A kind of molten steel sampler and using method thereof

Abstract

A liquid steel sampler and its use method. The lifting platform of the sampling instrument is located in the ground foundation pit on the side of the ladle, the mechanical arm is installed on the lifting platform through the rotary platform, the molten steel sampler and the steel slag sampling box are connected to the mechanical The arms are connected. The method of use is as follows: the mechanical arm is lifted above the ground and unfolded; the sampling adapter rod is installed; the molten steel sampler and the steel slag sampling box are installed; the mechanical arm is rotated horizontally so that the molten steel sampler and the steel slag sampling box are located directly above the molten steel sampling position; The forearm of the mechanical arm is retracted and the large arm is horizontal to measure the distance between the molten steel sampler and the liquid surface of the molten steel; the forearm of the mechanical arm is extended downward, and the molten steel sampler is extended into the molten steel to the sampling position to complete the sampling of the steel sample; the steel slag sampling box is moved down to make The box cover is immersed in the steel slag layer to complete the slag sample sampling; the forearm of the mechanical arm is retracted, and the molten steel sampler and the steel slag sampling box are separated from the liquid steel surface; the steel sample and slag sample are sent for inspection; It is folded and lowered back into the foundation pit on the ground, and the foundation pit is closed by the cover plate.

Description

technical field [0001] The invention belongs to the technical field of iron and steel smelting, and in particular relates to a liquid steel sampler and a using method thereof. Background technique [0002] In the iron and steel smelting process, analyzing the composition of steel samples and slag samples is one of the important means to guide the accurate operation of operators. On the basis of ensuring the sampling quality, how to complete the sampling quickly and safely is to determine the smelting cycle. key factor. [0003] At present, in iron and steel enterprises, the sampling process of steel samples and slag samples is carried out separately. When taking a steel sample, the fore-furnace worker usually holds a long iron rod, and a sampler is inserted into the end of the long iron rod, and the sampler is inserted into the molten steel for direct sampling. When taking the slag sample, directly insert the end of the long iron rod into the slag layer, and when the long ...
