The high-temperature melt splashing in the copper launder can be effectively prevented from contacting the water inlet pipe and the water return pipe, the interface part and the metal hose through the protection device, and the interface part and the metal hose are prevented from being burnt and scalded by the high-temperature melt. And when the copper launder water supply system is discharged, the safe operation of the copper launder water supply system is ensured, and the safety risk of explosion after the high-temperature melt contacts with the leaked cooling water in the cooling water pipe is eliminated.
Description
Technical Field
The utility model relates to a method for preventing high-temperature melt splashed from a discharge launder from burning and scalding a cooling water pipe of the discharge launder in the process of discharging the melt of a metallurgical furnace.
Background
With the growing maturity of copper water jacket manufacturing and processing technology in the metallurgical industry, the metallurgical kiln melt discharge launder adopts a copper water jacket segment (hereinafter referred to as copper launder) to become a new technology, and replaces the original discharge launder with graphite or refractory material masonry mode. In order to improve the service life of the copper launder, the thermal deformation of the copper launder under the condition of high-temperature melt scouring and erosion needs to be eliminated, and the copper launder generally adopts a mode of internally introducing water for cooling. The cast copper buried pipe type copper launder is provided with water inlet and return pipe threaded connectors at two sides of the launder, and is connected with a furnace cooling water pipe network through a metal hose, so that the purpose that the copper launder is cooled through circulating water and the service life is prolonged is achieved. When the copper launder carries out the fuse-element emission, because of the fuse-element flow rate is fast, the fuse-element very easily splashes to outside in the copper launder, causes burning loss to copper launder business turn over water pipe interface part and metal collapsible tube, and explosion takes place after the cooling water contact that high temperature fuse-element and condenser tube were revealed, exists very big security risk.
Disclosure of Invention
In order to solve the problems in the melt discharge process and avoid the safety risk, the utility model provides a reliable melt discharge launder cooling water pipe protection device.
The utility model adopts the following technical scheme: the protection device for the cooling water pipe of the melt discharge launder of the metallurgical furnace comprises a connecting section, a protection section and a fixing section, wherein the connecting section and the protection section are integrally arranged, the connecting section is placed at the top of the groove wall of the copper launder, and the protection section extends outwards along the width direction of the copper launder; one end of the fixing section is buckled and pressed on the connecting section, and the other end of the fixing section is provided with a jacking bolt and is fixedly connected with the copper launder through the jacking bolt.
In order to ensure that the protection device is stably installed, the longitudinal section of the connecting section is L-shaped, and the width of the connecting section is 0.8-1 times of the width of the top of the groove wall of the copper launder. The longitudinal section of the fixing section is C-shaped, and the size of the opening is not smaller than 2-3 times of the thickness of the top of the groove wall of the copper launder.
The protection section is in a straight shape in order to protect the metal hose and the connector connected with the bottom of the copper chute, and the width of the protection section is not less than half of the width of the copper chute.
The beneficial effects of the utility model are as follows: when the melt is discharged, the protection device can effectively prevent the high-temperature melt splashed in the copper launder from contacting the water inlet pipe, the water return pipe, the interface part and the metal hose, and prevent the interface part and the metal hose from being burnt and scalded by the high-temperature melt. And when the copper launder water supply system is discharged, the safe operation of the copper launder water supply system is ensured, and the safety risk of explosion after the high-temperature melt contacts with the leaked cooling water in the cooling water pipe is eliminated.
Drawings
Fig. 1 is a schematic structural view of the present utility model.
In the figure, a 1-copper launder, a 2-connecting section, a 3-protecting section, a 4-fixing section and a 5-jacking bolt.
Detailed Description
The utility model is further explained below with reference to the drawings.
The protection section 3 and the connection section 2 (the connection section is generally made of angle steel, the angle steel is selected to be matched with the width dimension of the top of the copper launder, and the protection section is made of a flat steel plate) are welded, the fixed section 4 (the fixed section is generally made of channel steel, the channel steel is selected to be matched with the thickness dimension of the top of the copper launder, and the clamping and pressing are performed) is used for fixing the welded protection section 3 and the connection section 2 at the outer edge of the upper part of the copper launder 1, and the fixed section 4 is fastened at the outer edge of the upper part of the copper launder 1 in a jacking bolt 5. Through the mode, the protection device can be arranged at the outer edge of the upper part of the copper launder 1, the mode has the advantage of easy disassembly and assembly when overhauling or replacing the copper launder, the protection device does not completely wrap the cooling water pipe interface part and the metal hose, and in production, post personnel can conveniently carry out point inspection on the running conditions of the interface part and the metal hose, and if leakage occurs, the device can be found and processed in time. During discharging, the high-temperature melt sprayed out is isolated by the protection plate, and cannot contact the water inlet and return pipe interface part and the connecting metal hose below, so that the safety risk of explosion after the high-temperature melt contacts with the leaked cooling water in the cooling water pipe is eliminated.
