Crystallizer copper tube mold water groove grooving process

Abstract

The invention provides a crystallizer copper tube mold water groove grooving process, and relates to the technical field of crystallizer copper tube machining. The crystallizer copper tube mold watergroove grooving process comprises the following steps that S1, a copper tube blank is selected, and is detected with a metal flaw detector, wherein the outer diameter of the copper tube blank is 190 mm * 190 mm, the inner diameter of the copper tube blank is 154 mm * 154 mm, and the wall thickness of the copper tube blank is 18 mm; S2, a copper tube blank core rod, namely an inner mold, is prepared, wherein the size of the core rod is 154 mm * 154 mm * 1200 mm, the radius R of the core rod is 8,000 mm, and the qualified copper tube blank is installed on the inner mold; S3, a copper tube blankgrooving mold is prepared, and special lubricating oil is applied to the grooving mold; and S4, a press machine is started to enable the copper tube blank to slowly pass through the grooving mold. According to the process, through the process of water groove grooving on the copper tube blank by utilizing the grooving mold, a crystallizer copper tube is formed by drawing in one step without addinga special grooving procedure, so that the efficiency is greatly improved, the cost is effectively reduced, and meanwhile, the water groove grooving process is simple in operation, and can realize large-scale production.

Description

technical field [0001] The invention relates to the technical field of crystallizer copper tube processing, in particular to a mold water tank opening process for crystallizer copper tubes. Background technique [0002] Since the birth of continuous casting technology in the iron and steel industry, through continuous innovation and improvement, the casting speed has also been continuously improved. The most advanced technology at this stage is to open a water tank on the outer wall of the copper tube of the crystallizer, and the cooling water flows from the water tank and the water jacket. Compared with water, it has a large heat exchange area and uniform cooling. Using the mold copper tube with open water tank can increase the continuous casting casting speed by more than 25%. Using the crystallizer with open water tank for continuous casting machines has become a future development trend.

Problems solved by technology

[0003] Mold copper tube is a kind of accessory used for cast steel continuous casting machine. It is caused by direct casting of molten steel in the mold copper tube. At present, although the crystallizer copper tube with open water tank has great advantages, the existing technology Among them, the processing technology of mold copper tube opening water tank generally uses a tool to open the slot, which is expensive and cannot be mass-produced, and has certain limitations
