Abstract
The utility model relates to a casting pipe for copper alloy continuous casting, belonging to the field of spare parts for alloy continuous casting. The casting pipe comprises a graphite casting pipe. A first refractory mortar layer is arranged at the external part of the graphite casting pipe. The thickness of the first refractory mortar layer is 3-10mm. Since the refractory mortar layer is arranged at the external part of the graphite casting pipe, the graphite casting pipe can be prevented from being directly exposed in the air, the service life of the graphite casting pipe is effectively improved, the service life of the casting pipe with the refractory mortar layer at the external part is commonly approximate 100 hours according to practical use, the casting pipe is simple to manufacture, the cost is low, the casting pipe is convenient to use, the equipment cost can be effectively reduced if the casting pipe is used during copper smelting and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of cast tubes, and particularly a kind of continuously casting copper alloy gate spool belongs to the alloy continuous casting and uses the spare part field.
Background technology
Copper alloy is when the melting continuous casting, the molten metal high-temp liquid to be poured into the graphite cast tubes, the temperature of copper alloy metal liquid is about 1180 degree, though graphite has higher resistance to elevated temperatures, but it is still easily oxidized and destroy under this hot environment, service life is very short, according to statistics, the average life span that this graphite cast tubes is used under copper alloy liquid casting environment was at 7-8 hour, this has not only increased the spare part cost of smelting process, and caused the frequent pause of producing, have a strong impact on productivity ratio, also can produce hidden danger of quality and the potential safety hazard of higher probability too short service life, is unfavorable for high efficiency process capability expansion, needs a kind of life-span long in the production practices, stay-in-grade continuously casting copper alloy gate spool.
Summary of the invention
This use is novel for a kind of continuously casting copper alloy gate spool is provided.
The novel a kind of continuously casting copper alloy gate spool that provides of this use, comprise the graphite cast tubes, in graphite cast tubes outer setting the first fire-resistant mud layer is arranged, the described first fire clay layer thickness is the 3-10 millimeter, described fire-resistant mud layer is alternate along the thin and thick of graphite cast tubes peripheral direction, thin layer place thickness is the 3-5 millimeter, thick-layer place thickness is the 5-10 millimeter, the first alternate fire-resistant mud layer outer setting of described thin and thick has the second fire-resistant mud layer, the second fire-resistant mud layer seals the first flame retardant coating thick-layer place, and the thin layer place of first flame retardant coating forms along graphite-pipe runner longitudinally.
A kind of continuously casting copper alloy gate spool provided by the utility model, in graphite cast tubes outer setting fire-resistant mud layer is arranged, can block when casting graphite-pipe be directly exposed in the atmosphere, effectively improve the life-span of graphite-pipe, through cast tubes life-span of this outer setting flame retardant coating of application in practice generally about 100 hours, the GN 2 flow channel that is set to seal at flame retardant coating, when casting, feed nitrogen, cast tubes temperature and atmosphere all had the improvement effect, can further improve more than service life to 200 hour of cast tubes, this cast tubes long service life, make simple, with low cost, easy to use, in the copper smelting process, use and to effectively reduce the spare part expense, enhance productivity.
Description of drawings
Fig. 1 is the novel longitudinal cross-section schematic diagram that first flame retardant coating is set of this use.
Fig. 2 is the novel transverse sectional view that alternate first flame retardant coating of thin and thick is set of this use.
Fig. 3 is the novel transverse sectional view that is provided with second flame retardant coating of this use.
The specific embodiment
In order to explain enforcement of the present utility model more fully, provide embodiment of the present utility model.These embodiments only are the elaborations to this device, do not limit scope of the present utility model.
As accompanying drawing 1, Fig. 2, shown in Figure 3, a kind of continuously casting copper alloy gate spool, comprise graphite cast tubes 1, in graphite cast tubes 1 outer setting the first fire-resistant mud layer 2 is arranged, described first fire-resistant mud layer 2 thickness are the 3-10 millimeter, described fire-resistant mud layer 2 is alternate along the 1 peripheral direction thin and thick of graphite cast tubes, thin layer place thickness is the 3-5 millimeter, thick-layer place thickness is the 5-10 millimeter, among Fig. 2,2-1 is the thin layer place, 2-2 is the thick-layer place, and first alternate fire-resistant mud layer 2 outer setting of described thin and thick have second fire-resistant mud layer 3, the second fire-resistant mud layers 3 that first flame retardant coating, 2 thick-layer places are sealed, the thin layer place of first flame retardant coating 2 forms along graphite-pipe runner longitudinally, and 4 are depicted as one of them runner among Fig. 3.Runner can be connected with nitrogen pipeline.A kind of continuously casting copper alloy gate spool provided by the utility model, in graphite cast tubes outer setting fire-resistant mud layer is arranged, can block when casting graphite-pipe be directly exposed in the atmosphere, effectively improve the life-span of graphite-pipe, through cast tubes life-span of this outer setting flame retardant coating of application in practice generally about 100 hours, the GN 2 flow channel that is set to seal at flame retardant coating, when casting, feed nitrogen, can further improve more than service life to 200 hour of cast tubes, this cast tubes long service life is made simple, with low cost, easy to use, in the copper smelting process, use and can effectively reduce the spare part expense, enhance productivity.
After describing embodiment of the present utility model in detail, the personage who is familiar with this technology can be well understood to, can carry out various variations and modification not breaking away under above-mentioned claim and the spirit, any simple modification, equivalent variations and modification that all foundations technical spirit of the present utility model is done above embodiment, the scope that all belongs to technical solutions of the utility model, and the utility model also is not subject to the embodiment that gives an actual example in the specification.
