Problems solved by technology

[0004] At present, the traditional nailing device and method are limited by many conditions. People need to manually operate on site. When the steel nail is ejected on the surface of the slab, there is a certain degree of uncertainty. Improper operation will easily cause damage to on-site personnel and equipment. injury, high risk
Since there is no better method and equipment, we can only be vigilant at the scene, and the nailing operation is performed by professionals, but the danger cannot be ruled out

Embodiment

[0015] Using the device and method of the present invention, the 200mm×200mm square slab of GCr15 bearing steel produced by a certain factory is used for online measurement of the continuous casting slab solidification thickness measurement. The steps are as follows: ①Make a measurement plan before nailing, and calculate the trigger time of the measurement point; ②Set The nail shooting device is fixed on the side of the continuous casting slab to be measured, and the guide hole on the front end of the nail shooting device is vertically aligned with the continuous casting slab measurement surface; ③Turn on the power of the nail shooting device five minutes before firing; ④Operation Evacuate the personnel and on-site personnel to a safe area; ⑤ Turn on the power switch of the remote control one minute before the start of firing, count down, and wait for the firing command; ⑥ When the firing time is reached, press the firing button on the remote control to fire the nailing device; ...

Abstract

The invention discloses a remotely controlled continuous casting billet nail jet device and method, which belong to the technical field of continuous casting for steelmaking. The method is characterized by comprising the following steps of: fixing the nail jet device on one side of the to-be-measured surface of a continuous casting billet before start according to measurement requirements, and vertically aligning a guide hole in the front end of the nail jet device with the to-be-measured surface of the continuous casting billet; connecting a power supply of the nail jet device within five minutes before jet, wherein at the moment, operators and field staff withdraw to a safety zone; switching on a power switch of a remote controller within one minute before jet, counting down and waiting a jet instruction; and pressing down a jet button on the remote controller when the jet time is reached, and triggering the nail jet device to make special steel nails enter the billet. The device can perform accurate remote control operation on the continuous casting billet nail jet, and has the characteristics of scientific design, high safety, low billet loss and the like. The method is easy and feasible, and can realize safe and accurate operation according to different position measurement requirements.

Description

[0001] technical field [0002] The invention belongs to the technical field of steelmaking and continuous casting, and in particular provides a remote-controlled continuous casting slab nailing device and method, which is of great significance for studying the detection of the solidification process of steelmaking and continuous casting slabs. Background technique [0003] The solidification process of continuous casting slab is a complex physical and chemical change process, which has an important impact on the solidification structure of slab, internal cracks, segregation, porosity and surface quality of slab. The relationship with the slab solidification process has been extensively studied. The detection methods for the solidification process of the slab are mainly divided into the nail shooting method and the method of adding FeS to the crystallizer. The nail shooting technology uses a specific nail shooting device in the secondary cooling section to inject special ste...
