Pin shooting platform device for accurately measuring thickness of continuous cast billet solidified shell and operating method thereof

Abstract

The invention provides a pin shooting platform device for accurately measuring thickness of a continuous cast billet solidified shell. The pin shooting platform device comprises a pin shooting gun and a shooting controller, and further comprises a pin shooting bracket, a horizontal cross beam mounted at the top of the pin shooting bracket, loop regulators mounted on the horizontal cross beam, and pin shooting gun carrying clamps mounted on the loop regulators, wherein a connecting sleeve sleeves the pin shooting gun; the pin shooting gun is mounted on the pin shooting gun carrying clamps; the loop regulators comprise a front loop regulator and a back loop regulator which are respectively arranged at the front part and the back part of the horizontal cross beam; regulator vertical grooves and regulator horizontal grooves are formed in the loop regulators; the regulator vertical grooves are connected with the horizontal cross beam in a sliding manner; and the regulator horizontal grooves are connected with the pin shooting gun carrying clamps in a sliding manner. According to the pin shooting platform device, the phenomenon that during the pin shooting process, the bracket is not firm and is uneasy to regulate is overcome, and the thickness of the cast billet shell is accurately determined, so that the technology is accurately optimized, and the product quality is improved.

Description

technical field [0001] The invention belongs to the field of metallurgy, and relates to a nail-shooting platform device for accurately measuring the thickness of a solidified shell of a continuous casting slab and an operating method thereof. Background technique [0002] At present, in order to maximize production capacity and efficiency while ensuring quality, domestic iron and steel plants are blind to whether the adjustment of the continuous casting process difference matches it. The continuous casting process is a very complicated solidification and heat transfer process. The solidification of the continuous casting slab is to gradually change the liquid into a solid along the liquid core in the solidification interval, and the crystal strength and plasticity in the liquid-solid fuzzy area around the liquid core are very small, and cracks are easily generated. The shell thickness in different regions of the slab and the length of the final liquid core directly reflect ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a nail-shooting platform device for accurately measuring the thickness of the solidified shell of the continuous casting slab, so as to overcome the fact that the steel nails fired by the nail gun fixed by the support frame of the existing nail-shooting platform deviate from the center of the slab. The nail gun cannot be adjusted flexibly, which is not conducive to the actual operation on site, resulting in the problem of inaccurate measurement of the solidification thickness of the casting slab at a certain point during the measurement of the solidification process inside the slab
