The embodiment provides an aluminum carbon drainage opening waste repairing mass which comprises the following components in percentage by weight: 43-53 parts of aluminum carbon drainage port waste, 30-40 parts of magnesia and 1-7 parts of a binder.
At present, after the aluminum carbon sewer inlet of a domestic medium-large steel mill is used, except that waste steel adhered to the aluminum carbon sewer inlet is recycled, the aluminum carbon sewer inlet is basically discarded and buried or used for extremely low-grade repair, so that the environment is polluted, and resources are seriously wasted. The invention can obviously improve the utilization rate of resources, fully realize the secondary utilization of the resources and reduce the resource waste and the energy consumption. In addition, this embodiment is used for making the mending material with the mouth of a river waste material under the aluminium carbon, and low cost is showing the manufacturing cost who has reduced the enterprise, effectively improves product price/performance ratio and market competition.
Sintering refers to that raw materials are combined into blocks with stable chemical components and physical properties by means of high temperature and a series of physical and chemical changes, so that the requirement of the repairing mass is met. In this embodiment, since the carbon content in the aluminum carbon nozzle scrap is high, which is not beneficial to sintering, the sintering degree of the raw material is improved by adding the sintering aid.
The aluminum carbon drain scrap repairing mass provided by the embodiment comprises 10-20 parts of aluminum carbon drain scrap with the granularity of 5-8 mm, 13-23 parts of aluminum carbon drain scrap with the granularity of 3-5 mm and 10-20 parts of aluminum carbon drain scrap with the granularity of 1-3 mm.
In the repairing mass of the aluminum carbon drain pipe waste material provided by this embodiment, the magnesite is preferably fused magnesite with a particle size not greater than 1 mm. The fused magnesia with the granularity not more than 1mm is used, so that the sintering quality and the fluidity of the material can be optimized, and the bonding strength and the compressive and flexural strength of the repairing mass are improved.
The aluminum carbon collector nozzle waste repairing mass preferably further comprises a combustion improver, wherein the combustion improver is diesel oil, and the diesel oil accounts for 1-6 parts by weight. The diesel oil has the combustion-supporting function when the raw materials are sintered.
The aluminum carbon collector nozzle scrap repairing mass provided by the embodiment is further added with 1-7 parts by weight of resin. The resin can fully bond the sintering particles, so that a sintering body with high strength and uniform structure can be obtained after sintering.
In order to improve the flow fluidity, the aluminum carbon collector nozzle scrap repairing material provided by the embodiment can be added with asphalt, wherein the granularity of the asphalt is not more than 3mm, and the weight of the asphalt is 7-17 parts. The asphalt is added to further improve the flowing property of the repairing mass, so that the repairing mass flows to the area to be repaired uniformly, and the repairing mass is sintered more uniformly.
Further, the aluminum carbon collector nozzle scrap repairing mass provided by the embodiment may further be added with an additive, preferably aluminum. Because carbon is easy to oxidize at high temperature, the metal aluminum powder is added as an antioxidant, and the oxidation resistance is carried out while sintering raw materials, so that the sintered block has higher strength and more uniform structure.
In the aluminum carbon collector nozzle scrap repairing material provided by this embodiment, the binder may be at least one selected from iron powder, silicon powder and titanium fine powder. Preferably, the auxiliary binder can be iron powder and titanium fine powder, and the weight ratio of the iron powder to the titanium fine powder is 2: 1-5: 1. The auxiliary caking agent can also be silicon powder and aluminum powder, and the weight ratio range of the silicon powder to the aluminum powder is 2: 1-5: 1.
In this embodiment, since the carbon content in the aluminum carbon nozzle scrap is high, which is not beneficial to sintering, the sintering degree of the raw material is improved by adding the sintering aid.
