Embodiment Construction

[0015] refer to figure 1 , 2 , 3, 4, a detection tool and detection method thereof for mold mold slag, made up of copper tube 7, wooden clip 6, plank 1, iron nail 5, copper-plated iron wire 4, copper tube 7 is long 0.7m, diameter It is 1 point, the diameter of the copper-plated iron wire 4 is 2mm, the length × width × thickness of the wooden board 1 is 70mm×50mm×15mm, the wooden clip 6 is fixed on the wooden board 1 by the iron nail 5, and there is a wooden clip spring 3 on the wooden clip, and the wooden board 1 The center is drilled with a through hole 2, and the diameter of the through hole 2 is 3mm. Copper-plated iron wire 4 is worn in the copper pipe 7. The copper-plated iron wire 4 is fixed by wooden clips 6, and then passes through 80mm from the through hole 2 in the center of the plank 1. During detection, the steel pourer holds the copper pipe 7 with his hand, inserts the copper-plated iron wire 4 passing through the wooden board 1 into the molten steel of the crysta...

Abstract

The present invention is protecting slag detecting tool and method for detecting the thickness of the liquid slag layer, the sintered layer and the powder slag layer of the protecting slag in crystallizer of continuous slab casting machine. The detecting tool consists of copper pipe handle, wood or asbestos board, wooden clamp on the board, iron nail, and copper coated iron wire or one iron wire and one copper wire in the same length through the copper pipe and the board. During use, the copper coated iron wire or the iron wire and copper wire is inserted into molten steel inside the crystallizer for 4 sec before being withdrawn while the board is floated on the molten steel surface. The thickness of the liquid slag layer, the sintered layer and the powder slag layer is detected based on the corrosion and color change of the copper coated iron wire or the iron wire and copper wire. The detecting tool of the present invention has the service life as long as 600 heats of steel.

Description

1. Technical field: [0001] The invention relates to a detection tool and a detection method for cast steel mold slag, in particular to a detection tool and a detection method for mold slag of a slab continuous casting machine. 2. Background technology: [0002] The mold slag structure in the crystallizer of the slab continuous casting machine is powder slag layer, sintering layer and liquid slag layer from top to bottom. The main functions are: heat insulation and heat preservation; air isolation to prevent secondary oxidation of molten steel; ; Form a layer of protective film between the mold wall and the molten steel solidification shell to reduce the drawing resistance; prevent the molten steel solidification shell from adhering to the crystallizer wall, forming an adhesion breakout; fill the air gap between the molten steel solidification shell and the mold wall , Improve the heat transfer conditions of the crystallizer, prevent breakout and slab defects. During the bil...
