A kind of copper iron water jacket and casting molding method thereof

Abstract

The invention discloses a copper iron water jacket and a casting forming method thereof. The copper iron water jacket comprises a matrix, wherein a red copper pipe is arranged in the matrix and connected with a water inlet pipeline and a water outlet pipeline; a steel plate frame integrally formed with the matrix is arranged in the matrix and formed by mutual butt joint of steel plates arranged in the matrix and integrally formed with the matrix; claw nails are welded on the steel plates. The casting forming method of the copper iron water jacket comprises the following steps: modeling, embedding the steel plates, bending a pipe, preheating, embedding the red copper pipe, melting, pouring, unpacking, sawing a casting head, machining, polishing and applying for inspection of finished products. According to the invention, the advantages of the copper water jacket and the iron jacket are integrated into a whole, so that not only does the copper iron water jacket have better structural strength and long service life, but also the copper iron water jacket is good in heat-conducting property and cooling effect.

Description

technical field [0001] The invention relates to a copper water jacket used on a metallurgical furnace and a high-temperature furnace, in particular to a copper-iron water jacket and a casting method thereof. Background technique [0002] Copper water jacket is a cooling water jacket made of copper, which is used for cooling equipment on metallurgical furnaces and high-temperature furnaces, including wall bodies, water inlet pipes and water outlet pipes. Cooling copper pipes and cooling copper pipes are arranged in the wall body. It is an integral structure with the water inlet pipe and the water outlet pipe. It uses water as the heat exchange medium and uses the thermal conductivity of copper to transfer the temperature of the metallurgical furnace body. It is an important cooling device on the metallurgical furnace. Widely used in the metallurgical industry. [0003] Compared with molten iron jacket, copper water jacket has better thermal conductivity, better cooling effec...

AI Technical Summary

Problems solved by technology

However, since the melting point, thermal conductivity, linear expansion coefficient and mechanical properties of copper and iron are very different, the steel frame and wall are prone to defects of poor bonding.

[0005] At the same time, the common copper water jacket manufacturing method is used to manufacture the copper-iron water jacket, which is likely to cause the following problems: First, during the cooling process of the copper-iron water jacket, there is a serious tendency to crack at the joint surface between the embedded steel plate and the copper body

The second is that at the corner of the steel plate, warping is prone to occur due to shrinkage

Both of these problems will make the plate frame and the wall poorly combined, affecting the connection strength between the two
