Description
Technical field
The present invention relates to a kind of coating, relate in particular to a kind of repair paint of foundry furnace forehearth hot metal ladle, specifically be applicable to repairing foundry furnace forehearth hot metal ladle.
Background technology
Foundry furnace generally is used for the continuous casting of foundry goods, but because it can heat up the strong gap operation of ability, low, the good sealing effect of assembly expenses, thereby its not only castability is good, and casting efficient height is so obtained widespread use.But because foundry furnace is in hot environment for a long time; but also often contact with the casting liquation; thereby the situation of breaking appears in its local location regular meeting; at this moment, if foundry furnace is carried out integral replacing, not only cost is bigger; and complex operation; lose time, therefore, fracture site is repaired a kind of good selection of can yet be regarded as.
The Chinese patent publication number is CN101279854A, and the patent of invention that open day is on October 8th, 2008 discloses a kind of coil insulation safe furnace lining material, is 100% by total mass, and each component is a fused corundom 73～85%, aluminate cement 8～15%, Al
2O
3Micro mist 6～9%, bonding clay 1～3%, wherein the quality-class proportioning of fused corundom is: 1～3mm granularity fused corundom accounts for 18～22% of total mass ratio, and 0.044～1mm granularity fused corundom accounts for 35～43% of total mass ratio, and all the other are＜0.044mm granularity fused corundom.This invention also discloses the preparation method of above-mentioned furnace lining material, at first according to each group of aforementioned proportion weighing; Again with fused corundom, bonding clay and the Al of weighing
2O
3Micro mist is done to mix and is stirred, and obtains Preblend; In the last Preblend with load weighted aluminate cement adding gained again, do to mix and stir, add the water wet mixing again and stir into paste promptly.Though should invent refractoriness height, the good insulation preformance of related material, also can carry out sectional repair, but because it can only be used for the repairing of self, and can not be used to adopt the repairing of the foundry furnace that other material makes, thereby its range of application is narrower, and, its moiety price is more expensive, and production cost is higher, in addition, the repair efficiency of this invention is more coarse, toughness is lower, does not fit into the repairing to hot metal ladle.
Summary of the invention
The objective of the invention is to overcome the range of application that exists in the prior art is narrower, production cost is higher, repair efficiency is coarse, toughness is lower defective and problem, the repair paint of the foundry furnace forehearth hot metal ladle that a kind of range of application is wide, production cost is lower, repair efficiency is meticulous, toughness is higher is provided.
For realizing above purpose, technical solution of the present invention is: a kind of repair paint of foundry furnace forehearth hot metal ladle, and its moiety and weight part ratio thereof are: magnesia powder 10-20, black wood charcoal ash 70-80, hard charcoal ash 5-15, all the other are water.
Described system component and weight part ratio thereof are: magnesia powder 15, and black wood charcoal ash 75, hard charcoal ash 10, all the other are water.
Also comprise high alumina matter powder in the described coating, the mass percent that this high alumina matter powder accounts for coating is 5-10%.
The moiety of described black wood charcoal ash and weight part ratio thereof are: Graphite Powder 99 50-70, silica flour 20-40, diatomite 5-15.
The moiety of described black wood charcoal ash and weight part ratio thereof are: Graphite Powder 99 60, silica flour 30, diatomite 10.
Compared with prior art, beneficial effect of the present invention is:
1, because the moiety and the weight part ratio thereof of the repair paint of a kind of foundry furnace forehearth of the present invention hot metal ladle are: magnesia powder 10-20, black wood charcoal ash 70-80, hard charcoal ash 5-15, all the other are water, this design can improve refractoriness of the present invention and cohesiveness, especially the black wood charcoal ash can improve sophistication of the present invention, make its repair efficiency meticulousr, previous designs has enlarged range of application of the present invention, make it not be subjected to the restriction of the former materials used of foundry furnace, and then be convenient to the fracture site on the various foundry furnaces is repaired, be particularly useful for repairing to foundry furnace forehearth hot metal ladle.Therefore not only repair efficiency is meticulous in the present invention, and range of application is wider.
2, because the main raw material(s) of the repair paint of a kind of foundry furnace forehearth of the present invention hot metal ladle is magnesia powder, black wood charcoal ash, hard charcoal ash and water, those material ratios are easier to obtain, and it is cheap, even the preferred material in black wood charcoal ash and the coating, as Graphite Powder 99, silica flour, diatomite, high alumina matter powder etc., also all be cheap starting material, not only can reduce production costs, and Graphite Powder 99, silica flour, diatomite can strengthen the fine and smooth effect of repairing, high alumina matter powder can improve repairing physical strength, strengthen toughness.Therefore not only production cost is lower, range of application is wider in the present invention, and repair efficiency is meticulous, toughness is higher.
