Description
Technical Field
The utility model relates to a copper alloy casting blank is with long casting chute temperature control device is applied to copper and copper alloy and smelts the casting field.
Background
In the process of producing the copper alloy by using the crucible furnace, as the casting launder is longer, the time for the copper water to reach the crystallizer through the casting launder after flowing out of the furnace mouth of the holding furnace is longer, the temperature of the copper water is reduced too fast, the casting structure of the copper alloy is influenced, microscopic and macroscopic defects are generated on the cast ingot, such as quality problems of internal air holes, external cast ingot cracking and the like, the yield of the copper alloy product is greatly reduced, and the economic loss is caused for a company. At present, there is no good solution.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that needs to solve is, overcomes not enough in the background art, provides a copper alloy casting blank is with long casting chute temperature control device rational in infrastructure, that keeps warm effectual and be convenient for maintain.
The utility model discloses a specific technical scheme is: a long casting runner temperature control device for a copper alloy casting blank comprises a natural gas guide pipe, a compressed air guide pipe, a direct flame burner, an igniter, a runner cover plate, a blast furnace runner, a contact type temperature monitoring device and a casting flow control device. The natural gas conduit is arranged on the direct flame burner and is fixed by an outer hexagonal screw; the compressed air conduit is arranged on the direct flame burner and is fixed by an outer hexagonal screw; the straight flame burner is assembled on the special burner positioning runner cover plate by using an outer hexagon bolt and a burner positioning transition plate; the igniter is arranged on the inner wall of the direct flame burner by using an outer hexagon bolt, and the mixed gas of natural gas and air is ignited; the chute cover plate covers the blast furnace chute and is fixed on iron plates at the two side parts of the blast furnace chute by positioning pins; the blast furnace launder is a main structure for bearing all devices and is also a diversion trench in a copper alloy liquid state; the contact type temperature monitoring device is arranged on a blast furnace runner and used for monitoring the temperature of copper alloy liquid in the runner in real time; the casting flow control device is fixed at the tail end of a blast furnace launder by using an outer hexagon bolt, and is arranged behind the contact type temperature monitoring device and right above the crystallizer.
The utility model has the advantages of reasonable structure, good heat preservation effect and convenient maintenance.
Drawings
FIG. 1 is a schematic structural view of a long casting runner temperature control device for a copper alloy casting blank;
description of reference numerals: 1. the device comprises a natural gas conduit, 2 a compressed air conduit, 3 a direct flame burner, 4 an igniter, 5 a launder cover plate, 6 a blast furnace launder, 7 a contact temperature monitoring device and 8 a casting flow control device.
Detailed Description
The long casting launder temperature control device for copper alloy casting blank of the present invention is described in detail below with reference to the attached drawing 1.
A long casting runner temperature control device for a copper alloy casting blank structurally comprises a natural gas guide pipe 1, a compressed air guide pipe 2, a direct flame burner 3, an igniter 4, a runner cover plate 5, a blast furnace runner 6, a contact type temperature monitoring device 7 and a casting flow control device 8, wherein the natural gas guide pipe 1 is installed on the direct flame burner 3 and fixed by outer hexagonal screws; the compressed air conduit 2 is arranged on the direct flame burner 3 and is fixed by an outer hexagonal screw; the direct flame burner 3 is assembled on the special burner positioning runner cover plate by using an outer hexagon bolt and a burner positioning transition plate; the igniter 4 is arranged on the inner wall of the direct flame burner 3 by using an outer hexagon bolt, and ignites the gas mixed by natural gas and air; the launder cover plate 5 covers the blast furnace launder 6 and is fixed on iron plates at two side parts of the blast furnace launder 6 by positioning pins; the blast furnace launder 6 is a main structure for bearing all devices and is also a diversion trench in a copper alloy liquid state; the contact type temperature monitoring device 7 is arranged on the blast furnace launder 6 and used for monitoring the temperature of the copper alloy liquid in the launder in real time; the casting flow control device 8 is fixed at the tail end of the blast furnace launder 6 by an outer hexagon bolt, behind the contact temperature monitoring device 7 and right above the crystallizer.
The device increases heat or reduces heat in real time by controlling the supply amount of natural gas according to the temperature change of copper alloy liquid in the runner so as to realize the temperature control of the long casting runner for the copper alloy casting blank.
In addition to the technical features described in the specification, the technology is known to those skilled in the art.
