Problems solved by technology

Most of the currently used copper launders are made of refractory bricks or graphite. The former is difficult to remove slag and the labor intensity is high, while the latter is easily damaged and has a short service life. At the same time, the copper cooling plate and copper cooling wall are manufactured by rolling and perforating. , the manufacturing cost is high, the investment is large, and it is impossible to manufacture copper cooling plates and copper cooling walls with special shapes such as circular arcs according to actual needs

Embodiment 1

[0011] Example 1: First use graphite to make the copper launder casting mold, and at the same time, pre-treat the copper tube and fill the inner cavity of the copper tube with laminating sand. After drying, the copper tube is dropped into the cavity, and then vertical pouring is used The process is casting and forming. The temperature is controlled at 1090°C--1140°C during casting. After forming, take out the copper launder body and clear the sand in the copper tube.

Embodiment 2

[0012] Example 2: First use graphite to make a copper cooling plate casting mold, and at the same time pre-treat the copper tube and fill the inner cavity of the copper tube with laminating sand. After drying, the copper tube is dropped into the cavity, and then the vertical casting is performed The process is casting and forming. The temperature is controlled at 1090°C-1140°C during casting. After forming, take out the copper cooling plate body and clear the sand in the copper pipe.

Abstract

The invention relates to a copper cooling piece making method used in metallurgical furnace and high-temperature furnace, especially a buried-tube type copper cooling piece making method, adopting graphite as casting mould, and at the same time, preprocessing the copper tube and then filling the inner cavity of the copper tube with coated sand, drying and then dropping the copper tube in the die space, then use the lie-making and erect-burning process to cast and cast, where the casting temperature is controlled at 1090-1140 deg.C. The made copper cooling piece not only has good cooling effect, smooth inner cavity and small water resistance at the time of water cooling, but also can not leak water because in no need of welding water inlet and outlet tubes and stopper, largely enhancing product quality. And at the same time, it largely reduces production cost.

Description

1. Technical field [0001] The invention relates to a method for manufacturing a copper cooling part used in metallurgical furnaces and high-temperature furnaces, in particular to a method for manufacturing a buried tube type copper cooling part. 2. Background technology [0002] Copper cooling parts (including copper launder, copper cooling plate and copper cooling wall) are cooling devices used in non-ferrous and ferrous metallurgical furnaces and high-temperature furnaces. Most of the currently used copper launders are made of refractory bricks or graphite. The former is difficult to remove slag and the labor intensity is high, while the latter is easily damaged and has a short service life. At the same time, the copper cooling plate and copper cooling wall are manufactured by rolling and perforating. , the manufacturing cost is high, and the investment is large, and it is impossible to manufacture copper cooling plates and copper cooling walls with special shapes such as ...
