Abstract
The invention discloses a coating for repairing a foundry furnace lining surface. The coating comprises the following components in part by weight: 10 to 30 parts of fireproof clay, 60 to 70 parts of coke powder, 5 to 15 parts of black carbon ash, 4 to 6 parts of white carbon ash and the balance of water, wherein the fireproof clay comprises the following components in part by weight: 50 to 70 parts of bentonite, 20 to 40 parts of silica sand and 5 to 15 parts of kaolin; and the granularity of the coke powder is 15 millimeters, and the coke powder comprises 5 mass percent of talcpowder. The coating has the advantages of good repair effect, wide application range and low production cost.
Description
Technical field
The present invention relates to a kind of coating, relate in particular to a kind of coating that is used to repair foundry furnace furnace lining surface, specifically be applicable to repairing foundry furnace furnace lining surface.
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.
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 defective and problem, provide that a kind of range of application is wide, the coating on foundry furnace furnace lining surface is repaired in lower being used to of production cost.
For realizing above purpose, technical solution of the present invention is: a kind of coating that is used to repair foundry furnace furnace lining surface, and its moiety and weight part ratio thereof are: refractory mortar 10-30, coke powder 60-70, black wood charcoal ash 5-15, hard charcoal ash 4-6, all the other are water.
Described system component and weight part ratio thereof are: refractory mortar 20, and coke powder 65, black wood charcoal ash 10, hard charcoal ash 5, all the other are water.
The moiety of described refractory mortar and weight part ratio thereof are: wilkinite 50-70, silica sand 20-40,5-15 on the high mountain range.
The moiety of described refractory mortar and weight part ratio thereof are: wilkinite 60, silica sand 30, kaolin 10.
The globule size of described coke powder is 15mm, and it comprises that mass percent is 5% talcum powder.
Compared with prior art, beneficial effect of the present invention is:
1, since a kind of coating moiety and weight part ratio thereof that is used to repair foundry furnace furnace lining surface of the present invention be: refractory mortar 10-30, coke powder 60-70, black wood charcoal ash 5-15, hard charcoal ash 4-6, all the other are water, this design can improve refractoriness of the present invention and cohesiveness, thereby enlarge range of application of the present invention, make its restriction that is not subjected to the former materials used of foundry furnace, and then be convenient to the fracture site on the foundry furnace is repaired, be particularly useful for repairing foundry furnace furnace lining surface.Therefore range of application of the present invention is wider.
2, because a kind of main raw material(s) that is used to repair the coating on foundry furnace furnace lining surface of the present invention is refractory mortar, coke 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 refractory mortar and the coke powder, as wilkinite, silica sand, kaolin, talcum powder etc., also all be cheap starting material.Therefore not only production cost is lower in the present invention, and range of application is wider.
