Problems solved by technology

[0004] The purpose of this invention is to provide a new type of molten steel sampler for separating steel slag to solve the problem that the traditional sampler has a complex structure, and the sampling operation has high requirements on the site environment. When the steel slag cannot be directly isolated, it can go deep into the molten steel to sample, and it can be quickly used for the detection of inclusions. Analytical Testing Questions

Embodiment Construction

[0017] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] Such as Figure 1 to Figure 3 As shown, a kind of novel separation steel slag molten steel sampler of the present invention comprises sampler body 1 and wooden cover body 3;

[0019] The wooden cover 3 is arranged on the sampler body 1 by iron wire, the wooden cover 3 and the sampler body 1 form a closed cavity structure, the outer wall of the sampler body 1 is provided with an annular groove 2, and the edge of the wooden cover 3 There are at least one set of locking holes 4 symmetrically. The two ends of the iron wire pass through the locking holes 4 and are tied in the annular groove 2. The inner wall of the sampler body 1 is provided with a taper, the taper is 1.8, and the iron wire is pure iron or carbon. Steel wire, the material of the sampler body 1 is heat-resistant steel.

[0020] Further: a handle 5 is provided on one side of ...

Abstract

A novel separated steel slag and molten steel sampler belongs to the molten steel sampling technology field. A traditional sampler has a complex structure and sampling operation has a high requirementto a site environment. The invention aims at solving the above problems. A wooden cover body is arranged on a sampler body through an iron wire, the wooden cover body and the sampler body form a closed cavity structure, and an outer wall of the sampler body is provided with an annular groove. An edge of the wooden cover body is symmetrically provided with at least one group of lock holes. The twoends of the iron wire pass through the lock holes and are tied in the annular groove. An inner wall of the sampler body is provided with a taper, and the taper is 1.8. The iron wire is pure iron or carbon steel wire. The novel separated steel slag and molten steel sampler can directly take samples in molten steel under a condition of isolating from steel slag, and can be directly used for analysis and inspection of inclusions or inspection after processing.

Description

technical field [0001] The invention relates to a sampler, in particular to a novel molten steel sampler for separating steel slag, belonging to the technical field of molten steel sampling. Background technique [0002] Non-metallic inclusions are extremely harmful to the quality of steel products. It is very important to reduce and improve non-metallic inclusions in steel and improve the quality of steel. In the process of electric furnace and converter steelmaking, from tapping to refining, the contact time between molten steel and refractory materials in continuous casting is long, there are many opportunities for secondary oxidation, and the deoxidation and slag blocking in the tapping process are not perfect, so the molten steel is easy to be polluted . With the progress of the steelmaking process, some inclusions collide and float up, resulting in changes in the type, distribution and size of inclusions in molten steel. The commonly used method is to take samples fr...
