The black charcoal ash comprises the following components in percentage by weight: 60% of graphite powder, 30% of alundum powder and 10% of explosion-proof fiber; and the fineness of the black charcoal ash is 100-200 meshes. The coating provided by the invention not only has the advantages of low production cost, wide application range, fine repairing effect and high toughness.
Description
Technical field
The present invention relates to a kind of coating, relate in particular to a kind of coating for repairing the front furnace of casting furnace ladle, specifically be applicable to the repairing to the front furnace of casting furnace ladle.
Background technology
Foundry furnace generally is used for the continuous casting of foundry goods, but strong gap operation of ability because it can heat up, assembly expenses are low, good sealing effect, thus its not only castability is good, and casting efficient is high, so be widely applied.But because foundry furnace is in hot environment for a long time; but also often contact with the casting liquation; thereby its local location often the situation of breaking can occur; at this moment, if foundry furnace is carried out integral replacing, not only cost is larger; and complex operation; lose time, therefore, fracture site is repaired a kind of good selection of can yet be regarded as.
China Patent Publication No. 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 gross mass, and each component is electro-corundum 73～85%, aluminate cement 8～15%, Al
2O
3Micro mist 6～9%, bonding clay 1～3%, wherein the quality-class proportioning of electro-corundum is: 1～3mm granularity electro-corundum accounts for 18～22% of total mass ratio, and 0.044～1mm granularity electro-corundum accounts for 35～43% of total mass ratio, and all the other are＜0.044mm granularity electro-corundum.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 electro-corundum, bonding clay and the Al of weighing
2O
3Micro mist is dry mixed stirring, obtains premix; Last more load weighted aluminate cement is added in the premix of gained, be dry mixed stirring, add again the water wet mixing and stir into paste and get final product.The refractoriness of related material was high, good insulation preformance although should invent, also can carry out sectional repair, but because it can only be used for the repairing of self, and can not be used for the repairing of the foundry furnace of other material manufacturing of employing, thereby its range of application is narrower, and, its constituent price is more expensive, and production cost is higher, in addition, the repair efficiency of this invention is more coarse, toughness is lower, is not suitable for the repairing to 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 coating that is used for repairing the front furnace of casting furnace 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 coating for repairing the front furnace of casting furnace ladle, and its constituent and weight ratio thereof are: fire clay 2-8, black wood charcoal ash 85-95, hard charcoal ash 3-7, all the other are water.
The constituent of described coating and weight ratio thereof are: fire clay 5, and black wood charcoal ash 90, hard charcoal ash 5, all the other are water.
Also comprise stainless steel fibre in the described coating, the mass percent that this stainless steel fibre accounts for coating is 5-10%.
The constituent of described black wood charcoal ash and weight ratio thereof are: graphite powder 50-70, schmigel 20-40, explosion-proof fiber 5-15.
The constituent of described black wood charcoal ash and weight ratio thereof are: graphite powder 60, schmigel 30, explosion-proof fiber 10.
The fineness of described black wood charcoal ash is the 100-200 order.
Compared with prior art, beneficial effect of the present invention is:
1, because constituent and the weight ratio thereof of a kind of coating for repairing the front furnace of casting furnace ladle of the present invention are: fire clay 2-8, black wood charcoal ash 85-95, hard charcoal ash 3-7, all the other are water, this design can improve refractoriness of the present invention and caking property, 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 use material of foundry furnace, and then be convenient to the fracture site on the various foundry furnaces is repaired, be particularly useful for the repairing to the front furnace of casting furnace ladle.Therefore not only repair efficiency is meticulous in the present invention, and range of application is wider.
2, the main raw material(s) owing to a kind of coating for repairing the front furnace of casting furnace ladle of the present invention is fire clay, black wood charcoal ash, hard charcoal is grey and water, those material ratios are easier to obtain, and cheap, even the preferred material in black wood charcoal ash and the coating, such as graphite powder, schmigel, explosion-proof fiber, stainless steel fibre etc., also all be cheap raw material, not only can reduce production costs, and graphite powder, schmigel, explosion-proof fiber can strengthen the fine and smooth effect of repairing, stainless steel fibre can improve repairing mechanical 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.
