Problems solved by technology

However, due to the compatibility of composition and structure between the steel plate material used in the metal sample box and the smelted steel material, the composition of the sampling sample is affected by the composition of the metal sample box, and the sampling composition deviates, especially in special steel smelting. In technology, the requirements for composition control are extremely strict, and the sampling of metal sample boxes is not universal

Abstract

The sampler is composed of sampling box, cap of blocking dregs, guiding tube, consolidation subassembly and paper tube connector, or additional deoxidizer. The sampling box is in sampling room of the consolidation subassembly. Guiding tube is connected to the sampling room. The cap of blocking dregs is installed on external end of the guiding tube. Paper tube connector is installed on the consolidation subassembly. Sampling box is made of ceramics in various shapes needed. Materials of the box can be cordierite, mullite, Al2O3, SiO2 etc. degree of porosity is less than 50% in order to meet requirement of heat exchangers and heat shock. The sampling box is general to sample analysis technique, providing smooth surface of sample so as to reduce difficult to grind sample.

Description

technical field [0001] The invention relates to a molten metal sample sampler in the metal smelting process. Specifically, it is a ceramic sample box molten metal sample sampler. Background technique [0002] The development of metal smelting technology has formed a fast chemical analysis channel to control the accuracy of each process link and chemical composition in the smelting process at any time. In the iron and steel smelting technology, the iron and steel sample sampler is required to be able to directly take out the standard sample of the specified shape from the metal melt conveniently, and quickly transfer it to the laboratory department, and give the chemical composition data of each link in time through spectral analysis. guide the process. The basic requirements for the sample to be sampled: ① representative; ② no impurities and cracks; ③ shape specification, no bubbles and good compactness. [0003] At present, the steel sample device is composed of a metal ...
