes, then add the pre mixture for 10 minutes. The total mixing time is 15 to 20 minutes, the castable refractory material of each component is uniform.
It adopts a double-layer plastic woven bag, net weight of each bag is 500 + 5kg, or according to the supply and demand sides agreements., packaged products stored neatly stacked in the dry warehouse, and indicate the product name, brand, batch number, net weight, production date, production factory name and logo.
Using magnesia castable refractory material for copper smelting furnace refractory aggregate and the Taurus is a selection of fine powder, fused magnesia, sintered magnesia, calcined magnesite, talc, cordierite, forsterite, silicon carbide, critical particle size aggregate is 3mm, the size of fine powder is <0.088mm, the physicochemical index of various raw materials such as table shows:
Physical and chemical indexes of raw material for spraying and filling material
